使用get_node('../root/node_path')方式,不推荐并表示强烈谴责,这会造成强耦合,扩展、维护和重构极其困难 使用Global AutoLoad,也就是 Singleton 单例模式,有效解决耦合,但是维护相当困难,牵一发而动全身,调试困难 使用Resource 创建相应的事件资源,强力解耦,使用起来非常方便,调试也非常简单,易扩展和维护 关于第二...
由于获取节点这个操作太常用了,Godot 就设置了个语法糖,使用美元符号$即可直接代替get_node方法调用: $FirePosition等于get_node("FirePosition") $/root/Node2D/Control等于get_node("/root/Node2D/Control") 如果路径包含特殊符号导致语法出错,也可以把$后面的东西用字符串表示:$"../Control"等于get_node(".....
