__2D 边界碰撞体__组件是用于 2D 物理的碰撞体。碰撞体的形状由线段组成的自由形状边缘定义,因此可对其进行高精度调整以适应精灵图形的形状。请注意,此碰撞体的边缘无需完全包围一个区域(与类似的 2D 多边形碰撞体 (Polygon Collider 2D) 不同),比如可以是直线或 L 形。
属性 | 功能 | |
---|---|---|
Material | 一种物理材质,可用于确定碰撞的属性(例如摩擦和弹性)。 | |
Is Trigger | 如果希望此碰撞体作为触发器运行,请勾选此框。 | |
Used by Effector | 附加的效应器是否使用该碰撞体。 | |
Offset | 碰撞体几何形状的局部偏移。 | |
Edge Radius | 控制边缘周围的半径,使顶点为圆形。这会产生一个具有圆凸角的更大 2D 碰撞体。此设置的默认值是 0__(无半径)。| |Points__ | 有关生成碰撞体的复杂性的不可编辑信息。 |
要直接编辑折线,请按住 Shift 键的同时在 Scene 视图中将鼠标移到边缘或顶点上。要移动现有顶点,请按住 Shift 键并拖动该顶点。要创建新顶点,请按住 Shift 键并单击要创建顶点的位置。要删除顶点,请按住 Ctrl (Windows) 或 Cmd (macOS) 键并单击该顶点。
要在编辑碰撞体时隐藏 2D 移动辅助图标的轮廓,请单击 Inspector 中的精灵渲染器 (Sprite Renderer) 组件上的折叠箭头,从而折叠该组件。
