Lunatic: update documentation a bit.
- add gv.GET, gv.WEAPON, gv.RETURN - specify that sprite[].x/y/z and wall[].x/y are 32-bit ints - add an example for con.longjmp() - add an appendix listing the RETURN usage of various events git-svn-id: https://svn.eduke32.com/eduke32@4032 1a8010ca-5511-0410-912e-c29ae57300e0

Game event `RETURN` usage
|
||||
-------------------------
|
||||
|
||||
The following list notes how the special <<gv_RETURN,`gv.RETURN`>> variable
|
||||
(known simply as `RETURN` from CON) is treated for the various events. The game
|
||||
may either pass some value to a particular event as additional information, or
|
||||
it can examine `RETURN` after the event has finished, invoking some behavior
|
||||
conditional on its value. If an event is not listed here, its usage of `RETURN`
|
||||
is unspecified.
|
||||
|
||||
[float]
|
||||
Receives zero, checks for non-zero
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
These events get passed a value of 0 for `RETURN`, and after finishing, check
|
||||
it for being non-zero, in which case some hard-coded behavior is suppressed:
|
||||
|
||||
`AIMDOWN`, `AIMUP`, `CROUCH`, `DISPLAYSBAR`, `DISPLAYWEAPON`, `DOFIRE`,
|
||||
`DRAWWEAPON`, `FIRE`, `HOLODUKEOFF`, `HOLODUKEON`, `HOLSTER`, `INCURDAMAGE`,
|
||||
`INVENTORY`, `JUMP`, `LOOKDOWN`, `LOOKLEFT`, `LOOKRIGHT`, `LOOKUP`,
|
||||
`QUICKKICK`, `RETURNTOCENTER`, `SOARDOWN`, `SOARUP`, `SWIMDOWN`, `SWIMUP`,
|
||||
`TURNAROUND`, `USEJETPACK`, `USEMEDKIT`, `USENIGHTVISION`, `USESTEROIDS`.
|
||||
|
||||
`KILLIT` (deprecated from Lua)::
|
||||
If non-zero, the pending sprite deletion is aborted.
|
||||
|
||||
`DISPLAYROOMS`::
|
||||
Don't draw scene if `RETURN` is 1. Values other than 0 and 1 are
|
||||
reserved.
|
||||
|
||||
`PRESSEDFIRE`, `USE`::
|
||||
If non-zero, the ``fire'' or ``use'' shared key bits are cleared
|
||||
(respectively).
|
||||
|
||||
[float]
|
||||
Game considers post-event `RETURN` an index
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
For some events, the game examines `RETURN` after they have finished, and
|
||||
potentially uses its value as some kind of index.
|
||||
|
||||
`CHANGEMENU` (deprecated from Lua)::
|
||||
Receives and examines `RETURN` as a menu index to change to.
|
||||
|
||||
`DISPLAYCROSSHAIR`::
|
||||
Receives 0. If the post-event `RETURN` equals 1, no crosshair is drawn. If
|
||||
it is greater than one, `RETURN` is the tile index of the crosshair to be
|
||||
displayed. The value 0 makes it draw using the `CROSSHAIR` tile.
|
||||
|
||||
`GETLOADTILE`::
|
||||
Receives and examines `RETURN` as a background tile for the loading screen.
|
||||
A negative value suppresses drawing it and running the subsequent
|
||||
`EVENT_DISPLAYLOADINGSCREEN` entirely.
|
||||
|
||||
`GETMENUTILE`::
|
||||
Receives and examines `RETURN` as a background tile for the menu.
|
||||
|
||||
`SOUND`::
|
||||
Receives and examines `RETURN` as an index of a sound to start playing.
|
||||
|
||||
[float]
|
||||
Cheat events
|
||||
~~~~~~~~~~~~
|
||||
The cheat events receive a hard-coded, item-dependent target amount in
|
||||
`RETURN`. It can be overridden to a different value to make the respective
|
||||
cheat give a different ``full'' amount. A negative value is ignored.
