一、项目效果演示

QQ录屏20240122164409

二、游戏玩法介绍

        本项目为娱乐项目非原创，主要玩法即通过电脑摄像头检测手部信息，来实现挡板的移动控制，可以一人或者2人参与游戏，调节代码可以控制球飞行速度。

        注意：本小游戏所有环境配置都会给出，无需其他复杂操作代码也简单，只要按照步骤来一定可以自己运行在PC端。
 

三、游戏所需python环境介绍和安装

        首先python的版本此处选择为3.7.7（其余版本相差不大的都可）

        然后，我们所需要下载的环境如下所示，你可以将其存为txt格式直接在终端输入(具体格式如下)：

pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple
absl-py==2.1.0
attrs==23.2.0
cvzone==1.6.1
cycler==0.11.0
flatbuffers==23.5.26
fonttools==4.38.0
importlib-metadata==6.7.0
kiwisolver==1.4.5
matplotlib==3.5.3
mediapipe==0.9.0.1
numpy==1.21.6

四、代码编写和介绍

1、导入所需库和加载图像信息

  1. import cv2
  2. import cvzone
  3. from cvzone.HandTrackingModule import HandDetector
  4. import numpy as np
  5.  
  6. cap = cv2.VideoCapture(0)
  7. cap.set(3, 1280)
  8. cap.set(4, 720)
  9.  
  10. # Importing all images
  11. imgBackground = cv2.imread("Resources/Background.png")
  12. imgGameOver = cv2.imread("Resources/gameOver.png")
  13. imgBall = cv2.imread("Resources/Ball.png", cv2.IMREAD_UNCHANGED)
  14. imgBat1 = cv2.imread("Resources/bat1.png", cv2.IMREAD_UNCHANGED)
  15. imgBat2 = cv2.imread("Resources/bat2.png", cv2.IMREAD_UNCHANGED)

 2、捕捉手部信息并计算小球运动数据

speedX：调节小球X轴运动速度

speedY：调节小球Y轴运动速度

ballPos：调节小球初始位置

  1. # Hand Detector
  2. detector = HandDetector(detectionCon=0.8, maxHands=2)
  3.  
  4. # Variables
  5. ballPos = [100, 100]
  6. speedX = 15
  7. speedY = 15
  8. gameOver = False
  9. score = [0, 0]
  10.  
  11. while True:
  12.     _, img = cap.read()
  13.     img = cv2.flip(img, 1)
  14.     imgRaw = img.copy()
  15.  
  16.     # Find the hand and its landmarks
  17.     hands, img = detector.findHands(img, flipType=False)  # with draw
  18.  
  19.     # Overlaying the background image
  20.     img = cv2.addWeighted(img, 0.2, imgBackground, 0.8, 0)
  21.  
  22.     # Check for hands
  23.     if hands:
  24.         for hand in hands:
  25.             x, y, w, h = hand['bbox']
  26.             h1, w1, _ = imgBat1.shape
  27.             y1 = y - h1 // 2
  28.             y1 = np.clip(y1, 20, 415)
  29.  
  30.             if hand['type'] == "Left":
  31.                 img = cvzone.overlayPNG(img, imgBat1, (59, y1))
  32.                 if 59 < ballPos[0] < 59 + w1 and y1 < ballPos[1] < y1 + h1:
  33.                     speedX = -speedX
  34.                     ballPos[0] += 30
  35.                     score[0] += 1
  36.  
  37.             if hand['type'] == "Right":
  38.                 img = cvzone.overlayPNG(img, imgBat2, (1195, y1))
  39.                 if 1195 - 50 < ballPos[0] < 1195 and y1 < ballPos[1] < y1 + h1:
  40.                     speedX = -speedX
  41.                     ballPos[0] -= 30
  42.                     score[1] += 1
  43.  
  44.     # Game Over
  45.     if ballPos[0] < 40 or ballPos[0] > 1200:
  46.         gameOver = True
  47.  
  48.     if gameOver:
  49.         img = imgGameOver
  50.         cv2.putText(img, str(score[1] + score[0]).zfill(2), (585, 360), cv2.FONT_HERSHEY_COMPLEX,
  51.                     2.5, (200, 0, 200), 5)
  52.  
  53.     # If the game is not over, move the ball
  54.     else:
  55.  
  56.         # Move the Ball
  57.         if ballPos[1] >= 500 or ballPos[1] <= 10:
  58.             speedY = -speedY
  59.  
  60.         ballPos[0] += speedX
  61.         ballPos[1] += speedY
  62.  
  63.         # Draw the ball
  64.         img = cvzone.overlayPNG(img, imgBall, ballPos)
  65.  
  66.         cv2.putText(img, str(score[0]), (300, 650), cv2.FONT_HERSHEY_COMPLEX, 3, (255, 255, 255), 5)
  67.         cv2.putText(img, str(score[1]), (900, 650), cv2.FONT_HERSHEY_COMPLEX, 3, (255, 255, 255), 5)
  68.  
  69.     img[580:700, 20:233] = cv2.resize(imgRaw, (213, 120))

3、控制游戏开始和退出

  1. cv2.imshow("Image", img)
  2.     key = cv2.waitKey(1)
  3.     if key == ord('r'):
  4.         ballPos = [100, 100]
  5.         speedX = 15
  6.         speedY = 15
  7.         gameOver = False
  8.         score = [0, 0]
  9.         imgGameOver = cv2.imread("Resources/gameOver.png")
  10.     elif key == 27:  # Check for the ESC key
  11.         break
  12.  
  13. cap.release()
  14. cv2.destroyAllWindows()
