part_type_direction - hpgDesigns/hpgdesigns-dev.io GitHub Wiki
Sets the direction properties for the given particle type. Particles will be created with a randomly generated direction between the minimum and maximum thresholds (which must be in counter-clockwise degrees) and will turn left or right each step depending on the relative direction change you specify.
| Parameter | Data Type | Description |
|---|---|---|
| ind | integer | index of the particle type |
| min | double | minimum direction in counter-clockwise degrees, default is 0 |
| max | double | maximum direction in counter-clockwise degrees, default is 0 |
| incr | double | relative direction change each step, default is 0 |
| wiggle | double | wiggling of the direction, default is 0 |
void: This function does not return anything.
