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) {
$ [) t# t7 v, e2 a) T4 i         //这里是watchedAgent
但是在语句中，你填的是watchedNode
        // This is an agent decision.

            setPressure(watchedAgent.pressure)
8 `# t# o, r! n) {变量名称须统一，可以都改为watchedAgent
