Particle Flow - Quick Navigation

Description:

The Speed operator provides basic controls over particle speed and direction.

Constructor:

Speed... 

Properties:

<Speed>.Speed Float default:300.0 --world units 

Get/set the particle speed in system units per second.

<Speed>.Variation Float default:0.0 --world units 

Get/set the amount by which particle speed can vary, in system units per second.

<Speed>.Direction Integer default:0 

0: Along Icon Arrow - Particles move parallel to the icon arrow. Rotate the icon to change the direction.

1: Icon Center Out - Each particle moves along an imaginary line drawn between the particle's location and the icon center.

2: Icon Arrow Out - Each particle moves along an imaginary line drawn between the particle's location and the icon arrow. The line is perpendicular to the icon arrow, which is considered an infinite line for this purpose.

3: Random 3D - Particles move in all directions. This option is affected by the .Random_Seed setting.

4: Random Horizontal - Each particle moves in a random horizontal direction; that is, parallel to the world XY plane. This option is affected by the Random_Seed value.

5: Inherit Previous - Uses the current direction of motion.

<Speed>.Reverse Boolean default:false 

When set to True, the direction is reversed.

<Speed>.Divergence Float default:0.0 

When set to True, spreads out the particle stream. Use the numeric setting to define the extent of the divergence, in degrees. Range is from 0 to 180. The value is animatable.

<Speed>.Random_Seed Integer default:12345 

Specifies a randomization value.
