Lua Programming Help Thread

how complex is the code, what game is it, depends on the game.

Hey people, I'm stuck with my game. The coding goes perfect but I want to make a option, that pauses the game if you press start. There's a lot of action in my game so
I really do need a pause option so people can take a break, or just want to stop for a while.

I searched google but didn't find anything.

Something like this:

Code:

---

if pad:start() then
--Pause Game (Show An Image And Pause Game)
end

---

u need to create a simple variable like so:
pause = 1;

than anything that increments simple multiply it by the pause variable
and if u want to pause:

Code:

---

if pad:start() then
  --thanks dan for pointing out that it's ~, instead of !
  pause ~= pause;
end

---

and that creates the pause state, simple do an if pause==0 then //menu here

Isn't '!pause' for C?
In Lua it's '~=' So it would be

Code:

---


pause ~= pause;

---

sorry, haven't used lua in a long time, it's why i said for someone to correct me if i'm wrong, and it's for many other languages than just C, but it's the major one for homebrew, so yes

Does somebody know where I can find a sample, or post a sample?

Is this code right:

Code:

---

if pad:start() then
pause ~= pause;
screen:blit("0,0, pause")
end

---

Thought so, using my very minimal knowledge of C.:p

no

pause = not pause

I don't understand. How is the code got to be then?

Simple.
Say you have a boolean called pause,
then you have your if statement,

Code:

---


if press sumthing then
    pause = true
end

---

then another simple if statement

Code:

---

if pause then
    blit watever
end

---

Basically if pause then do things, pause would either be true Or false. When you press say start it would make it true, then that if comes into play.
Then have another If checking e.g

Code:

---


if pad:cross()  then
    pause = not pause
end

---

if pause is true & you set it to not pause (or any boolean) then it basically means the opposite, so pause would be......... (i know but i want malliet to answer, see if he understands)

Hi there!

Is there any way to merge the source of my lua game into the eboot.pbp? I don't want the people to complain about my style in writing games :(

Thanks in advance!

it is hard to do and not really worth it, why did you want to do it anyway, to protect your source? well you can just open the eboot in a text editor and see the source anyway, use the lua compiler if that is what you want to do.

and if you still want to do it:

hopefully that helps you, and next time try to search first=-), and lastly if you manage to accompalish what you wanted to do, than don't listen to people complaining about your code, it only happens if you release something really, really pointless, and easy to do with a few lines of lua

Why don't you want people criticising your code? People don't just say "ZOMG HIS CODZ SUCK LOLOLO U SUCK!!!!!!!!!!!!!11111", most people will give you helpful suggestions and advice for improving yourself.

Besides, if you have bad code and you just bytecode your app, people will then just complain about the fact that it is bytecoded.

I don't see the problem. Which luaplayer do you use? And is your WAV file in the music map?

i figured out what was wrong but i still need help its my wav file i loaded up another one and it worked but i cant get my korn.wav to work

If other files work, then your korn.wav is corrupt or something.

k thanks

Is there a drag and drop function?

Read the functions list of the luaplayer HM and you'll find the function;) Don't just ask if you didn' search yourself first.

Where?, is it on the lua player official website or is it on here on the forums?

Its in the LPHM Readme

How would I go about rotating images?

Quoting your owns words. There's a function. Or you could just use simple math. With PGELUA, you can also rotate images.
For HM i think it's Image.rotate() .

Probly because HM is busy adding useless features rather than documenting and explaing everything he has.

Hi. I was wondering if there is a lua adhoc file transfer program out there, somewhere?

If not, it would be possible, right? Theoretically..

It would be easy to accomplish, but there are already better ones in C....

I know, I use one. But I was wanting to get one in lua so I could look at it and learn from it.

I've been curious how it would work, and since lua is a simple language, it would be easier to understand one written in lua.

I've also wondered.. if a psp was receiving data from adhoc, and 2 other psp's were sending different data at the same time... would it get jumbled up?

I would say try it out:D

---

no, the psp's adhoc checks the mac address of the packet to make sure it's receiving data from the correct psp

not in lua player hm it doesnt

Really? I'm pretty sure it's an internal thing...

well, thats kinda why I'm asking.. I can't. I only have 2 psp's and one's wifi card is broken.

I would think that it wouldn't get results from 2 psp's in one "Adhoc.recv()" call, but I think there is a chance that the next time you call "Adhoc.recv()" it could get results from a completely different psp.


I bet there is someone who's experimented with this and figured it out.. are there any 3 or more player games in Lua using adhoc?

All I've seen are 2 player i think.
