本系列文章基于SDL2.0及Visual C_

#include "SDL.h"/******************************************************************************game strtucture: initialise | | ----get input | | | | | do physics | | | | ----

#include "SDL.h"class Game2{public: Game2():m_pWindow(NULL),m_pRenderer(NULL), m_bRunning(false){}; ~Game2(){}; bool init(const char* title, int xpos, int ypos, int width, int height, int flag

#include "SDL.h"struct { Uint8 *sound; // pointer to wave data Uint32 soundlen; // length of wave data int soundpos; // current play position}wave;int done;static voi

#include "SDL.h"#include #include void example04(){    SDL_Window        *pWindow = NULL;    SDL_Renderer    *pRenderer = NULL;    SDL_Texture        *pTexture;    SDL_Rect

这篇文章实际和学习笔记3和4差不多，未来需要深入理解window, render, texture, surface等概念。#include "SDL.h"struct{ Uint32 pixformat; int w, h; Uint8 *data;}frame;int screen_width = 0;int screen_height

定时器API(timer.h):1. Uint32 SDL_GetTicks(): 获取从SDL库初始化(定时器模块初始化)开始到当前的运行时间(ms);2. Uint64 SDL_GetPerformanceCounter(): 获取高精度定时器的当前值;3. Uint64 SDL_GetPerformanceFrequency(): 获取高进度定时器频率(每秒钟高精度定时器的次数)
