Actually it's playable in: https://play.threadbare.game/branches/endlessm/wjt/in-game-push-blocks-prototype/#res://in_game_sokoban_test.tscn

@wjt @JoniCeceri I see two options here:

1. The boxes could be pushed without any grid constraint (like in this prototype or in MINIT).
2. Or, the boxes could be pushed in a grid (with an AnimatableBody2D node maybe?) while the player move towards the box or use the "repel" action on them.

I think both have potential, it all depends on the kind of puzzles we want. Maybe 2 can open up more possibilities for pattern-based puzzles? Check this level for StoryQuest "Gazzart" that does the latter: https://game-lab-5-0-utp-group-6-team-3.github.io/threadbare/#quests/story_quests/gazzart/2_game_castle/gazzart_castle

@med-bc and team, if you can help us understand how you did the boxes puzzles, that would be great!

@wjt you made it work! Nice!

I have tried several different ways to move the blocks in response to the repel action:

• Keep the blocks as a CharacterBody2D, set velocity in the closest cardinal direction of the repel; decelerate at a constant rate, with the two constants chosen (with some dodgy maths) to move the block almost exactly 64px in that direction.
• Make the blocks be a RigidBody2D. What I couldn't make work here is that we want the player pushing against the body to never move it (as if it's a wall); but I couldn't make that work.

The other problem with the "repel" action is that these puzzles rely on exact control of the blocks, but the repel circle is wide enough that it's hard to avoid repelling two blocks at once if they are close together. I don't think it's going to work.

The third thing to try is hitting it with the sword, which would be most easily prototyped by making it hookable I guess but with negative weight?
