# 碰撞

• 可以限制粒子的影响至一组物体(在 力场权重面板).

• 软体物体 偏移 比较困难，它们经常穿透碰撞物体。

• 毛发粒子忽略偏移物体(但您可以将它们作为软体进行动画化，软体会计算偏移)。

A collider object can be temporarily disabled via an animatable toggle to the right of the button that permanently activates or deactivates it.

## 选项

### 软体和布料

Note

• 0.0 - 无阻尼，软体弹性最大。

• 1.0 - 最大阻尼，软体不会弹开。

When enabled, the collider is considered to represent the boundary of a solid object rather than a thin surface, and ejects intersecting cloth in the direction of its normal.

Note

## 示例

Here is a Meta object, using Instancing Vertices to a particle system emitting downwards, and deflected by a mesh cube.

## 提示

• Make sure that the normals of the mesh surface are facing towards the particles/points for correct deflection. Negative scales on the object can have a similar effect. Make sure to recalculate the normals after applying the scale.

• 毛发粒子直接受力场影响，所以如果你使用一个短距离的力场，不一定需要碰撞。

• 粒子编辑模式 中，毛发粒子会忽略其生成的网格。但你至少可以用碰撞塑造毛发。
