Hello,

since I am a noob at lua and I suck at error fixing, I was hoping for someone a bit more experienced to help me with an error I keep getting. I'm trying to make a simple 'shooter'-ish game (like Space Invaders but simpler). So far I've got the key-handling code and the 'ship-drawing code':

local w,h = term.getSize()
local pos = 1
function handleKeys()
  local type,key = os.pullEvent()
  if key == 203 then
	  if pos > 2 then
		pos = pos-1
	  end
	end

	if key == 205 then
	  if pos < (w-2) then
		pos = pos+1
	  end
	 end
end
funtion drawShip()
  term.setCursorPos((pos,h)
  write(" | nooo") -- not 'noooo' but <newline>ooo (it should represent a simple shooter thingy)
end
while true do
  term.clear()
  handleKeys()
  drawShip()
end

Sorry for the potential noobieness, I tried my best />

When I try to run this code/program/derp, the console throws the following error:
bios:328: [string "shooter"]:20: '=' expected -- (the program's name is 'shooter' by the way)

I can't seem to find the solution to this, so I'm hoping anyone can help me.

Thanks in advance!

Nevermind, I think I am going to study Lua for the next 10 years so I'll be able to program a decent application or game.

You've got an extra open parense ( ( ) in there. At term.setCursorPos().

Common bug. I find myself having a similar problem . . . well, a lot of the time.

I removed it and it didn't help, it still gave the same error. Thanks anyway />

After reviewing, I come with another possible fix.
This one I don't know to be the case, but I'm pretty sure it is. write needs to be called from its target. ie mon.write(), or in your case term.write(). Probably because of that very difference.

On the other hand, print does not need such a call (because I'm fairly sure it's in the os api).

Funtion should be function. Also, if you don't post the exact code with the same number of lines (yours seems to be missing three or so), it's much harder for us to find the error by line number.

Thanks for the help. I already warned you for the noobieness and while posting the code it kinda got screwed up -,-

Again, thanks, I'll try it out as soon as I'm home
