设定乌龟能量在不同区域以不同方式减少

Question

在NetLogo中，我有三个区域：

to setup-patches

ask patches [ if pxcor > 6   
    [set pcolor yellow
    ]
  ]
  ask patches [ if pxcor <= 6
    [set pcolor green
    ]
  ]
    ask patches [ if pxcor < -6
    [set pcolor blue
    ]
  ]
end

我希望我的3种不同种类的海龟中有2种在其中一个区域（例如ycor > 6）活动时更快地失去能量。

set energy energy - 1 [ -6 if xcor <= 6]

但这并不奏效。

Answer 1

尝试：

ask patches with [pxcor > 6] [set pcolor yellow]
ask patches with [pxcor <= 6] [set pcolor green]
ask patches with [pxcolor < -6] [set pcolor blue]

那么，如果能量是乌龟的变量。

ask turtles 
[
   if yellow = pcolor [set energy energy - 1]
   if green = pcolor [set energy energy - 2]
   if blue = pcolor [set energy energy - 3]
]
