Detailed Description

Function Documentation

int player_collided_with_borders ( )

Depending on the game mode, the player may be able to hit borders or not.

If it is possible, we call player_hit_borders().

int player_hit_borders ( )

Checks collision between the snake and the walls.

int player_hit_fruit ( )

Checks if the snake has eaten the fruit.

void player_increase_size ( int size )

Increases the snake size.

Here we have the core function of this file. Each time the snake increases its size, we expand the array that represents its body.

Note:: This is the main function of this file, because it shows how i've implemented the snake. In the future, we could use a linked list instead of an array.

void player_update ( )

Updates the player position, one piece at a time.

Start by moving the snake pieces one at a time from the last to the first, and then moves the head according to its direction.
