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
% \/ \- L1 i- L+ Y       public def step(infrastructuredemo.GasNode watchedAgent) {
; y/ M: F" m4 z& P         //这里是watchedAgent! \$ V( ^* v, y
但是在语句中,你填的是watchedNode
7 C1 ?7 R! ~7 I/ S. P        // This is an agent decision.4 e5 @/ c% v" P: O( _# C3 p, c
        if (watchedNode.pressure<200) {  
/ T( c% {' G5 Z) w            setPressure(watchedAgent.pressure)7 R8 L/ {  `7 ]! u
变量名称须统一,可以都改为watchedAgent
