So I'm trying to make it so that the boss bars show the current experience of the player. For example if the player is level 1 the max experience will be 200 until level 2. So how can I make it so that the progress bar sets the progress of the player experience? This is what I got so far: Code (Text): public void progressBarExperience(Player p) { int playerLevel = Experience.getLevel(p); switch(playerLevel) { case 1: double experience = Experience.getExperience(p) * 1 / 200; bar.setProgress(experience); break; case 2: double experience1 = Experience.getExperience(p) * 1 / 400; bar.setProgress(experience1); break; case 3: double experience2 = Experience.getExperience(p) * 1 / 500; bar.setProgress(experience2); break; case 4: double experience3 = Experience.getExperience(p) * 1 / 800; bar.setProgress(experience3); break; case 5: double experience4 = Experience.getExperience(p) * 1 / 1000; bar.setProgress(experience4); break; }
