    Flash Game Engine Programmer (AS3)

    United States - Last active: 18 hours ago - Tests: 4 - Portfolio: 51

    As a Flash game engine programmer, I am adept with the low-level engines for browser-based, 2D, single-player Flash games writing ActionScript 3. My own Flash games have also been sponsored, and I have coded over 50 Flash game engines for clients. Services and terms: 1). Programming and development of the game engine for single-player, 2D, browser-based Flash, non-ad game(s). This is game engine programming exclusively, and does not include designing the game(s), content management, building the web page(s) on which the game(s) might be hosted, or implementing or configuring other server-side resources (high-scoring, login system, user accounts, web scripting, databases, etc.) 2). An ideal minimum duration for the project should be at least 3 months. The project must be for the development of a new game engine, thus, not modifying an existing one, unless I was the previous, sole developer of that engine, and the engine has not been modified by someone else after I have worked on it. Furthermore, the project must not include integration onto third party social sites, such as Facebook, nor must the target platform designate mobile devices. An exception here is if I produce a Flash SWF, then send it to you (as the engine would be complete at this point), then on your end, you convert/port it to your desired platform. 3). Game design details, gameplay mechanics, media (graphics and audio) must already be provided. This includes, but not limited to concepts, gameplay rules, scoring systems, and user interface layouts/functionality. Please contact me if you have any questions.
