Godot 获取editor camera的hack方法

Godot中想要自己制作editor plugin的话，可能你需要获取编辑器相机参数，现在API并未提供接口，所以只能用比较hack的方式获取。代码如下

func get_editor_camera(camera_index):#get camera in the spatial editor(4 camera in spatial editor)

var e = get_editor_interface().get_editor_viewport()

var cam = e.get_child(1).get_child(1).get_child(3).get_child(0).get_child(cam_index).get_child(0).get_child(0).get_camera()

# If the function not work, use code below to check(new version godot change the camera hierarchy)

var root = e.get_parent()

var all_nodes = []

var c = root.get_children()

while !c.empty():

var child_list = []                        

for i in c:

child_list += i.get_children()

all_nodes += child_list

c = child_list

for node in all_nodes:

if node.get_class() == "Camera":

print(node.transform)

print(node.get_path())

for i in range(deep):

node = node.get_parent()

print(node.get_class() + str(node.get_index()))

print(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>")

return cam
