Godot取消循环标记后敌人死亡动画仍循环，求问题排查

你的核心问题是death()函数每帧都被调用，重复执行sprite.play("die")——哪怕动画本身没开循环，每帧强制从头播放也会让它看起来一直在循环。另外直接把动画调用放kill()里无效，是因为kill后状态没立刻切换到DEATH，后续follow()里的sprite.play("run")会覆盖死亡动画的播放请求。

修复步骤： #

1. 修改death()函数，避免重复触发动画播放
   加个标记变量，确保死亡动画只在进入DEATH状态时播放一次：

   var death_animation_played = false  # 新增标记变量
   
   func death():
       print("died")
       if not death_animation_played and not sprite.is_playing("die"):
           sprite.play("die")
           death_animation_played = true
       # 可选：动画播放完毕后销毁敌人
       # if sprite.animation == "die" and not sprite.is_playing():
       #     queue_free()
   

2. 优化kill()函数，立即切换到DEATH状态
   直接在kill里切换状态，避免依赖follow()里的判断延迟：

   func kill():
       dead = true
       $CollisionShape3D.disabled = true
       change_state(States.DEATH)  # 新增这一行
   

3. 额外检查动画资源设置
   确认AnimatedSprite3D的"die"动画资源：

   • 取消Loop选项
   • 确认动画的结束帧设置正确，没有意外的循环逻辑
