在 LibGDX 中是否有一个动画演员(需要一个动画)并且当添加到舞台时会自行动画,还是您必须在其中实现自己的 Image 类并自己为其制作动画?

我只是创建了一个“AnimatedImage”演员类,它只接受一个动画作为参数(不需要自定义的 Drawable 类)。我认为这个解决方案比上面的解决方案简单得多。
动画图像.java:
public class AnimatedImage extends Image
{
protected Animation animation = null;
private float stateTime = 0;
public AnimatedImage(Animation animation) {
super(animation.getKeyFrame(0));
this.animation = animation;
}
@Override
public void act(float delta)
{
((TextureRegionDrawable)getDrawable()).setRegion(animation.getKeyFrame(stateTime+=delta, true));
super.act(delta);
}
}

就像你一样,我没有找到动画演员,所以我创建了自己:
动画演员.java:
public class AnimatedActor extends Image
{
private final AnimationDrawable drawable;
public AnimatedActor(AnimationDrawable drawable)
{
super(drawable);
this.drawable = drawable;
}
@Override
public void act(float delta)
{
drawable.act(delta);
super.act(delta);
}
}
AnimationDrawable.java:
class AnimationDrawable extends BaseDrawable
{
public final Animation anim;
private float stateTime = 0;
public AnimationDrawable(Animation anim)
{
this.anim = anim;
setMinWidth(anim.getKeyFrameAt(0).getRegionWidth());
setMinHeight(anim.getKeyFrameAt(0).getRegionHeight());
}
public void act(float delta)
{
stateTime += delta;
}
public void reset()
{
stateTime = 0;
}
@Override
public void draw(SpriteBatch batch, float x, float y, float width, float height)
{
batch.draw(anim.getKeyFrame(stateTime), x, y, width, height);
}
}
