What changed in EDuke32, build by build

This fixes a problem where the texcache file could grow without limit if something managed to corrupt the texcache index.

Some TROR layers were blocking hitscan shots because of the low limit.

* clipmove() - No longer traverses sectors once a distance limit is exceeded, and at most traverses 64 TROR sectors at once. * hitscan() - TROR sectors added to clipsectlist after regular next sectors. Only adds TROR sectors in a single direction, and at most 64 at once. * A_RadiusDamage - only add TROR sectors if inside damage radius. Also increase MAXDAMAGESECTORS to 512, same as MAXCLIPSECTORS. Fixes glitches and error spam in maps that make heavy use of TROR.

The instruction pointer wasn't being updated properly.

This would previously attempt invalid array access with index -1.

If the sector contains a TROR bunch, then whenever clipupdatesector() would normally return 1, instead run updatesector() and return 0 instead. The old approach did not work out in all situations. In Fury, certain flying enemies could not pass some TROR layers properly, and in AMC, trying to submerge in TROR water had the player glitch out on the surface. This exact approach had previously been used in AMC without any major issues for 2 years, before the recent TROR changes.

The problem with the previous version was that it didn't take overlapping geometry into account. This should be a more conservative approach that doesn't affect non-TROR uses of the cansee() function.

Invalid sectnums could previously be added to the clipsectlist if a hitscan shot passed a tror layer.

Squishing is now prevented if SE7 is present (as previously intended), or when the actor is standing on submergible TROR water.

terminx/eduke32#283

This resolves a bug in Duke3D where the player couldn't move while shrunk if a TROR sector was present on the map. It also ensures that the original clipping is used if no TROR bunch is present inside the sector in question. This should reduce the amount of backwards-compatibility problems.

The changes are now more conservative and only affect sprites on TROR layers.

- Add TROR-awareness in similar fashion to clipmove() and hitscan() - Continue scanning walls to damage even if MAXDAMAGESECTORS is reached - Increase MAXDAMAGESECTORS from 128 to 256

This commit adds a failsafe which corrects the given origin and destination sectnums of the "cansee()" function, by checking if the corresponding (x,y,z) coordinates are actually contained within the given sectors. The problem with TROR in particular was that the calculation done to determine the point of intersection on the TROR layer requires the coordinates to be within the given sectnums. Else, cansee() would simply return 0, even if there was a clear line of sight. This should also implicitly fix any other cases where the coordinates of the cansee() call do not exactly match up with the given sectnums.

And fix problems introduced by 9070cd2bff6d4547f0765fc483ffd4f923e24383.

Also fixes sprite shadows being drawn floating above floor slopes.

The sprite is now properly copied for each sector it stretches across.

- Vertically attached sectors are now added to the clipsectorlist - Entirely remove the previous TROR hack from hitscan() - Instead, hitscan() now also uses clipsectorlist, and detects whether a TROR transition floor or ceiling was hit. If so, any subsequent wall hits in the same sector are skipped. This fixes the following: - Collision and hitscan checks where a sprite stretches vertically across more than 2 TROR layers. - Hitscan shots being unable to clear sloped TROR surfaces. - A potential out-of-bounds array access in hitscan()

Analogous to the previous commit, it also checks the sprites of the upper and lower TROR bunch of the sector. This handles the case where a sprite is intersecting layers, and fixes hitscan shots not hitting enemies properly in such cases.

This makes it so that the sprites of the ceiling and floor bunch sectors of the sector being checked are also iterated over. This handles the case where a sprite is intersecting TROR layers, and fixes projectiles not hitting enemies properly in such cases.

This caused two problems: - The change with AC_FZOFFSET caused BLOODPOOL to jitter in Duke3D - The change with water floors caused various actors to jitter in Fury More trouble than it's worth.

Previously, they would get stuck in a deactivated state while the player was still in range.

And apply some cleanup to the code in question.

This fixes a division by zero crash if zoom == 0.

Fixes

terminx/eduke32#272

Previously, this would be the default selection and say "CVAR"

Fixes

terminx/eduke32#273

These would default to 0 after loading the savegame.

This prevents a visual jitter effect from sprites that aren't moving, but use the "fall" command in a water sector (zombie actors, pickups, etc).

Same fix as applied for Mapster32 in c7aa59b001

Hitting CTRL+F in Mapster32's map load menu, then exiting it with ESC would result in the next menu opening at the filesystem's root path, and not in the previously open folder.
