This article introduces the knowledge of "code sharing of gluttonous snake games implemented in C language". In the operation of actual cases, many people will encounter such a dilemma. Next, let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Scheme design

First, initialize the background, use the global two-dimensional array map [] [] to represent the entity content, and set the boundary condition, that is, the array boundary is set to WALL:

/ / initialize the wall for (int I = 0; I

< ROW; i++) { map[i][0] = map[i][COL - 1] =WALL; } for (int j = 0; j < COL; j++) { map[0][j] = map[ROW - 1][j] =WALL; } 游戏启动时设置蛇在map数组中的位置，用全局一维数组snake保存蛇位置信息。 食物设置 在map数组内找到一格空地放置食物。为了防止每次产生的随机数相同，初始化时种子设置为time，同时这里注意出现死循环。 voidcreate_food(){ int row, col; int cnt = 100; do { cnt--; row = rand() % (ROW - 1) + 1; col = rand() % (COL - 1) + 1; } while (map[row][col] != SPACE&& cnt); map[row][col] = FOOD;} 蛇移动方案 1、空地 移动方向前方为空地，删除蛇尾，空地置为蛇头： case SPACE: map[snake[SnakeSize -1].X][snake[SnakeSize - 1].Y] = SPACE; //原蛇尾位置置空 for (int i = SnakeSize - 1; i >

0; iWhat -) / / move one bit from snake tail to snake head {snake [I] = snake [I-1];} map [snake [0] .X] [snake [0] .Y] = SNAKE; / / the original snake head position is set to snake body snake [0] = next / / the next location is set to snakehead map [snake [0] .X] [snake [0] .Y] = HEAD; / / Update map break

2. Food

Update the score and snake size information, set the next location to snakehead, and generate new food.

Case FOOD: for (int I = SnakeSize; I > 0 SNAKE) / / move one bit from snake tail to snake head {snake [I] = snake [I-1];} map [snake [0] .X] [snake [0] .Y] = SNAKE / / Snakehead snake [0] = next; / / assign the next position to the snakehead score++; / / score plus one SnakeSize++ / / Snake size plus one map [snake [0] .X] [snake [0] .Y] = HEAD; / / Update map create_food (); break

3. Wall / Snakebody / Snakehead

The game ends when the next position is not SPACE.

Direction control

Read the keyboard interrupt and ignore case. One thing to note here is that when the snake moves to the right, it is invalid to choose to move to the left, that is, to ignore the reverse motion command.

Mainstream programs use while (1) endless loops:

While (1) {T2 = GetTickCount (); DrawMap (); if (kbhit ()) / / get the keystroke event {ChangeDir (); / / set the direction of motion according to the input character creep (); / / make a decision based on the next position

T2 = GetTickCount (); T1 = T2;}

If (T2-T1 > time_interval) / / this is to ensure that even if the user does not operate, the snake can still move forward a position {creep (); T1 = T2;}} "code sharing of the gluttonous snake game implemented in C language".
