Speaking of animated bumps

Unity Engine

I want to set a decreasing transparency level and I was thinking it might be more fun and more functional to do it with code … (as the transparency levels could be tweaked without having to go back and forth between programs)
What I’m curious about is setting the transparency levels of a texture map with code … had a quick look through the manual but couldn’t find a reference … do you think it’s possible … or should I stick with importing multiple images with diminishing transparency?

Just set the color.a to equal a value in between 0 and 1. Make sure your using an alpha shader.

I ended up using a few materials … cause I was using a parallaxBump/AlphaDiffuse material and I didn’t know how to apply the color.a to it … here’s the code …

var m1 : Material;
var m2 : Material;
var m3 : Material;
var m4 : Material;
var m5 : Material;
var c = 1;

function Update () {
	transform.localScale.x += 0.05;
	transform.localScale.z += 0.05;
	c = (c + 1);
	if (c < 60) {
		renderer.sharedMaterial = m1;
	}
	if (c == 60) {
		renderer.sharedMaterial = m2;
	}
	if (c == 70) {
		renderer.sharedMaterial = m3;
	}
	if (c == 80) {
		renderer.sharedMaterial = m4;
	}
	if (c == 90) {
		renderer.sharedMaterial = m5;
	}
	if (c == 100) {
	Destroy(gameObject);
	}
}

It’s a bit clunky though … basically the materials have different opacities set to them starting at 5, 4, 3 ,2 ,1 Destroy!! … I’ll keep playing around with it … see if I can get my head around the method you suggested … cheers for now!

check jonathan’s script here:

you could modify this to go to set values instead of fade completely if that’s what you’re looking for but this is the basic idea ; )

I’ll definitely have a look at it tomorrow … in the light of day … it looks like it’s the path to take … thanks
