snake death judgment, eating food, scoring

One, the death of the Snake judgment: To install the border, hit their own death

Definition: Issnakedie ()//Snake death judgment function, return type bool type

Ideas:

// the next of the Serpent's Head, is the square is death     if(0 = = strncmp (&g_strgameback[g_arrsnake[0] [0]][g_arrsnake[0 [1] + g_arrsnake[0[2""2) )    {        returnfalse;    }

Second, randomly produce food and eat things to become longer

1, (1) produce random coordinates for food

// Generate random coordinates int  = rand ()%1= rand ()%1;

(2) Draw food on the resulting position:

strncpy (&g_strgameback[g_nrow][g_ncol*2"★"2);

At this point, the call function results in the display of food, but there is no judgment as to whether new food should be produced, so food is randomly generated.

(3) Deciding whether to produce new food

BOOL true ; // decide whether to produce new food if (false = = G_bisprofood)    {return  ;}

The randomly generated food coordinates and the ergodic snake array are placed in a loop to realize that there is only one food before the snake eats the food.

2, the snake eats the matter to become longer

When the head coordinates are equal to the coordinates of the food, the snake body becomes longer. First define a snake body length: int g_nsnakelen = 2;

//The snake Head cursor is equal to the coordinatesif(G_nrow = = g_arrsnake[0][0] && g_nlie*2= = g_arrsnake[0][1]){    //Snakes grow Up    if(To_east = = g_arrsnake[g_nsnakelen][2]) {G_arrsnake[g_nsnakelen+1][0] = g_arrsnake[g_nsnakelen][0]; G_arrsnake[g_nsnakelen+1][1] = g_arrsnake[g_nsnakelen][0] -2; G_arrsnake[g_nsnakelen+1][2] = g_arrsnake[g_nsnakelen][0]; }    Else if(To_west = = g_arrsnake[g_nsnakelen][2]) {G_arrsnake[g_nsnakelen+1][0] = g_arrsnake[g_nsnakelen][0]; G_arrsnake[g_nsnakelen+1][1] = g_arrsnake[g_nsnakelen][0] +2; G_arrsnake[g_nsnakelen+1][2] = g_arrsnake[g_nsnakelen][0]; }    Else if(To_north = = g_arrsnake[g_nsnakelen][2]) {G_arrsnake[g_nsnakelen+1][0] = g_arrsnake[g_nsnakelen][0]; G_arrsnake[g_nsnakelen+1][1] = g_arrsnake[g_nsnakelen][0] +1; G_arrsnake[g_nsnakelen+1][2] = g_arrsnake[g_nsnakelen][0]; }    Else if(To_south = = g_arrsnake[g_nsnakelen][2]) {G_arrsnake[g_nsnakelen+1][0] = g_arrsnake[g_nsnakelen][0]; G_arrsnake[g_nsnakelen+1][1] = g_arrsnake[g_nsnakelen][0] -1; G_arrsnake[g_nsnakelen+1][2] = g_arrsnake[g_nsnakelen][0]; } G_nsnakelen++; G_bisprofood=true;}

When the scoring function is written, it needs to be called in the variable length function of the snake, and the score is increased as well.

Third, scoring

Set cursor Position: SetConsoleCursorPosition ();

 8; // Set cursor Position setconsolecursorposition (GetStdHandle (std_output_handle), RD);p rintf ("score is:   "  9;    SetConsoleCursorPosition (GetStdHandle (std_output_handle), RD);p rintf ("%d" , g_nscore*);

The process is over.
