Welcome to the The-Sentinel-VR wiki!
The Sentinel VR is a non profit fan made project which tries to recreate the experience of the classic "The Sentinel" videogame from 1986, using VR technologies. https://en.wikipedia.org/wiki/The_Sentinel_(video_game)
In contrast to other similar projects, The Sentinel VR is aimed to the Android Platform, so this is not requiring expensive glasses to be played. Any cardboard glasses or similar are suitable, and also a USB or bluetooth controler which works as a keyboard to the android devide is needed to control the game keys.
The game has been completely developed in processing for Android: https://android.processing.org/ with no aditional libraries.
During its development I have tried to be as close as posible to the original game, graphicaly and in game mechanics.
Prior to install the game, it is advisable to calibrate the game to your glasses to optimize the stereoscpic experience: https://support.google.com/cardboard/manufacturers/answer/6322155?hl=en
In order to install the game in your Android device you need to download and install the signed apk in the "build" folder of this repository.
Once installed, the menu page will be shown:
The controler or keyboard device must be connected to your Android device.
First, touch on the screen to choose the "SETUP" button. Using your controler or keyboard device, press the keys you want to map to any of the game functions:
Build Block: used to build a block on a tile or on another block Build Robot: used to build a new robot on a tile or on another block Absorb: used to absorb objects: trees, blocks, robots or sentinels. Absorb an object gives you energy to build more objects Transfer: used to move to another robot
After that,a calibration screen apears. Move your Android device to look for a white point. You need to point it until the green point is on the center of the white point:
Then, you are back on the menu page. You can now touch the "PLAY" menu button to start playing.
The game objective is to climbup the landscape util you can absorb "the Sentinel". You can only build on floor tiles: look around and you will see that the tile you are looking at will tint green. By pressing the adecuate button on the controler, you will build a block or a robot. Building a block cost 2 energy units, building a robot cost 3 energy units. Your energy is shown at the top of the screen. Once a new robot has been built, you are able to "transfer" to it, using the transfer key. You need to look to the new robot (the robot will tint green), and press the transfer button on the controler device. Your conciuos will travel to the new robot. The old one is left behind, so I advice you to turn around and reabsorb it to recover its energy. That way you will climb up in the landscape until you are high enough to absorb the sentinel. During the way you can absorb trees to get more energy. Trees are absorbed by pointing at their tiles. Each absorbed tree gives you one energy unit. The sentinel is in the highest place of the landscape. It slowly turns on its tile, scanning the landscape. If it is able to see you, a warning sound advices you and a red point appears on top of the screen. In that moment, you are in danger, cause the Sentinel will slowly drain your energy. Thus, you better transfer to another robot. If your energy reach 0, you are dead. It is a good strategy to move to tiles which are behind slopes, so you can hide from the Sentinel look. If the sentinel is not able to see the tile you are placed on, then it is no able to absorb your energy. You will hear a diferent warning sound, and a green dot on top on the screen, meaning that the Sentinel is looking at you, but it is not able to see your tile, so you are safe! Once you are high enough to see "The Sentinel" tile, you can absorb it. Then, you can build a robot on its tile, a transfer to it. Doing that, you have beat this level, and will move to the next world. Each new level has increased dificulty. New small "sentinels" will aprear, increasing the chance you may bee seen by a Sentinel!
