Ok, I see. Thanks. Packets is too hard for me... I'll try to get decision by plugin.

Actually, I want to know, how to get handle left-click-air-event, too? Is anybody know how to do this?

This is my blocks. I want to merge #2 and #8, #3 and #9, #4 and #5 and #6 and #7 blocks. I mean, it'll be new blocks, that'll be rotate its upper texture due to yaw of player who placed this blocks. Please, learn me, how to do it?
