part_type_life(ind, life_min, life_max);
| 参数 | 描述 |
|---|---|
| ind | The index of the particle type to change. |
| life_min | The minimum lifespan of the particles. |
| life_max | The maximum lifespan of the particles. |
返回： N/A（无返回值）
This is the function that governs how long each individual
particle of the indicated type remains on the screen. As with other
particle functions, you provide a minimum and a maximum value (in
steps)and each particle lifespan will be a random number of steps
from within the specified range. To have all particles with the
same lifetime, set the two values to be the same.
part_type_life(part_Flare, room_speed, room_speed * 2);
The above code will set all particles created of the particle type indexed in the variable "part_Flare" to have a lifetime of between 1 and 2 seconds, based on the current room-speed.
