MapValue() takes an input in one range and remaps it to another. Very useful for AI and scripting.

MapValue.cs

public static float MapValue(float inVal, float inFrom, float inTo, float outFrom, float outTo) 
{
    float inScale = (inFrom != inTo) 
        ? ( ( inVal - inFrom ) / ( inTo - inFrom ) ) 
        : 0.0f;
    float outVal = outFrom + ( inScale * ( outTo - outFrom ) );
    outVal = (outFrom < outTo ) 
        ? SomeClampFunction( outVal, outFrom, outTo ) 
        : SomeClampFunction( outVal, outTo, outFrom );
    return outVal;
}
