描述
|
|
----
|
|
|
|
3D 凸多面体形状，旨在用于物理。常用来为 :ref:`CollisionShape3D<class_CollisionShape3D>` 提供形状。
|
|
|
|
\ **ConvexPolygonShape3D** 是\ *实心*\ 的，与空心的 :ref:`ConcavePolygonShape3D<class_ConcavePolygonShape3D>` 不同，如果对象完全位于其内部，也能够检测到碰撞。因此更适于检测和物理。
|
|
|
|
\ **凸分解：**\ 凹多面体可以拆分为多个凸多面体。这样就能够让动态物理体拥有复杂的凹碰撞（以消耗性能为代价），做法是使用多个 **ConvexPolygonShape3D** 节点。要根据网格生成凸分解，请选中 :ref:`MeshInstance3D<class_MeshInstance3D>` 节点，前往出现在视口上方的 **Mesh** 菜单，然后选择\ **创建多个凸碰撞同级**\ 。或者也可以在脚本中调用 :ref:`MeshInstance3D.create_multiple_convex_collisions<class_MeshInstance3D_method_create_multiple_convex_collisions>`\ ，在运行时执行分解。
|
|
|
|
\ **性能：**\ **ConvexPolygonShape3D** 检查碰撞的速度比 :ref:`ConcavePolygonShape3D<class_ConcavePolygonShape3D>` 要快，但比 :ref:`SphereShape3D<class_SphereShape3D>`\ 、\ :ref:`BoxShape3D<class_BoxShape3D>` 等基本碰撞形状要慢。通常应该仅限于中等大小的对象，在无法使用基本形状精确表示碰撞时使用。
