What changed in EDuke32, build by build

When calculating which rotation to use for CON action viewtype 7, offset the frame intervals by 15 degrees instead of 22.5, clearly a copypaste error from viewtypes 5 or 8. Now these are properly centered.

Add wall.blend to structure access.

Add EVENT_PRELOADGAME and EVENT_POSTLOADGAME.

Add drawline256 and drawlinergb commands that call the internal functions used for the automap lines.

Add getclosestcol command, which finds the closest palette index given

Add EVENT_DISPLAYOVERHEADMAPTEXT.

Potential CON performance improvements

Can Duke3D CON version compatibility messages in standalone builds

Gamevar cleanup

Use macros for special gamevar access range checking

Change hard-coded subway effect damage to generic explosive damage that can be handled by CON. Fixes subway kills not counting toward the dead monster count and allows CON scripts to handle subway damage however they like.

Move Mapster32 autoexec to before the map specified on the command line is loaded, to allow EVENT_PRELOADMAP and EVENT_LOADMAP to work when loading a map from the command line. This makes the console output of autoexec a little worse but the OSD will be fixed at a later time.

Handle the save and savenn commands after the full tic is processed, instead of in the middle of it during execution. DONT_BUILD.

Add undefinegamefunc.

Factor out code for launching EVENT_GAME and EVENT_PREGAME.

weapons.con.sample: Use full precision when applying weapon scaling.

weapons.con.sample: Add internal temp variables for rotatesprite parameters that the subroutines need to modify. This fixes weapon scaling.

weapons.con.sample: Rename hud_G_Draw_temp* to hud_int_temp*.

weapons.con.sample: Only setvar RETURN -1 for values of drawweapon that we actually handle. (Currently all of them, but this is more future-proof.)

weapons.con.sample: No need to andvar before getting a sine value. The source does that for us.

Remove bounds check on rotatesprite coordinates.

C-CON and M32script: Only accept hex literals beginning with '0' and not any other digit.

Implement "divscale" and "scalevar" (scale()) in C-CON and "scalevar" in M32script.

Fix addlogvar command, broken in r5835.

Allow gamestartup to read in one additional parameter (MAXFLAMETHROWERAMMO). Do nothing with it yet.

Implement "ifplaybackon" conditional, used by World Tour to determine if the replay feature is enabled. In our case, it is always false.

Minor changes to gamevar error handling

Misc cleanup. Removed ability to use .CON files found in the .GRP when the .CON files found in the directory can't be compiled.

Fix detection of menu sounds in EVENT_SOUND

Support saving specified CON arrays in map states

Add an optional sixth parameter, a flags bitfield, to action definitions. Bump BYTEVERSION.

Remove some unused gamevars pertaining to the original multiplayer code. DONT_BUILD.

Fix EVENT_DISPLAYROOMS and EVENT_DISPLAYROOMSCAMERA RETURN values

Fix problem with C-CON sector and wall structure access. Oops.

CON compilation and debug message fuckery affecting virtually nobody

Clean up a couple instances of direct usage of a magic number in the CON compiler. DONT_BUILD.

Make the bitptr stuff in the CON compiler more readable.
