继续分享pygame有趣的技术知识,欢迎往下看。
一、先搭个架子
(一)黏贴背景图:
实现代码如下:
import pygame pygame.init() # 初始化pygame类 screen = pygame.display.set_mode((600, 600)) # 设置窗口大小 pygame.display.set_caption('幸运大转盘') # 设置窗口标题 tick = pygame.time.Clock() fps = 10 # 设置刷新率,数字越大刷新率越高 # 方法一 # bg = pygame.image.load("./幸运大转盘.png").convert() # 方法二 picture = pygame.transform.scale(pygame.image.load("./幸运大转盘.png"), (600, 600)) bg=picture.convert() while True: for event in pygame.event.get(): if event.type == pygame.QUIT: sys.exit() # screen.fill((255, 255, 0)) # 设置背景为白色 screen.blit(bg, (0, 0)) tick.tick(fps) pygame.display.flip() # 刷新窗口
(二)增加中间的圈圈
核心代码:
pygame.draw.circle(screen,(255,255,0),(300,300),50)
代码解释:
绘制圆形方法:pygame.draw.circle(Surface, color, pos , raduis, width)
其中:
- Surfuce参数: 传入需要在该Surface对象上绘制圆形的Surface对象
- color参数: 需要绘制圆形的线的颜色,传入一个rgb三原色元组
- pos参数:圆心的坐标
- raduis 表示圆的半径
- width参数:表示绘制圆的线的宽度,当为0时,圆内全部被填充
效果图:
相关代码如下:
import pygame pygame.init() # 初始化pygame类 screen = pygame.display.set_mode((600, 600)) # 设置窗口大小 pygame.display.set_caption('幸运大转盘') # 设置窗口标题 tick = pygame.time.Clock() fps = 10 # 设置刷新率,数字越大刷新率越高 # 方法一 # bg = pygame.image.load("./幸运大转盘.png").convert() # 方法二 picture = pygame.transform.scale(pygame.image.load("./幸运大转盘.png"), (600, 600)) bg=picture.convert() while True: for event in pygame.event.get(): if event.type == pygame.QUIT: sys.exit() # screen.fill((255, 255, 0)) # 设置背景为白色 screen.blit(bg, (0, 0)) pygame.draw.circle(screen,(255,255,0),(300,300),50) tick.tick(fps) pygame.display.flip() # 刷新窗口
(三)让大转盘自己动起来
核心代码:
newbg = pygame.transform.rotate(bg, angle) newRect = newbg.get_rect(center=(300,300)) angle -= 1 screen.blit(newbg, newRect)
运行效果:
相关代码如下:
import pygame pygame.init() # 初始化pygame类 screen = pygame.display.set_mode((600, 600)) # 设置窗口大小 pygame.display.set_caption('幸运大转盘') # 设置窗口标题 tick = pygame.time.Clock() fps = 10 # 设置刷新率,数字越大刷新率越高 # 方法一 # bg = pygame.image.load("./幸运大转盘.png").convert() # 方法二 picture = pygame.transform.scale(pygame.image.load("./幸运大转盘.png"), (600, 600)) bg=picture.convert() angle = 0 while True: for event in pygame.event.get(): if event.type == pygame.QUIT: sys.exit() # screen.fill((255, 255, 0)) # 设置背景为白色 newbg = pygame.transform.rotate(bg, angle) newRect = newbg.get_rect(center=(300,300)) angle -= 1 screen.blit(newbg, newRect) # screen.blit(bg, (0, 0)) pygame.draw.circle(screen,(255,255,0),(300,300),50) tick.tick(fps) pygame.display.flip() # 刷新窗口
二、再加个指针,幸运的小指针
(一)小指针不动,转盘动
运行效果:
相关代码如下:
import pygame pygame.init() # 初始化pygame类 screen = pygame.display.set_mode((600, 600)) # 设置窗口大小 pygame.display.set_caption('幸运大转盘') # 设置窗口标题 tick = pygame.time.Clock() fps = 10 # 设置刷新率,数字越大刷新率越高 picture = pygame.transform.scale(pygame.image.load("./幸运大转盘.png"), (600, 600)) bg=picture.convert() picture = pygame.transform.scale(pygame.image.load("./hand.png"), (30, 230)) hand = picture.convert_alpha() angle = 0 while True: for event in pygame.event.get(): if event.type == pygame.QUIT: sys.exit() newbg = pygame.transform.rotate(bg, angle) newRect = newbg.get_rect(center=(300,300)) angle -= 1 screen.blit(newbg, newRect) newRect = hand.get_rect(center=(300,150)) screen.blit(hand,newRect) pygame.draw.circle(screen,(255,255,0),(300,300),50) tick.tick(fps) pygame.display.flip() # 刷新窗口
(二)转盘不动,小指针动
思路:转盘指针的框的中心点按照圆的轨迹进行移动,然后在移动的过程中同步旋转对应的角度,这样就整个指针一方面移动,一方面转动。实现了自然的按照中心旋转的效果了。
1、先自己画指针矩形框的中心点移动
代码如下:
import pygame,sys import math pygame.init() # 初始化pygame类 screen = pygame.display.set_mode((600, 600)) # 设置窗口大小 pygame.display.set_caption('幸运大转盘') # 设置窗口标题 tick = pygame.time.Clock() fps = 100 # 设置刷新率,数字越大刷新率越高 picture = pygame.transform.scale(pygame.image.load("./幸运大转盘.png"), (600, 600)) bg=picture.convert() picture = pygame.transform.scale(pygame.image.load("./hand.png"), (30, 230)) hand = picture.convert_alpha() angle = 0 pos_list = [] while True: posx = 300+int(150*math.sin(135+angle/360)) posy = 300+int(150*math.cos(135+angle/360)) for event in pygame.event.get(): if event.type == pygame.QUIT: sys.exit() screen.blit(bg,(0,0)) pos_list.append((posx,posy)) for pos in pos_list: pygame.draw.circle(screen, (0, 0, 0), pos, 1) angle -= 2 pygame.draw.circle(screen,(255,255,0),(300,300),80) tick.tick(fps) pygame.display.flip() # 刷新窗口
效果如下:
2、增加指针转动(不完善的版本)
代码如下:
import pygame,sys import math pygame.init() # 初始化pygame类 screen = pygame.display.set_mode((600, 600)) # 设置窗口大小 pygame.display.set_caption('幸运大转盘') # 设置窗口标题 tick = pygame.time.Clock() fps = 100 # 设置刷新率,数字越大刷新率越高 picture = pygame.transform.scale(pygame.image.load("./幸运大转盘.png"), (600, 600)) bg=picture.convert() picture = pygame.transform.scale(pygame.image.load("./hand.png"), (30, 230)) hand = picture.convert_alpha() angle = 0 pos_list = [] while True: posx = 300+int(150*math.sin(135+angle/360)) posy = 300+int(150*math.cos(135+angle/360)) for event in pygame.event.get(): if event.type == pygame.QUIT: sys.exit() screen.blit(bg,(0,0)) pos_list.append((posx,posy)) for pos in pos_list: pygame.draw.circle(screen, (0, 0, 0), pos, 1) newhand = pygame.transform.rotate(hand, angle/6) # old_center = rect.center newRect = newhand.get_rect(center=(posx,posy)) screen.blit(newhand,newRect) pygame.draw.rect(screen, (255,0,0), newRect, 1) # if angle>-10: angle -= 2 print(angle) if angle < -2250: angle = 0 pygame.draw.circle(screen,(255,255,0),(300,300),80) tick.tick(fps) pygame.display.flip() # 刷新窗口
效果如下:
3、增加指针转动(修正版)
发现原来是math类库中的sin和cos函数传递的参数问题。
Math.Sin()里面的是弧度制。 如果是sin(30),就用Math.Sin(Math.PI*30.0/180.0);
因此主要修改的代码如下:
posx = 300 + int(150 * math.sin(angle * math.pi / 180)) posy = 300 - int(150 * math.cos(angle * math.pi / 180))
对应的运行效果如下:
想运行快点的话,就把angle的参数变大就好。
完整代码如下:
import pygame import math pygame.init() # 初始化pygame类 screen = pygame.display.set_mode((600, 600)) # 设置窗口大小 pygame.display.set_caption('幸运大转盘') # 设置窗口标题 tick = pygame.time.Clock() fps = 10 # 设置刷新率,数字越大刷新率越高 picture = pygame.transform.scale(pygame.image.load("./幸运大转盘.png"), (600, 600)) bg=picture.convert() picture = pygame.transform.scale(pygame.image.load("./hand.png"), (30, 230)) hand = picture.convert_alpha() angle = 0 while True: posx = 300 + int(150 * math.sin(angle * math.pi / 180)) posy = 300 - int(150 * math.cos(angle * math.pi / 180)) print(posx, posy, math.sin(angle * math.pi / 180)) for event in pygame.event.get(): if event.type == pygame.QUIT: sys.exit() screen.blit(bg,(0,0)) newhand = pygame.transform.rotate(hand, -angle) newRect = newhand.get_rect(center=(posx,posy)) screen.blit(newhand,newRect) angle += 10 pygame.draw.circle(screen,(255,255,0),(300,300),50) tick.tick(fps) pygame.display.flip() # 刷新窗口
三、增加随时数算法,实现随机事件
直接借用了这个算法:
轮盘分为三部分: 一等奖, 二等奖和三等奖;
轮盘转的时候是随机的,
如果范围在[0,0.08)之间,代表一等奖,
如果范围在[0.08,0.3)之间,代表2等奖,
如果范围在[0.3, 1.0)之间,代表3等奖,
把该算法封装成函数,相关代码如下:
rewardDict = { '一等奖': (0, 0.03), '二等奖': (0.03, 0.2), '三等奖': (0.2, 1) } def rewardFun(): """用户的得奖等级""" # 生成一个0~1之间的随机数 number = random.random() # 判断随机转盘是几等奖 for k, v in rewardDict.items(): if v[0] <= number < v[1]: return k
四、增加开始函数
def start(): while True: for event in pygame.event.get(): # 处理退出事件 if event.type == pygame.QUIT: pygame.quit() sys.exit() elif event.type == pygame.KEYDOWN: if (event.key == pygame.K_ESCAPE): pygame.quit() sys.exit() else: return screen.blit(bg,(0,0)) newRect = hand.get_rect(center=(300,150)) screen.blit(hand,newRect) pygame.draw.circle(screen,(255,255,0),(300,300),50) textFont = pygame.font.Font("./font/font.ttf", 80) textSurface = textFont.render("go", True, (110, 55, 155)) screen.blit(textSurface, (270, 230)) pygame.display.update()
五、增加结束函数
def end(k): textFont = pygame.font.Font("./font/font.ttf", 50) textSurface = textFont.render("your awards is :%s" % k, True, (110, 55, 155)) screen.fill((155, 155, 0)) screen.blit(textSurface, (30, 230))
六、最终完整效果及代码
import pygame,sys import math import random pygame.init() # 初始化pygame类 screen = pygame.display.set_mode((600, 600)) # 设置窗口大小 pygame.display.set_caption('幸运大转盘') # 设置窗口标题 tick = pygame.time.Clock() fps = 10 # 设置刷新率,数字越大刷新率越高 picture = pygame.transform.scale(pygame.image.load("./幸运大转盘.png"), (600, 600)) bg=picture.convert() picture = pygame.transform.scale(pygame.image.load("./hand.png"), (30, 230)) hand = picture.convert_alpha() rewardDict = { 'first level': (0, 0.03), 'second level': (0.03, 0.2), 'third level': (0.2, 1) } def rewardFun(): """用户的得奖等级""" # 生成一个0~1之间的随机数 number = random.random() # 判断随机转盘是几等奖 for k, v in rewardDict.items(): if v[0] <= number < v[1]: return k def start(): while True: for event in pygame.event.get(): # 处理退出事件 if event.type == pygame.QUIT: pygame.quit() sys.exit() elif event.type == pygame.KEYDOWN: if (event.key == pygame.K_ESCAPE): pygame.quit() sys.exit() else: return screen.blit(bg,(0,0)) newRect = hand.get_rect(center=(300,150)) screen.blit(hand,newRect) pygame.draw.circle(screen,(255,255,0),(300,300),50) textFont = pygame.font.Font("./font/font.ttf", 80) textSurface = textFont.render("go", True, (110, 55, 155)) screen.blit(textSurface, (270, 230)) pygame.display.update() def middle(): angle = 0 while True: posx = 300 + int(150 * math.sin(angle * math.pi / 180)) posy = 300 - int(150 * math.cos(angle * math.pi / 180)) print(posx, posy, math.sin(angle * math.pi / 180)) for event in pygame.event.get(): if event.type == pygame.QUIT: sys.exit() screen.blit(bg,(0,0)) newhand = pygame.transform.rotate(hand, -angle) newRect = newhand.get_rect(center=(posx,posy)) screen.blit(newhand,newRect) pygame.draw.circle(screen,(255,255,0),(300,300),50) angle += 10 if angle > 500: k = rewardFun() end(k) tick.tick(fps) pygame.display.flip() # 刷新窗口 def end(k): textFont = pygame.font.Font("./font/font.ttf", 50) textSurface = textFont.render("your awards is :%s" % k, True, (110, 55, 155)) screen.fill((155, 155, 0)) screen.blit(textSurface, (30, 230)) if __name__ == '__main__': start() middle()
运行效果如下:
