飛機大戰
前言
開始
獻上程式碼
from tkinter.messagebox import showinfo

base.geometry('0x0')
base.resizable(False,False)

return 程式碼剖析
from tkinter.messagebox import showinfo
from pygame.locals import *
import tkinter as tk
from random import *
import pygame
base = tk.Tk()
base.geometry('0x0')
base.resizable(False,False)
匯入庫及初始化
def intersect_p2f(p,f):
return pygame.Rect(f).collidepoint(*p)
def intersect_f2f(f1,f2):
return pygame.Rect(f1).colliderect(pygame.Rect(f2))
使用pygame.Rect物件提供的collide*方法檢查是否重疊。

WIDTH,HEIGHT = 480,640
scr = pygame.display.set_mode((WIDTH,HEIGHT))
bg = pygame.image.load('background.jpg')

初始化變數：
- 視窗長寬
- 視窗物件
- 5張圖片
- 敵方飛機列表
- 敵方子彈列表
- 己方飛機x軸座標
- 己方子彈列表
- 迴圈圈數
- 是否正在按左箭頭和右箭頭(
pygame.K_LEFT和pygame.K_RIGHT)
while(1):
for i in enemy_bullets:
if(intersect_p2f(i,((fighter_x, HEIGHT - 64),(fighter_x, HEIGHT - 64)))):
return score
for i in range(len(planes)):
if(i >= len(planes)):
break
for j in fighter_bullets:
if(intersect_p2f(j,(planes[i],(planes[i][0] + 64,planes[i][1] + 64)))):
planes.pop(i)
score += 10
進入遊戲迴圈，檢查飛機是否被射下：
- 己方飛機被敵方射下，遊戲結束(敵方子彈在我方飛機上)
- 敵方飛機被己方射下，加10分(我放子彈在敵方飛機上)
pygame.display.update()
scr.blit(bg,(0,0))
n = (n + 1) % 600
if(not n):
x = randint(0,WIDTH - 64)
y = randint(0,HEIGHT / 2)
planes.append((x,y))
elif(not n % 90):
for i in range(len(planes)):
enemy_bullets.append((planes[i][0] + 32, planes[i][1] + 64))
fighter_bullets.append((fighter_x + 32, HEIGHT - 64))
elif(not n % 8):
if(L_P and (not R_P)):
fighter_x = max(fighter_x - 5, 0)
if(R_P and (not L_P)):
fighter_x = min(fighter_x + 5, WIDTH - 64)
重新整理頁面並按照迴圈圈數執行：
- 每600次迴圈生成新的敵方飛機
- 每90次迴圈生成發射新的子彈(敵、我方)
- 每8次處理按下左箭頭和右箭頭一次。
for i in range(len(planes)):
planes[i] = (planes[i][0],planes[i][1] + 0.5)
scr.blit(plane_enemy,planes[i])
scr.blit(fighter, (fighter_x, HEIGHT - 64))
for i in range(len(enemy_bullets)):
if (i >= len(enemy_bullets)):
break
enemy_bullets[i] = (enemy_bullets[i][0],enemy_bullets[i][1] + 5)
if(enemy_bullets[i][1] >= WIDTH):
enemy_bullets.pop(i)
if (i >= len(enemy_bullets)):
break
scr.blit(enemy_bullet,enemy_bullets[i])
for i in range(len(fighter_bullets)):
if (i >= len(fighter_bullets)):
break
fighter_bullets[i] = (fighter_bullets[i][0],fighter_bullets[i][1] - 5)
if(fighter_bullets[i][1] <= 0):
fighter_bullets.pop(i)
if (i >= len(fighter_bullets)):
break
scr.blit(fighter_bullet,fighter_bullets[i])
敵方飛機自動移動0.5個畫素，子彈自動移動5個畫素，刪除出界的子彈。
for ev in pygame.event.get():
if(ev.type == QUIT):
exit()
elif(ev.type == KEYDOWN):
if(ev.key == K_LEFT):
L_P = True
elif(ev.key == K_RIGHT):
R_P = True
elif(ev.type == KEYUP):
if (ev.key == K_LEFT):
L_P = False
elif (ev.key == K_RIGHT):
R_P = False
當左箭頭(K_LEFT)被按下時將L_P(Left Pressed)跟改為True
當左箭頭(K_LEFT)被放開時將L_P(Left Pressed)跟改為False
當左箭頭(K_RIGHT)被按下時將R_P(Right Pressed)跟改為True
當又箭頭(K_RIGHT)被放開時將R_P(Right Pressed)跟改為False
if(__name__ == '__main__'):
while(1):
score = main()
showinfo('GAMEOVER!','GAMEOVER!score:%s'%score)
執行並提示gameover
