Hi Spencer,

thanks for this very useful piece of information !

Of course it would make sense to have functions like Michael showed included in Std or Math,

but to be able to run your own .ck files automatically at startup is also a feature that is ridiculously useful, do you think it can also be included in the next version of mini-audicle ?

Cheers,

Casper

Hey Michael,

Yeah, these are super useful functions. I have these and a few others defined in a public class called "Std2" whose source file is in my chugin directory. ChucK executes .ck files in the chugin directory at launch, so they are pretty much available for general usage on my system. I think in the future it would make sense/be easy to have these builtin to the language itself though.

Hello,

I find myself using the following all the time and was wondering how
difficult it would be to add them to Std or Math

    fun static int constrain(int value, int min, int max)
    {
        if (value < min)
        {
            return min;
        }
        if (value > max)
        {
            return max;
        }
        return value;
    }

    fun static float constrainf(float value, float min, float max)
    {
        if (value < min)
        {
           return min;
        }
        if (value > max)
        {
            return max;
        }
        return value;
    }

    fun static float interp(float value, float sourceMin, float
sourceMax, float targetMin, float targetMax)
    {
        return targetMin + (targetMax - targetMin) * ((value -
sourceMin) / (sourceMax - sourceMin));
    }

Thanks,

   michael
