horse-simulator's Introduction

Horse simulator

Implement a horse racing simulator with PHP and a relational database

  • Each horse has 3 stats: speed, strength, endurance
  • Each stat ranges from 0.0 to 10.0
  • A horse's speed is their base speed (5 m/s) + their speed stat (in m/s)
  • Endurance represents how many hundreds of meters they can run at their best speed, before the weight of the jockey slows them down
  • A jockey slows the horse down by 5 m/s, but this effect is reduced by the horse's strength * 8 as a percentage
  • Each race is run by 8 randomly generated horses, over 1500m
  • Up to 3 races are allowed at the same time

The webpage should include

  • A "create race" button which generates a new race of 8 random horses
  • A button "progress" which advances all races by 10 "seconds" until all horses in the race have completed 1500m
  • Any currently running races, showing distance covered, horse position, current time
  • The last 5 race results (top 3 positions and times to complete 1500m)
  • The best ever time, and the stats of the horse that generated it

Result

Requirements

  • php-cli
  • make
  • composer
  • additional requirements in composer.json and dependencies

Start project

make

Open URL showed in console (default is http://127.0.0.1:8000)

Run tests

make tests

Things to improve

  • write tests (code rely on phpstan and type-safety for now)
  • fix flashbag configuration (errors, ok messages not showed)
  • fix bug that fetched horses not hydrated properly from "left join"
