lua programming inside the PGE

[dlevans]

i just downloaded the phoneix game engine and i was messing around with the lua scripts and i was wondering on the on screen keyboard script what would be the syntax so it would display text then have the user type something and keep going like this
hello welcome to pge lua!
enter your name:
--osk would pop up
your name is :txt:
enter your birthday:
--osk again
--calculate age
you are: X years old

also on the save data script could you save a lua script so you could keep adding to it like names or phone numbers or anything?

thanks

this would prolly get more attn in the lua programming section :)

can you move it... i dont want to double post

Moved

You would basically just repeat the OSK sample several times, once for each event.

Make an attempt at it yourself, then come back and post code if you require further help.

You can save whatever you want as savedata.

okay ill try it once i get it working ill try loading some txt off the memory stick kinda like a scheduler where the saves are your tasks for the day

okay im a little confused

-- Load the font, 16 pixels in height, to RAM

doesnt display text or text2 just keeps looping the osk with the intial text "enter second text" but no text is ever entered and the first osk never comes up i changed exit to Ltrigger and Rtrigger cuz i like pressing start on the osk and it kept exiting that works fine but it doesnt display any text at all
