Using Box2D


As previously said, Box2D is a physics engine. It has a lot of features, but the most important for the project are the following (taken from the Box2D documentation):

  • Collision: This functionality is very interesting as it allows our tetrimino to interact with each other

    • Continuous collision detection

    • Rigid bodies (convex polygons and circles)

    • Multiple shapes per body

  • Physics: This functionality will allow a piece to fall down and more

    • Continuous physics with the time of impact solver

    • Joint limits, motors, and friction

    • Fairly accurate reaction forces/impulses

As you can see, Box2D provides all that we need in order to build our game. There are a lot of other features usable with this engine, but they don't interest us right now so I will not describe them in detail. However, if you are interested, you can take a look at the official website for more details on the Box2D features (http://box2d.org/about/).

It's important to note that Box2D uses meters, kilograms, seconds, and radians...
