Scaling on galaxy tab

Games
#1

Hi,

I am trying out my game with a different setting now as i have seen some sample projects using 320 * 480 and providing @2x graphics and some using 1024*768

Here is the config.lua settings for my game which is about catching objects falling form the sky in a basket below :slight_smile:

width = 768,
height = 1024,
fps=30,
scale = “letterbox”,

All the graphics by default are drawn for 1024*768 resolution.

works consistently on iphone, iphone4 and ipad on the simulator, but the moment i take it on the galaxy tab the background does not draw properly leaving black bands on both sides in portrait mode.

When i set to zoomEven, the background draws properly, but some activity happens outside of the screen even though i initiate objects from the sky using x as a random integer between 0 and display.viewableContentWidth.

I have not created any @2x graphics?

I have also seen games literally hard coding positional values for objects , assuming corona will provide the translation between various screens in terms of positioning.

any sample game which uses 1024*768 and appears correctly on galaxy tab?

thanks

The resolution you define in your config file is what Corona uses for how your app is displayed (as well as how physics calculations are determined). The iPads 1024 x 768 resolution is a full screen aspect ratio which is 4:3 so it looks almost square. The Galaxy Tab has a widescreen aspect ratio which is 16:9 and is much more rectangular. What Corona is doing when you choose scale = “letterbox”, is displaying the content in it’s original aspect ratio so it won’t fill up the whole 16:9 screen (which is why there are black bars). A great article with a section on how to set up your app to display properly on just about any device can be found here:
