Detailed Description

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

◆ 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).

◆ 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.
