Hi.
I want to port a game to corona, but I’m very confused.
The game presents a start menu with some graphics, level select (+ button, - button), an exit button and a start button.
How to structure that?
I made something like that:
main.lua
=======
–initiate global variables
level=1
stay=1
…
function startmenu()
local buttonstart=nil
local buttonexit=nil
local buttonminus = display.newImage(“buttonminus.png”)
buttonminus.x = -500
buttonminus.y = 410
local buttonplus = display.newImage(“buttonplus.png”)
buttonplus.x = -500
buttonplus.y = 410
local function drawmenu()
local filepng=“txt”
local dig1=0
local dig2=0
– display backgroun image
display.newImage(“background.png”,0,0)
– display game title
display.newImage(“title.png”, (largura - 540)/2, 20)
— display the “LEVEL” word
display.newImage(“txtlevel.png”,80,370)
– display exit button
buttonexit=display.newImage(“buttonexit.png”,782,0)
— display level digits
if level<10 then
filepng = “txt” … level … “.png”
display.newImage(filepng, 320, 370)
else
dig1=math.floor(level/10)
dig2=level - (10*dig1)
filepng = “txt” … dig1 … “.png”
display.newImage(filepng, 320, 370)
filepng = “txt” … dig2 … “.png”
display.newImage(filepng, 356, 370)
end
— draw minus level button, if level > 1
if nivel>1 then
buttonminus.x=45
else
buttonminus.x=-500
end
– draw plus level button, if level < 20 (there are 20 level in the game, 20 is the last level)
if nivel<20 then
if nivel<10 then
– if there are only 1 digit in level number
buttonplus.x=399
else
– if there are 2 digit in level number
buttonplus.x=435
end
else
– positionate out of screen if level=20 (last), so don’t use
buttonplus.x=-500
end
--display start button
buttonstart=display.newImage(“botstart.png”,147,270)
end
drawmenu()
local function levelminus()
level=level-1
drawmenu()
return true
end
local function levelplus()
level=level+1
drawmenu()
return true
end
local function startbut()
stay=0
return true
end
if level>1 then
buttonminus:addEventListener( “tap”, levelminus )
end
if nivel<20 then
buttonplus:addEventListener( “tap”, levelplus )
end
buttonstart:addEventListener( “tap”, startbut )
end
startmenu()
if stay=0 then
– go to game itself
end
====================
so…
This is the correct structure?
when I press the start button, I want to exit startmenu and go to another new thing - the game itself, so how do I cancel the evenListerners and remove everything?
Anyway, the starmenu does not show the buttonminus and buttonplus. Why?
And if I write something in the “if stay=0 then” near to end of main.lua, like display.newImage(“something.png”,0,0)
and press the start button, so --> the variable stay will be 0. but the code doesn’t run, and it does not show the image something.png.
I made that thing to test if when I press start button, I could go to another thing… the game itself.
PLEASE help me
