Tron

Objectives

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

Getting started

You will need to create a public repository with the name tron. Next you need to create a file named ai.js. It must respect the instructions given

Controls

• arrows or scroll to move step by step
• shift will make it fast
• you can click anywhere on the progress bar to seek into the history

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 biggest score wins

How to write your AI

• Copy the code on the file random.js to your file, ai.js
• You may now edit the update function which is called each turn

⚠️ Do not rename the update function ⚠️
as it's the function that the worker will try to run to test your AI.

How to test your AI

• You may use this link tron, to test your AI
• You need to add your AI as a user in that link

  Example:

  • if your git login is Frenchris and you want to test against LEEDASILVA the link becomes: /public/subjects/tron/?ai=Frenchris@master+LEEDASILVA@master
  • if you want to test against the default /random.js AI the link becomes: /public/subjects/tron/?ai=Frenchris@master+/random.js
• 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)

// And I return a random available coord
return pickRandom(available)

...with this line:

// always return the first free coordinates
return coordsInBound.filter(isFree)[0]

• save the file, push the changes and re-run 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 controlling 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.
