在netlogo中動態更改rgb

Question

因此，我在網絡標誌中編寫了一個簡短的程序，我想根據他們自己擁有的變量view對我的海龜進行顏色編碼。我試圖在netlogo中使用color-scale定義顏色，但它不完全符合我的要求。

我寫了這個來描述我想要的，但是當我將col變量傳遞給set color命令時，netlogo似乎會感到困惑。

to colorise;;------------------------------------------------------------ 
; this changes the agent's colour based on their current [view] score. 
; We could use the color-scale in netlogo, but it only works for one colour 
; and it's easy to end up with a colour so dark we can't see it against black patches. 

    moderate ; resets any agents which have somehow ended up with a view score outside -1 to +1 
    ifelse view > 0 
    [ let col (1 - view) 
    set col col * 255 
    set color [ 255 col col ] 
    ] 
    [ let col (1 + view) 
    set col col * 255 
    set color [ col col 255 ] 
     ] 

end 

沒有人有任何想法嗎？

謝謝！

假設你已經正確地有限的角度範圍內，你會正好碰上列表創建問題：你不能用變量使用括號標記。相反，嘗試

set color (list col col 255)
