My Corona SDK Quick Reference Items

This is just a quick list of reminders and tips that I look at when working on a project...I have these printed out, scribbled and post-it noted all over my desk so i figured I would make this post and clean up my workspace along the way.  You might find them useful...or not. :)

Common Screen Resolutions (Portrait)
iPod Touch - 320x480
iPhone 3G - 320x480
iPhone 4G - 640x960
iPad - 768x1024
Droid Incredible - 480x800
Droid X - 480x854
Evo - 480x800
XOOM - 800x1280

Gestures to account for, or not:  Tap, Drag, Flick, Swipe, Double Tap, Pinch Open, Pinch Close, Touch and Hold, Shake

Apple recommended minimum tappable size of a UI item:  44x44 points

Icons needed to support an Apple and Android deployment - (Start at a 512x512 image size, because you are going to need this for app submission, make all these smaller ones from that so you don't end up with a blurry/stretched 512x512 when you are all done - or used SVG or vector of course)

• Icon@2x.png (114x114)
• Icon-72.png (72x72)
• Icon-hdpi.png (72x72)
• Icon.png (57x57)
• Icon-mdpi.png (48x48)
• Icon.ldpi.png (36x36)

Base config.lua file:  (This is my basis for supporting Dynamic Image Resolution )

application = 

{

content = 

{ 

width = 320,

height = 480, 

scale = "zoomStretch",

fps=60,

imageSuffix =

{

   ["@1x"] = 1.5,

["@2x"] = 2,

["@3x"] = 2.4,

}

}

}

Base build.settings file:

settings = 

{

    android =

    {

      versionCode = "1"

    },

        

orientation = 

{

default = "portrait",

supported = 

{

"portrait",

},

},

        iphone =

        {

                plist =

                {

                        UIPrerenderedIcon = true,

                        UIApplicationExitsOnSuspend = true,

                        CFBundleIconFile = "Icon.png",

CFBundleIconFiles = {

  "Icon.png", 

  "Icon@2x.png", 

  "Icon-72.png", 

},

                },

        }

}

Some optimization tips:

1. Get Rid of Blurry Text For Good!
2. Definitely evaluate Director 1.3 and see if it fits your needs! If it does throw Ricardo a few bucks, this is a great jump start to a project!
3. More tips from base2solutions
4. Check your FPS
