Syntax
class UPhysicalMaterial : 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 | |
|---|---|---|---|
 |
bool | bOverrideFrictionCombineMode | If set we will use the FrictionCombineMode of this material, instead of the FrictionCombineMode found in the project settings. |
 |
bool | bOverrideRestitutionCombineMode | If set we will use the RestitutionCombineMode of this material, instead of the RestitutionCombineMode found in the project settings. |
 |
float | Density | Object properties.Used with the shape of the object to calculate its mass properties. |
 |
float | Friction | Surface properties.Friction value of surface, controls how easily things can slide on this surface (0 is frictionless, higher values increase the amount of friction) |
 |
TEnumAsByte< EFrictionCombineMode::Type > | FrictionCombineMode | Friction combine mode, controls how friction is computed for multiple materials. |
 |
TUniquePtr< FPhysicsMaterialHandle > | MaterialHandle | |
 |
float | RaiseMassToPower | Used to adjust the way that mass increases as objects get larger. |
 |
float | Restitution | Restitution or 'bounciness' of this surface, between 0 (no bounce) and 1 (outgoing velocity is same as incoming). |
 |
TEnumAsByte< EFrictionCombineMode::Type > | RestitutionCombineMode | Restitution combine mode, controls how restitution is computed for multiple materials. |
 |
float | SleepAngularVelocityThreshold | How low the angular velocity can be before solver puts body to sleep. |
 |
int32 | SleepCounterThreshold | How many ticks we can be under thresholds for before solver puts body to sleep. |
 |
float | SleepLinearVelocityThreshold | How low the linear velocity can be before solver puts body to sleep. |
 |
float | StaticFriction | Static Friction value of surface, controls how easily things can slide on this surface (0 is frictionless, higher values increase the amount of friction) |
