|Values:||Integers, from 0 to 7|
Defines the direction of the simulated wind system. The flag accepts values from 0 to 7, where each number represents a point of the compass. 0 is for North, and increasing numbers rotate clockwise on the compass.The wind causes gas particle systems move into the direction defined in WindDirection. However, it is disabled by default in each particle system. To enable it, change the value of the -flag to anything between 1-5 (0 is no effect). Increasing numbers cause the wind to have stronger effect on the corresponding particles.
