添加游戏资源
第一步:你好,兔子
# 1 - Import library import pygame from pygame.locals import * # 2 - Initialize the game pygame.init() width, height = 640, 480 screen=pygame.display.set_mode((width, height)) # 3 - Load images player = pygame.image.load("resources/images/dude.png") # 4 - keep looping through while 1: # 5 - clear the screen before drawing it again screen.fill(0) # 6 - draw the screen elements screen.blit(player, (100,100)) # 7 - update the screen pygame.display.flip() # 8 - loop through the events for event in pygame.event.get(): # check if the event is the X button if event.type==pygame.QUIT: # if it is quit the game pygame.quit() exit(0)
第二步:添加背景
grass = pygame.image.load("resources/images/grass.png") castle = pygame.image.load("resources/images/castle.png")
for x in range(width/grass.get_width()+1): for y in range(height/grass.get_height()+1): screen.blit(grass,(x*100,y*100)) screen.blit(castle,(0,30)) screen.blit(castle,(0,135)) screen.blit(castle,(0,240)) screen.blit(castle,(0,345 ))
第三步:让兔子能够移动
keys = [False, False, False, False]
playerpos=[100,100]
screen.blit(player, (100,100))
改成:
screen.blit(player, playerpos)
if event.type == pygame.KEYDOWN: if event.key==K_w: keys[0]=True elif event.key==K_a: keys[1]=True elif event.key==K_s: keys[2]=True elif event.key==K_d: keys[3]=True if event.type == pygame.KEYUP: if event.key==pygame.K_w: keys[0]=False elif event.key==pygame.K_a: keys[1]=False elif event.key==pygame.K_s: keys[2]=False elif event.key==pygame.K_d: keys[3]=False
# 9 - Move player if keys[0]: playerpos[1]-=5 elif keys[2]: playerpos[1]+=5 if keys[1]: playerpos[0]-=5 elif keys[3]: playerpos[0]+=5
第四步:让兔子转向
import math
然后,把#6部分的最后一行用一下代码替换:
# 6.1 - Set player position and rotation position = pygame.mouse.get_pos() angle = math.atan2(position[1]-(playerpos[1]+32),position[0]-(playerpos[0]+26)) playerrot = pygame.transform.rotate(player, 360-angle*57.29) playerpos1 = (playerpos[0]-playerrot.get_rect().width/2, playerpos[1]-playerrot.get_rect().height/2) screen.blit(playerrot, playerpos1)
第五步:射吧!兔子
acc=[0,0]
arrows=[]
arrow = pygame.image.load("resources/images/bullet.png")
现在,当玩家点击鼠标,就需要射出一支箭头。在#8部分加上以下代码:
if event.type==pygame.MOUSEBUTTONDOWN: position=pygame.mouse.get_pos() acc[1]+=1 arrows.append([math.atan2(position[1]-(playerpos1[1]+32),position[0]-(playerpos1[0]+26)),playerpos1[0]+32,playerpos1[1]+32])
# 6.2 - Draw arrows for bullet in arrows: index=0 velx=math.cos(bullet[0])*10 vely=math.sin(bullet[0])*10 bullet[1]+=velx bullet[2]+=vely if bullet[1]<-64 or bullet[1]>640 or bullet[2]<-64 or bullet[2]>480: arrows.pop(index) index+=1 for projectile in arrows: arrow1 = pygame.transform.rotate(arrow, 360-projectile[0]*57.29) screen.blit(arrow1, (projectile[1], projectile[2]))
第六部:獾,拿上武器!
badtimer=100 badtimer1=0 badguys=[[640,100]] healthvalue=194
badguyimg1 = pygame.image.load("resources/images/badguy.png") badguyimg=badguyimg1
# 6.3 - Draw badgers if badtimer==0: badguys.append([640, random.randint(50,430)]) badtimer=100-(badtimer1*2) if badtimer1>=35: badtimer1=35 else: badtimer1+=5 index=0 for badguy in badguys: if badguy[0]<-64: badguys.pop(index) badguy[0]-=7 index+=1 for badguy in badguys: screen.blit(badguyimg, badguy)
import random
最后,把一行代码添加到#4部分的while表达式后面:
badtimer-=1
# 6.3.1 - Attack castle badrect=pygame.Rect(badguyimg.get_rect()) badrect.top=badguy[1] badrect.left=badguy[0] if badrect.left<64: healthvalue -= random.randint(5,20) badguys.pop(index) # 6.3.3 - Next bad guy
第七部:獾与箭头的碰撞
#6.3.2 - Check for collisions index1=0 for bullet in arrows: bullrect=pygame.Rect(arrow.get_rect()) bullrect.left=bullet[1] bullrect.top=bullet[2] if badrect.colliderect(bullrect): acc[0]+=1 badguys.pop(index) arrows.pop(index1) index1+=1
第八步:添加健康值和时间的显示
# 6.4 - Draw clock font = pygame.font.Font(None, 24) survivedtext = font.render(str((90000-pygame.time.get_ticks())/60000)+":"+str((90000-pygame.time.get_ticks())/1000%60).zfill(2), True, (0,0,0)) textRect = survivedtext.get_rect() textRect.topright=[635,5] screen.blit(survivedtext, textRect)
上面的代码使用了PyGame默认的大小为24的字体。这个字体用来显示时间信息。
healthbar = pygame.image.load("resources/images/healthbar.png") health = pygame.image.load("resources/images/health.png")
接下来添加代码到#6.4部分后面:
# 6.5 - Draw health bar screen.blit(healthbar, (5,5)) for health1 in range(healthvalue): screen.blit(health, (health1+8,8))
第九步:赢或输
#10 - Win/Lose check if pygame.time.get_ticks()>=90000: running=0 exitcode=1 if healthvalue<=0: running=0 exitcode=0 if acc[1]!=0: accuracy=acc[0]*1.0/acc[1]*100 else: accuracy=0 # 11 - Win/lose display if exitcode==0: pygame.font.init() font = pygame.font.Font(None, 24) text = font.render("Accuracy: "+str(accuracy)+"%", True, (255,0,0)) textRect = text.get_rect() textRect.centerx = screen.get_rect().centerx textRect.centery = screen.get_rect().centery+24 screen.blit(gameover, (0,0)) screen.blit(text, textRect) else: pygame.font.init() font = pygame.font.Font(None, 24) text = font.render("Accuracy: "+str(accuracy)+"%", True, (0,255,0)) textRect = text.get_rect() textRect.centerx = screen.get_rect().centerx textRect.centery = screen.get_rect().centery+24 screen.blit(youwin, (0,0)) screen.blit(text, textRect) while 1: for event in pygame.event.get(): if event.type == pygame.QUIT: pygame.quit() exit(0) pygame.display.flip()
gameover = pygame.image.load("resources/images/gameover.png") youwin = pygame.image.load("resources/images/youwin.png")
gameover = pygame.image.load("resources/images/gameover.png") youwin = pygame.image.load("resources/images/youwin.png")
# 4 - keep looping through while 1: badtimer-=1
改成:
# 4 - keep looping through running = 1 exitcode = 0 while running: badtimer-=1
<ignore_js_op>
第十步:免费的音乐和声音效果
pygame.mixer.init()
然后在#3部分加载声音然后设置声音:
# 3.1 - Load audio hit = pygame.mixer.Sound("resources/audio/explode.wav") enemy = pygame.mixer.Sound("resources/audio/enemy.wav") shoot = pygame.mixer.Sound("resources/audio/shoot.wav") hit.set_volume(0.05) enemy.set_volume(0.05) shoot.set_volume(0.05) pygame.mixer.music.load(‘resources/audio/moonlight.wav‘) pygame.mixer.music.play(-1, 0.0) pygame.mixer.music.set_volume(0.25)
# section 6.3.1 after if badrect.left<64: hit.play() # section 6.3.2 after if badrect.colliderect(bullrect): enemy.play() # section 8, after if event.type==pygame.MOUSEBUTTONDOWN: shoot.play()
那接下来呢?
