Setting Up a Game

gogizgaz

Hello!

I have been using codea for a while now and have produced a few small projects. But I want to embark on making a full fledged game, with a homescreen and levels etc etc. I am not sure how to go about this, for example in xCode I can switch between different viewControllers which make it clear what gameState is running.

Is the best way to do this in Codea, is to add a bunch of if statements inside draw() and let them activate depending on which gameState I am currently in?

Thank you

@gogizgaz This isn’t a game, but the idea might be something like what you’re after. I move around to different screens that do different things with just 2 statements in draw. When you go into a web site, tap Done in the upper left of the screen to return back to the program.

displayMode(FULLSCREEN)

function setup() 
    func=menu    -- start screen

    buttonTab={}    -- buttons table

    -- buttons that show on the menu screen
    table.insert(buttonTab,button(350,600,100,50,"Screen 1",menu,screen1))
    table.insert(buttonTab,button(350,500,100,50,"Screen 2",menu,screen2))
    table.insert(buttonTab,button(350,400,100,50,"Screen 3",menu,screen3))
    table.insert(buttonTab,button(700,50,100,50,"EXIT",menu,close))

    -- buttons that show on screen1
    table.insert(buttonTab,button(350,600,150,50,"Google",screen1,url1))
    table.insert(buttonTab,button(350,500,150,50,"twolivesleft",screen1,url2))
    table.insert(buttonTab,button(350,100,150,50,"Menu",screen1,menu))

    -- buttons that show on screen2
    table.insert(buttonTab,button(350,600,150,50,"map quest",screen2,url3))
    table.insert(buttonTab,button(350,100,150,50,"Menu",screen2,menu))

    -- buttons that show on screen3
    table.insert(buttonTab,button(350,600,150,50,"amazon",screen3,url4))    
    table.insert(buttonTab,button(350,100,150,50,"Menu",screen3,menu))
end

    background(40, 40, 50)
