让多只海龟同时移动

Question

节目的想法是什么：我们有看门狗，羊，狼。我的羊在浅滩里，狼从外面来了，一进入浅滩，看门狗就开始行动了。狼吃羊，羊吃草，看门狗要吓唬狼（暂未实现）

我的问题：所有的海龟一次移动一只。

我想要的：我希望它们在每个滴答声中同时移动。

代码:

    breed [sheeps sheep]
breed [wolves wolf]
breed [watchdogs watchdog]

turtles-own [attacked?]

globals [counter
  attack
  sheep-energy
  wolf-energy
  grass-counter
  lifespan
  age
  num-attacks
  death-countdown]

to set-variables-shapes
  set lifespan 365 * 10
    set-default-shape sheeps "sheep"
    set-default-shape watchdogs "dog"
    set-default-shape wolves "wolf"
     set sheep-energy 200
     set wolf-energy 400
     set death-countdown 60
end

Answer 1

您可以使用

ask-concurrent sheeps [move ]

让每个绵羊代理都同时移动，不过应该没关系，他们实际上不建议你使用它。

Answer 2

NetLogo中没有"at the same time"这样的东西。 NetLogo 是单线程的，不支持并行处理。

如果所有代理在同一个时间点内移动，您可以将其视为 "at the same time"，因为这一切都发生在一个时间点内。

但是在一个滴答声中，除了一次移动一个以外，代理几乎没有其他办法。
