Where am I going wrong with this code?
FTB Direwolf20 v 1.0.21 CC 1.57
I have a turtle mining script that I am getting an error 'attempt to call nil' on line 18:
if turtle.getFuelLevel() >= turtle.getFuelLimit() - 500 then
and cannot see what's causing it. Here's the complete code:
chestFuel = 15
fuel = 14
function CheckFuel()
if turtle.getFuelLevel() ~= 'unlimited' then
if turtle.getItemCount(fuel) == 0 then
turtle.select(chestFuel)
turtle.placeUp()
turtle.select(fuel)
turtle.suckUp()
turtle.digUp()
turtle.select(1)
end
if turtle.getFuelLevel() < 200 then
print('Current fuel lvl: ' .. turtle.getFuelLevel() .. ': Refueling...')
turtle.select(fuel)
while true do
if turtle.getFuelLevel() >= turtle.getFuelLimit() - 500 then
print('Fueled Up')
break
end
turtle.refuel()
print('Fuel lvl: ' .. turtle.getFuelLevel())
end
turtle.select(1)
end
end
end
Best Answer
to make it forward compatible you can do the following:
function getFuelLimit()
if turtle.getFuelLimit ~= nil then
return turtle.getFuelLimit()
else
return 0;
end
end
and add a check for 0 when checking the fuel against it or set your own fuel limit
