How to make things slide like on ice?

[Hoboken Pudding]

I'm trying to understand how to make the Player move across and not stop until they hit a wall. I'm doing a new version of this marble maze but I want the player to roll down the corridor, not move step-by-step. https://hobokenpudding.itch.io/lil-red-marble

I've takena look at the code for a few ice games but am not clear what is being set up. Do you need to create four instances of the player "PlayerU, PlayerD, PlayerR, PlayerL"? I assume "again" is used but not sure how. Any help or point to examples would be appreciated.

maybe something like

[target wall]->[]

[ player ice | target | ] -> [ >player ice | | target ] again

[ > player ice | | ] -> [ > player ice | | target ] again

Thanks. This helped, but got weird.

I've been able to get the player to move across to the first instance of a wall or crate, but it's a jump, not a slide.
See here: http://www.puzzlescript.net/play.html?p=d9391c4340e6753ee166c37abf376acc

I'm using the following:

[ > player | no Item ] -> [ | > player ] again
[ > player | Wall ] -> [ player | Wall ]

I'm not sure how to get it to slide across, space by space, rather than jump.

You need an object that will keep track of which way the marble is travelling.  Let's call it Cursor.

========

OBJECTS

========

...

Cursor

Transparent

It should be in its own layer.  I use the top layer so I can easily give it a sprite to watch it when debugging.

================

COLLISIONLAYERS

================

...

Cursor

And you want to place this Cursor a couple of squares in front of your moving Player so it can chase it.  These three rules:

1. If the Player is next to a Cursor, move the player towards the Cursor and remove the Cursor.
2. If the Player is moving, caused by control or by rule 1, place a Cursor a couple of squares ahead and trigger another turn.
3. If the Cursor is on an Item, remove the Cursor so the Player stops chasing it after this turn.

======

RULES

======

...

[ Player | Cursor ] -> [ > Player | ]

[ > Player | no Item | ] -> [ > Player | | Cursor ] again

[ Cursor Item ] -> [ Item ]

Also, I think you don't want your Target to be an Item.  It's part of the floor, not an obstruction for the player.

On another note, I like your game!  I look forward to seeing more puzzles.

I had a thought for a couple of features when you feel more confident.  Currently you can only push a crate if your adjacent to it.  How about a heavy crate that you can only push with a run up, and a light crate that you can push adjacently or with a run up (whether you like it or not.)

Thanks for all the feedback. I had thought of making the crates that would move with a run up but I also like your ideas for different weights. I'll see what I can do!

[Hoboken Pudding]

This works great and does exactly what I was looking to do. I'll post an update once I get some more puzzles in there.

How would you make a crate, that when pushed, it would slide until it hit a wall?

[That Scar]

Here are some things I quickly came up with but didn't test so do come back here if they don't work and you can't figure out how to make them work:

If you don't care about crates "teleporting instead of moving", here is a quick hack:

[ > Crate | Ice No Crate No Wall ] -> [ | > Crate Ice ]

If you do care about that teleport bit or if you don't want the "if there's no crate in front of me" clause because you want crates to push other things, I suggest creating 4 invisible objects that just say "continue left", "continue up" and so forth.

Up [ ContinueUp | Crate Ice ] -> [ | > Crate Ice ]

Left [ ContinueLeft | Crate Ice ] -> [ | > Crate Ice ]

Right [ ContinueRight | Crate Ice ] -> [ | > Crate Ice ]

Down [ ContinueDown | Crate Ice ] -> [ | > Crate Ice ]

[ ContinueUp ] -> [ ]

[ ContinueLeft ] -> [ ]

[ ContinueRight ] -> [ ]

[ ContinueDown ] -> [ ]

I think you should do the other code inside here and after you're done, finish with these lines:

[ up Crate ] -> [ up Crate ContinueUp ] again

[ left Crate ] -> [ left Crate ContinueLeft ] again

[ right Crate ] -> [ right Crate ContinueRight ] again

[ down Crate ] -> [ down Crate ContinueDown ] again

The `again` tag will tell it to continue doing all the code again and again until it all boxes have stopped from moving and a huge plus of this method is that you can actually see the boxes moving in action instead of zooming straight to the end of the ice line, yay! (again, I didn't test this code)
