Remarks

A widget that draws vertexes provided by a 2.5D StaticMesh. The Mesh's material is used. Hardware instancing is supported.

Variables

  Type Name Description
Protected variable TArray< FRenderData, TInlineAllocator< 3 > > RenderData  

Functions

  Type Name Description
Public function uint32

AddMesh ( USlateVectorArtData& InMeshData
)

 Draw the InStaticMesh when this widget paints.
Public function uint32

AddMeshWithInstancing ( USlateVectorArtData& InMeshData,
int32 InitialBufferSize
)

 Much like AddMesh, but also enables instancing support for this MeshId.
Public function void

AddRenderRun ( uint32 InMeshIndex,
uint32 InInstanceOffset,
uint32 InNumInstances
)

 Tell the widget to draw instances of a mesh a given number of times starting at a given offset.
Public function void

ClearRuns ( int32 NumRuns
)

 Discard any previous runs and reserve space for new render runs if needed.
Public function void

Construct ( const FArguments& Args
)

  
Public function UMaterialInstanceDynamic *

ConvertToMID ( uint32 MeshId
)

 Switch from static material to material instance dynamic.
Public function void

EnableInstancing ( uint32 MeshId,
int32 InitialSize
)

 Enable hardware instancing
Protected function Static void

PushUpdate ( uint32 VectorArtId,
SMeshWidget& Widget,
const FVector2D& Position,
float Scale,
uint32 BaseAddress
)

  
Protected function Static void

PushUpdate ( uint32 VectorArtId,
SMeshWidget& Widget,
const FVector2D& Position,
float Scale,
float OptionalFloat
)

  
Public function void

UpdatePerInstanceBuffer ( uint32 MeshId,
FSlateInstanceBufferData& Data
)

 Updates the per instance buffer. Automatically enables hardware instancing.
