Detailed Description

A mesh group which is a collection of meshes and their related FISMPoolMeshInfo. We group these with a single handle with the expectation that a client will want to own multiple meshs and release them together.

Member Function Documentation

AddMesh()

FISMPoolMeshGroup::FMeshId FISMPoolMeshGroup::AddMesh	(	const FISMPoolStaticMeshInstance &	MeshInstance,
		int32	InstanceCount,
		const FISMPoolMeshInfo &	ISMInstanceInfo,
		TArrayView< const float >	CustomDataFloats
	)

Adds a new mesh with instance count. We expect to only add a unique mesh instance once to each group. Returns a ID that can be used to update the instances.

BatchUpdateInstanceCustomData()

void FISMPoolMeshGroup::BatchUpdateInstanceCustomData	(	FISMPool &	ISMPool,
		int32	CustomFloatIndex,
		float	CustomFloatValue
	)

BatchUpdateInstancesTransforms()

bool FISMPoolMeshGroup::BatchUpdateInstancesTransforms	(	FISMPool &	ISMPool,
		FMeshId	MeshId,
		int32	StartInstanceIndex,
		TArrayView< const FTransform >	NewInstancesTransforms,
		bool	bWorldSpace,
		bool	bMarkRenderStateDirty,
		bool	bTeleport
	)

Update instance transforms for a group of instances.

RemoveAllMeshes()

void FISMPoolMeshGroup::RemoveAllMeshes

(

FISMPool &

ISMPool

)

Remove all of our managed meshes and associated instances.

Member Data Documentation

bAllowPerInstanceRemoval

bool FISMPoolMeshGroup::bAllowPerInstanceRemoval = false

Flag for whether we allow removal of instances when transform scale is set to zero.

MeshInfos

TArray<FISMPoolMeshInfo> FISMPoolMeshGroup::MeshInfos

Array of allocated mesh infos.
