Detailed Description

Macro Definition Documentation

#define PATHFIND_LIST_MAX 20

Maximum number of nodes in the pathfinding lists.

#define pathfind_test_dir	(	x,
		y,
		dir_move,
		state,
		t
	)	(TILEMAP_ERROR_BLOCKED != tilemap_collide( x, y, dir_move, t ) && (NULL == mobile_get_facing( x, y, dir_move, state )) ? 1 : MOBILE_ERROR_BLOCKED)

Check for blocking terrain or other MOBILE objects preventing movement in dir_move.

Parameters

mover	Locked MEMORY_PTR to MOBILE performing the movement.
dir_move	Cardinal Directions to attempt to move in.
state	Locked MEMORY_PTR for current DSEKAI_STATE.
force	0 if movement should not be attempted if input is blocked globally, or 1 if it should.
t	Locked MEMORY_PTR for DSEKAI_STATE::map_handle.

#define pathfind_trace_printf ( ... )

Alias for debug_printf() enabled when PATHFIND_TRACE is defined.

This was made its own alias since pathfinding can get rather chatty when it's enabled!
