Before implementing the 3D engine, we should implement a more straightforward 2D rendering of the player on the map. This will be reusable as a minimap later. The field of view of the player shall be rendered in this 2D representation.

In the first place, we will open, read and parse the .cub file. This file shall contain the following data :

• floor color
• ceiling color
• North wall texture
• South wall texture
• West wall texture
• East wall texture
• map :
  • wall positions
  • empty cell positions
  • void cell positions
  • player position
  • player direction

All the above shall be stored in the following data structures :

typedef struct s_player	t_player;

struct s_player
{
    size_t	pos[2];
    double	direction;
};

typedef struct s_image	t_image;

struct s_image
{
    void	*ptr;
    uint32_t	*addr;
    uint16_t	width;
    uint16_t	height;
    uint16_t	bpp;
    uint16_t	line_len;
    uint16_t	endian;
};

typedef struct s_map	t_map;

struct s_map
{
    t_image	wall_textures[4];
    uint32_t	floor_color;
    uint32_t	ceiling_color;
    char	**raw_map;
    
};

typedef struct t_game	t_game;

struct s_game
{
    t_player	player;
    t_map	map;
};
