What changed in EDuke32, build by build

Savegame version has been bumped due to the projectile changes. There is no way this commit doesn't cause at least one bug, so 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.

DONT_BUILD.

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

This fixes engine-side sprite animation in the following scenario: CON code wants to draw a scene from EVENT_DISPLAYREST, but since it covers the whole screen, disables the drawing of the 3D scene beforehand (RETURN set to 1 from EVENT_DISPLAYROOMS). DONT_BUILD.

This fixes the level 5 corruption encountered when issuing that iteration. (Because the last sprite would be changed from e.g. statnum MAXSTATUS to 0.) It is also mandatory anyhow since the last sprite may be contained in the map.

Also, note a place that is the real cause for "what makes the player slide off enemies", as far as I can see.

cutscene "somefile.anm" { delay 10 } // defines somefile.anm with a delay of 10 120Hz tics between frames. a more typical framerate method may come later, but this is how the originals worked. Once defined, they can be played through CON with the new playback command, also called "cutscene". It works like this: definequote 12345 somefile.anm define ANIM_SOMEFILE 12345 ... cutscene ANIM_SOMEFILE // halts game execution and immediately plays cutscene, resuming execution when finished ... Sounds can be played during animations (and tiles can be overlaid, etc) like this: onevent EVENT_CUTSCENE ifcutscene ANIM_SOMEFILE { ifvare RETURN 12 // frame 12 sound FLY_BY rotatesprite ... } endevent The value of the RETURN var at the end of EVENT_CUTSCENE determines the next frame to play. This can be used for looping, etc. Attempting to play animations backwards outright is not advised as animations only seek in one direction (so rewinding requires running it through from frame 0 again). This is will WIP and hasn't been heavily tested at all, so please try it out.

- 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.

This allows for CON screen display code to use menu animations. The following is an example of how to adapt screen features that should animate. before: onevent EVENT_DISPLAYMENUREST ifvare current_menu 0 // main menu { setvar x 1 setvar y 1 rotatesprite x y zoom ang tilenum shade pal orientation 0 0 xdim ydim } endevent after: state DisplayMenuCommon ifvare RETURN 0 // main menu { getuserdef[THISACTOR].m_origin_x x getuserdef[THISACTOR].m_origin_y y addvar x 65536 addvar y 65536 rotatesprite16 x y zoom ang tilenum shade pal orientation 0 0 xdim ydim } ends onevent EVENT_DISPLAYMENUREST state DisplayMenuCommon endevent onevent EVENT_DISPLAYINACTIVEMENUREST state DisplayMenuCommon endevent

In setview(), we now assert windowx2 < xdim. The only calling places where its non-violation is non-trivial to ascertain are (1) showview from CON and (2) draw-to-tile for look-sideways in game.c. AFAICS case 1 should be fine. Case 2 is adapted; see comments there.
