这里我们需要用到循环(loop)来减少重复的代码。 当… 为了输出数组中的诸元素,我们可以用一个变量来记录当前print到哪里了。只要这个值还没超过数组的长度——准确地说是“最大有效索引”——我们就继续print。 这里可以到while循环。while循环的语法如下: 只要while后面的条件满足(也就是说为真),while下方的代码块...
也是很简洁,除了平台相关的人机交互接口(鼠标/键盘/触摸/游戏手柄等)处理外,while 循环中,其他业务由 Main::iteration 完成 Main::iteration 和其他引擎的 loop 基本一致 Main::iteration loop: 计算 fps 物理引擎 update 显示引擎 draw update 脚本引擎 frame process 音频引擎 update 最后在 Main::cleanup 中做了...

Cleanup loops which are linear scan but use while. Semantically, this change provides greater optimization potential because we can now batch free elements. However, this benefit can only be realiz...
复制代码while 可以用break或continue 1. while [expression]: 2. statement(s) 1. 2. 复制代码for 范围迭代。 1. for i in [0,1,2]: 2. statement # loop iterates 3 times, i being 0,1 and 2 # 循环迭代三项,i的值变化是0,1,2
I just play the game for a while and it crashes seemingly randomly, sometimes it's 5 minutes into the game sometimes it's a few seconds into it. It mostly crashes after I do an action but sometimes when I'm idling as well.
NPCs and the player can fall from platforms, NPCs can be pushed up on platforms, and they can find their way back to the player, while everything is in 2D. Map development became quite smooth, so it's really not hard to add more zones. The few things I now need to work ou...

30、e node and delete it while nothing ishappening初始化场景从代码初始化场景非常简单,有两种方式。第一种是从磁盘加载场景python var scene = load() # will load when the script is instanced有些时候,使用 preload会更方便,因为,它在解析时执行。python var scene = preload() # will load when parsi...
