So the player needs to inform the UI, which sounds like a perfect use case for get_tree().get_root().get_node("UI/healthbar") or something similar. So what do you do if you aren't allowed to use get_tree() or get_parent() or get_node("..")? You use signals. A signal is...
get_node("/root/MyGame") Array get_node_and_resource ( NodePath path ) Node get_node_or_null ( NodePath path ) const 与get_node类似,但在path未指向有效节点时不会引发错误Node。 Node get_parent ( ) const 返回当前节点的父节点,Node如果节点缺少父节点,则返回空。 NodePath get_path ( ) co...
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(".....
This provides native browser support, and results in a small overhead from the build process. To build the project locally you need to have Node.JS installed (12.x and newer should work just fine). This project uses GitHub's GraphQL API. To fetch live data you need to generate a ...
In that node if you run the code: func _ready(): print(get_node("/root")) You will see: So, no matter how you create your scene, you will always have at least one viewport. On the other hand, you can create more viewports within the scene as we will see later. ...
其中get_drag_data()实现“拖起”,can_drop_data()、drop_data()用于实现“放下”。 因为源要实现“拖起”,所以需要在控件A的代码中实现get_drag_data(),而要实现在控件B中处理“放下”,所以需要在控件B的代码中实现an_drop_data()和drop_data()。
实际上每个(Node2D和Node3D)节点的transform都分transform和global_transform。前者实际上是局部(local)transform。为什么要分这个东西呢? 因为一个物体的位置、朝向信息在不同坐标系中有不同的值。 全局(或者说世界)坐标系就相当于一个最上层的根节点,在它之外就没有其它东西了,它自己也不会动。这样场景中每个东西...
