2D 物理材质
切换到脚本2D 物理材质 用于调整 2D 物体在碰撞时产生的摩擦和弹跳。
有关游戏物理的更多详细信息，请参阅 3D 物理学。
使用 2D 物理材质
要创建 2D 物理材质，请转到 资产 > 创建 > 2D > 2D 物理材质。
| 属性 | 功能 |
|---|---|
| 摩擦 | 设置此 碰撞体用于处理物理碰撞的可见形状。碰撞体不需要与对象的网格形状完全相同 - 常常更有效的粗略近似在游戏中不受识别。更多信息 在 词汇表 中查看 的摩擦系数。 |
| 弹性 | 设置碰撞从表面反弹的程度。值为 0 表示无反弹，值为 1 表示完美反弹且无能量损失。 |
要使用您创建的 2D 物理材质，请将其拖到具有附加 2D 碰撞体组件的对象上，或将其拖到 检查器一个 Unity 窗口，显示有关当前选择的 GameObject、资产或项目设置的详细信息，允许您检查和编辑值。更多信息
在 词汇表 中查看 窗口中的碰撞体上。
注意：3D 物理学中的等效资产 refers to as a 物理材质用于调整碰撞物体摩擦和弹跳效果的物理资产。更多信息
