注意,在函数step中 # f3 P9 a- [" q" B0 k public def step(infrastructuredemo.GasNode watchedAgent) {- Y. X( S5 d3 V) t
//这里是watchedAgent4 i5 _8 @5 p @ T
但是在语句中,你填的是watchedNode 1 e9 |6 S7 S6 M0 [( k // This is an agent decision. " l2 s/ m( j6 x5 s& S if (watchedNode.pressure<200) { ! I- y1 U m) o setPressure(watchedAgent.pressure)- y- X5 H4 t" a. S9 B
变量名称须统一,可以都改为watchedAgent
