询问 Buteo-platypterus [ 面向 min-one-of patches with [pcolor = green ] [distance myself] 如果 distance patches with [pcolor = green] < 5 [fd 1] [fd 5 set energia energia - 5] ]

答案1

得分: 2

ifelse distance patches with [pcolor = green][...]
这行代码是你的问题。你正在询问到所有绿色斑块的距离，而不是到最近的绿色斑块。

ifelse distance min-one-of patches with [pcolor = green] [distance myself] [...]
这应该解决问题。你还可以使用一个本地变量，以免一遍又一遍地重写相同的代码（这可能导致错误）。

   let destination min-one-of patches with [pcolor = green ] [distance myself] 
   face destination 
   ifelse distance destination < 5 [fd 1][ fd 5 set energia energia - 5] 
]```

`ifelse distance patches with [pcolor = green][...]`
This line of code is your problem. You are asking the distance to all green patches, an agentsent, instead of to the closest green patch. 

    

    ifelse distance min-one-of patches with [pcolor = green] [distance myself] [...]

This should solve the problem. You could also use a local variable to not have to rewrite the same code over and over again (which can lead to mistakes)

    ask Buteo-platypterus [ 
       let destination min-one-of patches with [pcolor = green ] [distance myself] 
       face destination 
       ifelse distance destination &lt; 5 [fd 1][ fd 5 set energia energia - 5] 
    ]
