Hi Julian, here's how I'd do it:
1) Create a new float User Parameter on your PType and call it
"/alphaLimit/".
2) Create a pEvent called "BIRTH" (Particle Age % 0, Per Trigger
Particle, Jscript)
// Just point to an up-level parameter if you want to animate this
value over time.
inParticle.Attributes("alphaLimit").Value = 100;
3) Create a pEvent called "RUNTIME" (Every 1 Frame, Per Particle,
Jscript)
var alpha;
var age = inParticle.age;
var alphaLimit = inParticle.Attributes("alphaLimit").Value;
var color = inParticle.color;
// This is the simpliest way to script it, although it's a ll linear.
alpha = 1 - (age / alphaLimit);
color.alpha = alpha;
inParticle.color = color;
Is that what you're looking for?
Hi Vince,
Thanks very much for the help and the sample scene. Your scene works
perfectly here and it's really clear how to set it up :-). It seems like
a really elegant solution...
In my own scene, I guess I'm screwing something up because although I've
input the relevant parameter and events into the PType, I'm currently
getting an error: #ERROR : Object required - [line 12]. I just need to
dig around for some obvious syntax/transposition error I've made.
Thanks for the pointers, again. Very much appreciated.
Julian
