windows下用mingw32+sdl进行简单2d游戏开发（c语言）

本文主要是介绍windows下用mingw32+sdl进行简单2d游戏开发（c语言），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1、下载sdl库：http://www.libsdl.org/release/SDL-devel-1.2.15-mingw32.tar.gz

2、下载sdl_image库： http://www.libsdl.org/projects/SDL_image/release/SDL_image-devel-1.2.12-VC.zip

3、在mingw32/include下建立SDL文件夹。把sdl库include中的文件全部copy到这里

4、把sdl的lib下文件全部copy到mingw32的lib下

5、把sdl_image库中的inlcude/sdl_image.h放到刚才建立的文件夹下

6、把sdl_image库中的lib中的dll文件全部copy到mingw32d的lib中

7、把sdl_imagelib中的dll和sdl中的sdl.dll放到你编译的exe文件目录

8、编译指令

gcc -o demo4.exe(输出文件名) demo4.c(源文件名) -lmingw32 -lSDL_image -lSDLmain -lSDL

测试代码（请在该目录放一个tt.png图片，随便。自己网上找了）：

#include<stdio.h>
#include "SDL/SDL.h"
#include "SDL/SDL_image.h"
SDL_Surface *screen;
void video_init(){  //游戏图形模式初始化
if(SDL_Init(SDL_INIT_VIDEO)){
fprintf(stderr,"Can't init SDL:%s\n",SDL_GetError());
exit(1);
}
screen=SDL_SetVideoMode(640,480,16,SDL_SWSURFACE);
if(screen==NULL){
fprintf(stderr,"Can't set mode 640x480:%s\n",SDL_GetError());
exit(1);
}
atexit(SDL_Quit);
SDL_ShowCursor(0);//关闭鼠标显示
}
SDL_Surface *loadIMG(const char *fileName){
SDL_Surface *img;
img = IMG_Load(fileName);
if(img == NULL)  
{  
fprintf(stderr,"Could not load %s: %s",fileName,SDL_GetError());  
exit(1);  
}  
return img;  
}
SDL_Surface *loadBMP(char *fileName)            //加载bmp图片  
{  
SDL_Surface *bmp;  
bmp = SDL_LoadBMP(fileName);  
if(bmp == NULL)  
{  
fprintf(stderr,"Could not load %s: %s",fileName,SDL_GetError());  
exit(1);  
}  
return bmp;  
}  
int main(int argc, char* argv[]){
if(SDL_Init(SDL_INIT_EVERYTHING)==-1){
printf("error..\n");
}else{
printf("ok\n");
video_init();
SDL_Surface *img;
img=loadIMG("tt.png");
while (1){
// Poll for events, and handle the ones we care about.
SDL_Rect dest;
dest.x=100;
dest.y=100;
dest.w=200;
dest.h=200;
SDL_Color color;
color.r=255;
color.g=0;
color.b=0;
SDL_FillRect(screen, &screen->clip_rect, SDL_MapRGB(screen->format,0xFF,0xFF,0xFF));
SDL_FillRect(screen, &dest, SDL_MapRGB(screen->format,0,0,0xFF));
dest.x=200;
dest.y=200;
dest.w=200;
dest.h=200;
SDL_BlitSurface(img, &screen->clip_rect, screen,&dest);
SDL_Flip(screen);
SDL_Event event;
while (SDL_PollEvent(&event)){
if(event.type==SDL_KEYDOWN){
int key = event.key.keysym.sym;
printf("%d\n",key);
if(key==SDLK_ESCAPE){
printf("%d\n",1000);
SDL_Quit();
exit(1);
}else if(key==SDLK_UP){
printf("up\n");
}else if(key==SDLK_DOWN){
printf("down\n");
}else if(key==SDLK_LEFT){
printf("left\n");
}else if(key==SDLK_RIGHT){
printf("right\n");
}
}else if(event.type==SDL_QUIT){
printf("%d\n",1000);
SDL_Quit();
exit(1);
}
}
}
}
return 0;
}
