How do built-in auto called function actually work ?
Hello everyone !
I have a question concerning functions that are called automatically when some events occur. Functions like OnMouseEnter(), OnMouseExit(), etc. I am wondering what happens behind these. Are they kind of checked up in an hidden Update function at each frame ?
For instance, is there any gain of performance using OnMouseOver() rather than coding it yourself like following :
// I assume IsMouseOver() is a custom function that returns true whenever the mouse is hovering the object this script is attached to.
private void Update()
{
if (isMouseOver())
{
Debug.Log("Hovering");
// Do whatever you want here
{
}
Regards
Every frame, Unity follows an event queue, The update is one event, and handling events is another event, you can read more here:
https://docs.unity3d.com/Manual/ExecutionOrder.html
Unless you are a senior experienced programmer, most likely all functions done by unity itself have a better performance.
I did not know about the detail of this. Thank you very much!
