0.1 Who made ALL this?
My name is Brett Gmoser (silent G). I have a lot of free time on
my hands. I am a hard core Duke 3D fan, and I've played it non-stop
since the day it came out. I made levels for Wolf 3d, DOOM, DOOM ][,
HeXen and ROTT, so I figured, hey, why not make Duke 3D levels? Well,
I got my CD 2 days after it started shipping, and as soon as I fired
up the editor, I, just like you, figured out just how complicated Duke
levels can be. I spent day and night (really) figuring stuff out. As
it ended up, after just three days I found that I had a knack for
making Duke levels. I have 2 ISPs, and as I surfed through to Duke 3D
Editing folders on AOL, compuserve and the Apogee BBS, I saw people
were having trouble. So I decided to make this FAQ!
0.1.1 Ho do I contact the author?
Well, I prefer to get email through my internet account,
and the address there is "". I'm also
on AOL, my screen name there is "GutenTag11". You can find me
on the 3D Realms BBS as "gmozmer".
Here is a list of my current web sites:
My Duke 3D Site. Pretty good, if you ask me. :)
A page with lots of cheat codes, offers my program which is
called CHEATS!.
I wouldn't DARE give out the rest of the addresses because they
all suck....:)
0.2 What you should have gotten
In addition to this file (MAPFAQ01.FAQ), you should have gotten the
following things in the ZIP file (MAPFAQ01.ZIP):

0.3 Revision history
Well, since this is the first version of the FAQ, there is no revision
yet. Look for this section in future versions of this FAQ. Bet you
can't wait! :)
0.4 Thank-you's and Credits
First, I would like to thank 3D Realms for such a great game. Thank
you also to all the people that gave me support, and the people that
have this FAQ posted on their web page. I would like to give credit
to Per-Erik Nilsson for the dimensions facts, and tempest for making
great tutorials on how to make Star Trek Doors.

Thanks Guys!

1: Information About Maps

1.1 What are maps?
Maps are user levels for Duke Nukem 3D. They are in the same format
as the actual levels, and are fully customizable as far as levels go.
Map files are not only for Duke 3D, but the same format is used for all
of the games that use the Build engine. Build allows for many new things
like moving sectors, rotating sectors, parallaxing skies, slopes, and
lots of other stuff. The possibilities are endless!
0.1.1 What else can I do with MAP files?
Well, not much else. MAP files are not like DOOM's system where
you had WADs and PWADs. MAP files can only take in levels.
0.1.2 Can I extract the original .MAP files from the game?
Yes, you can. In the \goodies\build directory of your Duke 3D CD,
there is a program called KEXTRACT. Copy it to your Duke 3D
directory and use the following command:
This will extract all the original levels. Look at them and
see how much work was put into them...boy! :)
1.2 What do I use to make maps?
Currently, the only editor for build is BUILD by 3D Realms. It is the
official editor and was used to make all the real levels. How does one
obtain this editor you ask? That's simple. BUILD is on the CD that
registered Duke 3D comes on in the directory \goodies\build.
0.2.1 Can I make maps for other games?
No, not really. BUILD is made specially for Duke Nukem 3D.
You could probably make a simple one-roomer with no objects
or sprites, but nothing that good.


2.1 Ok, I have the editor, how do I use this thing?
Yes, at first, BUILD looks VERY complicated. It is used by with the
keyboard. Since you have the actual editor, and not a pirated editor,
you should have BUILDHLP.EXE in the \goodies\build directory of your
CD. It's the official BUILD handbook, please read this ENTIRE thing
to learn the basic keyboard commands.
2.2 First levels suck!
Lets face it, your first level IS going to suck. This happens to
everybody. I HIGHLY reccomend you make you first level suck on purpose.
This will get you used to the format and the way of doing things in
BUILD. So lets get started on our first horrible level!
2.3 Your basic, one-sector, horrible level
Now that you've read everything above this, it's time to make your
first level. We'll start off very basic, and move on to the cool
stuff. First, we'll make a one-sector room. Here's how:
First, make sure you are in 2D mode. (Since you've read BUILDHLP,
you know how to get there) Position the cursor somewhere on the
grid. BUILD automatically starts you out in the lower-right corner.
You shouldn't worry about this.....yet. Press the space bar to enter
line-draw mode. Move the mouse around, see what happens. Nothing
special, except that when you press the space bar again, this is where
the next line will start. For now, we'll just make a square room.
If you want, when you're done, you can position the cursor on one of
the vertexes, hold the left mouse button and drag the vertex around
to change how the room looks. Next, place the arrow somewhere in
the room, and press scroll lock. This puts the starting point in.
Pardon my artwork, but it should look something like this:

_____________________________ The -'s and :'s represent the lines,
: : and the --> is your starting point.
: :
: --> :
: :

At this point, you can save and run your level. Pretty cool, huh?
2.4 Your basic, two sector, horrible level
After you've tried your new one-sector level, fire up BUILD and go
to it. If we wanted to make and elevated surface in the middle of
the room for absolutely no reason other than to learn how, we would
place the cursor somewhere inside our sector, and draw a new box.
We'll call the box you just made "BOX B" and the other will be "BOX A"
It should look something like this:
: ________________________ :
: : : :
: : BOX B : :
: : : :
: :______________________: :
: BOX A :

Now, click on the outer portion, and enter 3D mode. Notice what it
did. You now have the new box as walls facing outward, and you can't
go in the box that you made. It's just walls. We could leave it like
that, but we want an elevated platform, right? So, go back into 2D
mode. Place the cursor inside BOX B. Now, hit ALT+S. Notice that
the lines that make up BOX B have turned red. This means that those
walls are "Two sided walls", and the box inside has now turned into
what is called "Valid player space". Go into 3D Mode, and watch what
happened. The room should look exactly like our one-sector room did.
Utterly useless, but read on....
2.5 Your basic, two-sector, not-so-horrible level
Ok, as I said, we are going to make an elevated surface. But we just
GOTTA do some other things, right? :)
2.5.1 Floor/ceiling heights
Go into 3D mode now, and point the mouse at BOX B. To make BOX B
elevate, use the PAGE UP and PAGE DOWN keys. Try it with BOX B's
floor and ceiling, along with BOX A's floor and ceiling. Our surface
is now elevated.
2.5.2 Changing textures
Well, we have our cool floor and ceiling heights, but we have
to do something with that ugly grey texture. Well, here's how:
Point the mouse to the texture you want to change. Hit the 'V'
key. You will now have a screen with that ugly texture, and
you can go down and see the names of everything else. It's
like this because that's the only texture we've used. Later,
when we use more, the ones we use will show up automatically.
Anyway, for now, we want pictures. So go ahead and hit the 'V'
key again to get all of the items. Scroll down till you find
a cool texture, and hit enter. The wall has now changed textures. Panning and stuff
Texture panning is a great feature. You can scroll a
wall up and down, possibly to meet other textures on
either side. To do this, go into 3D mode. Point to
the texture you want to pan. Next, hold down the shift
key and use the arrows on the number pad to pan. Cool?
You can also shrink and enlarge the texture (this also
works for sprites) by using just the arrow keys. If you
ever totally mess up a wall, you can get it back by
pressing /. If you like the way you panned or shrunk a
wall, you can hit the > key to do it all around.
2.5.3 Skies
If you tried to change the ceiling to a sky, and it looked
all wrong, you can fix that very easily. In 3D mode, point
to the sky, and press the 'P' key. This is called parallaxing.
It makes the ceiling (or floor for a neat effect) look like it
arches and goes forever. Very cool stuff....
2.5.4 Shading
Well, to make it darker, all you have to do is point at a
texture and hit the + and - keys on your numeric pad. To make
the whole room dark, just shade all the walls.
2.5.5 Slopes
Slopes are quite easy, actually. All you do is go into
3D mode and point at the wall/ceiling you want sloped. Then,
use the [ and ] keys to slope. That's it!

3.1 Intro
First off, please do not proceed unless you have read and
done all of the above, or you will not understand anything
below this. Deal? Ok. Second, PLEASE read the following
part... because if you understand it, you will be able to
do this stuff ALL on your own. :)
3.2 Hitags and Lotags
These are some of the hardest things to explain. I'm going
to explain it like this: Lotags are usually defined by the
game, and they describe how something is going to act. Lotags
can be changed by placing the cursor on what you want to change
and pressing 'T' for sectors, and 'ALT+T' for sprites. Hitags
are usually defined by the user. They explain where something
is going to go to, or what's going to activate it. For example,
it could be where a teleporter is going to teleport to, or what
switch a conveyor belt is going to stop for.
3.3 Sector Effectors
Sector effectors are just what the name says. They say what
will happen to a sector when you blow that crack, flip that
switch, open that door, or activate that touchplate. They
need Hitags and Lotags to go with them.
3.4 Locators
Locators can determine where a Recon Control Vehicle goes
or where a subway turns or goes. You get the idea.
3.5 Music & SFX
One really good thing about Duke 3D is that YOU define the
sounds that a door, lift, or just about anything for that
matter makes. Use this to say what sound these things make
when used. Stuff like switches, teleporters, and other things
do NOT need this.
3.6 Checklist
There are a bunch of things you must do before you make/upload
a level. Here's a checklist:
Before starting on your level:
[ ] I am comfortable with the editor I am using
[ ] I have made my first level, and it sucks
[ ] I have a good theme for my level
[ ] I have planned it all out
[ ] I have read this ENTIRE FAQ through, and understand how to do
[ ] I understand everything talked about in section 3
Before Uploading your level:
[ ] I have filled out a MAP authoring template
[ ] I have a story line
[ ] I have gone through EVERY part of my level so many times that
I think I'm going to kill myself.
[ ] I have had other people use my level
[ ] I have tested my level using multiplayer


4.1 Intro
Again, as before, PLEASE do not advance to this part of level making
unless you have read and understood everything above it. :) This is
because this section will be the part where you really make your two-
sector level AWESOME. It is the stuff that was used in the real levels,
and I'm going to explain to you exactly how to do everything. If in
doubt, I have provided separate .MAP files for each technique, and near
each set of directions, I have put what .MAP file to look in.
4.2 Teleporters

Teleporters are some of the easiest hard things to make in Duke 3D,
so we'll start with them first. First, make the following room:
: : We'll call this fig. a. The
: : outside box is just your normal,
: : basic room. Make the two inner
: : Sectors (marked with a "T") valid
: ___ ___ : Player space. If you want to make
: : T : : T : : it look good, put the grid size on
: :___: :___: : the biggest one, and line up the
: : "T" sectors with the grid. Use the
:__________________________________: teleporter tile for the floor, and
raise the floor. The next step is the hard part. Place a sector-
effector sprite in the middle of each of the "T" sectors. Since this
is your first teleporter, make the Hitag for this sprite 1, and the
Lotag 7. 1 is because this is your first teleporter, and if you made
another, you would change it to 2. 7 is because that is that is the
Lotag for teleporting. That's it!

Note that whatever angle the sector-effector sprite is facing is
the way that the player is facing when he/she comes out of the
teleporter. You could have the player come out facing a wall with
10 aliens to his back...but you didn't get that idea from me! :)
4.3 Water
Map name: WATER.MAP
Like teleporters, water is very easy. First, make a square sector.
Put another sector in the middle of it, this will be the top of the
water. Next, make a sector anywhere (except in the outer part of
the first one). One thing you must make sure of is that both of the
inner sectors are the same EXACT size, and that they are valid player
space. When you're done, it should look like this:
Now comes the hard part. We're working
____________ now with the inner sector, since that is
:______B_____: the water. Sector A is going to the top
of the water, so change that SECTOR's
Lotag to 2. This signifies that this sector
__________________________ will be "on top" of the water. Do the
: : same thing to sector B, but make the Lotag
: ______________ : 1. This tells the game that this sector will
: :______A_____: : be underwater. Next, put sector-effectors
: : in the same place of sector A and sector B.
:_________________________: Just like teleporters, this is your first
piece of water, so make the Hitag for both sector-effectors 1, and the
Lotag 7. That's it!
4.4 Lifts
There are four different kinds of lifts:
1. Starts at top, comes down. Ceiling stays put.
2. Starts at bottom, comes up. Ceiling stays put.
3. Starts on top, floor and ceiling come down together.
4. Starts on bottom, floor and ceiling come down together.
These are pretty easy to make. I would guess you know how to arrange
the sectors (if not, look at LIFTS.MAP). Here's how you make the
All Hitags are zero, so put the following #'s for Lotags:
1. 16
2. 17
3. 18
4. 19
For best effect, put a MUSIC&SFX sprite in the lift sector, make
the Hitag and Lotag (For MUSIC&SFX sprite) 73 for Hitag, 71 for Lotag.
4.5 Glass
Glass, believe it or not, is fairly easy. The procedure is as
Make the following rooms:
__________ _________
: : : : The sector in the middle should be valid
: :_: : player space. Next, go into 3D Mode.
: : : : Point the cursor to the ceiling of the middle
: : : : sector, and press 'M'. An ugly brown texture
: :_: : will apear. Press 'V' on this texture and
: : : : select the glass texture. Next, go into 2D
:_________: :________: mode. Point to the line with the glass
texture. Press 'B' to make it so you can't walk through the glass,
and CTRL+H to make the glass breakable. You've got yourself a new
4.6 Vents
Map Name: NONE
There's no map for this because it is so easy. All you have to do
is the EXACT same as above, only substitute the glass texture for
a vent, and make the sector behind the vent have that metal texture
in all vents. You might want to size down the second sector to make
it look something like a vent. :)
4.7 Security Cameras
Look at CAMERA.MAP for this one. Pretty self explanitory. :)
NOTE: The Hitags on cameras are how much they will turn from their
original starting position. Experiment!
4.8 Regular, DOOM-Type Doors
Map Name: NONE
This is easy. I'm sure you know how to make doors in DOOM. Make
3 sectors, the one in the middle is your door. Make the ceiling
come down to the ground. Add nice textures, put a Sector Lotag
of 20 for the door sector. That's it!
4.9 Collapsible Bridges/Bridges
Bridges, despite what you might think, are extremely easy. A
bridge is actually a sprite. (Check BRIDGE.MAP for sprite #)
To make the bridge collapsable, like in E1L1, give the bridge
sprite a Hitag. It doesn't matter what number, as long as it
is unique to that bridge.
NOTE: You may have to use the 'R' key on the bridge sprite to
get it the way you want it.
4.10 Dukematch/Co-op ONLY Stuff
Map Name: NONE
To make an object appear only in Dukematch or Co-op play, go into
3D Mode. Point to the sprite with the cursor and hit the RALT+P
keys. (This is to change the palette) Type in '1' to make the
object "Dukematch-only". That's it!
4.11 Fun With C-9
Map Name: HOLE.MAP
C-9 is the source of most of the explosions in Duke 3D. Here are some
A.) If you shrink C-9 (Use > and < keys on numberpad in 3D Mode) all
the way (widthwise), when you play the game you do not see it. It
can still be operated, but only by an OOZCAN, another C-9, or a crack.
B.) A C-9 sprite can be activated by an OOZCAN, crack, or another C-9.
C.) You can have a Dukematch-Only hole by making the crack Dukematch-
only. (See 4.10)
Well, that's it for the mile-long fact list...:) Now, to be able to
blow holes in walls....
Step 1: Make the following sectors:
: :
: :____
: :_A__:
: :_B__:
: :_C__:
: :
: :
Sectors A, B, and C should be all valid player space. We could have
sectors A, B, and C as all one sector, but we want our hole to look
cool. So make it 3, and arrange the slopes of the floor and ceiling
and the heights of the floor and ceiling until you've got a nice hole.
Add nice textures, the stuff inside the hole will be what it looks like
when blown out.
Step 2: Put a crack sprite somewhere. It really doesn't matter where,
it'll work just the same. I prefer in front of the hole. :) Make sure
that it's directly on a wall, though. Give the crack a Hitag.
Something unique, not the same as any other cracks. I used 213 in
my map.
Step 3: Place a Sector Effector *Sprite* in sectors A, B, and C.
Give them your unique Hitag, and a Lotag of '13'.
Step 4: Place a C-9 sprite in sectors A, B, and C. Now, go into 3D
mode. Use the '4' and '6' keys on your NUMBERPAD to shrink the C-9
WIDTHWISE as much as possible. If you don't know what I mean, look
at my map.
Step 5: Go back into 2D mode. Give each of the C-9's your special
Hitag. Now, the Lotag for the C-9's is up to you. That determines
how long it will be before the C-9 blows up. You can have it happen
right away, a long way away so the player walks up to the hole and has
C-9 blown up in his face, or all three go at different times. For now,
just put 20 for the middle one, 40 for the left one, and 60 for the
right one. This makes a nice explosion, and is not bad for a
beginners hole.
Step 6: You're done! Play the level! In future hole designing, you
might want to know this:
1. You can have the crack shatter as many sectors as you want, just
make sure they are of all equal Hitags.
2. If you want a HUGE explosion that'll last about 10 seconds, fill
the ENTIRE room with C-9, shrink them all, and give them your
Hitag. Set them all for different times, and watch it blow! Set
records for how long you can stay alive with C-9 blowing up in your
3. Have JUST C-9 blow a hole by replacing the crack with a C-9
sprite. Make sure it's not on the wall, and KABOOM!
4. Use KEXTRACT to extract the original levels, get ideas from them.
4.12 Swinging Doors
These are EXTREMELY hard at first, but when you know how, you can
do it with the snap of a finger. I recommend you follow these
directions and make your own before you look at the example, because
the example is very confusing.
STEP 1: Make the following sectors:
: :
: :
: :__________
: : :
: A : B :
: : :
: :_________:
: :
: :
They should be both valid player space, and the line separating them
should be red.
STEP 2: Now, we make the doors. This is the hard part. Go into
sector A and make the following:
: :
: :
: :
It is important that you realize that you must make the doors in a
valid sector. Doesn't matter which one, but a valid sector.
STEP 3: You should now have something like this:
: :
: :
: :__________
: : :
: A : B :
: ___ : :
: : : :_________:
: : C: :
: : : :
: :__: :
First, make sector C valid player space by moving the cursor in it
and pressing ALT+S. Give it a Lotag of '23'. Move the vertexes
over to where the door will be. The upper right vertex of sector
C should overlap the upper left corner of sector B. Sector C's right
line should overlap sector B's left one. Get it? I hope so. :)
STEP 4: Make another sector C, and place it below the old sector C.
The new sector C's bottom vertexes should overlap the new sector C's
top vertexes.
You should have this:
: :
: :
: _:__________
: : : :
: A :_: B :
: : : :
: :_:_________:
: :
: :
I hope you understand this part. If not, please look at SWDOOR.MAP.
If you still can't get it, send email to
I'll try to help you.
STEP 5: Now, the tricky part. You have to put a sector effector at
the pivot points of the two doors. Sound easy? Well, kinda, but
you have to get it just right. Turn grid locking off, and move the
sprite to the corner, but not ON the corner vertex. Just enough so
that it doesn't touch anything. Next, give the sector effectors a
unique Hitag, and a Lotag of 11.
STEP 6: For the next step, the docs appear to be wrong. They say
change the palette number of the sector-effector to change the
direction that the doors go, but actually, you have to point the
SE's the way you want. Check SWDOOR.MAP for more details.
STEP 7: Raise the floor of the door up to the ceiling, add nice
textures, and you're done!
NOTE: A door will not appear to work right when:
The floor/ceiling is sloped
The floor/ceiling is a different height than that of the
doors, from the beginning of the door to the end. (i.e. A
door will not work if swinging off a curb)
4.13 Rooms Over Rooms
Map Name: SOS.MAP
This is quite easy to do. First, make a big sector. Make the ceiling
high, choose some nice textures. Make a place leading from that, and
up a staircase or slope. Go around until you get to one of the sides
of the first sector. You should something like have this:
: ________________________ :
: : : :
: : :______:
: : 0 0
: : __________________________________________
: : : :
: : : :
: : : :
: :__: :
: :
: :
:________ :
: :
: :
: :
: :
Now, the two 0's are the ending vertexes for the sloped hallway. I
know they look nothing like it, but bear with me. :) Now, start
making a new sector, starting from the 0's. Make it inside the
first sector. DO NOT put vertexes on the lines for the first sector.
just let the lines overlap. Now, travel up your slope, and go
into the sector you just made. Right now, it's at regular floor height.
Just raise the floor, and you've got a sector over a sector! If you
need help, look at SOS.MAP.
4.14 Sliding Star Trek Doors
Sliding Star Trek doors, despite what you might think, are very easy.
But, they can be very hard to teach by way of directions. If in
doubt, look at SLSTDOOR.MAP. Pull it all apart.
These doors are just 2 sides that pull apart. An example from the
real game is the door leading out of the arcade in E1L1.
STEP 1: Make the following sectors:
_______________ ________________
: : : :
: : : :
: :___"___: :
: : : : : :
: : : : : :
: D : C:A:B : E :
: :__:_:__: :
: : " : :
: : : :
:______________: :_______________:
Ok, now. Sector A is what we will be working with. Insert 3 vertexes
on the bottom and top lines of sector A. If you're not sure what I
mean, the lines to insert the vertexes are marked with a ". They
should be side by side, parallel to each other.
STEP 2: Slide the two middle vertexes into the exact middle. They
should overlap. Next, take the top and bottom vertexes and slide
them on the line that separates setctor A from B, and A from C.
Again, if you don't know what I mean, look at SLSTDOOR.MAP.
STEP 3: You are now done constructing the door. Add some nice
textures. Now, go into 2D mode. Point the cursor to one of the
triangles that you made by sliding vertexes. Doesn't matter which
one, top of bottom. Hit the 'T' key and give it a Lotag of 9.
At this point, you can use your new door. To make the door nice,
put a MUSIC&SFX sprite and a GSPEED sprite in one of the triangles.
Give the GSPEED sprite a Lotag of 64, and the MUSIC&SFX sprite
a lotag of 259.
NOTES: 1.) The texture of the door will "squish" when it is opened.
No way around it.
2.) For some odd reason, the door's sound will play twice
when the door is opened. No way around this. :(
4.15 Splitting Star Trek Doors
These have got to be the COOLEST doors in the game, and they're
quite easy to make. Here's how:
STEP 1: Make a regular Star Trek Door. (See 4.14)
STEP 2: Go into 3D mode. Choose nice textures. Point the cursor
at the triangle part, and make the floor and ceiling meet in the
middle. Keep in mind that the floor and ceiling of the triangles
will be the floor and ceiling of the door sector when the door is
open, so choose a texture like 1156. You are now done constructing
the door. Just a few little things to go...
STEP 3: Go back into 2D mode. Point at one of the middle triangles.
Give the sector a Lotag of 26. At this point, your door is done.
To make it nice, add a GSPEED and MUSIC&SFX sprite. Give the GSPEED
sprite a Lotag of 128, and the MUSIC&SFX sprite a Lotag of 527. You're
4.16 Teeth Doors
Another cool door, and it's real easy to make.
STEP 1: Make the following sectors:
________________________ ______________________
: : : :
: : : :
: :_____________: :
: : _____ : :
: : :__B__: : :
: D : _____ A : E :
: : :__C__: : :
: :_____________: :
: : : :
: : : :
:______________________: :_____________________:
They should all be valid player space.
STEP 2: Raise sector A, B, and C's ceiling to match D and E's.
Leave sector A's floor alone, but make B and C's floor low enough
so that you can't see it, even looking down. Add nice textures.
STEP 3: Give sector A a unique Hitag, and a Lotag of 29. Place
one sector effector in sector B and C. Give the effectors the unique
Hitag you gave sector A, and a Lotag of 22. You're done! You might
want a MUSICANDSFX sprite with a Lotag of 166 in sector A, up to you.
4.17 Auto-Closing Doors
To make a door auto-close, put a sector effector in the door sector.
Give it a Lotag of 10.
4.18 Nuke Buttons
All you have to do for a Nukebutton is put the sprite (#142) on a
wall, and give it a Lotag of '32767'. Also, to end a level, put
a sectoreffector in a sector and give it a Lotag of '65535'. This
will end the level when the player walks on the sector.
4.19 Secret Areas
Map Name: NONE
To make a secret area, put a Sector Effector in the sector. Give
it a Lotag of '32767'.
4.20 Sound List
Map Name: NONE
I'm not going to list all of the sounds and what theydo here, at
least for now. You have a list of them in your Duke 3D directory,
though. Open up DEFS.CON. There is a list of all the sounds starting
at line number 646.
4.21 Mirrors
This is pretty easy to do. Before you do this, go into MIRROR.MAP.
Turn on no clipping (DNCLIP). Walk through the mirror. Weird?
This is a hall of mirrors effect, and you are actually in the
room behind the mirror. To make a mirror, make the following sectors:
: :
: : ________
: : : :
: :___: :
: : : :
: : : :
: : : :
: C : B : A :
: : : :
: :___: :
: : : :
: : :________:
: :
Sector C is the room behind the mirror. As a rule of thumb, it should
usually be twice as big as sector A, if not bigger. The mirror will
usually work if sector C is the same size as sector A, but sometimes
if you look in the mirror at different angles, it gets messed up.
Now, go into sector A, in 3D mode. Point to the ceiling of sector
B, and press the 'M' key. Change that ugly texture to the mirror
texture, which is number 560. Next, point to the new texture and
press the '1' key. This makes the wall 1-sided, and there will now
be a pink backround and you can't see into the other room. Next,
go into 2D mode. Point to the wall that the mirror will be and
press the 'B' key and 'CTRL+H' keys. This makes the wall block you
and hittable. If you want Duke to say "Damn, I'm lookin' good!"
when you use the mirror, give the wall (use ALT+T on the wall for
Lotags, ALT+H for Hitags) a Lotag of 252. You're done!
4.22 Conveyor Belts/Water Current
This is pretty easy. Note that to make water current, it's the same
deal, just put water on the floor and give the sector a Hitag of 1.
First, make your conveyor belt. Just a flat sector, maybe the
conveyor belt texture for the floor. Add a sector effector. Give
it a Hitag of 24, and point it the way you want the conveyor belt
to go. That's it! To make it go faster, put a GSPEED sprite in
the conveyor sector. Give it a Lotag of your choice. The higher
the Lotag, the faster it will go. Look at CONVEYOR.MAP to learn how
to make a switch turn it on and off. Pretty self-explanatory.
4.23 Gears
To make gears, make a gear sector. You know, make it look like a
gear. I didn't have the time nor the energy to make a whole lot
of prongs on my gear, so I just made a cross. Just the same. Anyway,
decide on a pivot point for the gear. Insert 3 sprites on the pivot
point. Go into 3D mode. Make 2 of them sector effectors, and one
sprite #418. Use relative alignment (R key) on sprite #418 to make
it lay flat. Go back into 2D mode. Give both of the sector effectors
a unique Hitag, not the same as all the other gears. I used 20. Then,
give one of the sector effectors a Lotag of 1. That's it! To make the
gear sound good, put a MUSIC&SFX sprite somewhere. Give it a Hitag of
8000, and a Lotag of 89. For multiple gears, do the same thing only
leave out the sector effector with no Lotag.
4.24 Subways
To make subway cars, first make a subway track. Doesn't have to be
too elaborate, something like a race car track. First, we'll make
the engine. Make a simple square sector, for our first subway.
Later, we can make bigger and better cars, but for now just use a
square. Make the square valid player space. Go into 3D mode. Go
into 3D mode and do anything you want to the car... i.e. make the
floor higher, put nice textures, etc. Next, put a sector effector
in the subway car. For the Hitag of that sector effector, we'll
use the number 1. 1 is because the subway is going to start at
locator number 1. For the Hitag of the sector effector, put a
6. 6 means that this is the engine of the train, and all cars will
follow it. Now, the locators. Put locators (sprite #6) around the track.
Each locator tells the car where to go next. Look at SUBWAY.MAP if
you need an example. Now, put Lotags on the Locators. It is
important that you DON'T give the first locator a Lotag, or the
game will crash. Give all the other locators Lotags going in
number order, from second to last. (Leave the first alone) You have
your self a subway! If you need more help, look at SUBWAY.MAP.
Now, if you wanted to make 2 cars, make another subway sector.
Give the sector effector (you do not have to make new locators)
a Lotag of 14 instead of 6. If you want to have multiple trains
on one track, give the first train SECTORs a Hitag of 1, the second
a 2, and so-on and so-forth. Also, to make it so the floor doesn't
move with the car, go into 3D mode and point to the floor of the car.
Press 'R'.
4.25 Colored Lights
To make colored lights, make a sector. Choose textures. Change the
palette number (use ALT+P) of the walls, ceiling, and floor to
a number from a list below. Next, add a sector effector. Change
the sector effector's palette, and give it a Lotag of 4.
The only palette numbers for lights that seem to work are:
1 = Blue
2 = Red
7 = Yellow
8 = Green
4.26 Demo Cameras
To make a camera in your level that will play back demos after
they are recorded, put a sector effector somewhere (preferably
where you want the camera :) ). Give it a Lotag of 27. The
Hitag is how far the camera can see. Experiment a bit.
4.27 Co-op/Dukematch Starting Points
To make co-op and Dukematch starting points, put a Duke sprite (his
initial frame) in your level. That would be a Dukematch start. To
make a co-op start, give Duke's sprite a Lotag of 1. Co-op starts
should all be at the beginning, with the player 1 start. Dukematch
starts should be where no player is at an advantage, i.e. near a
good weapon, etc.
4.28 Facts On Dimensions
This was taken from the Apogee message base, and was written by
Per-Erik Nilsson ( Everything is measured
in units up how many times you press the PGUP/PGDOWN keys. For the
shooting ones, aim up/down was not used.
Measure Duke Standing Duke Ducking
Min. height for Duke to enter a sector 11* 6
Max. height that Duke can walk onto 3 0
Max. height of floor Duke can shoot above 8(9)** 3(4)**
Min. height of ceiling Duke can shoot below 10(9)** 5(4)**
As above but using RPG 11 6
Max height of floor Duke can jump on to 20 0
Min. height of wall to place tripbomb on 10 4

* Duke can also enter sectors with a height of 10, but he will
automaticly duck.
** Second number is when only some of the shots will get past
