其实上面的循环这样写太复杂了。对于数组这样的集合类型,还有一种更简单的循环方式,这就是for in循环。 for后面是一个变量名,这个变量会在每一次循环中拿到数组中的一个元素,随后就可以在循环代码块中引用它。 字符串也像数组一样 实际上字符串也可以这样用: 在某些场合我们称这类数据结构为可迭代(iterable)对象,也就是说它们可以逐个
# If statement if age > 3: print("Godot is mature.") # For loop for i in range(5): print(i) godot中的流程控制语句包括条件判断、循环、迭代等。关于这部分我们后边会有专门的章节讨论。 3.3.3 函数 函数是一组组织好的、可重复使用的代码,它可以完成特定的任务或计算并返回结果。函数可以带有参...
var surface_array = [] surface_array.resize(Mesh.ARRAY_MAX) # Vertex indices. var thisrow = 0 var prevrow = 0 var point = 0 # Loop over rings. for i in range(rings + 1): var v = float(i) / rings for j in range(width_segment+1): var u = float(j) / width_segment #va...
Steps to reproduce Make an array, add node references to it, free any of the nodes without clearing the reference, create a for loop to iterate over that array, and make the for loop variable typed to those nodes. Tested this with the code snippet in the issue description. Minimal reprodu...
然后初始化一个 Vector2 的 Array 用来存放点的位置数据。 32 个边由 33 个点组成,在第一个 for 循环里,我们计算这 33 个点应该存在的位置。使用 deg_to_rad 把角度转换成弧度。但是因为人的直觉来看角度的 0 度是 12 点钟方向,但是弧度实际上是把 3 点钟方向作为 0 度。所以这里减 90 度,这样子以...

6. print(dict[i]) # loop iterates the keys, i being "a","b" and c". It prints 0, 1 and 2. # 循环迭代字典中的键,i值变化是 a,b,c,打印结果是0,1,2 7. 8. for i in range(3): 9. statement # similar to [0,1,2] but does not allocate an array # 类似[0,1,2],但是...
This is strange because the typing isexactlythe same. This bug does not appear when calling on the host (id = 1), but it does appear when it is called on a peer (id != 1). This bug also appears if I define the type of cardsToPassIn above the for loop, and it also occurs if...
In its update loop, you write all the conditions for it to do all these actions, and it goes just fine.CharacterBody2Din Godot makes it especially easy to detect if the character is jumping thanks to theis_on_floor()function. Simple enough! Now, what if you want the player to be abl...
