NetLogo 5.3.1エラー：カメだけの理由でGET-EARLYWARNをオブザーバコンテキストで使用することはできません

Question

なぜこのエラーが発生するのか分かりません。私はget-earlywarnプロシージャに代理店を入れてみましたが、動作していないようです。それはask n-of nエージェントによって引き起こされますか？私はこれを別の手順に入れるべきですか？

Answer 1

「亀は唯一のでオブザーバーコンテキストでXXXを使用することはできません」ので、どこかのコードで、あなただけのコマンド亀を求めているあなたは、エラーコードを取得している：ここで

コードです（例：X 前方または セット年齢年齢は亀が所有している）ではなく、直接カメへ。代わりの

to go 
    fd 1 
end 

を：：私が言うgoコマンド作る場合と同様

to go 
    ask turtles [fd 1] 
end 

あなたのコードについては、何をどのようなグローバルがあるの所有者を見ずに、私は推測しているそのあなたは（GET-earlywarnて途中について）尋ねコードのビット：

ifelse reach = "REACHED" 
     [ 
     ifelse y >= 0.5 
     [ 
      store-water 
      use-storedwater   
     ].................... 

私はあなたがその時点でいずれかのエージェントにそれを求めていると思ういけません。手を差し伸べる前にエージェントに依頼すると助けになるはずです。

p.s.できるだけコード全体を渡す場合は、グローバル/ etcを含めてください。あるいは、問題を絞り込む方がはるかに優れています。

編集：はい。これでコード全体を入れました。間違いなく私が思った問題です。あなたはどんなカメにも尋ねることなく、もしかすると尋ねる。
