Gameboy Development Forum

Hi, first post here. I made this account because I've been stuck on making a game mechanic for a GB studio game jam and I figured this is the right place to ask.

I've shaved down the sample project to only contain the top-down code. I'm trying to make a puzzle game where the player has a magnet gun that attracts/repels crates based on their charge.

Essentially, A will emit a positive charge and B will emit a negative charge. when the button is pressed, the nearest crate that the player is facing will be attracted/repelled 1 tile. I've been trying to repurpose furniture pushing/pulling code but it's just not working. Any pointers?
