Lua Programming Help Thread

there is one thing that i m stuck at

this is the code

Code:

---

blue=Color.new(0,153,225) 

screen:print(200, 100, "Hello!", blue)
screen:flip()

screen.waitVblankStart(30)
screen:print(200, 50, "Hello!", blue)
screen:flip()


while true do
screen.waitVblankStart()
end

---

I want to put a word with out delay, then make another word appear after like 2 second but cant figure it out =(
if i put screen:flip() 2 times, it will disable the 1st word and make the other one appear
Please Help!

Laught if you think this is noobish(I dont care) I m new using this :icon_surp but not new at making hacks for pc games

Code:

---

blue=Color.new(0,153,225)   
timer=new.Timer()

screen:print(200, 100, "Hello!", blue)
screen:flip()
timer:start()

if timer==2000 then
screen:print(200, 50, "Hello!", blue)
screen:flip()
end

while true do
screen.waitVblankStart()
end

---

For some reason the "screen.waitVblankStart(3 0)" doesn't really pause. Atleast its not working for me. Even if i put in 1 million its like there is just a "screen.waitVblankStart() "?

Not laughing at all people ask this all the time.

why wont they stay?

[edit]and i dont think its working at all cause when i press start to break the program it does nothing as well[/edit]

---

the break part when u hit start should work. i just tested it. and to make it stay make the while loop look like this

Code:

---

while true do
screen:clear()
screen:blit(0, 0, background,  false)
pad = Controls.read()

if titleNumber == 1 then
                screen:blit(0,0,titlePlay  )
        end
        if titleNumber == 2 then
                screen:blit(0,0,titleInfo  )
        end
        if titleNumber == 3 then
                screen:blit(0,0,titleExit  )
        end
        if titleNumber < 1 or titleNumber > 3 then
                screen:print(0,0,"error in titleNumber", white)

        end


if pad:start() then
        break
end
--Main Menu D-Pad Controls
if pad:right() and titleNumber < 3 then
titleNumber = titleNumber + 1
end
if pad:left() and titleNumber > 1 then
titleNumber = titleNumber - 1
end
screen.flip()
end

and get rid of the funtion for the menu

Hey guys, I got a quick question. (And, whoever helps me with this scores a cool 500 points)

I need to know more about object orientation, and maybe an example on how to use the variable "self". And whats a metatable? :confused:

Code:

---

blue=Color.new(0,200,350)     
screen:clear()
pad = Controls.read()
screen.flip()
screen:blit(90, 195, circle)
screen:print(200, 70, "Hello!", blue)
screen:flip()

if pad:cross() then
screen:blit(50, 228, x)
screen.flip()
end


while true do
screen.waitVblankStart()
end

---

Im still trying to make the text stay and make appear another one but i m stuck in there
im also stuck at trying to make the Hello appear when i press X button
Can some one help pls
The code above is what im trying to put
The lua tutorial Is a great tutorial http://www.scriptscribbler.com/psp/lua/lesson02.htm but i dint understand the part to make buttons work to appear something ( Please Help )

That code is just messed up..

put the "while true do" at the top.
And put a "screen.flip()" right after "screen.waitVblankStart() " and remove ALL the other "screen.flip()"s.

Buahahahhahahahah I love you sam Thanks so Much

the code is

Code:

---

while true do
blue=Color.new(0,200,350)     
screen:clear()
pad = Controls.read()
if pad:cross() then
screen:print(200, 70, "Hello!", blue)
end


screen.waitVblankStart()
screen.flip()
end

---

I have some questions
it only shows hello when i pres X button is there a way to freeze it when i press X button?
"pad = Controls.read()" have to be in the top of the text/Object to work? or anywhere will work ?
and another question. the while to do on the top is to make it it true ? so it shows everything ?
