PhysicsShapeGroup2D.SetShapeVertex

파라미터

설명

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 Additional resources: GetShapeVertex.
