What changed in EDuke32, build by build

This properly fixes the unwanted vertical lines.

Of course, it's just for the heck of it, since this setting is not saved into MAP files. I kinda like the cylindrical projection...

This has been there since searchbottomwall introduction in r1466.

Previously, it was possible to leave a sector with less than three walls if a point got deleted transitively by a TROR link. Now, a proper check is done for all deletion candidates and a message stating which wall and sector is problematic is printed. Thanks for Diaz for pointing out the brokenness.

- strip 'inline' from animateoffs() definition, remove declaration in build.h - one min/max -> clamp - one malloc/strlen/strcpy -> strdup

If one next instruction happened to be interpreted, madness would ensue, because the pointer wouldn't be aligned on the "opcode" part anymore. Also, with "seti", set current sprite index only after a successful validation.

This get into the writable variable the "linking type" of the sprite with index <spritenum>. The result is a bit field of ORed values: 1: lotag has linking semantics 2: hitag 4: extra, 8: xvel, 16: yvel, 32: zvel, 64: owner (custom only) Custom setting about which sprites have what kind of linking can be programmed via EVENT_LINKTAGS: it receives a sprite index as the 'current sprite' and is supposed to return the bit field in RETURN. An example which lists sprites and their linking hi- and lotags is provided in the state 'listusedtags' in a.m32.

Allow all drivers for now; if anything, we should start maintaining a blacklist now that most Intel chips have decent enough support to be able to run stuff satisfactorily.

This requires one tweak in drawrooms' umost/dmost setup to prevent oob access. Specifically, a coordinate difference of 0 is allowed. In the classic renderer, this would mean a one-pixel (real screen coords) height or width. In Polymost, it would currently mean a one-pixel height and zero-pixel width, but this might be subject to change.

The showview command transforms the 320-based screen bound coordinates to the real screen bounds like xreal = (x*xdim)/320, which shows a bias towards zero: for example, for a 1680 screen width, the maximum permissible value 319 is mapped to round_to_zero((319*1680)/320) == 1674. (The rounding is implicit in the integer division). This makes it impossible for a view to cover the whole screen with any other resolution than 320x200. The new command transforms the bounds like xreal = (x*(xdim-1))/319, which would map 319 to 1679 in the preceding example.

(That is, the base shade table.) Before, we allocated each palookup buffer. For a vanilla setup, this means that we're now saving 224*32*256 ~= 1.8 megs, which might be interesting for low-memory gadgets.

First, it's unlikely in our day and age. Second, they're always free'd at the end, so allocache'ing them is incorrect.

Also, - use this in game.c and astub.c palookup loading code - when makepalookup() is passed a 0 palnum, return early. This means that 'fogpal' will silently fail when attempting to change pal 0. - in 'makepalookup' DEF command, error out if passed a pal of 0.

The syntax is as follows: makepalookup { <token-list...> } where valid tokens are * pal <palnum>: the palette number, 1 .. 250 * red <num>, green, blue (or r, g, b): the fog color components on a 0 to 63 scale. Components that are not present are assumed to be 0. * remappal <palnum>: the palette number to take the index remapping from, i.e. 21 for blue -> red. When absent, defaults to 0. * remapself: when present, specifies that the remappal is the same as the 'pal'. This is to prevent textual redundancy when overwriting existing palookups. Examples (best tested with tile #251): 1) makepalookup { pal 200 red 30 remappal 23 } This creates palookup 200 with a fog of (30,0,0) and a blue-to-yellow remapping (assuming it has not been changed before) 2) makepalookup { pal 21 red 30 remapself } This 'fogifies' palookup 21 with a red fog. 3) makepalookup { pal 21 red 30 } This overwrites palookup 21 with a red fog, but clears the blue-to-red remapping. The fog aspect of this command affects the GL modes just like 'fogpal', but the remapping has no effect for hightiles. - Also, silently clamp 'fogpal' r,g,b values to the range 0 .. 63.

Instead of drawing the rooms and masks with the classic renderer once. The captured scene is transformed to use the base palette, so that the screenshot will also show up in classic. No aspect correction is done.
