Detailed Description

PrimitiveComponents are SceneComponents that contain or generate some sort of geometry, generally to be rendered or used as collision data.

There are several subclasses for the various types of geometry, but the most common by far are the ShapeComponents (Capsule, Sphere, Box), StaticMeshComponent, and SkeletalMeshComponent. ShapeComponents generate geometry that is used for collision detection but are not rendered, while StaticMeshComponents and SkeletalMeshComponents contain pre-built geometry that is rendered, but can also be used for collision detection.

Member Function Documentation

◆ BeginPlay()

void Karma::UPrimitiveComponent::BeginPlay ( )

overridevirtual

Used to detach physics objects before simulation begins. This is needed because at runtime we can't have simulated objects inside the attachment hierarchy.

Since: Karma 1.0.0

Reimplemented from Karma::UActorComponent.

◆ GetComponentTransformUniform()

std::shared_ptr< UniformBufferObject > Karma::UPrimitiveComponent::GetComponentTransformUniform ( ) const

inline

Getter for the transform uniform buffer object.

Returns: std::shared_ptr<UniformBufferObject> The uniform buffer object for the mesh's transformation matrix.

Since: Karma 1.0.0

◆ SetCachedMaxDrawDistance()

void Karma::UPrimitiveComponent::SetCachedMaxDrawDistance ( const float newCachedMaxDrawDistance )

Utility to cache the max draw distance based on cull distance volumes or the desired max draw distance.

Parameters

newCachedMaxDrawDistance The new max distance to be cached

Since: Karma 1.0.0

◆ SetWorldTransform()

void Karma::UPrimitiveComponent::SetWorldTransform ( const FTransform & NewTransform )

overridevirtual

Set the transform of the component in world space.

Parameters

NewTransform New transform in world space for the component.

Rest are physics related. To be implemented in future.

Parameters

SweepHitResult	Hit result from any impact if sweep is true.
bSweep	Whether we sweep to the destination location, triggering overlaps along the way and stopping short of the target if blocked by something. Only the root component is swept and checked for blocking collision, child components move without sweeping. If collision is off, this has no effect.
bTeleport	Whether we teleport the physics state (if physics collision is enabled for this object). If true, physics velocity for this object is unchanged (so ragdoll parts are not affected by change in location). If false, physics velocity is updated based on the change in position (affecting ragdoll parts). If CCD is on and not teleporting, this will affect objects along the entire sweep volume.

Since: Karma 1.0.0

Reimplemented from Karma::USceneComponent.
