Details on How Does the Overlap Function Works

[rocketappliances]

Hi Everyone,

I have been debugging my game to fix a problem where my character gets stuck in platforms. It doesn't happen often but randomly he gets stuck in a wall as he overlaps the wall. I move my player using fastloops one pixel at a time and do an overlap check with a detector prior to the movement. The problem occurs even without jumping.

When debugging I recorded the left and right edge positions of my detector and the edges of object I am getting stuck in. The coordinates overlap but there is no overlap being detected by clickteam fusion 2.5. I feel like I'm losing my mind lol. Any ideas on why it is not catching the overlap? Note that the error is within a pixel.

post an example of the bug

I have a detector that is 1 pixel by 1 pixel. Using a fast loop I scale it and position it infront of my player. In the next event of the fastloop I check for overlap with the detector. It is not detecting the overlap. I will post pictures of the relevant events. One second.

Let me know if you can't read these because on my computer they look alot clearer I don't know why the forum degraded the quality of the attachments.

Update: I have flags that go on and off after the fastloop movement. Also they record the edges of the detectors and the platform. The numbers show that the two objects overlap however the overlap condition is not activated.

Does the check overlap condition not work if you take an object that is 1pixel by 1 pixel and scale it to the desired size then check for overlap in the same frame/fastloop?

If anyone has answers I would love to hear them

im not able to type out a long response right now because i had my keyboard break and am resorting to OSK. I think it very well might be the scaling, but im not sure. Does it only happen on specific sides, or is it universally inconsistent? Going out tomorrow for new KBD, hopefully King_Cool chimes in

Thanks for the reply. I'm starting to think now I have to program my own collision detection if I want my game to work

check the other thread. i posted an example there.
