nice work, i cant wait for it but i just have some worries like controlling it:
1)will it be like a vehicle just vertical only?
2)will you use wrench events to tell it stop and move?
3)will it have an elevator brick that the elevator stops at?
4)will it just go to a certain hieght each time its activated?
sorry i have filled this post with things that you probably have all figured out, i was just curious i know that there can be problems in blockland with scripting when the torque engine is in use ( like building water in a confined area) but i trust you have it all worked out
