Python游戏-实现键盘控制功能

要想实现键盘控制作用，就需要给游戏键盘监听事件  
利用pygame模块的key.get\_pressed()方法，来检测按键是否按下

key\_press =pygame.key.get\_pressed()  
if not key\_press\[K\_UP\] and ball.rect.bottom < height:  
ball.movedown()  
elif key\_press\[K\_UP\] and ball.rect.top>0:  
ball.moveup()  
1  
2  
3  
4  
5  
实现效果  
游戏中，当按下上键时游戏对象就往上移动，一松开按键，游戏对象就往下降

完整代码  
import pygame  
from pygame.locals import \*  
from sys import exit

pygame.init() \#进行初始化  
bgsize = width,height = 1000,600  
pygame.display.set\_mode(bgsize)  
pygame.display.set\_caption('进击的蜘蛛')  
bg=(0,0,0) \#设置背景颜色  
turtl = pygame.image.load('D:\\QQ\\MobileFile/spride.png')  
ball\_image = pygame.transform.scale(turtl,(width//10,height//10)) \#对图片进行缩放  
screen = pygame.display.get\_surface()  
class Ball(pygame.sprite.Sprite):  
def \_\_init\_\_(self,up\_speed,down\_speed):  
pygame.sprite.Sprite.\_\_init\_\_(self)  
self.up\_speed = up\_speed  
self.down\_speed = down\_speed  
self.image = ball\_image  
self.rect = self.image.get\_rect()  
self.rect.top = 0  
self.rect.left =(width-self.image.get\_width())//2  
def moveup(self):  
self.rect.top -=self.up\_speed

def movedown(self):  
self.rect.top +=self.down\_speed

ball = Ball(6,4)  
clock = pygame.time.Clock()  
while 1:  
for event in pygame.event.get():  
if event.type == QUIT:  
exit()

key\_press =pygame.key.get\_pressed()  
if not key\_press\[K\_UP\] and ball.rect.bottom < height:  
ball.movedown()  
elif key\_press\[K\_UP\] and ball.rect.top>0:  
ball.moveup()  
screen.fill(bg)  
screen.blit(ball\_image,ball.rect)  
clock.tick(25)  
pygame.display.flip() \#将更新显示到屏幕上
