Hi,
Lets say I have this expression in script controller:
$.turbulence = random 17.0 23.0
So when I run it, it evaluates in realtime. And this is not what I want. I want it to evaluate, lets say on scene opening. How do I do that?
You are probably interested in callbacks, they allow you to run a function after an event happens in max, like an object selection change, a viewport update, or scene open to name a few.
Here is a good place to start looking at how to do this.
please better explain what you want to randomize and at what moment. setting every time your load a scene a new value to controller doesn’t make sense for me.
You want the turbulence to only be assigned once? Or the random value to only be chosen once?
If you just want a single random value, simply assign a seed beforehand.
seed 1234
random 0 10 --will always return: 5
If you only want the turbulence to be assigned once, why do you have it in a script controller?
Well the turbulance was just an example. The point is to have the ability to change some values of some nodes, without running a script manually.
An ideal example is: change turbulance, on every time I recache particles with Krakatoa
I’ve looked into those callbacks, this gives some flexibility.
