Member Function Documentation

GetDynamicMeshElementsEmitter()

virtual void FGPUSpriteDynamicEmitterData::GetDynamicMeshElementsEmitter ( const FParticleSystemSceneProxy *  Proxy, const FSceneView *  View, const FSceneViewFamily &  ViewFamily, int32  ViewIndex, FMeshElementCollector &  Collector  ) const

inlineoverridevirtual

Reimplemented from FDynamicEmitterDataBase.

GetMacroUVOverride()

virtual const FMacroUVOverride & FGPUSpriteDynamicEmitterData::GetMacroUVOverride ( ) const

inlinevirtual

Returns the current macro uv override.

Reimplemented from FDynamicEmitterDataBase.

GetMaterialRenderProxy() [1/2]

const FMaterialRenderProxy * FGPUSpriteDynamicEmitterData::GetMaterialRenderProxy ( ) const

inline

Retrieves the material render proxy with which to render sprites. Const version of the virtual below, needed because GetDynamicMeshElementsemitter is const

GetMaterialRenderProxy() [2/2]

virtual const FMaterialRenderProxy * FGPUSpriteDynamicEmitterData::GetMaterialRenderProxy ( )

inlineoverridevirtual

Retrieve the material render proxy to use for rendering this emitter. PURE VIRTUAL

Parameters

bSelected

Whether the object is selected

Returns

FMaterialRenderProxy* The material proxt to render with.

Implements FDynamicEmitterDataBase.

GetSource()

virtual const FDynamicEmitterReplayDataBase & FGPUSpriteDynamicEmitterData::GetSource ( ) const

inlineoverridevirtual

Emitter replay data. A dummy value is returned as data is stored on the GPU.

Implements FDynamicEmitterDataBase.

ReleaseRenderThreadResources()

virtual void FGPUSpriteDynamicEmitterData::ReleaseRenderThreadResources ( const FParticleSystemSceneProxy *  InOwnerProxy )

inlineoverridevirtual

Called to release render thread resources.

Reimplemented from FDynamicEmitterDataBase.

RendersWithTranslucentMaterial()

bool FGPUSpriteDynamicEmitterData::RendersWithTranslucentMaterial ( ) const

inline

UpdateRenderThreadResourcesEmitter()

virtual void FGPUSpriteDynamicEmitterData::UpdateRenderThreadResourcesEmitter ( const FParticleSystemSceneProxy *  InOwnerProxy )

inlineoverridevirtual

Called to create render thread resources.

Reimplemented from FDynamicEmitterDataBase.
