Function Documentation

draw_map_mode()

void draw_map_mode	(	const map_tile_t *	arr,
		int	height,
		int	width,
		vector2d_t	anchor,
		vector2d_t	player_pos )

Draws the map mode UI based on the given parameters.

Parameters

arr	The map array to be drawn
height	The height of the map
width	The width of the map
anchor	The anchor position of the map mode, defined as the top left corner
player_pos	The position of the player

Note

This function checks makes different checks to ensure the given parameters are valid. The checks are done in the following order:

• check if the array is NULL
• check if the height and width are greater than 0
• check if the anchor position is greater or equal 0
• check if the player position is within the bounds of the map If any of the checks fail, an error message is logged and the function returns.

draw_player_info()

void draw_player_info	(	int	x,
		int	y,
		vector2d_t	player_pos )

Draws the player information for the map mode.

This function renders player-related information such as health, position, and available commands.

Parameters

x	The x position of the player info to be drawn
y	The y position of the player info to be drawn
player_pos	The current player position
