假设我们有一个场景，该场景以空间节点为单位，名为 node_of_interest 带有儿童 mesh_of_interest ，源代码中的某个地方是否可以访问这些节点？
我以为Scenetrey将是正确的起点，因为它具有 节点 * current_scene ，但是当我在断点在这里
我从未看到 current_scene 不是null。
我觉得有了这些信息，我将更好地了解节点与服务器和驱动程序的关系。
这是我在尝试的场景。
Say we have a scene that starts with a spatial node named Node_of_interest with a child Mesh_of_interest, is there somewhere in the source code where we can access these nodes?
I assumed the SceneTree would be the right place to start since it has Node * current_scene , but when I step through in the debugger on a breakpoint here
I never see current_scene as not null.
I feel like with this information I'll have a much better handle on how the nodes relate to servers and drivers.
Here's the scene that I'm trying this on.
