注意,在函数step中 9 @2 l; h y) t public def step(infrastructuredemo.GasNode watchedAgent) { 7 T) h% `) f/ Y6 d: B8 T8 ] //这里是watchedAgent. } t- ~7 u7 o
但是在语句中,你填的是watchedNode S5 a/ `3 D' G1 b% W4 g8 y // This is an agent decision. 1 ~- h( B; h N1 Z4 w if (watchedNode.pressure<200) { $ L, @# |# o; P3 T$ G/ a. f setPressure(watchedAgent.pressure)/ f7 }; o' d2 ~6 D( O
变量名称须统一,可以都改为watchedAgent
