修补程序集代码上的繁殖无法正常工作

Question

招募过程的代码在模型的多次迭代中都运行良好，但最近第一只海龟似乎从食物中跳了出来，并将颜色变为橙色，这可能是寻找食物过程的一部分，而不是改变品种变白。如果乌龟进入食物贴片区域，它似乎工作顺利，但它们似乎接触到了食物贴片的边缘，并以某种方式触发了寻找食物的程序。或者，缩写为go的代码中的品种转换(询问领导者…设置品种觅食者，设置颜色橙色+1(可能正在发生，但这似乎不太可能。我尝试扩展补丁集，以包括似乎触发此更改的边缘补丁，但这不起作用。如有任何帮助解决此问题，我们将不胜感激。

好吧，问题是海龟在两个不同的过程中移动，这两个过程都在同一时间内调用。想象一下，觅食者A会这样做(你代码的精简版(：

to go
ask foragers
[ wiggle
forward 1        ; moves 1
look-for-food
...
]
tick
end

因此，A以半随机的方向前进，然后调用寻找食物程序。进一步想象一下，他们的地盘上有食物：

to look-for-food
if food > 0
[ set color orange + 1
set food food - 1
facexy nest-x nest-y
uphill-nest-scent
forward 1                ; moves again if found food
]
...
if food-quality > 0.6 and color = yellow
[ uphill-chemical
forward 3                ; potentially moves again
]
end

因此，觅食者A在顶部通过条件，改变颜色，然后向巢穴移动。此外，如果满足其他条件，它将再移动3个距离。
