Battleship! is my term project for 15-112 in summer school. It is a modified version of the original board game Battleship. The game is implemented in Python 2.7 with Pygame.

Unlike traditional Battleship, this WILD version allows players to move the ships and scan a small area to reveal the enemy. Players win by either destroying all enemy ships or moving any ship to the enemy’s back line.

Online Ranking System for Hearthstone Competition

The Online Ranking system for SCIE eSports Club finally came online! Now this system will be used to facilitate the HearthStone Ranking Competition.

Contestants can login using their personal account, see their current score and rank, start new challenges and view challenge history. Meanwhile staff can manage the system through the admin view, which allows them to manage contestant’s info and set competition results.

The system is based on DJango, which is, in my opinion, one of best web frameworks. I self-learnt DJango from its online tutorial and found that it’s extremelly powerful, manageable, and has lots of conveinent features which save me hours of work.

Since this is my first try writing a web application and it’s still in development, please DON’T TRY TO EXPLOIT/HACK the system! If you find any bugs or have any comments, please tell me and we can fix it together.

How to Access

The system can be accessed directly at http://hs.esportssz.com/hs/

Also, during the competition season, you can access it using the menu of the Official Wechat account (scieesports).
