Hi all, I have a simple gradient texture I’m using for an energy bar. I start with full energy, and green color for the bar. I can’t quite figure out Color.Lerp. I want to fade from green, to yellow, to red as the energy runs down, and smoothly back to green as energy increases. I can get color to fade to another, but can’t quite come up w/ a proper formula to address my needs…
You just need to split it up into 2 different Lerp
s:
if (health < .5) {
blendColor = Color.Lerp (Color.red, Color.yellow, health*2);
} else {
blendColor = Color.Lerp (Color.yellow, Color.green, (health-.5)*2);
}
The basic pseudo code would be:
var maxEnergy : flaot;
var energy : float;
var greenColor : Color;
var redColor : Color;
Color.Lerp(redColor, greenColor, energy /maxEnergy);
Though you will need to put the last line in a method, presumably the Update function.

EDIT:
just reread your question and completely missed the 3rd color part, it was 1 in the morning :S
@Kiloblargh’s answer is perfect (you could replace health with the energy/maxEnergy)
Sorry about that!
