Physics material which represents a set of physical surface properties.

Type declaration

Name	Type	Description
staticFriction	Float	The friction coefficient applied between this surface and another surface if they are not moving lateral to each other. Usually a value from 0 to 1. A value of zero feels like ice, a value of 1 will make it very hard to get the object moving. Resulting static friction of a physics body colliding with another is determined by the average of both bodies' static friction coefficient.
dynamicFriction	Float	The friction coefficient applied between this surface and another surface if they are moving relative to each other. Usually a value from 0 to 1. A value of zero feels like ice, a value of 1 will make it very hard to get the object moving. If set to greater than staticFriction, the effective value of staticFriction will be increased to match. Resulting dynamic friction of a physics body colliding with another is determined by the average of both bodies' dynamic friction coefficient.
restitution	Float	Restitution coefficient, or bounciness of surface. A coefficient of 0 indicates as little bounce as possible, higher values up to 1.0 result in more bounce. Should be in the range [0,1]. Resulting bounciness of a physics body colliding with another is determined by the average of both bodies' restitution.
contactVelocity	Vec3	The velocity applied to the contact between this physics body and another body. Only applies if modifyContact is true.
modifyContact	boolean	Whether to modify the contact when this physics body collides with another body.
isTrigger	boolean	Whether to consider the geometry associated to this physics material as a trigger or not.
