Libgdx紋理動畫

Question

這是我第一次來這裏，我有一個問題給你。我希望你能幫助我。因此，我在這場比賽中有這個課程，我希望球員在走路時重複動畫。對不起，如果你不明白我，但我的英語是基本的。這是班級。

public class Player extends Actor implements InputProcessor { 

    private final Texture tile4; 
    private final Texture tile5; 
    private Texture tile1 = null; 
    private Texture tile2 = null;

    protected Texture [] tile; 

    public Player(Level level) { 
     this.level = level; 
     tile1 = new Texture("idle.PNG"); 
     tile2 = new Texture("walk a.PNG"); 
     tile3 = new Texture("walk b.PNG"); 
     tile4= new Texture("walk c.PNG"); 
     tile5= new Texture("walk d.PNG");

     character.height = 80;

我相信this教程做了解釋的一個相當不錯的工作libGDX的Animation類是如何工作的，這是我會強烈建議您使用。
