Defines
#define	CALC_XOFFSET(x, xsmall)   ( 8 * ( (xsmall) - xo_small + 2 + ((( (x) - xo ) << 1))) )
	Convert world X coordinate (level block coordinate) to view (world display buffer) coordinates.
#define	CALC_YOFFSET(y)   ( 16 + ((y) - yo) * 16 )
	Convert world Y coordinate (level block coordinate) to view (world display buffer) coordinates.
#define	WORLDX2VIEW(x)   ( -(8*xo_small) + ((x) - (16*xo)) + 16 )
	Convert world X coordinate (pixels) to view (world display buffer) coordinates. Theoretically this should probably eventually replace CALC_XOFFSET.
#define	WORLDY2VIEW(y)   ( ((y) - (16*yo)) + 16)
	Convert world Y coordinate (pixels) to view (world display buffer) coordinates. Theoretically this should probably eventually replace CALC_YOFFSET.
#define	THING_DIE   -1
	This crap should go. Fixme.
#define	THING_REMOVE   -2
	Remove, but not delete.
#define	REGISTER_THING(ClassName, nTypeID, pPerLevelInitProc)
	Macro that "thing"s can use (in the .cpp file) to register handlers in the thing factory. More...
Typedefs
typedef CThing* (*	THING_ALLOCATER )()
	The CThingFactory uses functions that look like this to allocate CThing's.
typedef void (*	THING_PERLEVELINIT )()
Enumerations
enum	EdjLayer {   LAYER_BOTTOM,   LAYER_2,   LAYER_MIDDLE,   LAYER_4,   LAYER_TOP }
	Used to indicate the order in which "things" get drawn. Things at higher layers get drawn over things at lower layers. More...
Functions
CThing*	CreateFloatingScore (int x, int y, int score)
	Create a CFloatingScore at (x,y) with score score.
CThing*	CreateExplosion (int nX, int nY)
	Create a CExplosion at (nX,nY) (pixel coordinates).
CThing*	CreateDust (int nX, int nY)
	Create a CDust effect at (nX, nY) (level coordinates).
Variables
CThingFactory	g_ThingFactory
	Single global "thing" factory.

Define Documentation

#define REGISTER_THING( ClassName, nTypeID, pPerLevelInitProc )

Value: CThing *ALLOCATE##ClassName() \ { \ return new ClassName; \ } \ static int UNIQUEID##ClassName = g_ThingFactory.Register(nTypeID, ALLOCATE##ClassName, pPerLevelInitProc); Macro that "thing"s can use (in the .cpp file) to register handlers in the thing factory.

Enumeration Type Documentation

enum EdjLayer

Used to indicate the order in which "things" get drawn. Things at higher layers get drawn over things at lower layers. Enumeration values: LAYER_BOTTOM   Layer 1; Absolute bottommost. Drawn first. LAYER_2   Layer 2. LAYER_MIDDLE   Layer 3; Hero gets drawn at this level. LAYER_4   Layer 4. LAYER_TOP   Layer 5; Absolute top-most, e.g. score floating letters.
