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. , k7 `; {& x5 U, t, b0 @ + [. x- x+ {- z; K% w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 ？ 3 }& k2 W9 M1 V1 e: w1 p( ?# t. v1 n" v' h) d M% h% g
请指点
