Lua Programming Help Thread

..............

I am sorry to say that this one doent even display the text... i have noticed in whitehawks tutorial that he did it, so i am going to try and recreate that effect.

Code:

---

board = Image.load("boardnew.png")
screen:blit(0, 0, board, false)
black = Color.new(0, 0, 0)
screen:print(200, 130, "Board", black)
screen.flip()
while true do
screen.waitVblankStart()

end

---

Sorry, I hadnt even tried what I told you to do. The above WILL work. I tested it :)


My excuse is that I'm not well. And so thats why what I told you to do was wrong :D

Thanks! It works perfectly! :icon_smil

I've commeted your program to help you find out why it was doing what it was doing..

well more troubles sadly :cry:

Lua will only load the first part of my script, which displays text... It wont load any thing after that.

Code:

---

black = Color.new(0, 0, 0)
screen:print(200, 130, "Board", black)
screen.flip()
while true do              -- your program hangs here
screen.waitVblankStart()  -- because this is going to loop
end                      -- forever since true is always true

board = Image.load("boardnew.png")
screen:blit(0, 0, board, false) -- putting the picture over your text is going to erase the text. Maybe print the board first, then the text
screen:flip()
while true do
screen:waitVblankStart()
end

How can I make something where the user enters text? Like on the PSP when you click on a text box the dialog comes up that has the letters and numbers like on a cell phone. Is there a way to get that?

PLEASE PLEASE PLEASE EMAIL ME!!!!!!

Wow that took me a while...
Ok put keyboard.lua (rename it to that) in the same file as your main code.
Then put this in your main code:

Code:

---

dofile("keyboard.lua")

---

When you want define a variable or print something you can define the variable or what it's printing as keyboard()

Code:

---

-- Examples
print(keyboard())
thetext = keyboard()

---

This will allow you to input what it is going to register the value as.

=================
Start - Enter Value
D-pad - select key
R - Space
L - Delete
Select - Like holding down shift
Control pad - Press the button corresponding with the character on the selected key
================

I've tested it and it seems to work on luaplayer v9 but not v11

I'm having a bit of trouble with the Timer function.

Using this as code:

Code:

---

Timer = Timer.new(0)

---

I get:

Code:

---

error: DEFUSE.LUA:27: attempt to index global 'Timer' (a nil value)
Error: No script file found.

Press start to restart

---

Thanks in advance for any help.

It's Timer:new(0)
You have to use a colon.
