Force fields offer a way to influence a simulation, in example to add extra movement. Particles, Soft Bodies, Rigid Bodies, and Cloth objects can all be affected by forces fields. Force fields automatically affect everything. To remove a simulation or particle system from their influence, simply turn down the influence of that type of force field in its Field Weights panel.
All types of objects and particles can generate fields, but only curve object can bear a 曲线引导 field.
Force fields can also be generated from particles. See Particle Physics.
您可以将粒子的影响限制在一组对象上(请参阅 粒子系统 页面).
To create a single force field, you can selectand select the desired force field. This method creates an empty with the force field attached.
要从现有对象创建一个字段，您必须选择该对象并切换到 物理 选项卡。在 力场 菜单中选择场类型。
更改场 场 面板或偏转 碰撞 面板设置后，您必须通过 释放缓存 重新计算软体或布料系统的粒子，这不是自动完成的。
Particles react to all kinds of force fields, soft bodies only to Force, Wind, Vortex (they react on Harmonic fields but not in a useful way).
Most fields have the same settings, even though they act very differently. Settings unique to a field type are described below. Curve Guide and Texture fields have very different options.
Sets the direction which is used to calculate the effector force. For force fields from an empty object only Point, Line 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.
The force only acts in the local XY plane, using the Z axis line as the effector.
The force only acts in the local Z direction, using the XY axis plane as the effector.
If nonzero, this adds a drag force proportional and opposite to the point velocity.
This effectively re-interprets the force field so that the Strength to Flow ratio at a certain point defines the velocity of an "air flow" field, and objects are encouraged to follow the flow by the resistance caused by the Flow drag force.
Influence the location of particles and other physics entities.
Influence the rotation of particles with Dynamic Rotation. The option is not relevant for other types of physics systems.
Disabling both options completely deactivates the force field.
Specifies how much the force is reduced when acting parallel to a surface, e.g. cloth. If set to 1, only the normal component of the force is taken into account.
脱落导致管状力场。场的径向衰减可以调整，以及场的 最小 和 最大 距离。
掉落会导致锥形的力场。附加选项与 管形 选项相同。
How the power of the force field changes with the distance from the force field. If r is the distance from the origin of the object, the force changes with 1/(r - min + 1)power. A falloff of 2 changes the force field with 1/(r - min + 1)2, which is similar to the falloff of gravitational pull.
The distance from the object's origin, up to where the force field is effective with full strength. If you have a falloff of 0, this parameter will have no effect, because the field is effective with full strength up to Max Distance (or infinite). Shown by an additional circle around the object.
Specifies the maximum radius in which the force field affects other objects (shown by an additional circle around the object).
