Ich bin neu in Codierung und UnityUnity 2D Gesundheitsbar
ich die Health-Bar auf meinem Bildschirm erscheinen, aber ich bin nicht sicher, wie die Gesundheit Skript der Health-Bar auf meinen Player Skript zu verbinden und meine Spielern Gesundheits-Skript. Einfach, ich will es so machen, wenn mein Player meine Gesundheit Bar erschossen wird
