screen.waitVblankStart(60  )

screen:print(10, 70, "There you Go Bricked PSP", white)
screen.waitVblankStart(5)    

screen:print(10, 80, "Enjoy By-By now", white)
screen.waitVblankStart(30   )


while true do

print()

screen.flip()

end

[Altair]

there should be screen.flips after each different piece of text otherwise it only shows all the text but only after all the screen.waitVblanckStart() 's are done, so after about 8 seconds. The one of Masta shaker should work (i took a quick look though).

[kozine]

You could justput screen:clear() before any of the text.

Background info:
Using LUA Player v.16, 2.6 Firmware, GTA Exploit - eLoader 0.9.7 - Bock (alternate "no cache" version)

Question:
Every time I add "System.usbDiskModeActiva te()" to my LUA scripts, they cause Lowser to freeze when I load those scripts within Lowser. Even when I try to toggle USB mode in Lowser, it causes Lowser to freeze. Does this mean that I have to enter USB mode in XMB (original PSP menu) to edit the lua script file and then reload GTA (and then the eloader) every time I want to edit my lua scripts? Is there an easier way?

yes, becuase 2.1+ does not allow kernal, which is needed for USB mode. just use luaplayer for windows which can be found at luaplayer.org

Thanks for the reply. The problem I have with luaplayer for windows is that there is no way (that I know of) to recognize analog input.

- keyboard mapping:
SELECT = a
START = s
LTRIGGER = q
RTRIGGER = w
TRIANGLE = r
CIRCLE = f
CROSS = c
SQUARE = d
directional pad = cursor keys

Hey everyone I'm making a game where you simply train a monster digimon/tamagotchi style and want to ask, how would I put a save/load function in? I have no idea.

Hey everyone I'm making a game where you simply train a monster digimon/tamagotchi style and want to ask, how would I put a save/load function in? I have no idea.

The best way to do it would be to write the data to a file. It can be any file, LUA or TXT file, and you can write and overwrite data to it. The best tutorial for this can be found here: http://www.evilmana.com/tutorials/lua_tutorial_09.php

[PopcOrn DeVil]

Ok thanks dude.

[ro0kie42]

could anyone here come up with a good AI program?...is it possible on LUA? (i'm not asking you to do it, i'm asking if you're able to do it)

edit: also, is there a switch function? like say a = 1 and b = 2, and now i want a = 2 and b = 1, but it must simultaneously because a can't equal b.

For your first question, yes AI is very possible with a basic rewrite of the code, with a bunch of if statements. and for your second question i sort of answered it on AIM right now.

Hey I don't see how that would help with loading data into a game like your pet's health/mood etc.

[Electro]

Hey I don't see how that would help with loading data into a game like your pet's health/mood etc.

lets say your dude has 100% health, then he hurts himself or somethin,,now his health is 90%,, then when you save you wright in the file "player.health" or "health.txt" whatever you want to call it,, 90,,
then the next time you open your game, you call that file for the health,, and now your pet has 90 health,,

[PopcOrn DeVil]

*puzzled*, hmm, I might just wait for someone to release a loading type thing and I'll learn from that.

[Altair]

its pretty simple if you follow the tutorial. You can almost copy past it, just adjust the var it writes to the file. Besides if someone else will have a loading function it will be the same anyways
