part_type_alpha3(ind, alpha1, alpha2, alpha3);
|ind||The index of the particle type to change.|
|alpha1||The starting alpha of the particle.|
|alpha2||The halfway point alpha of the particle.|
|alpha3||The ending alpha of the particle.|
This function can be used to set a three alpha (transparency)
value gradient for each particle created of the given type. The
first alpha is that which all particles will start with, and the
second alpha is the one that will be blended to half way through
its lifetime and the third alpha is the one with which the particle
will end with. A smooth gradient change will occur through the
alphas over the particles lifetime from one to the other.
part_type_alpha3( part_Health, 0.5, 1, 0);
The above code will make all particles created of the type indexed in the variable "part_Health" have an alpha blend from 0.5 to 1 to 0 over their lifetime.
