Made the bottom of the viewborder visible when the status bar doesn't cover the full width of the screen and no border would normally be visible.
Added SetAmmoCapacity (str typename, int maxamount) and GetAmmoCapacity (str typename) ACS commands. Also added the ACS log command. It is exactly like printbold, except it prints directly to the console instead of the middle of the screen. BTW, ACS has static local variables ala C now. They are exactly the same as map variables, except they can only be used in the script or function that defines them.
Fixed some fullscreen pages to work properly with non-4:3 aspect displays.
Fixed DCanvas::DrawTexture() so that all virtual sizes (not just 320x200wide) work with non-4:3 aspect screens. (So long as the virtual size is 4:3.)

December 22, 2004

Fixed: The backpack was not added to the player's inventory, although there was code present to handle removing it from the inventory.
Loading a BEHAVIOR without any scripts but with other content crashed.
More revelations with the sprite splitting experiment: Drawsegs are not always created when you might think they are. Probably the biggest problem is when you look at a line straight-on, so you see the sectors on each side of it but not the line itself. I conceded defeat and stuck an #if 0 around the related code. If I or someone else want to revisit it later, it's still there but inactive. I don't think it's worth the effort to make it work properly. A z-buffer would be much easier, more reliable, and possibly even quicker when there are a lot of two-sided lines in view. So the solution seems obvious: Use hardware acceleration and let it worry about sprite clipping. Or stick with the way things are and ignore it. :-) (Community Chest 2, MAP15, building number 4 makes a great test-case for this, BTW.)

December 21, 2004

Messed around with splitting sprites along drawsegs some more. This is far from being as straight forward as I had thought. One unexpected problem I realized: Most (if not all) of the sprites that stand on the ground are actually sunk into the ground, but splitting sprites is not a win unless you clip them to the floor and ceiling. So I tried bumping the sprites up so that they are aligned with the bottoms of their actor so I could clip them to the floor. Now it looks much better. When it works. Unfortunately, there are lots of cases that still don't work properly.

December 20, 2004

Added some code to split sprites along drawsegs.
Changed the sprite-in-front of drawseg calculations. Now it compares inverse Z values in screen space.
Fixed: The MinotaurFriend targetted friendlies other than itself.
Fixed: An actor's floorpic was not serialized by name.
Fixed: Each piece of Hexen armor only gave you one AC.
Fixed: Morphing a monster didn't copy the original monster's friendliness and TID hating to the morphed version.

December 18, 2004

Fixed: Slideshows in Strife are supposed to change the music to D_SLIDE.
Fixed: Merchants played their greeting animation in place of their "yes" animation. (Or rather, the greeting was played immediately after starting the "yes" one, so you only saw the greeting.)
Fixed: The Strife health bar texture assumed that the vial level would always be non-negative. It can go negative if the player dies then cheats to give themself health, but not enough for their real health to go positive.
Fixed: Creating a fade-in-out hudmessage with a fadetime of 0 crashed, because it assumed the fade-in time would always be positive.
Fixed: Instead of calling G_StartTravel(), idclev should set the player's health to 0, so the player will do a complete spawn on the new level.
Fixed: DrBNumberOuter(Font) and DrINumberOuter drew the shadow from one digit on top of the next digit.
Fixed: The Doom HUD drew the selected inventory item on top of the secondary ammo if both were present.
Moved the DrawPowerups() call out of FBaseStatusBar::Draw() and into DrawTopStuff(), so the Doom HUD key display won't cover them up
Fixed: If you started flying and then pressed the land key, you wouldn't be able to fly again until the Wings of Wrath wore off. This was done by changing several checks for a player with MF2_FLY into checks for a player with MF_NOGRAVITY. MF2_FLY just indicates that the player is using the Wings; for the player to fly, MF_NOGRAVITY must also be set. If MF_NOGRAVITY is not set, but MF2_FLY is, then the pressing +moveup/down reactivates fly mode.
Changed the receipt of BasicArmorPickup so that the SaveAmount is multiplied by the given amount (via the give cheat or ACS giveinventory) in order to make it compatible again with earlier versions of ZDoom.
Fixed: Picking up an armor bonus after using up your armor left you with useless armor until you picked up a full-fledged armor item.
Fixed: Even though voodoo dolls couldn't pick up items, they could still touch them without pretending to be a real player and mess things up in the player's inventory.
Fixed: Strife's alien spectres did not execute specials attached to them upon death, because they have MF_SPECIAL set.
Changed the inventory left/light gems (that indicate if you have more items in that direction) to blink with gametic instead of level.time, so now they can blink while the game is paused.
Fixed: You could use items while the game was paused.
I just noticed the fighter's fist doesn't meet the edge of the screen when you swing it. What's a good, clean way to handle this situation?
Brought over the startup log viewer I had added for my Duke port. Unlike my Duke port, however, this window is normally hidden and only shows itself when a fatal error occurs. Now if something goes wrong during the startup sequence, you can review the console log to try and figure out why. I tried making it show up at startup as a sort of revival of the way the startup process worked once upon a time in DOS land, but too much of the code now requires the video to be one of the first things initialized and it just isn't practical to rearrange things to make it init later.

December 16, 2004

New: ZDoom.wad is now managed along with the source code.

December 15, 2004

Added support for letterboxing, so people without widescreen displays can still use widescreen modes without running in a window. Note that if the video card enumerates any widescreen displays, then the game will assume they are displayed as widescreen, even if they really aren't. Letterbox modes are automatically generated from the existing 4:3 modes, but if an existing resolution already has the same size, then that resolution won't be available in letterbox form. The video modes menu displays LB next to any modes that are letterboxed, so you can tell them apart without trying each one.

Corrected widescreen displays for non-90 degree FOVs.

December 14, 2004

Added support for 16:10 and (if vid_tft is true) 5:4 displays. Also rearranged the video modes menu, removing the depth choice and replacing it with an aspect ratio choice.

December 13, 2004

Rewrote the interpolators to use a hash table instead of a linear array, for improved insertion and deletion performance.
Added interpolation for scrolling floors, ceilings, and walls. Floors especially need it, because the lack of interpolation really sticks out when you're being carried along by a floor that only moves at 35 FPS.
Resolutions are now sorted, and you can pick widescreen resolutions if you play in a window even if your don't have any fullscreen widescreen modes. (Yep, 16:9 modes are now supported.)

December 11, 2004

Decided it's time to bring the goodness of Polymost to ZDoom. Stage 1 complete: Convert the clipper to a stand-alone C++ class. Stage 2 to be completed some time in the indeterminate future. There's really other things that I should be doing right now, ne?

December 9, 2004

Fixed: APlayerPawn::BestWeapon() did not know about the Tome of Power, so when you ran out of sufficient ammo for your tome'd weapon, it could select the untome'd version of that weapon, which would turn into the tome'd version when it was raised, so you would be stuck in a cycle until the tome ran out or you picked a different weapon manually.
Fixed AMinotaur::Die() should have used a thinker iterator instead of an actor iterator to look for minotaurs that are still alive.
Added Graf's deltaviewheight fix for climbing stairs made of actors.
Fixed up the pickup ammo amount for the BFG. (Was 100, should be 40.)
Merged in Jim's ACS character array printing support.

December 6, 2004

Fixed: Fog boundaries flashed with gunfire. That's wrong because foggy sectors don't flash.
Fixed: Masked textures in a skybox would determine their height from the viewz used for the last skybox drawn instead of the viewz for the skybox they belong to.
Fixed: "*fistgrunt" was undefined, so A_FPunchAttack() was unable to play it.
Fixed: Hexen players did not play their burn death sounds. Neither did the cleric boss.
Fixed: Thingcount should not count items in somebody's inventory.
Fixed: AInventory::BecomeItem() did not remove the item's TID, so it could still be manipulated by scripts even after being picked up.
Fixed: CheckBossDeath() should consider frozen corpses as not dead, because A_BossDeath() is not called until the corpse shatters.
Changed APlayerPawn::Die() to use P_DropItem() to spawn a new weapon when weapondrop is turned on instead of dropping the player's actual weapon.
Fixed: P_DropItem() needs to clear the MF_NOGRAVITY flag because some Hexen items have it set.
Fixed: ArtiTeleport::Use() called P_UndoPlayerMorph with its player instead of its owner's player.

December 4, 2004

Updated the libraries and moved them out of src and into the base directory. Now zlib is at version 1.2.2, libFLAC is version 1.1.1, and src contains only the ZDoom-specific files.
Updated to zlib 1.2.2.

December 3, 2004

Fixed: 256 entries per column is not enough for dc_tspans. Each column should have MAXHEIGHT entries available, because a column that alternates drawn/not- drawn pixels each row will need one entry per row.

December 2, 2004

Fixed playback of SPCs when spc_8bit is true. SNESAPU renders them unsigned, but we need them to be signed. Also fixed: Altering spc_stereo and spc_8bit while a SPC was playing could crash.
Added new stuff to the alternate sound renderer: MMX CopyAndClip routine, interpolated mixers, FLAC sample loading, streams, and slightly tighter inner. So now it's a bit more of a realistic alternative to FMOD. All it really lacks is MP3, Vorbis, and MOD support. The snd_interpolate cvar can even select between linear (1) and quadratic (2) interpolation, so it can sound better than FMOD, which only does linear interpolation. I'd like to compare the performance of the new code with FMOD, but unfortunately, I can't seem to figure out a good way to calculate % CPU used by the mixer. My attempts lead to numbers that fluctuate quite a lot for relative constant environments. At least it ought to be attractive to the Linux folks if it gets modified to support SDL as well as DirectSound, even if I have no idea how well it performs.

December 1, 2004

Reorganized the sound interface code to make it easier to target multiple sound renderers.

November 29, 2004

Added the CTRL-X keypress for clearing the current console command line.
Changed tab completion to be more Bash-like: When there is more than one possible completion, and they all have a common prefix longer than what has been typed so far, the full prefix will be filled in for you. (e.g. Typing "sn[TAB]" will append "d_" for you because every command that starts with "sn" also starts with "snd_".) Note that this only works if you have the completion list turned on (con_notablist is false).
Fixed: Only the first berserk pack you picked up would give you health.
Fixed: Soul sphere played the wrong pickup sound.

November 25, 2004

Added render-to-texture support to the engine. Using it requires you do two things:
1. Define a texture that can be drawn into. You do this with a line in ANIMDEFS:
  cameratexture <texture name> <width> <height> [fit <width> <height>]
  e.g.
  
  cameratexture CAMTEX1 64 64
  
  Creates a texture called CAMTEX1.
  
  cameratexture CAMTEX2 100 50 fit 80 50
  Creates a texture called CAMTEX2. Its actual dimensions are 100x50,
  but it will be scaled to fit into an area 80x50 units large.
  
  cameratexture STARTAN2 64 64
  
  Replaces the existing texture STARTAN2 with a new one that can be rendered into. Since no fit size was provided, this new texture will be sized to occupy the same space as the old STARTAN2 texture, which is 128x128.
  
  cameratexture STARTAN2 64 64 fit 64 64
  
  Replaces the existing texture STARTAN2, but leaves the texture unscaled by specifying a fit size that matches the real size.
  
  Square textures use less memory than non-square textures. However, if you want to use a camera that can see the texture it renders into, you should use a non-square texture.
2. Use ACS to identify which camera renders to the texture: SetCameraToTexture (<camera tid>, <texture name>, <FOV>);
  e.g.
  SetCameraToTexture (100, "CAMTEX1", 90);

November 24, 2004

Expanded the definition of local for such things as "localambientsound" so that players will still hear the sound if they are looking through a camera.
Added the summonfriend command.
Made P_RandomChaseDir() truely random. The only real randomness it had before was in deciding whether monsters preferred to go east or southeast.

November 20, 2004

Fixed: AInventory::BecomeItem() must remove the actor from all the touching sector lists. Otherwise, you can get crashes if a floor or ceiling in a sector touching the item moves later.
Fixed: Patrols only went to the first goal and then got stuck.
Fixed: Recurssion when an unloading script tries to change to a different map. The map change is already under way, so the script cannot start another map change.
Moved BasicArmor's PostBeginPlay icon fixing into Tick, so it can cope with the "give armor" cheat removing the icon when the player already has armor.
