Maybe because computer craft has it and everyone is " abusing" it. The mod author wanted the cost to be inside the need to program it your self but because you can so easily share scripts that "cost" is gone and as a result computercraft is now seen by many players as an overpowered mod. Maybe the mod author of steves factory manager doesn't want the same thing to happen with his mod. However I never used this mod so I am not certain how the sharing in stead of making the scripts would effect the balance.
computercraft is over powered?
I love turtles. In fact I have been looking into sentry programs for battle turtles. I found out I can dye them... I'll have 4 for the base, blue, orange, red and purple. Yes my computercraft battle turtles...
Seriously though, it's not that it's difficult to setup really each time but it can get tedious if you are programming the same thing. Discovering new things and programming them is fun. But after the 3rd or 4th time...
Ok I guess where the frustration is where I move my base at all... If I have to move the factory manager I have to completely reprogram it. How about a save function for the just that minecraft world so I can move the block.... No export... is that a cfg option as well? I would love to see that button (Save upon breaking) upper right hand corner...
