Question
I’m trying to make a puzzle game that involves moving boxes and precise and trustworthy interaction between them. (I want them to act the same each time the interaction happens)
My problem is that after restarting the level, for some reason the physics change (even if I reposition everything on the exact spot they spawned the first time)
This happens randomly and with seemingly no reason at all, sometimes the blocks get into the place they need fast, and sometimes they take ages.
This is what’s happening, look at the crate on the right the first run and the second run (hovering only makes the sprite bigger)
In case it could help understand the situation, I’ll link both the scene explanation and the full code of the crate.
block_spawner never moves, and it’s a node that I just use to move the box back to its position each time the game startsSprite2D and CollisionShape2D do exactly what their name says.I use
fallTimer and hitSfx to make a sound when the block has been falling for too long.Material menu is a button that I just use to send a signal on hover to make the sprite bigger.hoverSfx is a sound that plays on hover, and timeOnGround is used to decide when to start rotating the block to free it from being stuck, however I don’t think it works like it’s supposed to (duration is 0.5s)

I have no idea in why this happens, any help is appreciated.
TLDR: blocks get unstuck fast the first time i play a level, get unstuck slow the second time i play and it goes randomly after that
Thanks in advance
