Tutorial

[Daniel Aquino]

I went through the tut and I kept getting a pink screen that froze...

I also got the error about the mesh on win32 machines which is noted
in the tutorial..

But the downloaded source of the dirty ruby tutorial seemed to give me
an ogre window with all blank values...

I tried to copy the mesh file over but it was to no avail..

Any ideas for me here ?

[Mikkel Garcia]

A couple of questions:

1. Are you on SR 0.5.0.2?
2. Does the screen freeze before putting the mesh on the screen?
   
3. Does pressing escape close the pink window?
   

We really need to update the tutorials, I'm guessing the demo is for version 0.4 (before the huge ogrerb revamp)

Thanks,
-Mikkel

> Are you on SR 0.5.0.2?

yes... just installed last night!

> Does the screen freeze before putting the mesh on the screen?

I believe it did but I will get back to you on that one...

> Does pressing escape close the pink window?

Will get back to you...

--------

What about the fact that the downloaded source of the tutorial gave me
an ogre window that didn't offer any selection values ?

[Daniel Aquino]

> Does the screen freeze before putting the mesh on the screen?

As I said the screen is frozen.

If I add the mesh then I get the mesh error and no screen ever shows up...

> Does pressing escape close the pink window?

Yes it closes...

[Mikkel Garcia]

Thanks for the quick response.

Ogrerb is running correctly (since you can use key :pressed) - could you post the code for the state?


Specifically, I want to see if your near distance, far distance, and camera position / look at are all setup.

BTW, the pink color is set in state by viewport.set_background_colour.  In the next release, I believe we'll change it to a less weird color (maybe ruby red or ogre green).


Thanks,

# The different types of scene managers provided by Ogre are:

scene_manager = create_scene_manager :general

camera = scene_manager.create_camera("camera")
camera.position = v(0,0,-200)
camera.look_at v(0,0,0)

viewport = create_viewport(camera)
viewport.set_background_colour Ogre::ColourValue.new(0.8, 0.5, 0.5)

# @ruby = DirtyRuby.new
end

I wanted to get in on this post as well. I am also having a bit of
trouble with the tutorial. I can get all the way to the spinning ruby,
but when I press left or right I get an error:

My model does contain

class DirtyRuby < ShatteredModel::Base
key :pressed => :left, :action => { :translate => :left }
key :pressed => :right, :action => { :translate => :right }
end

Any ideas?

Yeah, the tutorials are quite out of date and what it looks like here is an artifact of trying to use old Shattered Ogre code with the new Ogre.rb backend.

Unless Mikkel and Martyn changed views on keybindings, that code should work, so I would mark that down as a bug. I currently don't have time to look into it myself, but I might be able to later.

Version 0.5.1 should address these issues. 

Let me know if it does,

I did the update on my computer here at work. Funny thing actually. My
"spinning ruby" was smaller than this @ symbol. maybe it's just this
computer though. As for the movment issue, still a no go.

Heh, I seriously thought I fixed this - ah well, another bug for trac.

You may want to regenerate the state(s).  The generated code has been cleaned up drastically.
After that, changing the position of the camera to be closer to the ruby should work:

From:
  camera :position => :z*300, :look_at => :zero
To:
  camera :position => :z*50, :look_at => :zero


also, to (temporarily) fix your error with the translate:

class DirtyRuby < ShatteredModel::Base
 key :pressed => :left, :action => { :move => :left }
 key :pressed => :right, :action => { :move => :right }

  def move(direction)
    translate(direction.to_v)
  end
end

Thanks for pointing out the error!

OMG! You rock! it worked. this stuff gives me a <%=
insert_favorite_noun_here %> .

So, now that I can get it to work, I want to know what it is i'm
doing. You said adding the method to the DirtyRuby model was a
temporary fix, so what does the .to_v method do exactly? Or I guess,
what does the "v" stand for, since I already know that it's converting
the object in a fashionable ruby manor :)

zero.to_v == Ogre::Vector3.new(0,0,0) == v(0,0,0)

Just different ways to display the same things.

It's a temporary fix, because translate(:left) should work fine.
