How to directly stop 2 pieces moving when they collide?

Unity Engine
1

Hello,

I’m making a puzzle sliding game and now I’d like to make a piece stop moving when it hits another piece. Now, when i set all the rigidbodys to FreezeAll, there is no collision anymore, pieces go through each other as if they are not there. Is this a bug, or am I doing something wrong?

What I’d like to achieve is to make 2 pieces directly stop moving when they collide. Is this the right way or should I do someting else?

Thanks

You can set the velocity to 0,0,0 and stop it in its tracks.

Thanks,

but this might only work right after a collision. What i;d like to do is make an immovable object. Like a constant force to a wall and the wall won’t move. I thought FreezeAll would work?

So that when you slide a piece of the puzzle, that it will stop when colliding with another piece, while you are still trying to drag the piece throught the other piece.

have you thought of creating a set of points for the pieces to lerp to so they always stay square to the other pieces? Almost like a grid. I came across a one liner not long ago that locks the transforms in a grid, so if you slide it or move it however it stays within the set units apart.

Thanks, I’m porting this game to Unity and this is how i did do it before, but then you have to keep track of the positions of the pieces, I thought it should be easier done in Unity. But why doesn’t FreezeAll work? When freezing rotation and position one by one it stops moving or rotating in those directions after a collision, but when you turn on all the constraints, then there is no more collision. I was wondering if this is a bug?
