Detailed Description

Initializes and renders the map drawing area. Handles map drawing area events, notably the "click to look at" mouse event.

Definition in file map.c.

Function Documentation

◆ coord_to_tile()

static void coord_to_tile	(	int	x,
		int	y,
		int *	dx,
		int *	dy
	)

static

Given x, y coordinates on the map drawing area, determine the tile that the coordinates are on with respect to the player.

Clicking on the tile with the player returns (0, 0).

Definition at line 589 of file map.c.

◆ display_map_doneupdate()

void display_map_doneupdate	(	int	redraw,
		int	notice
	)

This is called after the map has been all digested.

this should perhaps be removed, and left to being done from from the main event loop.

Parameters

redraw	If set, force redraw of all tiles.
notice	If set, another call will follow soon.

static

Create light map nx wide, ny tall. Add a border 1px around to get rid of edge effects.

static

Draw anything in adjacent squares that could smooth on given square.

Parameters

mx
my	Square to smooth on. You should not call this function to smooth on a 'completely black' square.
layer	Layer to examine (we smooth only one layer at a time)
picx
picy	Place on the map_drawing_area->window to draw
