TheSentinel-2nd-Look (W.I.P.)
A fully path traced remake of Geoff Crammond's iconic 1986 game, The Sentinel - runs in your Desktop/Mobile browser! <br>

<br>
<h4>Desktop Controls (update 7/30/22: Mobile GUI/Controls coming soon, now that Mobile rendering is working!)</h4>
- Click anywhere to capture mouse
- move Mouse to free-look
- Right/Left Arrows to open/close camera aperture (depth of field effect)
- WASD,QZ to fly camera in Landscape selection mode (disabled when entering your Robot in game mode)
- Press SPACEBAR to generate a new random landscape (cycles through 4 color themes)
- Press ENTER to enter the player's starting Robot (this is where you start each game level)
- With a checkerboard tile (or boulder) selected, Press R to create another Robot
- With that new robot selected (or its checkerboard tile selected), Press E to Enter that other robot
- With a checkerboard tile (or another boulder) selected, Press B to create a Boulder (a base on which more Boulders or another Robot can be stacked)
- With a checkerboard tile (or boulder) selected, Press T to create a Tree (a technique to partially hide your player Robot from the Sentinel's gaze!)
- MouseClick to absorb an item. Note: game rules state that you must be able to see the checkerboard tile on which the item sits (will not work if the item is too high). Does not apply to Boulder bases or player Robots - they can be clicked/absorbed from anywhere on the level.
- Press H to Hyperspace to a new random tile location, at or below current player height - Warning: Hyperspacing costs 3 energy units!
- If player energy drops below 0, the level is lost and the player restarts the same type of level
- To Win a level, Press H to Hyperspace while standing on top of the Sentinel's pedestal (after you absorb her and place your robot where she was!)

<h2>TODO</h2>
- Make the Sentinel Game! lol - now that the rendering is mostly worked out, add the actual gameplay and game logic.
- Upon seeing an object with more energy than a natural tree, make Head Sentinel and her lower Sentries dissolve and break down the object.
- Add simple GUI showing player assets as well as player visibility to The Sentinel and lower Sentries.
- Add the classic original sound effects and short recurring melodic theme.
- Now that Mobile rendering is working, add mobile GUI/buttons and increase mobile performance (framerate)
<h2>ABOUT</h2>
- Following my Path Traced Pong game, this is the third in a series of real-time fully path traced games for all devices with a browser. The technology behind this game is a combination of my three.js path tracing project and the WebAudio API for sound effects. The goal of this game project and others like it is to enable path traced real-time games in the browser for all players, regardless of their system specs or GPU power. <br>

This is a remake of the iconic classic 1986 game, The Sentinel https://en.wikipedia.org/wiki/The_Sentinel_(video_game) by Geoff Crammond (Amiga screenshots) http://www.grospixels.com/site/sentinel.php . Originally for the BBC Micro, it was soon ported to different systems of the day, including the Commodore 64, which I owned. I'll always remember - I was 13 years old, strolling through the mall with my parents (yeah I wasn't so cool), when I saw The Sentinel game for the first time - a demo running on a Commodore 64 monitor in Babbage's (an old computer software retailer) store front display to all mall pedestrians. I stopped in my tracks. This was the first true 3D filled polygon game running on the Commodore 64! (albeit with a really low framerate, understandably!). I immediately walked in the software store and bought it that day - I still remember how the big black Sentinel game box looked and felt. <br>
<br>
Later when I got home and for many months afterward, I not only enjoyed endless hours playing it, but it actually had an effect on me that no other game has since. It showed me what a computer game is capable of: not just a toy to dump quarters into at the mall arcade, but an entire world (well, landscape) that pulls you in, surrounds you completely, and makes you feel that you are really there. I don't know how the creator/programmer, Geoff Crammond, came up with this amazing idea, nor do I even know how he got 3D filled polygon graphics to run at all on such underpowered systems, but what I do know is that this game and its gameplay is like no other. Its sterile, haunting atmosphere sticks with you (or at least it did back when I was a teen). It rises above how society regarded computer games to the level of true art. Geoff Crammond was able not only to convey his other-worldy vision on 1986 hardware, but in my humble opinion he created a truly unique real-time masterpiece that needs to be documented and cherished. <br>

My remake of the game, which I call The Sentinel: 2nd Look, hopefully brings the classic into modern times so that a wider audience can enjoy it at 30-60fps on any desktop/laptop with a browser. What better way to bring together my favorite game of all time and my favorite graphic technique (path tracing!) into one project! Now I know that there are a few modern fan remakes out there already, but I wanted to do something slightly different with my version and add my path tracing touch to it. Since I can't wade through Geoff Crammond's original assembly source code, I had to reverse-engineer the game's landscape generation process. This alone took months because it's not too obvious how he coded it and I went down a couple of wrong/dead-end paths on my journey to faithfully recreate the look and feel of his cool landscapes. Graphics-wise, I added a day cycle/sun light source to the environment, added full path tracing to cast pixel-perfect shadows on the terrain, self-shadowing of game objects, and providing true ray-traced reflections in the white/black connector panels of the landscape. It's really rewarding to fly high and low and explore the environment, watching the setting sun cast eerie shadows on the landscape and game objects. I hope you enjoy my homage to this iconic game, and I hope it gives you that magical sense of immersion like I had when I was 13 at my Commodore 64! :)
