|
+## How it works
|
|
|
+The program makes the terminal use non-canonical input and output by using termios. Then it updates and prints a 2D character array containing the board borders, snake, and food. Before terminating, the program restores canonical mode.
|
|
|
+
|
|
|
+
|
|
|
+Each part of the snake is a node of a dynamically allocated linked list that contains:
|
|
|
+- The snake's x and y coordinates
|
|
|
+- The character that represents it on the board
|
|
|
+- The part's direction
|
|
|
+- A pointer to a order node (more on orders below)
|
|
|
+- A pointer to the next snake part node
|
|
|
+
|
|
|
+An order keeps information on when a snake part should change to what direction. An order is also a node in a dynamically allocated linked list that contains:
|
|
|
+- The direction that this order eventually tells the snake part to go to
|
|
|
+- The delay i.e. how many ticks until the snake part has to change direction.
|
|
|
+- A pointer to the next order
|
|
