Description

The ultimate couch fragger gibfest! Armed with a powerful boomstick and bullet deflecting shield, up to four players wage unholy war against each other as they compete for souls in nine different local multiplayer game modes (wave mode for 1-2 players also included) across four realms and 40 arenas. This is demonic local multiplayer action at its bloodiest!

A really fun game for play with one or three friends in local!

Gameplay programmer for the porting to Xbox One and PS4 during  mi period in Stage Clear Studios on 2018. Working to improve the performance and stability on console of this game, performance in code and in draw calls, and to finish the console services integration in code, also solving critical problems with the multiplayer, UI and input implementation, and bad using of plugins and frameworks.

Dependency Injection and the InControl plugin: the downway to the hell in Unity

One of the critical issues in this project was the over engineering applied by the original developers when using a bad implementation of Dependency Injection (or Inversion of Control) architecture in Unity using a third-party framework. This issue results in a very complicated code to debug using the Unity and Visual Studio debuggers because the code makes random and unexpected traces in execution, and this results in more time to port the game to XBox One and PS4 consoles (this project took more of a year to was completed the port to both platforms and pass the TRCs to be published).

Other problem to solve in this port was the bad use of InControl plugin, a popular multiplatform input manager for Unity (and the source of most of the bugs to fix in the most of projects that I worked during a year in Stage Clear Studios). Most of the problems to fix was the InControl implementation with the multiplayer logic and the user session pairing. In PS4 adding a critical bug when the console return from the suspension mode (turn off the console when the game is running and turn on to return the previous session). In PS4 (almost in this project), InControl stop to working after the console return from the suspension mode. This result in fail the TRC process when try to publish a game to Sony.

Because the InControl source code is a mess to apply custom fixes, my solution was the implementation of an own lightweight input system using the built-in Unity input system (based on the input system implemented in my master degree final project, Argos: CICE MPV Project) and the needed calls to PS4 DualShock functions (mostly for vibration). Basically, my system was a wrapper that catch any InControl call, and remaped to Unity built-in input system, recreating all needed classes and structures from InControl API to ease bypass the plugin without rewrite any line of code of the game.

Description

Lead Programmer and Tool Programmer for the development of MEGA Sport Training, an interactive experience for MEGA: Mundo Estrella Galicia museum, in A Coruña, Galicia, Spain.

My main task in this project was develop the entire game architecture, focused on modularize all critical parts of the project for ease maintenance, upgrade or deep-changes quickly, the creation of requested tools during the development, and supervising the work of a junior programmer, the person that was develop the 4 mini-games that compose the game (basket, football, hockey and rugby) and help me to integrate the Kinect v2 SDK in Unity and study how implement features like the advanced gesture recognition.

Other tasks that I colaborate was supporting the 2D and 3D artists as Technical Artist, optimizing all 3D assets and materials in-game (combining meshes, fixing materials setup in Unity, and advise the 3D artist, a junior profile, in some tasks involved with optimizing modeling and asset exporting), setup the lighting in all scenes and setup all post-processing effects to fit the limited requeriments of the target machine (an Intel NUC without dedicated graphics card) to achieve a good performance without lost quality visual look & feel.

3D Wire 2019

This same year, we make a variation for the 3DWire (https://3dwire.es/), an important spanish annual event of animation, games and new media that is celebrating in Segovia. Weird Games: Food Training is the new name of the game and have a little visual changes as replacing all sport things like the basket ball by a toaster or the hockey disks by spanish omelets, most of the work as rebranding and applied some gamification rewards for the event games.

The true challenge: Kinect 2.0, Windows 10 and beyond

Also of the difficulties recording custom gestures using the official Kinect SDK tools, implmenting a custom gesture system to avoid some issues with some gesture recognitions, and the many other related and technical issues, the true challenge to develop and maintain this project are the Kinect 2.0 + Windows 10 combo:

  • Kinect 2.0 has been discontinued by Microsoft in fall 2017 and removed support on Windows (drivers, tools, etc...) a few months after publising the tools for Kinect 2 for Windows (supported Windows 8.1 as last official version).
  • Never existed an official SDK for Unity, only a few outdated particular user implementations on the web for Unity 5.6 (we developed the game with Unity 2018.3.5). We using the only full implementation solution available and well documented by examples, that can be found in the Asset Store.
  • No all PC configurations supports Kinect 2 hardware. During the pre-production, we found that only 2 PCs in our studio are capable to run Kinect 2 without problems. Other PCs directly can't work, can't recognized the Kinect hardware. Seems the USB 3.0 in most of them has issues related with power supply or the drivers (in some cases, Kinect burned the AC Power unit on a couple of our PCs).
  • Kinect 2 hardware can't works on current versions of Windows 10. The last supported version is the build 1803 (April 2018 Update). The USB 3.0 drivers has many known issues and one of them affect to Kinect 2 USB connector. The solution initially seems very simple: using the build 1803, but...
  • In Windows 10 you can't full disable Windows Update services. And, later or soon, your Windows 10 will be forced to upgrade to latest version. In our case, disconnect the PC from the net is not a solution. The PC can not we unpluged from the net because need access to internet to send mails and send and read signals from an UDP server. Basically, the solution passed to reroute the all Windows Update known server address to localhost in the Windows hosts file, setup all Windows Update related services to manual and disabled it, and blocking the internal Windows folders related with Windows Update downloads and deployments.
  • The official Kinect 2 AC Power Unit not works on current PC configurations. One of the Kinects, supplied by the museum worked with the Surface 3 AC Power Unit instead of the Kinect official unit. For any reason the Kinect 2 official AC Power Unit not works properly on current PCs.

And the final boss...

But the true challenge was the final issue of the Kinect 2 + Windows 10 combo. At the final stages of the development and testing, we found the game sometimes was freeze without any reason! (very inappropiate for a museum experience).

After 2 weeks of deep debugging and testings in the source code of the Unity implementation of the Kinect SDK, I found that the reason of the game was freezing was the avatar recognition event in a driver level. It's seems that the outdated driver in Windows 10 has any internal memory leak or something related bug.

Because I'm not was capable to fix this, because is an internal driver bug and not a source code issue, I designed a little "trick" to able the game to catch the freeze state and reset himself. I developed a little program that works as a monitor instance of the game. A simple terminal program that run in fist place and launch a new instance of the game as child process. Basically the game instances comunicate with the monitor to tell that it's alive. When the game stop to send signals to the monitor, the monitor understand that the game is freezed, kill the freezed process and launch a new one.

For prevent the user noticed the game reseting process, as idea of Carlos L. Hernando, we empty the entire Windows desktop of icons and hide the task bar, and using the same game splash screen background as desktop background. With this, the user not see any stranger thing except that the game has return to the main menu screen.

P.D.: In a way to avoid several freezes and their resepective resets, I needed to reimplemented all avatar recognition logic system in the game to avoid conitnuous calls to native Kinect avatar recognition functions.

Description

Gameplay programmer for the porting to Xbox One, PS4 and Nintendo Switch.

I worked on optimization tasks on code and graphics assets in scenes, mainly reducing polygons in major objects in scene, like the pipes, implementing a system to switch original pipe models for a low-poly version when the puzzles are solved (the original pipes, that the player see when play a puzzle, are a compound of several high-detailed meshes with detailed interiors, very unoptimal for realtime videogame rendering), and removing several duplicated/overlaped sprites on decorations (and improved the sprite materials with help of our in-house technical artist, Sergio Bernardo) to reduced the several overdraw and draw-calls when the game shows the entire island or large areas with solved puzzles.

Other task consisted in adapted the user session for working with the console systems, and save game implementation and other related game state code to avoid continuously read/write operations on disk (or the NAND memory in Switch) major bugfixes related with the original Steam version and last-hour game workflow changes requested by the game developer.

P.D.: Before the last Nintendo Switch SDK version on november, Unity games on Nintendo Switch they couldn't reach the full potential on the GPU. Because this, initialy, in an effort to reach almost 30 fps, we created an alternate version of the island scene for the Nintendo Switch version and applied several cuts on effects and decorators, like the water waves effects and some sprite layers in most of the wall decorators like the hedges.

Description

A killer puzzle game where you control Skullface, a psychotic slasher bent on slaughtering camp counselors at the title campground. Slide this adorable voxel murderer around hundreds of isometric puzzle levels to squash, flay, and decapitate the hapless victims in this darkly comic homage to 80s trash horror.

Gameplay Programmer for the porting to Nintendo Switch and PSVita console versions. I worked on optimization tasks on code and graphics assets in scenes. Other task consisted in adapted and improved some UI elements to use in touch screen and major bugfixes on this platforms.

PSVita version was required most of the enfort, was the most difficult platform to port. Mainly I needed to reimplemented most of the original game core to ensured to fit in the low hardware requeriments, I implemented new resource management systems to cached reusable assets (sounds, textures, etc...) and background load processes (this is the only version that requires of loading screens between scenes and other game states). Also I applied extreme optimization in all graphics assets to avoid continous VRAM overflows adjusting size and compresion parameters in a right way to preserved the original visual feel in the PSVita screen resolution.
