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. 9 N& Q- s" O K" p4 F% q: M7 x! K# Q) A2 X; k# x2 t/ O7 Y5 j/ p
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 ?' X6 T) Z8 f4 E, G5 N: m- V

请指点
