# 简介¶

• 所有类型的物体和粒子都可以生成力场，但只有曲线物体可以承受 曲线指令 力场。
• 力场也可以从粒子生成。 请参阅 粒子物理
• 对象需要共享至少一个公共层才能生效。

## 创建力场¶

 Vortex force field. 风力场 Force force field.

Note

## 常用力场的设置¶

Sets the direction which is used to calculate the effector force. For force fields from an empty object only Point and Plane shapes are available, as for a field from a 3D object there are additional Surface and Every Point options, and Curve for a field from a curve.

Influence only in the local Z direction.
The force field acts on a 3D object's surface. In this case, the Z axis is the surface normal.

Uses every vertex in the mesh object as an effector point.
Curve
The force field acts along a curve object.

If non-zero, the effective force depends on the particle velocity. The value defines how quickly the effector force (acceleration) will be converted into the constant "air flow" velocity.
