Two players (you and the cpu) alternately pick a certain number of matches and the one, who takes the last match, loses. History: ------- V1.0 : 2003-07-22 First release of the game V1.1 : 2003-07-22 I Change the patterns definition in order to have a clean code V1.2 : 2003-07-30 Patch from JB that change: . the win and lose message . the BUTTON_STOP code . Add a test I suppress the exit variable I suppress or translates the comments which were in French I put min=1 at the of the main loop ( When there are 21 matches you can decide not to take a match. Later you are obliged to take at least one.) */ PLUGIN_HEADER /*Pattern for the game*/ static unsigned char smile[]={0x00, 0x11, 0x04, 0x04, 0x00, 0x11, 0x0E}; /* :-) */ static unsigned char cry[] ={0x00, 0x11, 0x04, 0x04, 0x00, 0x0E, 0x11}; /* :-( */ static unsigned char pattern3[]={0x15, 0x15, 0x15, 0x15, 0x15, 0x15, 0x15}; /*3 parts*/ static unsigned char pattern2[]={0x14, 0x14, 0x14, 0x14, 0x14, 0x14, 0x14}; /*2 parts*/ static unsigned char pattern1[]={0x10, 0x10, 0x10, 0x10, 0x10, 0x10, 0x10}; /*1 part*/ static unsigned char str[12]; /*String use to display the first line*/ static unsigned char hsmile,hcry,h1,h2; /*Handle for the new pattern*/ static bool end; /*If true game is finished*/ static struct plugin_api* rb; /*Display that the action it's impossible*/ static void impossible(void) { rb->lcd_puts(0,1,"Impossible!"); rb->sleep(HZ); return; } /*Display that the CPU lose :) */ static void lose(void) { rb->lcd_define_pattern(hsmile,smile); rb->snprintf(str,sizeof(str),"You Win!!%c",hsmile); rb->lcd_puts(0,1,str); end=true; rb->sleep(HZ*2); return; } /* Display that the CPU win :( */ static void win(void) { rb->lcd_define_pattern(hcry,cry); rb->snprintf(str,sizeof(str),"You Lose!!%c",hcry); rb->lcd_puts(0,1,str); end=true; rb->sleep(HZ*2); return; } /*Display the first line*/ static void display_first_line(int x) { int i; rb->snprintf(str,sizeof(str)," =%d",x); rb->lcd_define_pattern(h1,pattern3); for(i=0;ilcd_define_pattern(h2,pattern2); str[i]=h2; } if (x%3==1) { rb->lcd_define_pattern(h2,pattern1); str[i]=h2; } rb->lcd_puts(0,0,str); } /* Call when the program end */ static void nim_exit(void *parameter) { (void)parameter; /*Restore the old pattern*/ rb->lcd_unlock_pattern(h1); rb->lcd_unlock_pattern(h2); rb->lcd_unlock_pattern(hsmile); rb->lcd_unlock_pattern(hcry); /*Clear the screen*/ rb->lcd_clear_display(); } /* this is the plugin entry point */ enum plugin_status plugin_start(struct plugin_api* api, void* parameter) { int y,z,button; int x,v,min; bool ok; bool go; /* if you don't use the parameter, you can do like this to avoid the compiler warning about it */ (void)parameter; /* if you are using a global api pointer, don't forget to copy it! otherwise you will get lovely "I04: IllInstr" errors... :-) */ rb = api; /*Get the pattern handle*/ h1=rb->lcd_get_locked_pattern(); h2=rb->lcd_get_locked_pattern(); hcry=rb->lcd_get_locked_pattern(); hsmile=rb->lcd_get_locked_pattern(); rb->splash(HZ, "NIM V1.2"); rb->lcd_clear_display(); /* Main loop */ while (1) { /* Init */ x=21; v=1; y=1; end=false; min=0; /*Empty the event queue*/ rb->button_clear_queue(); /* Game loop */ while(end!=true) { do { ok=1; y=1; display_first_line(x); rb->snprintf(str,sizeof(str),"[%d..%d]?=%d",min,v,y); rb->lcd_puts(0,1,str); go=false; while (!go) { button = rb->button_get(true); switch ( button ) { case BUTTON_STOP|BUTTON_REL: go = true; nim_exit(NULL); return PLUGIN_OK; break; case BUTTON_PLAY|BUTTON_REL: go=true; break; case BUTTON_LEFT|BUTTON_REL: go=false; if (y>min) y--; break; case BUTTON_RIGHT|BUTTON_REL: go=false; if (ydefault_event_handler_ex(button, nim_exit, NULL) == SYS_USB_CONNECTED) return PLUGIN_USB_CONNECTED; break; } display_first_line(x); rb->snprintf(str,sizeof(str),"[%d..%d]?=%d",min,v,y); rb->lcd_puts(0,1,str); } if ( (y==0) && (x<21)) { impossible(); ok=false; } else { if (y!=0) /*If y=0 and x=21 jump to CPU code */ { if ((y>v) || (y>x)) { impossible(); ok=false; } if (y-x==0) win(); else { v=y*2; x-=y; } } } } while (ok==false); display_first_line(x); /*CPU*/ if (x==1) lose(); else if (x==2) win(); y=0; if (end==false) { for (z=v;z>=1;z--) { if (x-z==1) y=z; } if (y<=0) { for(z=v;z>=1;z--) { if(x-(z*3)==2) y=z; } if ((y==0) && (x>14)) y=v; if (y==0) y=1; } v=y*2; x-=y; rb->snprintf(str,sizeof(str),"I take=%d",y); rb->lcd_puts(0,1,str); rb->sleep(HZ); } if ((x==1)&&(!end)) win(); min=1; } } nim_exit(NULL); return PLUGIN_OK; } #endif
