I need a math whiz, please? :-D

Ok, what I'm working on is something that has a progress bar in it.

I have a texture that I can change the offset of to make the progress bar show progress, but I am not good at the math needed to make it scale automatically.

Basically, when the Vertical Offset is is -0.20 it's at 0%... when it's at +2.0, it's at 100%.

Can someone write me up some code to calculate what I need to set the offset at if I feed it the percentage? Like if I can calculate that the progress bar should be at 44.2% done, what offset should I set the texture to?

I would be willing to pay a little bit for this, if it comes to it.

Thanks!

I think this should do it:

offset = -0.2 + (2.2 * progress); //progress is a float between 0.0 and 1.0

Hehe, Seifert beat me to it!

float percentage;
float textureoffset;
// At the header of the script we'll define these. Within your script you'll assign values to percentage. Then I'd make a function like...

updateloadtime()
{
textureoffset = percentage * 2.2;
textureoffset = textureoffset -0.2;
}

// Then have your script set percentage to say 44.2, and call the function updateloadtime()...

Careful with percentages - you'd need to divide by 100.0 at some point ;-p.

Thanks! It's working great!
