?

The Drag space warp is a particle motion damper that reduces particle velocity by a specified amount within a specified range. The damping can be applied linearly, spherically, or cylindrically. Drag is useful for simulating wind resistance, transfers into dense media (like water), impacts with force fields, and other, similar situations.

With each damping type, you can control the damping effect along several vectors. The damping is also affected by particle system settings, such as speed.

**Properties:**

**'time
on'** Integer default: 0 --
integer; Time_On

The frame numbers at which the space warp becomes active and becomes inactive.

**'time
off'** Integer default: 16000
-- animatable; integer; Time_Off

The frame numbers at which the space warp becomes active and becomes inactive.

**symmetry**
Integer default: 0 --
radio button number; Damping_Symmetry

This group lets you choose Linear Damping, Spherical Damping, or Cylindrical Damping, plus a set of parameters for each.

**dampingx**
Float default: 5.0 --
animatable; percentage; X_Damping

Specifies the percentage of particle motion along the local Drag space warp axis that's affected by the damping.

**rangex**
Float default: 100.0
-- animatable; float; X_Range

Sets the thickness of the "range plane," or the infinite plane perpendicular to the specified axis. Takes effect only when Unlimited Range is turned off.

**falloffx**
Float default: 1000.0
-- animatable; float; X_Falloff

Specifies the distance beyond the X, Y, or Z Range within which Linear Damping is applied. Damping is strongest at the Range distance, decreases linearly out to the limit of the Falloff, and has no effect beyond that. While Falloff is effected only beyond the Range, it is measured from the center of the icon, and always has a minimum value equal to the Range value. Takes effect only when Unlimited Range is turned off.

**dampingy**
Float default: 0.0 --

Specifies the percentage of particle motion along the local Drag space warp axis that's affected by the damping.

**rangey**

**falloffy**
Float default: 1000.0
-- animatable; float; Y_Falloff

Specifies the distance beyond the X, Y, or Z Range within which Linear Damping is applied. Damping is strongest at the Range distance, decreases linearly out to the limit of the Falloff, and has no effect beyond that. While Falloff is effected only beyond the Range, it is measured from the center of the icon, and always has a minimum value equal to the Range value. Takes effect only when Unlimited Range is turned off.
