//下面分了几个main函数，打开相应的main函数即可使用，使用代码替换自己的工程图片。
//代码实现功能：类似泡泡龙小游戏的功能.
//开发环境：Code::blocks 10.05
//Note:使用前需配置SDL2.0在IDE的使用，细节参考博主的点击打开链接#include <stdio.h>#include <stdlib.h>#include <stdbool.h>#include <SDL2/SDL.h>#include <SDL2/SDL_image.h>int main1(int argc, char *argv[]){ SDL_Init(SDL_INIT_VIDEO); SDL_Window *window = SDL_CreateWindow("sdl", 100,100, 800,600, SDL_WINDOW_SHOWN); SDL_Surface *surface =SDL_GetWindowSurface(window);// SDL_Surface *image =IMG_Load("test2.png");// SDL_BlitSurface(image,NULL,surface,NULL); SDL_Surface *face1 =SDL_LoadBMP("test.bmp"); SDL_Surface *face2 =IMG_Load("test2.png");// SDL_BlitSurface(face1,NULL,surface,NULL); SDL_Rect rect; rect.x=10; rect.y=10; SDL_Event event; bool flag; while(flag==false){ while(SDL_PollEvent(&event)){ if(event.type == SDL_QUIT){ flag=true; } else if(event.type == SDL_MOUSEBUTTONDOWN){ if(event.button.button==SDL_BUTTON_LEFT){ SDL_BlitSurface(face1,NULL,surface,&rect); SDL_UpdateWindowSurface(window); printf("left\n"); } else if(event.button.button==SDL_BUTTON_RIGHT) { SDL_BlitSurface(face2,NULL,surface,&rect); SDL_UpdateWindowSurface(window); printf("right\n"); } printf("clicked\n"); } else if(event.type == SDL_KEYDOWN){ if(event.key.keysym.sym==SDLK_UP) { rect.y=rect.y-10; printf("SDLK_UP\n"); } else if(event.key.keysym.sym==SDLK_DOWN) { rect.y=rect.y+10; printf("SDLK_DOWN\n"); } else if(event.key.keysym.sym==SDLK_LEFT) { rect.x=rect.x-10; printf("SDLK_LEFT\n"); } else if(event.key.keysym.sym==SDLK_RIGHT) { rect.x=rect.x+10; printf("SDLK_RIGHT\n"); } SDL_BlitSurface(face2,NULL,surface,&rect); SDL_UpdateWindowSurface(window); SDL_FillRect(surface,NULL,0); } } } SDL_UpdateWindowSurface(window); SDL_Delay(2000); SDL_FreeSurface(surface); SDL_DestroyWindow(window); SDL_Quit(); return 0;}/*********************************2*************************************************/int main2(int argc, char *argv[]){ SDL_Init(SDL_INIT_VIDEO); SDL_Window *window = SDL_CreateWindow("hello",100,100, 800,710, SDL_WINDOW_SHOWN ); SDL_Surface *surface=SDL_GetWindowSurface(window); SDL_Surface *cat = SDL_LoadBMP("test.bmp"); SDL_Rect rect; rect.x=0; rect.y=0; SDL_Event event; bool quit =true; while(quit ==true){ while(SDL_PollEvent(&event)){ if(event.type==SDL_QUIT) { quit =false; } else if(event.type==SDL_MOUSEMOTION) { rect.x=event.motion.x-(cat->w/2); rect.y=event.motion.y-(cat->h/2); SDL_FillRect(surface,NULL,0); SDL_BlitSurface(cat,NULL,surface,&rect); printf("x=%d,y=%d\n",rect.x,rect.y); SDL_UpdateWindowSurface(window); } } } SDL_UpdateWindowSurface(window); SDL_FreeSurface(cat); SDL_DestroyWindow(window); SDL_Quit(); return 0;}/*****************************************3****************************************************/SDL_Rect rect;bool MoveDown=true;bool MoveLeft =true;void UpdataPostion(){ if(MoveLeft==true) { rect.x++; if(rect.x>=800-100) { MoveLeft=false; } } else { rect.x--; if(rect.x<=0) { MoveLeft=true; } } if(MoveDown==true) { rect.y++; if(rect.y+rect.h>=700) { MoveDown=false; } } else { rect.y--; if(rect.y<=0) { MoveDown=true; } }}int main3(int argc, char *argv[]){ SDL_Init(SDL_INIT_VIDEO); SDL_Window *window = SDL_CreateWindow("hello",100,100, 800,700, SDL_WINDOW_SHOWN ); SDL_Renderer *rend =SDL_CreateRenderer(window,-1,SDL_RENDERER_ACCELERATED); SDL_RenderClear(rend); SDL_Surface *catSurface = SDL_LoadBMP("test.bmp"); SDL_Texture *cat =SDL_CreateTextureFromSurface(rend,catSurface); SDL_Event event; rect.x=0; rect.y=0; rect.h=100; rect.w=100; bool quit =true; while(quit ==true){ while(SDL_PollEvent(&event)){ if(event.type==SDL_QUIT) { quit =false; } } UpdataPostion(); SDL_Delay(5); SDL_RenderCopy(rend,cat,NULL,&rect); SDL_RenderPresent(rend); } SDL_UpdateWindowSurface(window); SDL_FreeSurface(cat); SDL_DestroyWindow(window); SDL_Quit(); return 0;}/*********************************4************************************************/int main(int argc,char *argv[]) { SDL_Init(SDL_INIT_VIDEO); SDL_Window *window=SDL_CreateWindow("test3",100,100, 800,700, SDL_WINDOW_SHOWN); SDL_Renderer *render =SDL_CreateRenderer(window,-1,SDL_RENDERER_ACCELERATED); SDL_Surface *image =IMG_Load("move.png"); SDL_SetColorKey(image,SDL_TRUE,SDL_MapRGB(image->format,255,255,255)); SDL_Texture *texture =SDL_CreateTextureFromSurface(render,image); SDL_Event event; SDL_Rect postion; postion.x=0; postion.y=0; postion.w=image->w/5; postion.h=image->h/2; SDL_Rect clips[8]; int i,j; int ImgWidth =image->w/5; int ImgHeight =image->h/2; for(j=0;j<2;j++) { for(i=0;i<5;i++) { clips[j*5+i].x=0; clips[j*5+i].y=j*5+i*ImgWidth; clips[j*5+i].w=ImgWidth; clips[j*5+i].h=ImgHeight; } } bool quit =true; while(quit ==true){ while(SDL_PollEvent(&event)){ if(event.type==SDL_QUIT) { quit =false; } } SDL_RenderClear(render); SDL_RenderCopy(render,texture,&clips[j*5+i],&postion); SDL_RenderPresent(render); j=(j+1)%2; /*省事，代替if语句，代码更好看*/ i=(i+1)%5; postion.x++; SDL_Delay(500); } SDL_DestroyWindow(window); SDL_Quit(); return 0;}
