How to import number from scene 1 to scene 2?

Question

How can I import number from another scene? For example:

scene1 script

if(...) {
   a = 1;
} else {
   a = 0;
}

How to import a to the next scene?

You can do this by using a as a static variable. it will keep the value.

public static int a;

Bad idea, that static value will stick around for some time and become a possible source of bugs. – Arshia001 Apr 23 '19 at 13:28
Values can be passed to another scene in various ways. most common of them are: * PlayerPrefs * Static variables – Muhammad Farhan Aqeel Apr 23 '19 at 13:32
Indeed, but statics have caused me quite a few headaches before. – Arshia001 Apr 23 '19 at 13:33

The way I do this is by making the scene load async, and passing the value through code to the object that's supposed to receive it in the next scene:

var valueToPass = 2;
var asyncOp = SceneManager.LoadSceneAsync("otherScene");
asyncOp.OnCompleted += () => 
{
    // this code runs once the second scene is loaded
    FindObjectOfType<SomeOtherObject>().PropertyToFill = valueToPass;
}

I wrote the code off the top of my head, it probably won't compile (didn't have Unity on hand to test it) but that's the general idea.
