C + + flying game development Log

Design ideas:
Console mode
Initialization
Set up the screen, initialize the data
Game process:
1. Get the action
2. Modify the data
3. Update screen
End:
Close screen, delete dynamically allocate data

4.29 Days

Create a game background to enable the aircraft to move operations, to achieve bullet flight

4.30 days

Achieve game data management, aircraft shooting down animation, random enemy aircraft

The feeling class is poorly written, resulting in a lot of duplicated code. decided to refactor.
