Edge Collider 2D

The Edge Collider 2D component is a Collider for use with 2D physics. The Collider’s shape is defined by a freeform edge made of line segments, so you can adjust it to fit the shape of the Sprite graphic with great precision. Note that this Collider’s edge need not completely enclose an area (unlike the similar Polygon Collider 2D), and for example can be a straight line or an L-shape.

To edit the polyline directly, hold down the Shift key while you move the mouse over an edge or vertex in the Scene view. To move an existing vertex, hold down the Shift key and drag that vertex. To create a new vertex, hold down the Shift key and click where you want the vertex to be created. To remove a vertex, hold down the Ctrl (Windows) or Cmd (macOS) key and click on it.

To hide the outline of the 2D move Gizmo while editing the Collider, click the fold-out arrow on the Sprite Renderer component in the Inspector to collapse it.
