本文详细介绍了使用C语言和Win32 API实现贪吃蛇和俄罗斯方块游戏的方法，包括游戏核心函数的设计与消息处理流程。贪吃蛇游戏涉及蛇的创建、移动、增长及苹果生成等功能；俄罗斯方块则涵盖方块下落、左右移动、旋转及行消除等机制。

1.复习贪吃蛇

1.贪吃蛇所包括的函数

基于C语言的Win32应用程序

void CreateApple()
void ShowApple()
void CreateSnake()
void ShowSnake()
void SnakeMove();
bool IsEatApple()
void GrowUp()
bool IsGameOve()

消息处理函数

WndProc()
{
case WM_CREATE:
	CreateSnake()
	CreateApple()
	break;

case WM_PAINT:
	ShowSnake()
	ShowApple()
	break;

case WM_TIMER:
	SnakeMove()
	if( IsEatApple() == true)
		GrowUp()
	if( IsGameOve() == true)
		MessageBox()
	break;

case WM_KEYDOWN:
	FX = ...	
	break;

}

2.俄罗斯方块所包含的函数

void CreateBackSqaure()
void CreateMoveSquare()
vodi ShowBackSuqare()
void ShowMoveSquare();
void DownMove()
void LeftMove()
void RightMove()
void ChangeStyle()
bool IsDownMove()
bool IsLeftMove()
bool IsRightMove()
bool IsChangeStyle()
void ReceiveSquare()
void DeleteLine()
bool IsGameOver()

消息处理函数

WndProc()
{
case WM_CREATE:
	CreateBackSqaure()
	CreateMoveSquare()
	break;

case WM_PAINT:
	ShowBackSuqare()
	ShowMoveSquare()
	break;

case WM_TIMER:
	if(IsDownMove() == ture)
	{
		DownMove()
	}
	else
	{
		ReceiveSquare();
		DeleteLine();
		if(IsGameOver)
		{
			.....
		}
	}
	break;

case WM_KEYDOWN:
	if( IsLeftMove() )
		LeftMove
	..
	..
	break;

}

2.游戏壳

1.用来作为模板类，可以进行多次扩展和复用

3.补全参数

GameApp.h头文件
