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。

注意,在函数step中: m/ n) B$ x) C. z# X& x
       public def step(infrastructuredemo.GasNode watchedAgent) {
8 }6 f  `1 V5 ~: Y* h2 Q: m         //这里是watchedAgent* ^" J) `2 s0 k- @) i( C% v% N
但是在语句中,你填的是watchedNode# E6 u' m& L3 N) Q- p
        // This is an agent decision.) h- O2 M" Y1 f2 s/ q
        if (watchedNode.pressure<200) {  , W! m( ^4 g# D; n  ~$ @
            setPressure(watchedAgent.pressure). x; o* ?( J" j
变量名称须统一,可以都改为watchedAgent
