part_type_speed - hpgDesigns/hpgdesigns-dev.io GitHub Wiki
Sets the speed properties for the given particle type. Particles will be created with a randomly generated speed between the minimum and maximum thresholds and will slow down or speed up each step depending on the relative speed change you specify. The speed of particles is never negative, so particles will slow down until they completely stop.
| Parameter | Data Type | Description |
|---|---|---|
| ind | integer | index of the particle type |
| min | double | minimum speed, default is 0 |
| max | double | maximum speed, default is 0 |
| incr | double | relative speed change each step, default is 0 |
| wiggle | double | wiggling of the speed, default is 0 |
void: This function does not return anything.
