请求将Godot 3的GDScript脚本适配迁移至Godot 4

核心修改点 #

• onready 语法更新：Godot 4 中将原 onready 关键字替换为 @onready 注解
• 枚举导出方式调整：导出枚举的语法从 export(ANIMATION_TYPE) 改为类型标注式的 @export var animation_type: ANIMATION_TYPE
• 变量类型显式声明：为变量添加明确的类型标注，符合 Godot 4 的静态类型规范

修改后的 Godot 4 GDScript 代码 #

extends Path2D

enum ANIMATION_TYPE {
    LOOP,
    BOUNCE,
}

@export var animation_type: ANIMATION_TYPE

@onready var animationPlayer: AnimationPlayer = $AnimationPlayer

func _ready():
    match animation_type:
        ANIMATION_TYPE.LOOP: animationPlayer.play("MoveAlongPathLoop")
        ANIMATION_TYPE.BOUNCE: animationPlayer.play("MoveAlongPathBounce")
