Get the source code of Slingy, a Flash game I would like to see on mobile devices

Read all posts about "" game

More than three years ago I released Slingy game, sponsored by Hairy Games.

The game did not have the success I expected, but today I played it again and I thought it would be nice to have a similar game on a mobile device.

So I am giving you the source code of the game, with a lot of outdated libraries like Mochi Media and Playtomic APIs, but you will find the game engine, powered by Box2D, quite interesting, have a look at the main class:

package triqui{
	import flash.display.Sprite;
	import flash.events.MouseEvent;
	import flash.events.Event;
	import flash.events.KeyboardEvent;
	import Box2D.Dynamics.*;
	import Box2D.Collision.*;
	import Box2D.Collision.Shapes.*;
	import Box2D.Dynamics.Contacts.*;
	import Box2D.Common.Math.*;

Moreover, I will make a Box2D Phaser prototype soon, to see if it can be nicely played on mobile like I think.
