Wrapping negative numbers
Need a little help. I'm trying to wrap numbers but it needs to allow for negative numbers. This is what i got but it keeps clamping instead of wrapping. ie Debug.Log (Wrap(-210, -120, 120)); should = 50
public float Wrap( float Target, float LowerBound, float UpperBound)
{
float range_size = UpperBound - LowerBound + 1;
if (Target < LowerBound)
Target += range_size * ((LowerBound - Target) / range_size + 1);
return LowerBound + (Target - LowerBound) % range_size;
}
I think what you trying to do is:
public float Wrap( float Target, float LowerBound, float UpperBound){
float dif= UpperBound - LowerBound;
if(Target > LowerBound)
return LowerBound + (Target - LowerBound) % dif;
Target = LowerBound + (LowerBound - Target);
float tmpVal = LowerBound + (Target - LowerBound) % dif;
return UpperBound - tmpVal;
}
I think this should work. I can't test it. Can you try?
