Type	Description
bool

DrawFlags

Gets or sets the debug draw flags.

Declaration

PhysicComponentList

Gets the physics component list.

Declaration

public IEnumerable<Behavior> PhysicComponentList { get; }

Property Value

IEnumerable<Behavior>

PhysicWorldResolution

Gets or sets the resolution of the physics world. Changing this value does not affect the size or positions of Evergine entities. It only affects the internal physics world. By default, the resolution of the world is 1. This means that 1 unit in Evergine is equal to 1 unit in the physics world. Changing it to 10 indicates that 1 unit in Evergine is equivalent to 10 units in the physics world. We recommend increasing this value up to 10 if your physics bodies usually have sizes of centimeters.

Declaration

public abstract float PhysicWorldResolution { get; set; }

Property Value

Type	Description
float
