to get a turtle reading the right GPS position you need to setup a GPS host system with 4 computers, like this http://www.computerc...osition-system/
To do this on every world could be a lot of work.
So i' ve made a little program, that build a satelite system in 100 meter height.
Program needs to be started with x,y,z coordinates and facing of the turtle. Then simply follow the instructions to fill the slots.
Hope it's usefull.
local tArgs = { ... } if #tArgs < 4 then print("Usage : satelite <x> <y> <z> <f>") return end local Xpos = tonumber(tArgs[1]) local Ypos = tonumber(tArgs[2]) local Zpos = tonumber(tArgs[3]) local facing = tonumber(tArgs[4]) function buildUp(floppySlot) -- Put the disk drive turtle.select(3) turtle.place() -- Load disk into drive and write startup file turtle.select(floppySlot) turtle.drop() file = fs.open("disk/startup","w") file.writeLine("shell.run(\"gps\",\"host\","..Xpos..","..Ypos..","..Zpos..")") file.close() -- put the computer turtle.up() turtle.select(2) turtle.place() -- place the modem turtle.up() turtle.up() turtle.forward() turtle.select(4) turtle.placeDown() turtle.back() turtle.down() turtle.down() -- turn computer on computer = peripheral.wrap("front") sleep(0.5) if computer then computer.turnOn() end turtle.down() end if type(Xpos) ~= "number" then print("x must be number") return end if type(Ypos) ~= "number" then print("y must be number") return end if type(Zpos) ~= "number" then print("z must be number") return end if type(facing) ~= "number" then print("facing must be number") return end print("Please fill up following slots") print("1 = Fuel") print("2 = Computer (4x)") print("3 = Disk drive (4x)") print("4 = Modem (4x)") print("5 - 8 = Floppy disk (4x)") print("Press any key to continue") while true do event, param1 = os.pullEvent() if event == "char" then break end end while turtle.getItemCount(1) > 0 do turtle.refuel() end print("Fuel level is "..turtle.getFuelLevel()) print("Going up to 100 meter to build satelite") for height = 1, 100, 1 do turtle.up() end Ypos = Ypos + 101 -- Go 10 forward to set the first computer for c = 1, 10, 1 do turtle.forward() end if facing == 0 then Zpos = Zpos + 11 end if facing == 2 then Zpos = Zpos - 11 end if facing == 1 then Xpos = Xpos - 11 end if facing == 3 then Xpos = Xpos + 11 end buildUp(5) -- Go back 20 and put the second computer turtle.turnRight() turtle.turnRight() if facing == 0 then facing = 2 elseif facing == 1 then facing = 3 elseif facing == 2 then facing = 0 elseif facing == 3 then facing = 1 end for c = 1, 20, 1 do turtle.forward() end if facing == 0 then Zpos = Zpos + 22 end if facing == 2 then Zpos = Zpos - 22 end if facing == 1 then Xpos = Xpos - 22 end if facing == 3 then Xpos = Xpos + 22 end buildUp(6) -- go 10 forward to the middle turtle.turnRight() turtle.turnRight() if facing == 0 then facing = 2 elseif facing == 1 then facing = 3 elseif facing == 2 then facing = 0 elseif facing == 3 then facing = 1 end for c = 1, 10, 1 do turtle.forward() end if facing == 0 then Zpos = Zpos + 11 end if facing == 2 then Zpos = Zpos - 11 end if facing == 1 then Xpos = Xpos - 11 end if facing == 3 then Xpos = Xpos + 11 end -- and 10 more up for c = 1, 10, 1 do turtle.up() end Ypos = Ypos + 10 -- turn 90 degree to setup the second row turtle.turnRight() facing = facing + 1 if facing == 4 then facing = 0 end -- Go 10 forward to set the third computer for c = 1, 10, 1 do turtle.forward() end if facing == 0 then Zpos = Zpos + 11 end if facing == 2 then Zpos = Zpos - 11 end if facing == 1 then Xpos = Xpos - 11 end if facing == 3 then Xpos = Xpos + 11 end buildUp(7) -- Go back 20 and put the last computer turtle.turnRight() turtle.turnRight() if facing == 0 then facing = 2 elseif facing == 1 then facing = 3 elseif facing == 2 then facing = 0 elseif facing == 3 then facing = 1 end for c = 1, 20, 1 do turtle.forward() end if facing == 0 then Zpos = Zpos + 22 end if facing == 2 then Zpos = Zpos - 22 end if facing == 1 then Xpos = Xpos - 22 end if facing == 3 then Xpos = Xpos + 22 end buildUp(8) -- go 10 forward to the middle turtle.turnRight() turtle.turnRight() for c = 1, 10, 1 do turtle.forward() end -- and back to earth while not turtle.detectDown() do turtle.down() end
