RTG - The Ray-Traced Game : The first DevLog on GameJolt


Hello,

I would like to introduce you new game which is in development now for few months. Game's highlight is the use of ray-tracing engine to display game's world. Apart of it, game will be played like classic 2D puzzle / platformer (although, the world will be full 3D with camera looking from side, so gameplay itself can be in 2 dimensions).

For first devlog, I would like to catch up with current progress:

  • took my ray-tracing algorithm from my bachelor's work which I made when I was on university. Refactored it completely to my today's coding standards. Compiled it and ran it after 17 years. Yess!

  • wrote C# wrapper around ray-traced scene, objects and lights (RT algorithm is C++ thing) and integrated it into my engine and editor in which I made my previous game Universe Quiz (available on Steam). In C# I have already coded much better objects management, serialization, scripting, editing, etc.., things which are more awkward to implement in C++.

  • started implementing RTG / platformer specific code above my engine. It means, camera looking to scene from side, actor with 2D collisions, terminals which you can access in game to read hints or story, end level portal, switch to open doors, etc.

  • made few test levels to test basic mechanics and algorithm output

Attaching few animations from test levels which will say more about current state of progress. Short resume of animations:

1. Chessboard animation: my original demo from university

2. Very first three simple tutorial levels

3. Carriable light tutorial level

4. Algorithm features showcase level (shading model, specular reflections, mirrors, color mixing, etc..)

RTG Flashback - Luces Mortales #2 Un ejemplo donde "luces mortales cargadas" son usadas no sólo como elementos de acción, sino también como elementos puzzle. Hay que buscar solución como bloquearlas para vencer un nivel. https://store.steampowered.com/app/4032050/RTG

RTG Dev Flashback - Deadly bouncing lights Example how those deadly lights are used not just for action but also for new puzzle types. You have to block them in favorable way in order to advance further. Wishlist RTG on Steam: https://store.steampowered.com/app/4032050/RTG

RTG Flashback - April 2021 #2 Level from my sci-fi puzzle/platformer, involving use of "carriable boxes", a puzzle mechanics which is used extensively in the game, along with more game mechanics which will be presented later. https://store.steampowered.com/app/4032050/RTG

Dev Flashback - Nov '21 #3 End of 2021 was very productive in RTG development. After "charged light shooters", I implemented "gravity inverters", great mechanics with lot of potential for new puzzles. Here's small showcase. https://store.steampowered.com/app/4032050/RTG

RTG Dev Flashback - July 2022 "Deadly bouncing lights" was the last gameplay mechanics I added to the game. They opened possibilities of more action levels although I invented many interesting puzzles involving them as well. https://store.steampowered.com/app/4032050/RTG

Dev Flashback - Jan '22 Another flashback! In January 2022, I had majority of puzzles already done. Despite that, big amount of work was still before me (80/20 rule). In animation you can see one of later levels in the game. https://store.steampowered.com/app/4032050/RTG

RTG Flashback - Enero 2022 Hola! Otro flashback de desarrollo de RTG. En enero de 2022, ya tenía mayoría de niveles hechos. A pesar de eso, todavía tenía montón de trabajo adelante (la regla 80/20). https://store.steampowered.com/app/4032050/RTG

RTG Dev Flashback - Nov '21 #2 Another level with "charged light shooters". I can say, that's around this level when game's difficulty spikes up. After 20-30 levels of quite light puzzles, the game will start challenging even skilled puzzle players.

RTG Dev Flashback - Nov '21 Charged light shooters! Mechanics, which added "pool" or "billiards" gameplay. Lot of fun with that. Moreover, this effect of environment illumination is for free thanks to game's engine, so why not use it?

RTG Flashback - Nov 2021 #3 Fin de 2021 fue muy productivo en desarrollo de RTG. Después de "tiradores de luces", implementé tb "inversores de gravedad". Aquí está una animación de esa funcionalidad. Este es sólo nivel de prueba. https://store.steampowered.com/app/4032050/RTG
