How to check if the difference between any pair of numbers in an array is less than some value?
Hello guys!!
EXPLANATION: So I have an array of Speed values and I want to check if the difference between any pair of numbers is less than 1. If so, bool = true. This is what I have so far:
public float[] speedArray;
public bool changeSpeed;
void Update()
{
for (int i = 0; i < speedArray.Length; i++)
{
for (int j = i + 1; j < speedArray.Length; j++)
{
if (Mathf.Abs(speedArray[i] - speedArray[j]) < 1f)
changeSpeed = true;
else
changeSpeed = false;
}
}
}
PROBLEM: The problem is that with this code it doesnt immediately set changeSpeed = false, because some differences can be > 1... For example: if i have {0.5, 0.75, 2} it will return changeSpeed = true (between 0.75 and 0.5) and changeSpeed = false (between 0.5 and 2 / between 0.75 and 2).
ANSWER?: I think that the answer is to introduce a WHILE loop instead of the IF loop. However, I dont know how to do it, I have never used WHILE loops because once I used them and Unity crashed...
Thanks in advance!!
changeSpeed |= $$anonymous$$athf.Abs(speedArray[i] - speedArray[j]) < 1f;
or
if( $$anonymous$$athf.Abs(speedArray[i] - speedArray[j]) < 1f )
{
changeSpeed = true;
break;// stops this for loop
}
