Cosa è cambiato in EDuke32, build per build

Similarly to how -5 and -7 and are accepted since r3859.

Background: AMC TC initializes per-player variables from this event.

DONT_BUILD.

EVENT_DISPLAYROOMSCAMERA functions exactly like EVENT_DISPLAYROOMS, including RETURN values, but for the ud.camerasprite >= 0 case. EVENT_DISPLAYSTART is executed immediately after the screen background is cleared and drawn. Ensure its RETURN value is zero, because it is currently not being used. WARNING: Consult the devs before using EVENT_DISPLAYSTART. Its position in the display code sequence is not finalized.

From this event, if "getactor[THISACTOR].htg_t 0" is zero, then the camera is functional. Nonzero values indicate the camera has been destroyed, which is only possible when the CAMERASDESTRUCTABLE parameter of gamestartup has been enabled.

enum { EF_HIDEFROMSP = 1<<0, EF_HIDEFROMMP = 1<<1, };

- Add declarations of C functions to defs.ilua, names to dynsymlist, fix typo in con_lang.lua, ffi.string() calls in control.lua - Assert that G_LastMapInfoIndex() is always called with ud.last_level >= 1. (A stricter requirement than necessary to prevent follow-up oob accesses, but logically the most meaningful.) - In G_PrintParTime() and G_PrintDesignerTime(), return "<invalid>" if the above does not hold. This can happen from EVENT_NEWGAME, for example. Add a test to lunatic/test/qgetsysstr.con. DONT_BUILD.

// Example: Switch between tracks like radio stations. getmusicposition temp starttrackvar next_music_track setmusicposition temp Only implemented for Ogg Vorbis, FLAC, and XA. Consult the devs before using these commands.

Previously, the C function clipmove() returned negative values when hit a wall (32768+wallnum) or sprite (49152+spritenum) because internally, these values were encoded into a *signed* 16-bit integer. This made no difference to C code using it, since it always proceeded by bit checks, but was inconsistent with documentation on CON 'clipmove' on the wiki. The following commands are affected too, since they use the value returned by clipmove(): 'clipmovenoslide', 'movesprite'. Also, the value of actor[].movflag ('htmovflag' from CON). Also, fix 'clipmove*' in LunaCON and add lunatic/test/checknearwall.con as an example of how to implement a being-close-to-a-wall checker as requested in http://forums.duke4.net/topic/7869-determining-closeness-to-a-wall/
