2D 物理材质 (Physics Material 2D) 用于调整 2D 物理对象碰撞时这些对象之间的摩擦和弹性。可通过 Assets 菜单 (Assets > Create > Physics Material 2D) 创建 2D 物理材质。
属性: | 功能: |
---|---|
Friction | 此碰撞体的摩擦系数。 |
Bounciness | 碰撞从表面反弹的程度。值为 0 表示没有弹性,而值为 1 表示完美弹性,没有能量损失。 |
要使用 2D 物理材质,只需将其拖动到已附加 2D 碰撞体的对象上,或将其拖动到 Inspector 中的碰撞体组件。请注意,在 3D 物理中,等效资源称为 Physic Material(物理材质)_(即 physic_ 末尾没有 S)。在脚本中不要混淆这两种拼写,这很重要。
