Edge Collider 2D

The Edge Collider 2D component is a Collider you can use with 2D physics. The Collider’s shape is a freeform edge made of line segments that you can adjust to fit the shape of a Sprite graphic or other shape. The Collider’s start and end points do not need to meet and completely enclose an area (unlike the Polygon Collider 2D), and can form a straight line or other single edge shape.

属性 功能
Edit Collider Select the Edit Polyline button (polyline icon) to make the collider outline editable. See the Collider Shortcuts below for the shortcuts available when Edit Collider is enabled.
Material Select the Physics Material 2D for this Collider to determine how it interacts with other Colliders.
Is Trigger Enable this property to make the Collider behave as a trigger.
Used by Effector Enable this property to make an attached Effector 2D component use this Collider.
Offset X/Y Set the x/y amounts to offset the Collider geometry.
Edge Radius Set a value that forms a radius around the edge of the Collider. This results in a larger Collider 2D with rounded convex corners. The default value is 0 (no radius).
Points 有关生成碰撞体的复杂性的不可编辑信息。
    Use Adjacent Start Point Enable this property to calculate the collision response using the Adjacent Start Point to form the collision normal when a collision occurs at the Edge Collider’s start point.
    Adjacent Start Point X/Y Set the x/y-coordinates of the Adjacent Start Point.
    Use Adjacent End Point Enable this property to calculate the collision response using the Adjacent End Point to form the collision normal when a collision occurs at the Edge Collider’s end point.
    Adjacent End Point X/Y Set the x/y-coordinates of the Adjacent End Point.

Collider Shortcuts (when Edit Collider is enabled)

Shortcut 功能
Hold and drag vertex or edge. Move the selected vertex and edge to a different position.
Click anywhere along an edge. Create a new vertex by clicking an empty space along the edge.
Hold the Ctrl (Windows) or Command (macOS) key and select a vertex or edge. Deletes the selected vertex or edge.
