Hockey puck gets "sucked" to corners

[henymeny]

I’m using a scaled cylinder for the hockey puck which has a capsule collider, but I assume it’s fine because I ignore movements over Y axis.

In the video I’ve created a physics material with bounciness 1 and friction 0, the puck has mass 1 and drag 0.2, but once the puck is slow instead of bouncing it gets sucked to the corners:

I’ve tried playing with all these settings, friction, drag, mass, collision detection & interpolation and others but can’t seem to find the problem. Could it be the capsule collider? or is this some physics engine quirk I’m not aware?

Any ideas appreciated.

check if this fixes it

2D physics and balls within rectangular borders

Box2D has a velocity threshold (in 2D physics settings) which I converted from a compile-time constant to something you can change at runtime. Any collisions with a relative linear velocity below this threshold will be treated as inelastic.

Most hockey rinks doesn’t have sharp corners.

perfect, exactly what I needed. I hadn’t realized this setting exists: project settings → physics → bounce threshold. changed from 2 to 0.02 and it works perfectly.

thanks. but it’s not really hockey, it’s lesser-known sling-puck
