HOCKEY2DA C++ Videogame Using the SDL 2.0 Library

By PaintedLady

What is the SDL Library?

• Commonly used to write high-performance video games and other multimedia

• Offers a wrapper around the OS-specific functions the game engine needs to access

• Allows us to focus on the game, not the integration

What is Hockey2D?

It’s a competitive 1 v 1 sports video game on Windows

A Hockey Game:- Players skate on the ice (ice physics)- Players try to score goals, and prevent the opponent from scoring- Players control one skater each.

A Platformer:- Platforms add & balance gameplay- Simple movements- Easily picked up by new players

Quick Prototype Demo

Iterative Development

Keep playing & readjusting existing build to:

- tweak & perfect existing gameplay elements- iteratively add new features & assets (such as nets, scoreboard, etc)- ensure gameplay feels smooth and natural

- Make game fun

Elements of the game we can tweak through iterative development:

- Physics elements (how the puck feels, player acceleration)- Player actions (shooting, body-checking…)- Speed of moving nets…
