Python plane war game

Python creates a simple plane war game, in which the player needs to control the plane to fire bullets to destroy the enemy plane while avoiding the attack of the enemy plane.

analyze:

1. First, import the necessary libraries, including pygame and the random library random.
2. Initialize pygame and create a 480x720 window.
3. Load the desired background, enemy plane, main character plane and bullet pictures.
4. Initialize some variables, including the score, the position of the protagonist plane, the position of the enemy plane, the position and speed of the bullet, the explosion mark, and the movement speed of the enemy plane.
5. Enter the game loop and handle events, including window closing, key presses and releases, etc.
6. In the event processing, the movement of the protagonist's aircraft and the firing of bullets are controlled according to the buttons.
7. In the drawing part, the background image and character image are drawn to the screen.
8. In the collision detection part, it is detected whether the bullet collides with the enemy plane, and scores are given according to the probability.
9. If the bullet collides with an enemy, it will trigger an explosion effect and delete the enemy.
10. Repeat the game loop until the window is closed.

operation result

1. Start the game window and display the background image.
2. Players can use the left and right arrow keys to control the movement of the protagonist's aircraft, and press the space bar to fire bullets.
3. The enemy will automatically move down and fire bullets up.
4. When the bullet collides with the enemy plane, it will trigger the explosion effect, increase the score, and delete the enemy plane.
5. If the protagonist's plane is hit by an enemy plane or a bullet, the game is over.
6. After the game is over, the player's final score is displayed.
