A Physics Material 2D is used to adjust the friction and bounce that occurs between 2D physics objects when they collide. You can create a Physics Material 2D from the Assets menu (Assets > Create > Physics Material 2D ).
|Friction||Coefficient of friction for this collider.|
|Bounciness||The degree to which collisions rebound from the surface. A value of 0 indicates no bounce while a value of 1 indicates a perfect bounce with no loss of energy.|
To use a Physics Material 2D, simply drag it onto an object with a 2D collider attached or drag it to the collider component in the inspector. Note that for 3D physics, the equivalent asset is referred to as a Physic Material (ie, no S at the end of physic) - it is important in scripting not to get the two spellings confused.
