I. name of experiment project
Aircraft Wars
II. Functional description of the experimental project (in its own language)
1. Use the mouse to control the aircraft movement.
2. Launch bullets: press the left mouse button to launch bullets.
3. Add enemy aircraft: the enemy aircraft will automatically move downward and reappear after disappearing from the border,
4. Judge the victory or defeat: add points if the bullet hits the enemy aircraft, or the game fails if the enemy aircraft hits our aircraft, and increase the picture effect of the explosion of our aircraft.
5. Increase the sound effect: increase the background music, the sound effect of firing bullets, the sound effect of aircraft explosion, and the score reward sound effect.

Vi. experiment summary (put forward problems + Solutions + thoughts)
Why does the game get stuck every time before the sound effect?
Because it is to compile and run the game source code directly, try to build the game source code group into an exe program and run it. The problem is solved.
It's not easy to play a game. I need to study more carefully. Step by step, when the game runs perfectly, I still have a sense of achievement.
