Question by underhand · Oct 15, 2019 at 08:05 PM · physics2dcollider2doverlap

Physics2D.OverlapBoxNonAlloc not return all overlapped collider

Hello, I have a problem with the method Physics2D.OverlapBoxNonAlloc. Actually I used the command like this: int num = Physics2D.OverlapBoxNonAlloc(Position, new Vector2(Width, Height), 0, collider2Ds); where collider2Ds is an array previosly allocated. In a overlap situazione like this, where box is egual to the position and dimension of box 2, the only collider returned in the previous array is the collider 2 and not also the collider 1.

At first you need to make sure your "collider2Ds" array is big enough to receive all the expected results. In my case, my enemy can only detect at most 3 players, so that's the size I use and it works fine.

Yes, I confirm that the array is big enough, because, in this case, I have only three colliders (the third is not showed in the image) and the array is allocated in order to receive three colliders.
