Cloth

The Cloth component provides a physics-based solution for the simulation of fabrics and works in conjunction with the Skinned Mesh Renderer. While it has been specifically designed for character clothing it is still possible to use arbitrary, non-skinned meshes.

属性

详细信息

布料不响应场景中的任何碰撞体，也不会将力反射回世界。添加 Cloth 组件后，该组件完全不会响应和影响任何其他实体。因此在手动将碰撞体从世界添加到 Cloth 组件之前，布料和世界无法识别或看到彼此。即使执行了此操作，模拟仍是单向的：布料可以响应实体，但不会反向施力。

此外，只能对布料使用三种类型的碰撞体：球体、胶囊体以及使用两个球形碰撞体构造而成的圆锥胶囊碰撞体。之所以存在这么多限制是为了帮助提高性能。

编辑约束工具

Selecting Edit Constraints will enter the editor into a mode to edit the constraints applied to each of the vertices in the cloth mesh. All vertices will be coloured based on the current Visualization mode to display the difference between their respective values.

There are two modes that can be used for changing the values for each vertex, in Select mode a group of vertices can be selected using the mouse cursor to either draw a selection box or else by individually clicking on vertices one at a time. Once any number of cloth vertices have been selected they can then have either Max Distance or Surface Penetration constraints enabled and a value assigned.

Paint mode allows you to directly adjust each individual vertex by clicking on it, again with options to adjust the Max Distance, Surface Penetration, or both. As before a value can be assigned and the visual representation in the scene view will be updated.

Collisions

布料无法直接与任意世界几何体碰撞，现在只会与胶囊碰撞体或球形碰撞体数组中指定的碰撞体相互作用。

球形碰撞体数组可以包含单个有效的 SphereCollider 实例（第二个为 null）或一对实例。在前一种情况下，ClothSphereColliderPair 仅表示待碰撞布料的单个球形碰撞体。在后一种情况下，它表示由两个球体以及连接这两个球体的锥体所定义的圆锥形胶囊形状。圆锥形胶囊形状在对角色的四肢进行建模时非常有用。
