nf function nf(t) t.screen.width = 1280 t.screen.height = 800 end a - love2d works slightly different, expecting users to implement methods that will be called within the game loop - such as love.draw() and love.update() - create a 72 point font using the system default font = (72) - set the font active (font) - set red as the active color (255,0,0,255) - load audio file local song = ( "Ride_of_the_Valkyries.ogg") - we want to loop, we want to loop, we want to loop, we want t^Z song:setLooping( true) - set volume to 50% (0.5) - play song (song) - create a variable for print coordinates to update on touch, default to screen center - LOVE does not have a positionable text object, so we call print each frame local x = ()/2 local y = ()/2 local stringWidth = font:getWidth( "Hello World!") local stringHeight = font:getHeight( "Hello World!") - This function is called once per frame to draw the screen function love.draw() ( "Hello World!",x - stringWidth/2,y-stringHeight/2) end - called on click, move our print x,y to the click location - no touch handler because LOVE is desktop only function love.mousepressed(mouse_x,mouse_y,button) x = mouse_x y = mouse_y end new(font, "Hello World!") - center to screen helloText:setPosition( application:getLogicalWidth()/2 - helloText:getWidth()/2, application:getLogicalHeight()/2 + helloText:getHeight()/2) - set text to red, color is hex encoding helloText:setTextColor(0xff0000) - display text stage:addChild(helloText) - function to handle touch event, move helloText to the touch location function onTouchHandler( event) helloText:setPosition( event.x - helloText:getWidth()/2, event.y + helloText:getHeight()/2) end - register touch function to respond to global touch events stage:addEventListener( Event.TOUCHES_BEGIN,onTouchHandler) - The above doesn 't work in the simulator, so handle mouse too stage:addEventListener( Event.MOUSE_DOWN,onTouchHandler) LÖVE new( "arial.ttf",72, false) - create text to display on screen local helloText = TextField. new( "Ride_of_the_Valkyries.mp3") - play audio file, looping forever local soundChannel = song:play(0,math.huge) - Set song volume to 50%, not set globally soundChannel:setVolume(0.5) - need to load a ttf font, size cannot specify character size in TextField local font = TTFont. a - Helloworld sample - setup our window to our 1280x800 resolution application:setLogicalDimensions(1280,800) application:setOrientation(Application.LANDSCAPE_LEFT) - Load song, cannot use relative path to parent directory since file needs to be added to project local song = Sound. ![]() That is why some versions have two lua files, while others have only one.Ĭa - a application = ) - create text to display on screen in 72point font local helloText = display.newText( "Hello World!",0,0,native.systemFont,72) - center to screen helloText.x = ntentWidth/2 helloText.y = ntentHeight/2 - red helloText:setTextColor(255,0,0) - function to handle touch event, move helloText to the touch location function onTouchHandler( event) helloText.x = event.x helloText.y = event.y end - register touch function to respond to global touch events Runtime:addEventListener( "touch",onTouchHandler) Some files handle window creation in a different file, some handle it in a single file. Then we are going to create a Hello World text/graphic centered to the screen, and position it where ever the user clicks/touches. In this sample we are going to create a window at a resolution of 1280×800, then we are going to start a background song looping ( Richard Wagners – Ride of the Valkyrie taken from here ). If you wish to submit a better rendition, please do so! I do not pretend mastery of any of these suites, or Lua in general, so take the code for what it’s worth. Now we are going to look at a simple Hello World app written with each suite. * Note, I gave iTunes link only, although many of those games are also available on Google Play. Paid cloud computing offering for back-end services ![]() Pro required if income greater than 100K$īuilds occur on Corona Labs servers, internet connection required ![]() Hopefully this will help you decide which engine is right for you.Ĭannot publish to app store with free version Then we will follow up with a simple Hello World example for each, so you can see what the code would look like. ![]() First there will be a matrix of features, to give you an “at a glance” view of what each engine offers. Image.Alright, the title might be a bit over the top… what we are about to do is look at some of the most popular 2D game engines powered by Lua. ImageView image = new ImageView(getContext()) MainActivity- public class MainActivity extends Activity void onCreate(Bundle savedInstanceState) I want to set the height and width based on device size.
