-- Setup frames when script runs
setupFrames()

In this script it detects when the mouse is being dragged over any of the 26 frames and turns them green when it is, but it seems the detection is very buggy and barely ever correctly detects when it is being dragged over, any reason why?

I’ve had very similar issues in the past. I think it works if you use player:GetMouse().X, and player:GetMouse().Y. Also, you should use PlayerGui:GetGuiObjectsAtPosition().

Yea I fixed it, the problem was I was using MouseLocation() instead of GetMouse() which didn’t get the correct position of the mouse
