Member Function Documentation

Advance()

void FAnimTrailParticleRenderData::Advance ( )

inline

Move the pointers along the trail.

CalcVertexData()

void FAnimTrailParticleRenderData::CalcVertexData ( float  InterpFactor, FVector &  OutLocation, FVector &  OutFirst, FVector &  OutSecond, float &  OutTileU, float &  OutSize, FLinearColor &  OutColor, FVector4f *  OutDynamicParameters  )

inline

inline

GetNext()

void FAnimTrailParticleRenderData::GetNext ( )

inline

Inits the next particle from the current Particle.

Init()

void FAnimTrailParticleRenderData::Init ( )

inline

Initializes the state for traversing the trail and generating vertex data.
