Description

My first professional game developed in a game studio. A 2D Puzzle-Platformer Adventure, based on White & World, a Game Jam project in which some members of the team worked, and that you can found in this portfolio.

The game mechanic basically is destroy the enemies, in the correct order, to create or destroy parts of the level, to reach the exit point. The exit point can only be enable when the all enemies are eliminated.

The game was developed using an own XNA based game engine, TLSA.Engine, a newer version of my old game engine TLSA Engine (based on Visual Basic 6.0 and dx_lib32, an own game framework).

Description

A project for the Game Jam in GameDev area of Campus Party España 2011. A game inspired in the classic Lemming. The game was programmed with TLSA.Engine, a new version of my old game engine in Visual Basic 6.0 and dx_lib32 (an own game framework). This version is based in .NET, C# and XNA.

The restrictions of the Game Jam were: octopus, teleports and randomness.

Languages supported: Visual Basic 6.0

Description

A 2D Game Engine based on dx_lib32 Project, with the purpose of develop a 2D platform game like Flashback or Another World.

  • Entity object oriented engine, trying to simulate the XNA architecture.
  • 2D graphic engine multilayer sprite based, implement a control point map to manage easily multiple textures and transformations in a group object (to create complex animations, based in multiple pieces, with independent sprite animations), simple camera (with support to define multiple scene cameras, to switch between them easily).
  • 2D audio engine, with support for basic effects and spatial system to simulate distances and position listenings.
  • Simple game input engine, bases on actions, which can define multiple input (keyboard, mouse and joysticks or gamepads), with Force Feedback support and XInput support for XBox 360 Gamepad.
  • Basic collision engine, with multiple layer collision, spacial partition, raytracer and force emitters (to simulate explosions or black holes).
  • WYSIWYG level editor with flow controls (play, pause and restart scene during the debug), scene physics designer, an audio areas designer (for applying effects and emitters) that uses the physics defined in the scene, and visual debugger.
  • Input editor to create profiles input files, with define actions and her input controls, to import in the game engine easily.

The first versions of the engine development are from 2005 and 2006. The last version, reprogrammed from zero, started development during the summer of 2009, and during until the last built, in summer of 2010.

This game engine is not finished, because the complexity to develop a project as this in Visual Basic 6.0. The game engine was used in few projects, mostly a prototypes.

Description

Game framework or API (or also wrapper) that enable to access the power of DirectX APIs to Visual Basic 6.0 developers. A simple framework composed of 5 specialised classes: a graphics class, an audio playback class, a game input device manager class, a video playback class and a helper class with a set of functions to cover multiple needs.

It's compiled as an ActiveX DLL, with a minimum dependency libraries (the Visual  Basic 6.0 runtime, the ActiveX library to connect with the DirectX 8.1 API, and the OGG Vorbis libraries), included in the setup, and it's compatible with any version of Windows, from Windows 98 to the current Windows 10 (desktop version only) and future Windows with Win32 and DirectX 8.1 support (today, it's working properly on Windows 10).

The project started development in early 2001, under DirectX 7 API (changed to DirectX 8.1 in 2002). The first functional version was released in 2004, with only a set of program samples as documentation reference and a forum to consult doubts. The second version was released in early 2006, with a full set of program samples, in Visual Basic 6.0 and .NET formats, and with a full API reference documentation in Windows Helper format. The final version, after several bugs fixed and new functionalities, was released as open source project in GitHub in middle of 2012.
