c语言贪吃蛇代码求注释
在论坛上看到过这段代码,有一些不懂的,还请高手帮帮忙程序代码:
if(kbhit()) { c1=getch(); if(c1==27) break; if(c!='d' && c1=='a') c=c1; else if(c!='a' && c1=='d') c=c1; else if(c!='w' && c1=='s') c=c1; else if(c!='s' && c1=='w') c=c1; } pt=rear; while(pt!=head ) { pt->x=pt->pre->x; pt->y=pt->pre->y; pt=pt->pre; } if(c=='d') { head->y+=1; if(head->y>=15) head->y-=15; } else if(c=='a') { head->y-=1; if(head->y<0) head->y+=15; } else if(c=='w') { head->x-=1; if(head->x<0) head->x+=15; } else if(c=='s') { head->x+=1; if(head->x>=15) head->x-=15; } pt=head->next; while(pt!=NULL) { if(head->x==pt->x && head->y==pt->y) { gameover=1; break; } pt=pt->next ; } if(gameover==1) break; system("cls"); printf(" ───────────────\n"); for(i=0;i<15;i++) { printf("│"); for(j=0;j<15;j++) { flag=0; pt=head; while(pt!=NULL) { if(i==pt->x && j==pt->y) { if(pt==head) printf("■"); else printf("□"); flag=1; break; } pt=pt->next; } if(flag==0) { if(i==food.x && j==food.y) { putchar(food.c); putchar(food.c); continue; } printf(" "); } } printf("│"); putchar('\n'); } printf(" ───────────────\n"); _sleep(200); } if(gameover==1) puts("game over!\n"); getch(); }
