The latest additions of sample code and code libraries shared by developers for Corona SDK.
This code allows you to move your player by touching the screen. The grid will then manipulate according to the players position. You can change the radius of the manipulated area, and change the line width. We are having problems with lag if there are multiply objects on the grid. If anyone can help solve the issue, we will update our code accordingly. Hope this helps! More...

This code creates an app with a single, full screen native web overlay control. The main.html is loaded into it and JQuery is then used to repeatedly load a file indicating the device orientation. The orientation is detected within Corona and written to another HTML file. CSS is used to re-orient the web page within the web overlay control. Known issues: Demo does not adjust widths of HTML elements yet Demo does not... More...

You can change the bUseListener value in cSceneLoad.lua to specify if you want the bar updated every frame, or just when each data chunk has been loaded (preferred method).

It isn't a major thing, but I find it can be useful. I have not yet thought of a way to do it without physics. How I do it: The code will make an object called "arr" (I don't know why I called it that) which is attached to the player. The players rotation is found by finding the angle between the player and the arr object. This will run on its own: 1 2 3 4 5 6 7 8 9 10 11 physics = require( "physics... More...
