Im making a program that needs to listen to multiple events so os.pullEvent("char") wont work...and i need to be able to turn keycodes into chars because for some reason the "char" event is never fired when i press a key
I have also tried string.char(p1) but i guess the mc keycodes are different to lua ones because it never returns the right value
Please help!

Yes the ASCII char set has different numbers to the keyboard key bindings of LWJGL... You should be able to use keys.getName( keycode ) ... However this will also return things like "CTRL" for other keys just not char... There must be some reason why the char event isn't working, can you show us the relevant code please?

its about 1000 lines spread across 5 programs...so i cant really show code...but i use a program that sleeps between os.pullEvent() so if char and key is fired next to eachother it might not pick up the char
edit: thanks for the help...keys.getName(p1) works

[theoriginalbit]

can't even show the main loop where you are trying to read the char/key?

ahhh your using sleep... thats eats events... meaning your program will sometimes miss some, you should avoid sleeps when using an event loop and instead use timers ( which is how sleep works anyways )...

[Exerro]

oh yeah re-read my code it starts a timer and does os.pullEvent() but if a key is repeatedly pressed it would bypass this so it sleeps if it wasnt the timer that triggered the event...
and the input code:

function sky.input(event,p1,p2,p3,p4,p5)
if event == "key" and p1 == 14 then
  sky.event.queue("fquit","done")

  data[p3][p2][1] = p2
