Data Structures
struct	TITLE_STATE
	State for ::ENGINE_TYPE_NONE. A simple title screen engine. More...
struct	TOPDOWN_STATE
	State for ::ENGINE_TYPE_TOPDOWN. Displays a top-down 2-dimensional view of the world. More...
struct	POV_STATE
	State for ::ENGINE_TYPE_POV. Displays a first-person 3D view of the world using raycasting. More...
struct	EDITOR_STATE
struct	DSEKAI_STATE
	General/shared state of the running engine in memory. More...

Macros
#define	MINIMAP_X   (SCREEN_W - TILEMAP_TW - 10)
#define	MINIMAP_Y   (10)
#define	DSEKAI_TRANSITION_MASK_FRAME   0x0f
	Mask indicating bits of DSEKAI_STATE::transition that denote the current transition's frame.
#define	DSEKAI_TRANSITION_MASK_TYPE   0x70
	Mask indicating bits of DSEKAI_STATE::transition that denote the current transition's type.
#define	DSEKAI_TRANSITION_DIR_OPEN   0x80
	If this bit is on, then the currently playing transition should be opening. If it's off, the transition is closing.

Typedefs
typedef void(*	title_option_cb) (struct DSEKAI_STATE *state)
typedef int16_t(*	ENGINES_SETUP) (struct DSEKAI_STATE *state)
	Sets up the current engine (allocates specific state, etc).
typedef int16_t(*	ENGINES_INPUT) (INPUT_VAL in_char, int16_t click_x, int16_t click_y, struct DSEKAI_STATE *state)
	Handles polled input according to the rules of the current engine.
typedef void(*	ENGINES_ANIMATE) (struct DSEKAI_STATE *state)
	Cycles animations and executes scripts relevant to the current engine.
typedef void(*	ENGINES_DRAW) (struct DSEKAI_STATE *state)
	Draws the engine sceen on-screen according to current state.

Functions
void	engines_draw_loading_screen ()
	Draw a simple loading screen.
int16_t	engines_warp_loop (MEMORY_HANDLE state_handle)
	Handle transition to a new TILEMAP.
void	engines_animate_mobiles (struct DSEKAI_STATE *state)
	Do generic mobile animation and execute their scripts.
int16_t	engines_loop_iter (MEMORY_HANDLE state_handle)
	Central loop iteration handler. Calls engine-specific callbacks.
int8_t	engines_input_movement (struct MOBILE *mover, int8_t dir_move, struct DSEKAI_STATE *state)
	Handle generic player movement commmand.
