hey everyone,

I wanted to know if anyone would know how to go about doing this in c-script. Say I have an animation, maybe of a model opening its mouth made in 10 frames. I have a distance value between 2 points. If the distance value is say at max 300, I need a formula that will put the animation of the model at the 10th frame, based on the distance value. So:

If the distance value is at 0, the animation is at frame 0.
If the distance value is at the 300 max, the animation is at frame 10.

What formula could I use so that any distance between 0 and 300 would correlate to a frame of animation? Can the formula accomodate different total frames of animation and different max distances?

something like this:

my.frame = distance / max_distance * 10; //max_distance = 300

should be like this:

frameNo = (int)((float)actDist / ( (float)maxDist / (float)( frameCount - 1 ) ))+1

c-script takes care of type casting for you, so you don't have to worry about all the mess. Also, ".frame" accepts fractions as well (for interpolating), so converting to integer isn't necesary...

@xXxDisciple

Yes I know that c-Script and LiteC care of type casting, but I want to control exactly what happens.

For example: If the used variables (maxDist etc.) are declared as int than there will be to many rounding errors.
It might not be a problem in the case of this animation-cycle but it could be in other circumstances. So I always use casts to be sure what happens.

...Understandable, and indeed a good habit

thanks for the input guys, though I am a little lost as to what the difference between these two are:


This one uses more hard scripted values am I correct?:

my.frame = distance / max_distance * 10; //max_distance = 300.

Does this one seem more flexible, because the values can be defined beforehand such as max distance?:

frameNo = (int)((float)actDist / ( (float)maxDist / (float)( frameCount - 1 ) ))+1

Why is there (float)?, sorry Ive never used float in C_Script yet.

type casting won't work in c-script. Only in Lite-C...

...Use the first one
