Godot角色向上移动时报Animation not found动画不存在错误

• 项目角色已配置右、左、上三个方向的移动动画，运行时动画视觉上可正常播放，但控制台持续输出报错：play: Animation not found: Run_Up、play: Animation not found: Idle_Up
• 报错仅在角色向上移动时触发，切换到其他方向移动后报错立即停止

var ACELERACION = 350
var FRICCION = 850

enum {
    RUN,
    PUSH
}

func _play_animation(animation_type: String) -> void:
    var animation_name = animation_type + "_" + _get_direction_string(direccion_vector.angle())
    
    if animation_name != animation_player.current_animation:
        animation_player.stop(true)
    
    animation_player.play(animation_name)

func _get_direction_string(angle: float) -> String:
    var angle_deg = round(rad2deg(angle))

    #glanced up
    if angle_deg == -90:
        $RayCast2D.rotation_degrees = 180
        return "Up"

    #glanced down
    if angle_deg == 90:
        $RayCast2D.rotation_degrees = 0
        return "Right"

    #glanced left
    if angle_deg == 180:
        $RayCast2D.rotation_degrees = 90
        return "Left"
    
    #glanced right

    return "Right"

1. 方向判断逻辑容错性为0：_get_direction_string用==对浮点运算得到的角度做精确等值判断，斜向输入、轴值漂移、浮点精度误差都会导致角度值不是刚好的-90/0/90/180，出现方向匹配错误。初始值direccion_vector = Vector2.DOWN对应90度角被直接映射为Right，本身逻辑就不严谨。
2. 动画播放逻辑缺失校验：_play_animation每帧都会调用animation_player.play()，既不校验拼接出的动画名是否真实存在，也不在当前已在播放目标动画时跳过调用，无效调用反复触发控制台报错。
3. 动画名匹配存在偏差：Godot动画名大小写敏感，若AnimationPlayer中存储的向上方向动画名和代码拼接出的Run_Up/Idle_Up不完全一致（比如命名为Run_up/Idle_up），就会触发找不到动画的错误。

1. 打开AnimationPlayer面板，核对所有动画名，确保右、左、上三个方向的Run/Idle动画命名严格为Run_Right、Run_Left、Run_Up、Idle_Right、Idle_Left、Idle_Up，大小写完全匹配。
2. 替换原有_get_direction_string和_play_animation函数，改用角度区间判断方向，增加动画存在性校验，避免重复调用play接口：

func _play_animation(animation_type: String) -> void:
    var dir_str = _get_direction_string(direccion_vector.angle())
    var animation_name = animation_type + "_" + dir_str
    # 动画不存在时直接跳过，不触发播放
    if not animation_player.has_animation(animation_name):
        return
    # 仅在未播放目标动画时才切换，避免每帧重复调用play
    if animation_player.current_animation != animation_name:
        animation_player.play(animation_name)

func _get_direction_string(angle: float) -> String:
    var angle_deg = round(rad2deg(angle))
    # 负角度转正，简化区间判断
    if angle_deg < 0:
        angle_deg += 360
    
    var dir: String
    # 按45度区间划分四个方向，覆盖斜向输入场景
    if angle_deg > 315 or angle_deg <= 45:
        dir = "Right"
        $RayCast2D.rotation_degrees = -90
    elif angle_deg > 45 and angle_deg <= 135:
        # 下方向暂时映射为Right，后续补充下方向动画时可直接改为Down
        dir = "Right"
        $RayCast2D.rotation_degrees = 0
    elif angle_deg > 135 and angle_deg <= 225:
        dir = "Left"
        $RayCast2D.rotation_degrees = 90
    elif angle_deg > 225 and angle_deg <= 315:
        dir = "Up"
        $RayCast2D.rotation_degrees = 180
    
    return dir
