GameObject keeps bouncing after hitting a bouncy material
I got a Edge collider as the ground and some square shaped sprites with RigidBody2D and BoxCollider2D components. I've added a physics2D material to the ground with below properties to make the sprites bounce a little after hitting the ground.
Friction: 1
Bounciness: 0.2
When I run the game, sprites fall off and hit the ground with a little bouncing. But the never fully stop after hitting the ground and keep bouncing very slightly like their vibrating.
How can I make the sprites fully stop after 2 or 3 times hitting the ground by bouncing?
Such effects are usually minimized if your object has some drag. Drag will permanently slow down your object and should prevent endless bouncing.
Sound pretty obvious right know but I was close to drive myself crazy for that little thing! Thanks!
You could also check the bouncing threshold (don't know what it is called exactly) in the global physics settings. There is a minimum bouncing below which objects stop bouncing at all.
The "Bounce Threshold" is a Physics3d setting so has no influence here (Physics2d). In the 2d settings there's a similar setting called "Velocity Threshold" which is usually set to "1". So every collision that happens at a speed less than that threshold is treated as inelastic and won't bounce
So thanx to @MelvMay I turned down the gravity of the sprites a little (from 8 to 2), and the viration is now gone after a few bouncings.
Sounds like you might have the global gravity turned-up high and/or the Rigidbody2D gravity-scale turned-up. You might also want to turn the friction down a little to see if that helps.
