redstone i/o

加入了T触发器方块:收到红石信号时改变状态,这个过程能被侦测器检测到(妈妈再也不用担心我用发射器加细雪桶,粘贴原理图的时候发现细雪桶不见了)

Added T-trigger cube: change state when receiving a redstone signal, this process can be detected by the detector (mom won't have to worry about me using a transmitter to add a snow bucket, and then find out that the snow bucket is missing when I paste the schematic).
