How to register only one OnMouseDrag in Unity?

Question

Unity

There is an OnMouseDrag method, it registers clicks on the screen. The problem is that I use this method on Android, and if I press with several fingers, then bugs occur. Is it possible to fix this so that only the first tap on the screen is registered?

Answer 1

The android for the unit has its own methods of tapping the screen.
Here is the documentation on touches (clicks on the screen): https://docs.unity3d.com/ScriptReference/Touch.html
What you need to detect is only one tap on the screen, because in your case the engine registers all fingers on the screen, so it gives an error .
In Update() write something like this:

if (Input.touchCount == 1)
{
 выполнить после 1 нажатия
}
