what is the code to exit back to luaplayer

[TacticalPenguin]

Thisll make it exit back to luaplayer when you place it in your main loop and press start:

if pad:start() then
break
end

Also you must be in your index.lua for that to work, not in a game.lua or other already dofiled file.

that gives a NULL error. and if its above the loop it says no loop to break end

[TacticalPenguin]

It has to be in your loop because its BREAKing your loop. And all you need to do is between the last bit of your code and screen.waitVblankStart() screen.flip() end add in:
if pad:start() then
break
end

If it gives you a null then it means you havent defined pad = Controls.read()

[Cheez Pirate]

that works, thanks :)

[TacticalPenguin]

Youre welcome

[Cheez Pirate]

ok. it says null still and after about 1 or 2 seconds it will reset. is there any way to keep it from sayin that.

System.usbDiskModeActivat e()
white = Color.new(255,255,255)
menuBackground = Image.load("menuBackgroun d.png")
while true do
pad = Controls.read()
screen:blit(0,0,menuBackg round)
screen.flip()
screen.waitVblankStart()
if pad:start() then
break
end
end

screen.flip()
screen.waitVblankStart()

end
end

Try changing your code to this:

System.usbDiskModeActivate()

white = Color.new(255,255,255)
menuBackground = Image.load("menuBackground.png")

while true do
screen:blit(0,0,menuBackground, false)
pad = Controls.read()
if pad:start() then
break
end

screen.waitVblankStart()
screen.flip()
end

[TacticalPenguin]

Yea you need to put it before the watvblank and flip. Nothing should go between screen.waitVblankStart() screen.flip() and end except for variable concerning stuff like oldpad = pad.

I wanna try and incorporate a small little animation to my charcter in my lua app . How would i go about saying when pad is held on left and then play the animation ?

[FreePlay]

What?

[eldiablov]

I want my player to do a certain action when i double tap left on the d-pad. How would i go about doing this ?

[yaustar]

Set a tick count or timer in the game, get the current tick count or value of the timer when you first tap left, then get it again when you tap left again. Check the difference of the values and if it is less then a certain value, perform the action.

Also you have to be able to detect the difference between a tap and when a direction is held down.

There's a pre-made keyboard in the download section. I think it's called Danzeff's OSK or something.

[MSeven]

but thats for C i was just looking at that

[TeamOverload]

but thats for C i was just looking at that

I haven't checked this out, but it says it's for Lua: http://ps2dev.org/news/Danzeff_keybo...PSP_Lua_Player

[MSeven]

Being as experienced as you say you are, you should be able to do that. At least with help from the instructions.

Well, I thought he had enough experience. After all, he made Text2Phone and fBrowser.

[gameo]

Well... I just started at LUA, and i followed whitehawk's turtorial at
psp-programming.com

So what now? I only know how to make a loading screen, and load screenshots. EDIT: Also load sounds.

EDIT: (I'm currently using Luaplayer 19 and script.lua file.)

I don't even know how to move an object if i want to make a ping pong game.

I someone could give me a link, or help me on MSN, that would be much appreciated.

[eldiablov]

Gameo i'll help

looks like it's tutorial time. Where should i go ?

[Anti-QuickJay]

Wow, Thats it? Loading media isnt really hard, Just one line.....

[eldiablov]

Any links to the tutorial about animating your player when holding or double tapping a button. I really need a step by step. It's hard having no knowledge in Lua
