In this project you will have to create your own Tron Ai snake

Getting started

First, clone this repo : https://github.com/01-edu/tronBlank

then execute the command below.

http-server tronBlank/

if http-server is not installed do this command:

npm install -g http-server

Controls

• space toogles autoplay
• right arrow plays one move
• up arrow increases the autoplay speed
• down arrow lowers the autoplay speed
• R reloads the same play
• S loads a new play (new seed)

Rules

• Your Ai has to move every turn (it can not stay still)
• Every time the Ai moves somewhere the Ai leaves a color trail.
• the Ai can only move to a blank tile.
• the Ai can not move out of the map (100 x 100)
• the Ai can only move to its left, forward or its right. (Moving backward is suicide as it would hit its own trail !)
• If too much CPU power is required to decide where to go, the Ai dies.
• If two Ais moved to the same spot, both of them die.
• The Ai has to survive as long as it can.

The game ends

• Once no players can make a move
• The player with the longest trail wins

How to write your AI

• Copy the file /ai/random.js to /ai/GITHUB_LOGIN.js
• You may now edit the update function which is called each turn

How to test your AI

• Suppose the link provided by http-server is : http://127.0.0.1:8080/?seed=somevalue&users=random

• You need to add your ai as a user in that link,

• Example: if your ai file's name is /ai/Frenchris.js the link becomes: http://127.0.0.1:8080/?seed=somevalue&users=Frenchris,random

• Open the inspector of the browser used and disable the cache

• let's change the update function so that your ai only goes forward.

replace this line just before the return of the update function

 const available = coordsInBound.filter(isFree)

with this line

const available = coordsInBound.filter(isFree).filter(el => el.direction === 0)

• save the file and rerun the game in the browser. If the cache was correctly disabled, you have changed your ai behaviour from a random pick of available moves to only going forward.

• To understand better the way of controling your AI, read the comments inside the Ai file and do a lot of testing.

• When peer-corrected, you Ai will be competing against other Ais. Be aware that there will be the possibility for the peer-correcter to use his or her own Ai.

May the best tron win :)

Have fun and good luck.
