godot 调用class方法得用实例不能用脚本引用

var enemyplay=preload("res://scripts/EnemyBall.gd")

不能用enemyplay.play调用

得用

func _handle_pocketed(body: RigidBody2D):

if "Enemy" in body.name or "enemy" in body.name:

body.play("xiao")

body.play调用

错误提示说明你在某个地方用 EnemyBall.play() 或 WhiteBall.play() 这种"类名.方法"的形式调用了实例方法。play() 是每个球的实例方法，必须通过实例（比如 self.play() 或某个敌人对象.play()）调用。

检查一下你的代码，你是不是写成了这样：

go 复制代码

gdscript
# 错误写法
if something:
    EnemyBall.play()   # 错：EnemyBall 是类，不能直接用类名调用实例方法
要改成：

go 复制代码

gdscript
# 正确写法
self.play("xiao")  # 自己播放
# 或者
enemy_instance.play("xiao")  # 特定敌人实例播放

go 复制代码
