Timing subsystem
TIMER_UNIQUE	Don't run if there is an identical unique timer active
TIMER_OVERRIDE	For unique timers: Replace the old timer rather then not start this one
TIMER_CLIENT_TIME	Timing should be based on how timing progresses on clients, not the server.
TIMER_STOPPABLE	Timer can be stopped using deltimer()
TIMER_NO_HASH_WAIT	Prevents distinguishing identical timers with the wait variable. To be used with TIMER_UNIQUE
TIMER_LOOP	Loops the timer repeatedly until qdeleted. In most cases you want a subsystem instead, so don't use this unless you have a good reason.
TIMER_DELETE_ME	Delete the timer on parent datum Destroy() and when deltimer'd
TIMER_ID_NULL	Empty ID define
INITIALIZATION_INSSATOMS	New should not call Initialize
INITIALIZATION_INNEW_MAPLOAD	New should call Initialize(TRUE)
INITIALIZATION_INNEW_REGULAR	New should call Initialize(FALSE)
INITIALIZE_HINT_NORMAL	Nothing happens
INITIALIZE_HINT_LATELOAD	call LateInitialize at the end of all atom Initialization
INITIALIZE_HINT_QDEL	Call qdel on the atom after initialization
INITIALIZE_IMMEDIATE	type and all subtypes should always immediately call Initialize in New()
SS initialization hints
SS_INIT_FAILURE	Negative values incidate a failure or warning of some kind, positive are good. 0 and 1 are unused so that TRUE and FALSE are guarenteed to be invalid values. Subsystem failed to initialize entirely. Print a warning, log, and disable firing.
SS_INIT_NONE	The default return value which must be overriden. Will succeed with a warning.
SS_INIT_SUCCESS	Subsystem initialized sucessfully.
SS_INIT_NO_NEED	If your system doesn't need to be initialized (by being disabled or something)
SS_INIT_NO_MESSAGE	Succesfully initialized, BUT do not announce it to players (generally to hide game mechanics it would otherwise spoil)
SS_INIT_TIMER_KEY	The timer key used to know how long subsystem initialization takes
Overlays subsystem
GAME_STATE_STARTUP	Game is loading
GAME_STATE_PREGAME	Game is loaded and in pregame lobby
GAME_STATE_SETTING_UP	Game is attempting to start the round
GAME_STATE_PLAYING	Game has round in progress
GAME_STATE_FINISHED	Game has round finished

Define Details

#define
GAME_STATE_FINISHED

Game has round finished

#define
GAME_STATE_PLAYING

Game has round in progress

#define
GAME_STATE_PREGAME

Game is loaded and in pregame lobby

#define
GAME_STATE_SETTING_UP

Game is attempting to start the round

#define
GAME_STATE_STARTUP

Game is loading

#define
INITIALIZATION_INNEW_MAPLOAD

New should call Initialize(TRUE)

#define
INITIALIZATION_INNEW_REGULAR

New should call Initialize(FALSE)

#define
INITIALIZATION_INSSATOMS

New should not call Initialize

#define
INITIALIZE_HINT_LATELOAD

call LateInitialize at the end of all atom Initialization

The item will be added to the late_loaders list, this is iterated over after initialization of subsystems is complete and calls LateInitalize on the atom see this file for the LateIntialize proc

#define
INITIALIZE_HINT_NORMAL

Nothing happens

#define
INITIALIZE_HINT_QDEL

Call qdel on the atom after initialization

#define
INITIALIZE_IMMEDIATE
(X)

type and all subtypes should always immediately call Initialize in New()

#define
SS_INIT_FAILURE

Negative values incidate a failure or warning of some kind, positive are good. 0 and 1 are unused so that TRUE and FALSE are guarenteed to be invalid values. Subsystem failed to initialize entirely. Print a warning, log, and disable firing.

#define
SS_INIT_NONE

The default return value which must be overriden. Will succeed with a warning.

#define
SS_INIT_NO_MESSAGE

Succesfully initialized, BUT do not announce it to players (generally to hide game mechanics it would otherwise spoil)

#define
SS_INIT_NO_NEED

If your system doesn't need to be initialized (by being disabled or something)

#define
SS_INIT_SUCCESS

Subsystem initialized sucessfully.

#define
SS_INIT_TIMER_KEY

The timer key used to know how long subsystem initialization takes

#define
TIMER_CLIENT_TIME

Timing should be based on how timing progresses on clients, not the server.

Tracking this is more expensive, should only be used in conjunction with things that have to progress client side, such as animate() or sound()

#define
TIMER_DELETE_ME

Delete the timer on parent datum Destroy() and when deltimer'd

#define
TIMER_ID_NULL

Empty ID define

#define
TIMER_LOOP

Loops the timer repeatedly until qdeleted. In most cases you want a subsystem instead, so don't use this unless you have a good reason.

#define
TIMER_NO_HASH_WAIT

Prevents distinguishing identical timers with the wait variable. To be used with TIMER_UNIQUE

#define
TIMER_OVERRIDE

For unique timers: Replace the old timer rather then not start this one

#define
TIMER_STOPPABLE

Timer can be stopped using deltimer()

#define
TIMER_UNIQUE

Don't run if there is an identical unique timer active

if the arguments to addtimer are the same as an existing timer, it doesn't create a new timer, and returns the id of the existing timer
