public int AddEdges (List<Vector2> vertices, float edgeRadius= 0f);

파라미터

vertices A list of vertices that represent a continuous set of edges with each vertex connecting to the following vertex to form each edge.
edgeRadius The radius extending around each edge. This is identical to EdgeCollider2D.edgeRadius.

int Returns the shape index the shape was added to in the PhysicsShapeGroup2D. This index is used as the main reference when retrieving a shape.

설명

Adds an edges shape (PhysicsShapeType2D.Edges) to the shape group.

An edge shape is comprised of multiple edges (line segments) defined by all the specified vertices and an edgeRadius that extends around the all the edge(s).

NOTE: Edges do not form closed a shape as they do not have any interior even if the first and last vertex were to overlap therefore the logical interior is not detectable by physics queries etc.

edgeRadius The radius extending around each edge. This is identical to EdgeCollider2D.edgeRadius.
useAdjacentStart When the value is true, the adjacentStart argument is used. When the value is false, the adjacentStart argument is not used.
useAdjacentEnd When the value is true, the adjacentEnd argument is used. When the value is false, the adjacentEnd argument is not used.
adjacentStart Defines the position of a virtual point adjacent to the start vertex of an edge shape.
adjacentEnd Defines the position of a virtual point adjacent to the end vertex of an edge shape.
