find() & rfind() find()返回找到的第一个相同元素的位置,找不到返回-1。 rfind()从末尾开始逆序查找,返回找到的第一个相同元素的位置(索引),找不到返回-1。 @tool extends EditorScript func _run(): var arr = [0, 1, 2, 3, 4, 5, 6, 4, 8, 9]; print(arr.find(4)) # 4 -- 从左...
我们如何获得场景中所有的Sprite2D而不用挨个创建变量呢? 这里用到一个叫find_children的函数。顾名思义它可以找到脚本所在节点的孩子节点。它的第一个参数是节点路径,第二个可选参数是节点类型。在这里我们想要找到所有的Sprite2D,所以第一个参数留一个通配符就好,第二个参数填入Sprite2D。注意是字符串,可以在文档...

为Enemy节点添加脚本,并添加变量: onready var nav_2d = get_parent().find_node('Navigation2D') onready var target = get_parent().find_node('Player') var speed = 40.0 var path = PoolVector2Array() Nav_2d 和target 都是节点的引用,关于节点的引用依据你的节点结构,所以,不一定都如上代码,可...

find_all elements in an array that match a condition? I've an array of hash entries, and want to filter based on a paramater passed into the function. If there are three values in the hash, A, B, and C, I want to do something similar to: find all where A......
I'm sure I've seen this discussed, but I must not be using the right keywords because I can't find anything on it now: I have a desktop application using NHibernate persistence. I'd like to use the se...media query sizing and positioning font I've got some text I'd like to ...
The next time you have a crash, try to find a pattern and remember your steps that led to the error, create an empty project and try to repeat the same thing, you may have to import some resources if that is the issue. It is not so easy to recognize the problem from a single dum...
Besides that, I also changed the External Editor from MonoDevelop toVisual Studio Code. Visual Studio Code is nice for the C# project. It has autocompletion and able to find function definition and function references. Previously, because I was using MonoDevelop, the Nuget packages (similar to ...
varenemies:Array=[$Goblin:Enemy,$Zombie:Enemy] 你不能强制在for循环中分配类型,因为for关键字循环已经具有不同类型的每个元素。所以你不能写: varnames['John','Marta','Samantha','Jimmy']forname:Stringinnames:pass 两个脚本不能以循环方式相互依赖: ...
