public class Playercollision : MonoBehaviour
{

void Update()

    n = Random.Range(-100, 100);
    n2 = Random.Range(-100, 100);
}

}

int n2 = 0; int n = 0;

Should be placed inside your public class.

Thank you so much my I was having troubles with a lot of simple things that I just could not think of how to fix. I am also a noob XD so I don’t really know much about where stuff is supposed to be.
