public void SetShapeAdjacentVertices(int shapeIndex, bool useAdjacentStart, bool useAdjacentEnd, Vector2 adjacentStart, Vector2 adjacentEnd)

Parameters

shapeIndex

int
The index of the shape to be modified that is stored the PhysicsShapeGroup2D.

useAdjacentStart

bool
Sets the _useAdjacentStart property of the selected shape.

useAdjacentEnd

bool
Sets the _useAdjacentEnd property of the selected shape.

adjacentStart

Vector2
Sets the _adjacentStart property of the selected shape.

adjacentEnd

Vector2
Sets the _adjacentEnd property of the selected shape.

Remarks

NOTE: Calling this on a PhysicsShape2D that does not have a shapeType of PhysicsShapeType2D.Edges will result in an exception being thrown.
