In-Depth Information

It renders it's graphics.
2.
It handles it's movement trajectories and other physics.
3.

as part of it's own lifecycle.
4.

Explosion

1.
It loads it's graphics.

Decoupling Using Component Pattern
Best design separates concerns in code so that everything has it's own place, and every
class handles only one thing. Let's try splitting up
Tank
class into components that handle
specific domains:
Decoupled Tank
We will introduce
GameObject
class will contain shared functionality for all game
objects (
Tank
,
Bullet
,
Explosion
), each of them would have it's own set of
components. Every component will have it's parent object, so it will be able to interact with
it, change it's attributes, or possibly invoke other components if it comes to that.
