Syntax
class UChaosPhysicalMaterial : public UObject
Remarks
Physical materials are used to define the response of a physical object when interacting dynamically with the world.
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
float | AngularEtherDrag | Uniform angular ether drag, the resistance a body experiences to its rotation. |
 |
float | Friction | Surface properties.Friction value of a surface in motion, controls how easily things can slide on this surface (0 is frictionless, higher values increase the amount of friction) |
 |
float | LinearEtherDrag | Uniform linear ether drag, the resistance a body experiences to its translation. |
 |
float | Restitution | Restitution or 'bounciness' of this surface, between 0 (no bounce) and 1 (outgoing velocity is same as incoming). |
 |
float | SleepingAngularVelocityThreshold | How much to scale the damage threshold by on any destructible we are applied to |
 |
float | SleepingLinearVelocityThreshold | How much to scale the damage threshold by on any destructible we are applied to |
 |
float | StaticFriction | Friction value of surface at rest, controls how easily things can slide on this surface (0 is frictionless, higher values increase the amount of friction) |
