【问题描述】：

我的movement animation 没有播放。我的角色仍然摆姿势表演，但在移动时它保持在那个静态位置。 animation loop 似乎没有播放。

我的代码如下：

public class Char extends Sprite {

  public enum State {   STANDING, RUNNING };
  public State currentState;
  public State previousState;
  TextureRegion region;
  private TextureRegion Still;
  private Animation Go;

  private float stateTimer;

  public World world;
  public Body b2body;

  public Char(World world, PlayScreen screen){
    super(screen.getAtlas().findRegion("NewRun"));

    currentState = State.STANDING;
    previousState = State.STANDING;
    stateTimer = 0;

    Array<TextureRegion> frames = new Array<TextureRegion>();

    for(int i = 1; i < 4; i++)
      frames.add(new TextureRegion(getTexture(),i* 53,0,53,48));
    Go = new Animation(0.1f, frames);

    frames.clear();

    Still = new TextureRegion(getTexture(),0,0,53,50);
    setBounds(0, 0, 50 / Game.PPM, 65 / Game.PPM);
    setRegion(Still);
    this.world = world;
    defineChar();
  }

  public void update(float dt) {
    setPosition(b2body.getPosition().x - getWidth() / 2, b2body.getPosition().y - getHeight() / 2);
    setRegion(getFrame(dt));
  }

  public TextureRegion getFrame(float dt) {
    currentState = getState();
    switch(currentState){
      case RUNNING:
        Go.getKeyFrame(stateTimer, true);
        break;
      case STANDING:
      default:
        region = Still;
        break;
    }

    stateTimer = currentState == previousState ? stateTimer + dt : 0;
    //update previous state
    previousState = currentState;
    //return our final adjusted frame
    return region;
  }

  public void defineChar(){
    BodyDef bdef = new BodyDef();
    bdef.position.set(50/ JoD.PPM, 20/ JoD.PPM);
    bdef.type =BodyDef.BodyType.DynamicBody;
    b2body = world.createBody(bdef);

    FixtureDef fdef = new FixtureDef();

    CircleShape shape =new CircleShape();
    shape.setRadius(4);

    fdef.shape= shape;
    b2body.createFixture(fdef);//.setUserData(this);
  }

  public State getState(){
    if(b2body.getLinearVelocity().x != 0)
      return State.RUNNING;
    //if none of these return then he must be standing
    else
     return State.STANDING;
  }

}

我查看了多个教程，但不明白为什么动画无法播放。
谁能看到我错过了什么？

【问题讨论】：

你能保证 Sprite 正在接收更新事件吗？您是否明确将状态设置为 RUNNING，动画是否有效？

【解决方案1】：

您是否错过了 getFrame(float dt) 方法中对区域的分配？你画的区域总是“Still”？？

switch(currentState){
      case RUNNING:
        //Go.getKeyFrame(stateTimer, true);
        //Should be ...
        region = Go.getKeyFrame(stateTimer, true);
        break;
      case STANDING:
      default:
        region = Still;
        break;
    }
