如题,我看了transport block 的demand connector 的使用说明:Demand: If the demand connector is connected the block will only accept items if the value at the demand connector is greater then the current number of items being transported. % s% a* n8 U/ y+ a- T2 ` 0 ?5 L$ v7 |. o5 c7 o是不是说现在我transport block 正在transport 4个items,我的demand connector 输入值要大于4,比如说5之类的才能使得transport block接受我的这5个小球;反之,要是 输入值要小于4,比如2,它就必须累积到5才能走进transport block ? / R6 ]' l, c# d+ M' {4 ~+ z: M0 r2 C( Y+ U2 u, j: C
请指点
