How to change everty particle size during runtime? Like , make x and y always the same.

this kind of code does not take effect

I want to change some of them, not all of them, or just some axis.
Still thx

 

So basicaly it's ParticleSystem.MainModule.startSize3D
that means that you need to declare a MainModule to acceed to the startSize3D property (or any other one...)

Now you want to change some of them. you mean some of the PS ? this is just Logic, nothing to do with PS specificaly. You need an IF statement that says "Oh, change the startSize3D of this PS. Oh not this one..."
You can use layers, tags or whatever relativ to your PS.

In a second time you would change some axis only. startSize3D is a Vector3 so you can assign values to its axis as you want (or almost). I use a simple example. No array...

Code (CSharp):

1. psmain.startSize3D =  new Vector3(newValueX, newValueY, newValueZ);

Now If you want to change just some axis (lets say the Y axis) keeping the others as they are you can say

Code (CSharp):

1. psmain.startSize3D =  new Vector3(psmain.startSize3D.x, newValueY, psmain.startSize3D.z);

Hope i understood what you need...
