Syntax

USTRUCT (BlueprintType , Meta=(DisplayName="Mesh Selection"))  
struct FGeometryScriptMeshSelection

Remarks

FGeometryScriptMeshSelection is a container for a Mesh Selection used in Geometry Script. The actual selection representation is not exposed to BP, use functions in MeshSelectionFunctions/etc to manipulate the selection.

Internally the selection is stored as a SharedPtr to a FGeometrySelection, which stores a TSet (so unique add and remove are efficient, but the selection cannot be directly indexed without converting to an Array).

Note that the Selection storage is not a UProperty, and is not serialized. FGeometryScriptMeshSelection instances cannot be serialized, they are only transient data structures, that can be created and used Blueprint instances.

Functions

  Type Name Description
Public function void  
Public function void Combine SelectionB with current selection, updating current selection, using CombineMode to control how combining happens
Public function Static bool  
Public function Const EGeometryScriptIndexType Convert the current selection to a TArray, optionally converting to ConvertToType.
Public function Const void  
Public function Const int32 Note that for edge selections, this can return more elements than expected because both can be redundantly represented i.e. an edge can be in the selection once per 'half edge', since it is represented by triangle/index-in-triangle pair.
Public function Const int32 Return the number of valid, unique elements in the selection; e.g., with no double-counting of selected edges.
