libgdx动画的java问题
当我尝试为动画设置播放模式时,我遇到了特定行的问题
根据this API,我有以下可能性:
- 循环
- 乒乓球
- 循环随机
- 反循环
- 正常的
- 颠倒
但是,在执行以下操作时:
import com.badlogic.gdx.graphics.g2d.Animation;
...
spriteAnimation.setPlayMode(Animation.LOOP_PINGPONG);
我得到LOOP_PINGPONG cannot be resolved or is not a field
。这是什么原因?在我看来,它在API中是可行的吗
编辑:
我应该声明,我正在使用libgdx跟踪gamedev的guide。但是导游已经一岁多了,所以我不能在那里寻求太多帮助

下面是动画类的源代码
正如您所看到的,枚举实际上被称为“播放模式”,所以不要这样做:
你应该这么做

由于您已导入以下内容:
你也可以用这个:

我想试试。我查看了libgdx Github目录,发现PlayMode是一个枚举
