PhysicsShapeGroup2D.SetShapeVertex

Parameters

Description

Sets a single vertex of a shape.

NOTE: When accessing multiple vertices, it is more efficient to do one of the following:

• Get all the shape vertices using GetShapeVertices
• Get all the shape group vertices using GetShapeData
• Create the PhysicsShapeGroup2D with explicit shapes and vertices lists using the shape group Constructor
