C++ 游戏开发入门：用 C++ 制作一个简单的贪吃蛇游戏

"C++ 是一种强大的编程语言，非常适合用于游戏开发。下面是一个简单的 C++ 游戏的例子，展示了如何使用 C++ 来制作一个简单的控制台游戏：\n\ncpp\n#include <iostream>\n#include <conio.h>\n\nusing namespace std;\n\nbool gameOver;\nconst int width = 20;\nconst int height = 20;\nint x, y, fruitX, fruitY, score;\nint tailX[100], tailY[100];\nint nTail;\nenum eDirection { STOP = 0, LEFT, RIGHT, UP, DOWN };\neDirection dir;\n\nvoid Setup()\n{\n gameOver = false;\n dir = STOP;\n x = width / 2;\n y = height / 2;\n fruitX = rand() % width;\n fruitY = rand() % height;\n score = 0;\n}\n\nvoid Draw()\n{\n system("cls");\n for (int i = 0; i < width + 2; i++)\n cout << "#";\n cout << endl;\n\n for (int i = 0; i < height; i++)\n {\n for (int j = 0; j < width; j++)\n {\n if (j == 0)\n cout << "#";\n if (i == y && j == x)\n cout << "O";\n else if (i == fruitY && j == fruitX)\n cout << "F";\n else\n {\n bool printTail = false;\n for (int k = 0; k < nTail; k++)\n {\n if (tailX[k] == j && tailY[k] == i)\n {\n cout << "o";\n printTail = true;\n }\n }\n if (!printTail)\n cout << " ";\n }\n if (j == width - 1)\n cout << "#";\n }\n cout << endl;\n }\n\n for (int i = 0; i < width + 2; i++)\n cout << "#";\n cout << endl;\n cout << "Score:" << score << endl;\n}\n\nvoid Input()\n{\n if (_kbhit())\n {\n switch (_getch())\n {\n case 'a':\n dir = LEFT;\n break;\n case 'd':\n dir = RIGHT;\n break;\n case 'w':\n dir = UP;\n break;\n case 's':\n dir = DOWN;\n break;\n case 'x':\n gameOver = true;\n break;\n }\n }\n}\n\nvoid Logic()\n{\n int prevX = tailX[0];\n int prevY = tailY[0];\n int prev2X, prev2Y;\n tailX[0] = x;\n tailY[0] = y;\n for (int i = 1; i < nTail; i++)\n {\n prev2X = tailX[i];\n prev2Y = tailY[i];\n tailX[i] = prevX;\n tailY[i] = prevY;\n prevX = prev2X;\n prevY = prev2Y;\n }\n\n switch (dir)\n {\n case LEFT:\n x--;\n break;\n case RIGHT:\n x++;\n break;\n case UP:\n y--;\n break;\n case DOWN:\n y++;\n break;\n default:\n break;\n }\n\n if (x >= width)\n x = 0;\n else if (x < 0)\n x = width - 1;\n\n if (y >= height)\n y = 0;\n else if (y < 0)\n y = height - 1;\n\n for (int i = 0; i < nTail; i++)\n {\n if (tailX[i] == x && tailY[i] == y)\n gameOver = true;\n }\n\n if (x == fruitX && y == fruitY)\n {\n score += 10;\n fruitX = rand() % width;\n fruitY = rand() % height;\n nTail++;\n }\n}\n\nint main()\n{\n Setup();\n while (!gameOver)\n {\n Draw();\n Input();\n Logic();\n }\n return 0;\n}\n\n\n这个例子是一个简单的贪吃蛇游戏，使用了 C++ 语言来实现游戏的逻辑。游戏中使用了控制台窗口来展示游戏画面，并通过键盘输入来控制贪吃蛇的移动方向。游戏的规则是控制贪吃蛇吃掉水果，每吃一个水果得 10 分，当贪吃蛇碰到边界或自己的身体时游戏结束。游戏通过不断更新贪吃蛇的位置和水果的位置来实现游戏的动态效果。你可以根据自己的需求修改和扩展这个例子，创造出更加复杂和有趣的游戏！\n
