My script, as you can see, Destroys gameObject on the first click on it. If there’ s more gameObjects and i click on them faster, some of them need 1 click to destroy (that is what i want) and some of them need several clicks to destroy (is it because of the detection of my click is not called every frame? Or i don’t really know) Script is atrached to gameObject.
A quick search resulted in the following similar issues:
OnMouseDown() Doesn't work - Questions & Answers - Unity Discussions (check the second highest voted answer as well!)
So it seems the problem can be caused by various reasons:
incorrect setup (e.g. no collider on the object)
camera view issues (too close to the camera or not seen by the main camera)
another collider is blocking the view
Apart from these, how fast does your application run? At 60 FPS it is not very likely that you are clicking faster than a frame, even if I assume that OnMouseDown() is synced to the physics update. Which means the problem has an issue in the logic.
