Lua Programming Help Thread

It's okay, we're all newbies when we start out.

Code:

---

white = Color.new(255,255,255)

while not pad:start() do
  pad = Controls.read()
  if pad:cross() then
      screen:print(50,60, "you pressed x, buddy", white)
  end
  if pad:circle() then
      screen:print(50,60, "that was a circle", white)
  end
  if pad:triangle() then
      screen:print(30,60, "my calculations say that you just pressed triangle", white)
  end
  if pad:square() then
      screen:print(50,60, "you're a square", white)
  end
  screen.waitVblankStart()   
  screen.flip()
  screen:clear()
end

Pad was a nil value because you didn't give it one. You have to do "pad = Controls.read()". You could also change pad to anything else, such as "input = Controls.read()", then you would check what button is being pressed with "input:circle()", for example.

If your code isn't in a loop, then LuaPlayer will go through the code once, then end the program. I set the loop to go until it detects that you are pressing the start button.

After "screen.flip()" you should put "screen:clear()" to clear the backbuffer, or else the backbuffer will have the image from the previous screen. It might help if I drew an example for you.

Tell me if you want me to explain something in more detail. It's always nice to know how things work, rather than just knowing that they do.

screen.clear()?
You mean screen:clear()

Yes, screen:clear(). >_>

Instead of "screen.flip()", you can use "screen:flip()" if you want.

This brings me to a question that I need answered: what are the meanings of ":" and "."? The fact that both "screen.flip()" and "screen:flip()" work, yet "screen.clear()" doesn't confuses me. =P

Okay, can someone help me with a startup menu. I have the background and all, but how do i make text appear, and you can select it. ALso, how can you order your script so you know what is what? Thanks, also anyone willing to teach me lua like alot of stuff, pm me! Thanks in advance!!!!

Are you planning to use images or text on the menu? For like all the options, like start game, etc. Will it be images or text?

It going to be text, kiind of like links, you know. Meaning, you go on link, start for this example, and it starts the game, etc.

Im having a problem, the code ive scripted so far works perfectly in the lua player, but once i turn it in an eboot, doing what anotehr user said to do, it doesnt do all the code. What do you think is wrong?

I can fix it, but you will have to wait until I get home. I'll fix it then. What exactly have you tried to do?

dont know who said it, but a guy said, get an eboot that is used with a lua application. I did that. Then he said open it up, the put your own icon0 etc to make it your own. I did that. I included the pictures, but the tricked out loading screen i made skipps from 0% all the way to the menu! I wonder why. BTW, when do you get back from school? Im in Florida, so i dont have to go to school because of Hurricane Wilma.

anybody know how i can create labels?

like:
lbl b
then later:
goto b
