PLZ help! all i want is to know how to move on to a new question if the question before that was answered correct?!?!?! can some1 plz help me?????

---

u could have a function for each question. like:

Code:

---

function questionOne()

-- your question code--

---

THEN u could make a variable like:

Code:

---

questionanswered = false

---

then, when the person preses up down, or whatever, u put:

Code:

---

questionanswered = true

---

and then put:

Code:

---

if questionanswered == true then
function questionTwo()
end

---

where function questionTwo() is your second question... and so on.

hope i helped:)

bronxbomber, the best way to do this is using arrays. The following example will proceed to the next question if correct and go back to question 1 if incorrect:

Code:

---

green = Color.new(0, 255, 0)
black = Color.new(0, 0, 0)
red = Color.new(255, 0, 0)
blue = Color.new(0, 0, 255)
white = Color.new(255, 255, 255)

totalquestions=1

questions = {}
answerOne = {}
answerTwo = {}
answerThree = {}
answerFour = {}
correctanswer = {}
questions[1] = "Who hit the most homeruns ever?"
answerOne[1] = "down = Babe Ruth"
answerTwo[1] = "right = Hank Aaron"
answerThree[1] = "left = Barry Bond"
answerFour[1] = "up = Sammy Sosa"
correctanswer[1]=2

i=1
while i<=totalquestions do
    screen:clear()
    screen:print(80, 100, questions[i], blue)
    screen:print(150, 200, answerOne[i], white)
    screen:print(150, 215, answerTwo[i], white)
    screen:print(150, 230, answerThree[i], white)
    screen:print(150, 245, answerFour[i], white)
    inputreceived=0
    screen.flip()
    screen.waitVblankStart()
    while inputreceived==0 do
        pad = Controls.read()

        if pad:down() then
          screen.flip()
          if correctanswer[i]==1 then
              screen:print(150, 110, "You're Correct!", green)
          else
              screen:print(150, 110, "Sorry, incorrect.", red)
              i=0
          end
          inputreceived=1
        end
       
        if pad:right() then
          screen.flip()
          if correctanswer[i]==2 then
              screen:print(150, 110, "You're Correct!", green)
          else
              screen:print(150, 110, "Sorry, incorrect.", red)
              i=0
          end
          inputreceived=1
        end
       
        if pad:left() then
          screen.flip()
          if correctanswer[i]==3 then
              screen:print(150, 110, "You're Correct!", green)
          else
              screen:print(150, 110, "Sorry, incorrect.", red)
              i=0
          end
          inputreceived=1
        end
       
        if pad:up() then
          screen.flip()
          if correctanswer[i]==4 then
              screen:print(150, 110, "You're Correct!", green)
          else
              screen:print(150, 110, "Sorry, incorrect.", red)
              i=0
          end
          inputreceived=1
        end
    end
    i = i+1
    screen.flip()
    screen.waitVblankStart(120)
end

Edit: Edited so that there's a 2-second delay before loading the next question, allowing for seeing whether the answer was right or not.

Edit again: I have no idea why that huge space is showing up between "12" and "0"

Edit again: Forgot to initialize the arrays.

youd say something like:
-- top of the script

movehello = true


if movehello == true then
letterPosx = letterPosx + 2 end
screen:print(letterPosx, letterPosy, "HELLO", blue)
screen.waitVblankstart(50 )
movehello = false
end

---

Code:

---

letterPos = {}
letterPosx = 200
letterPosy = 100

while true do
blue = Color.new(0,200,350)
movehello = true
screen:clear()
pad = Controls.read()


if movehello == true then letterPosx = letterPosx + 2 end
screen:print(letterPosx, letterPosy, "HELLO", blue)
screen.waitVblankStart(50)
movehello = false


if pad:select() then
break
end
 
screen.flip()
screen.waitVblankStart()
 
end

---

1st it takes the 50 to appear the word, 2nd it takes 50 to move each 2 pixel.
the thing is that "screen.waitVblankStart(5 0)" work for the word and the false , is there a way to make "screen.waitVblankStart(5 0)" separate from the HELLo word and Work only for the False ?
can you correct it please? so it starts normally and stops at 50

Guys i have a question: there is a kinda of a circle object, but the hole image is a square, the white is outside of the circle and blue is inside the circle. I saw some pictures that is a circle ones, and the outside of the circle have a color to make it invisivel (like make the outside bellow of any picture that comes), so other colors can go above it and repleace the white with other picture above it
. what could the Hue, Sat, Lum, Red, Green, Blue could be ?

ok i ask if is posible to make 2 buttons make one fuction ..... example press cross and square at the same time and that will make a break or do something ... like on umd loadder

I want to know that!!!!!!!!

I want to know that!!!!!!!!

Yes...it's really easy....

Code:

---

pad=Controls.read()
if pad:cross() and pad:circle() then
do something
end

---

That will make it so that if X and O are pressed at the same time, and ONLY if they are pressed at the same time, it will do something. It works with any button combnation and also with more than 2 buttons. For example:

Code:

---

pad=Controls.read()
if pad:cross() and pad:circle() and pad:square() and pad:triangle() and pad:up() and pad:down() and pad:left() and pad:right() and pad:l() and pad:r() and pad:start() then
do something
end

---

also works.
