Collision object scales with object on x axis but not on y axis

Bugs
#1

I have an object with a sprite and a collision object, and I notice that when I put it a collection and set the object’s size, the collision object will scale along with the object’s x-axis scale, but not with the y axis scale. I also noticed that when I set the x scale to a small enough value, the collision object would change its size on the y axis even when no changes were made to it.

I googled it and it seems that similar issues have been encountered before, and from the looks of it, this is a bug, so I guess I’m gonna report this as one.

Any help is much appreciated, thanks.

#2

Neither Box2D nor Bullet3D support non uniform scaling. So it’s not a bug.

#3

So there’s no way to scale a collision object?

#4

Collision objects can be scaled; explained at the bottom of this page: Collision shapes

#5

If you scale the game object containing the collision object(s) uniformly (the same scale factor on all axes) it should work.

Make sure the Allow Dynamic Transforms is ticked.

#6

Scaling collision objects can be tricky. Have you tried enabling ‘Allow Dynamic Transforms’ or using uniform scaling for your game object? That might help with the issue.
