GradientValue
Return value notes
Returns a vector that is the color vector between
start and end depending upon percentage if the vector between can be calculated, else returns <-1, -1, -1>Specification
// Created by Ugleh Ulrik
vector GradientValue(vector start, vector end, float percentage)
{
list colorParams = [start.x, start.y, start.z, end.x, end.y, end.z];
if (percentage < 0.0
|| 100.0 < percentage
|| llListStatistics(LIST_STAT_MIN, colorParams) < 0.0
|| 1.0 < llListStatistics(LIST_STAT_MAX, colorParams))
{
return <-1, -1, -1>;
}
percentage /= 100.0;// convert to decimal for further use
return start + percentage*(end - start);
