Question about Developer

I'm trying to create a splash screen for my game with a a few buttons on it. I'm trying to figure out how to make my Play button take the user to the first level (aka next screen)

I'm trying to use Ricardo and Peach's example. Heres what I'm looking at:

Menu.lua

local background = display.newImage ("Splashscreen.png")
localGroup:insert(background)
--> This sets the background
 
local redbutton = display.newImage ("splashplay.png")
redbutton.x = 160
redbutton.y = 100
localGroup:insert(redbutton)
 
local bluebutton = display.newImage ("splashoptions.png")
bluebutton.x = 160
bluebutton.y = 225
localGroup:insert(bluebutton)
 
local yellowbutton = display.newImage ("splashabout.png")
yellowbutton.x = 160
yellowbutton.y = 350
localGroup:insert(yellowbutton)
--> This places our three buttons
 
local function pressRed (event)
if event.phase == "ended" then
director:changeScene ("red")
end
end
 
redbutton:addEventListener ("touch", pressRed)
 
local function pressBlue (event)
if event.phase == "ended" then
director:changeScene ("blue")
end
end
 
bluebutton:addEventListener ("touch", pressBlue)
 
local function pressYellow (event)
if event.phase == "ended" then
director:changeScene ("yellow")
end
end
 
yellowbutton:addEventListener ("touch", pressYellow)
--> This adds the functions and listeners to each button

i recommend you to download director class example

http://developer.anscamobile.com/code/director-class-10

and see how it works

actual syntax for changing scene is like,
director:changeScene("your lua file name","any effect")

when you download by above link you should have good idea

when using director, we use director:changeScene ("blue") to change the scene.

blue is actually a file residing in the same folder (blue.lua).

You don't have to make any changes to the director.lua file.
the colors specified inside director.lua file is for showing the fading effect. It got nothing to do with the colors shown when u click the button.

Thanks for the replies. Do I call the .lua from the menu.lua? I'm a newbie at this so any example would be awesome.

Thanks again,
Andrew

hope this sample will help... this was written for a fellow developer in this forum to solve a problem he was facing...

main.lua

director = require("director")
local mainGroup = display.newGroup()
mainGroup:insert(director.directorView)
director:changeScene("loadtitlescreen")

Thank you for the response.

Ok so I have:
main.lua
loadtitlescreen.lua
titlescreen.lua
gameboard.lua
director.lua

When I load main.lua in to the corona simulator I get an error message

"Director Class - ERROR"
"Director ERROR: Failed to execute function:0x19d7d5a0( params ) function on "loadtitlescreen'."

The screen is black except for the words "Go to title screen".

Getting Director to function properly seems to be my biggest hurdle. I'm really at a loss of what to do or where to go from here : (

Sorry there was a small error in loadtitlescreen.lua.
I edited something after posting and din't check whether its working or not... :)

module(..., package.seeall)
function new()
    print ("in load titlescreen file")
    local localGroup = display.newGroup()
        
    local titlescreen = display.newText("Go to title screen",75,300,nil,25)
    localGroup:insert(titlescreen)
 
 
 
    local function touched (event)
        if ("ended" == event.phase) then
                director:changeScene( "titlescreen", "fade" )   
        end     
    end
 
     titlescreen:addEventListener ("touch", touched)
 
      -- MUST return a display.newGroup()
      return localGroup
end

Thanks a million for checking back in. You really helped me out. Give yourself a pat on the back please : )

you are welcome....

I've got another question.

Here's my code for loadtitlescreen.lua

module(..., package.seeall)
function new()
    print ("in load titlescreen file")
    local localGroup = display.newGroup()
 
    
    
     local background = display.newImage("splash.png" )
    background.x = display.stageWidth / 2
    background.y = display.stageHeight / 2    
 
    
 
 
    local titlescreen = display.newText("Play Game!",175,130,nil,25)
    localGroup:insert(titlescreen)
titlescreen.x = display.stageWidth / 2
titlescreen.y = display.stageHeight / 2
 
 
 
    local function touched (event)
        if ("ended" == event.phase) then
                director:changeScene( "titlescreen", "fade" )   
        end     
    end
 
     titlescreen:addEventListener ("touch", touched)
 
      -- MUST return a display.newGroup()
      return localGroup
end

just add localGroup:insert(background) and it will be fine.

thanks again : )

I'm trying to make more groups but not having much luck, here's my code:

    local localGroup = display.newGroup()
 
 
    local titlescreen = display.newImage("Playbutton.png" )
        localGroup:insert(titlescreen)
     
titlescreen.x = display.stageWidth / 1.9
titlescreen.y = display.stageHeight / 2.1 
 
 
    local function touched (event)
        if ("ended" == event.phase) then
                director:changeScene( "titlescreen", "fade" )   
        end     
    end
 
     titlescreen:addEventListener ("touch", touched)
 
      -- MUST return a display.newGroup()
      return localGroup
end

I din't understand what you are trying to achieve
if its just showing 2 buttons which takes you to 2 different screens then the below code will do

module(..., package.seeall)
function new()
 
   local localGroup = display.newGroup()
 
 
    local playBTN = display.newImage("Playbutton.png" )
    localGroup:insert(playBTN)
     
    playBTN.x = display.stageWidth / 1.9
    playBTN.y = display.stageHeight / 2.1 
 
  
    local optionsBTN = display.newImage("optionsbutton.png" )
    localGroup:insert(optionsBTN)
     
    optionsBTN.x = display.stageWidth / 1.9
    optionsBTN.y = display.stageHeight / 2.1 
 
 
 
    local function playtouched (event)
        if ("ended" == event.phase) then
                director:changeScene( "titlescreen", "fade" )   
        end     
    end
 
    local function Optionstouched (event)
        if ("ended" == event.phase) then
                director:changeScene( "optionsbutton", "fade" )   
        end     
    end
 
 
     playBTN:addEventListener ("touch", playtouched)
     optionsBTN:addEventListener ("touch", Optionstouched)
 
      -- MUST return a display.newGroup()
      return localGroup
end
