OK , maybe some ppl are gonna find me anoying but no one is ever answering this is my code:

if pad:cross() and oldpad:cross() ~= pad:cross() and Command == 1 then
Select:play() Drawcard = 1
end

if Drawcard == 1 then
drawCard() Points = Points + Pointstwo
end

but my prob is how do i make an other command next time i press it like this:

if pad:cross() and oldpad:cross() ~= pad:cross() and Command == 1 then
Select:play() Drawcard = 2
end

if Drawcard == 2 then
drawCardthree() Points = Points + Pointstwo + Pointsthree
end

I wounld be glad if somone help's ME.

you could make a integer:

a = 0

then do:

if pad:cross() and oldpad:cross() ~= pad:cross() and Command == 1 then
a = a+1
Select:play() Drawcard = a
end

so then "a" will be 2. and so on.

im not 100% that will work, but it should

[ZereoX]

Tkz il try later on.

Other question how do i make a screenshot whit WindowsLUAplayer?

[TheMarioKarters]

Yeah, Grimfate126, that would work.

With the windows one, use this:

screen:save("screenshot.tga")

Or I think it could be done like this also:

if pad:cross() then
screen:save("screenshot.tga")
end

Then just open up the screenshot in paint. And I also think you could put .png if you dont like .tga
EDIT-Thanks monotrob!

u can use tga?? i use .png

[PSPduh]

I just edited it. :) Yea because in the luaplayer windows, if you open up the test, then scroll all the way down to the bottom of it, it has that line. Plus it comes bundled with the screenshot.tga of the test program.

cool, i didnt kno that.:) i dunt use it anyway.

p.s. 700th post. yay!!!

[ZereoX]

TKz work il use png next time

[Grimfate126]

TKz work il use png next time

does the code work??or have u not tried it yet?

[TheMarioKarters]

Yeah, png is better than tga.

[ZereoX]

grim when i start my game the 3 card's are already on the table i don't even have to press x. big prob.

can u pm me your whole code? im confused.

Nope there aren't any "label" and "goto" commands. I was looking for those too at first, but you'll have to do with functions. Works just as good.

Thanks :) Guess the loops will get quite big, but the PSP is fast enough for that :Jump:

[EminentJonFrost]

ZereoX, if youre using notepad, then you can do this.

In notepad, while editing your script, press CTRL and F.

Then search for ALL your function's names.

Look for any stray functions you called outside of an 'if' statement.

If that doesnt work. Post all your code again, except put all your functions in bold. It makes looking for errors or hiccups easier. :icon_smil Heck, doing that, you might find the problem.

EDIT - Oh yea, and what does "Command" equal in the beginning when you start?

[TeamOverload]

Does anyone know where I can find a tutorial on sidescrolling. I am going to create one for psp-programming, however I need something to reference.

[Gutya]

It wouldn't really be your tut then would it? :S

[TeamOverload]

IM not using the whole thing, just need some for reference, and dont worry I will give credit

[Gutya]

Well there are not any that i know of.

[TeamOverload]

Well then I guess I might just have to right the whole thing on my own from scratch, lol.

[Gutya]

Well it will help alot of people, when i get time i'll write up some tutorials for that site.

[TeamOverload]

Ya I know, but I definately dont know everything there is about sidescrolling

[Gutya]

Well maybe you should write one when you get more experience.

[HaxxBlaster]

If a value is nil, and i would like to skip it.
Like a picture blit, likte this:

if LoadLastSave == true then
screen:blit(35, 117, LastSave, 0, 0, 238, 107, 0)
elseif return false then
screen:print(35, 117,"Coulden't load: " ..Name, black)
end

Is there any way to make this work?

how about:

if LoadLastSave == true then
screen:blit(35, 117, LastSave, 0, 0, 238, 107, 0)
elseif LoadLastSave == false then
screen:print(35, 117,"Coulden't load: " ..Name, black)
end

that should work

[HaxxBlaster]

You don't even know the rest of the code.

If i should have it like that, i have to have another "retrun if false"
to check if it's not able to show, oterwise it will load it stright.

For people to help you, you have to tell them everything you believe they should know. :)

As for the extra "return if false" code. Why not put it?

[HaxxBlaster]

I am just asking if there is a "return" command that really works, i know everything else.

I am asking for commands, not code.

[EminentJonFrost]

I'm sorry to say I dont know..
