报错信息有吗？请标出来。我好像碰到过，删除了哪条语句就行了。

报错信息发一下看看

注意，在函数step中
       public def step(infrastructuredemo.GasNode watchedAgent) {
         //这里是watchedAgent
1 H! n% Y! V* i* w 但是在语句中，你填的是watchedNode
. f$ g6 C* P% U        // This is an agent decision.
  S$ S$ [) A$ {+ ?4 b( P$ I+ U# b        if (watchedNode.pressure<200) {  
            setPressure(watchedAgent.pressure)
变量名称须统一，可以都改为watchedAgent
