To allow processing the hit through an arbitrary portal without reference to the portal group table, P_AimLineAttack and P_LineAttack need to pass some more info than just the linetarget.
We need the relative positions of shooter and target within the visual reference of the other to calculate proper angles and we need to know if such a portal was crossed at all, because a few things, e.g. seeker missiles won't work with them.
- fixed setup of target acquisition for the Mage Staff.
The pre-acquired seeker target was never passed to the spawned projectiles.
- converted the P_TranslatePortal* functions to use floating point trigonometry. The combination of R_PointToAngle and finesine even created discrepancies with perfectly parallel portals which is just not acceptable.
- added a function to FPathTraverse to relocate the trace and restart from the new position.
- made P_UseLines portal aware. Traversal through line portals is complete (all types, even teleporters), whether sector portals need better treatment remains to be seen - at the moment it only checks the range at the player's vertical center.
It can easily happen that the lower sector has no lines below the checked area, in which case it would not set the dropoffz correctly. To prevent this, P_LineOpening must, when it checks the opening over a sector portal, actually calculate the dropoff to the lower portal itself by calling sector_t::NextLowestPointAt. It also means that FindRefPoint must calculate a proper reference point when one side of the line to be checked is part of a floor portal.
This includes:
* allow one sided portal linedefs to be crossable when part of a polyobject. Due to the limitations, two-sided linedefs won't work here. For general use this is still not allowed because making them passable would require some crippling fudging.
* delay portal finalization until after polyobjects have been spawned.
* the camera interpolation also needs to handle angle differences.
The code is still not 100% complete - the most important thing that is still missing is proper handling of P_CheckPosition through arbitrary portals.
* Blocking lines above or below the current sector should only block if they actually intersect with the currently checking actor.
* Sectors above a ceiling portal should not change current floor information and vice versa.
* removed all code for dealing with z-displacing portals in the iterator loops. This would cause too many problems so I decided to scrap any provisions for allowing interactive portals with z-displacement. They will remain restricted to pure teleporter portals.
* changed spechit to carry a position along with the special line. If something is activated through an interactive portal this is needed to calculate movement.
* pass the abovementioned position to CheckForPushSpecial.
* collect touched portal lines in a second array analogous to spechit.
* use FMultiBlockThingsIterator in P_TestMobjZ.
(This is just a safety commit before doing some more extensive behind-the-scenes refactoring.)
Notable changes here:
* use the same logic for determining whether a 3D floor is 'below' or 'above' the actor as all the other functions.
* removed the broken code which tried to detect whether an actor was touching a steep slope. Better use P_LineOpening to find the correct planes and store the results.
* improved detection whether the slopes on both sides of a plane are identical, using the same data as for steep slope detection.
Note: This replaces AActor::intersects with a direct calculation. Although that function could be adjusted it'd mean some redundant distance calculations which are easily avoided.
- some consolidation in p_map.cpp. PIT_CheckLine and PIT_FindFloorCeiling had quite a bit of redundancy which has been merged.
- čontinued work on FMultiBlockLinesIterator. It's still not completely finished.
A big problem with this function was that some flags required setting up some variables before calling it and others did not. It will now set everything up itself so all initializations to AActor::floorz and ceilingz that were made before these calls (which were all identical to begin with) could be removed and the internal initialization logic streamlined.
This was to resolve some circular dependencies with the portal code.
The most notable changees:
* FTextureID was moved from textures.h to doomtype.h because it is frequently needed in files that don't want to do anything with actual textures.
* split off the parts from p_maputl into a separate header.
* consolidated all blockmap related data into p_blockmap.h
* split off the polyobject parts into po_man.h
- Check if a co-op start exists. If not, pick one at random.
- Don't telefrag other players when spawning in co-op games, since
you're allowed to move out of other players now.
'ceilingterrain' is needed because the top of 3D-floors refers to the model sector's ceiling, so in order to give a 3D floor a terrain it must be assignable to the sector's ceiling.
Note that although it is basically the same property, its actual function bears no relevance to its use in Eternity.
Issues with the old code:
* when calculating friction for a 3D-floor - swimmable or not - the 3D floor's top texture must be used. The previous version always checked the sector's floor texture, even though the top might as well come from the sector's ceiling.
* 3D floors never checked for the SECF_FRICTION flag at all. According to Boom specs, sector-based friction must be ignored if this is the case.
* Terrain based friction had a higher priority than the sector's own value.
Changed the rules as follows:
* if the sector's SECF_FRICTION flag is set (i.e. something explicitly changed the sector's friction), this value is used regardless of terrain settings.
* if this flag is not set, the terrain's friction is used, if defined, using the proper plane for 3D-floors.
* otherwise the default is used.
The previous version didn't detect some real mistakes in code which used operator& with the wrong flagset (for now 'converted' to the correcly equivalent counterpart, waiting for the proper fix).
The code never checked the starting position of the move and could be erroneously triggered in rare situations where the distance increased between actors but the hit boxes started overlapping because x or y distance got below the radius.
Changed it so that the code only gets executed when there's already an overlap before the move.
- changed monster unblocking logic to include players as well (i.e. a player being stuck inside another actor is allowed to move away from that other actor.)
- Rippers will rip through anything with an equivalent ripper level, or if their level is between or on the min and max ranges.
- If no min or max is defined, it simply checks if the monster's ripper level is lower than the missiles.
- Functions: A_SetRipperLevel(int level), A_SetRipMin(int min), A_SetRipMax(int max)
- Properties: RipperLevel, RipLevelMin, and RipLevelMax.
- RipperLevel: Applicable to monsters and projectiles.
- RipLevelMin and RipLevelMax are only useful on monsters.
- By default, all are 0.

- Added register reuse to VMFunctionBuilder for FxPick's code emitter.
- Note to self: Need to reimplement IsPointerEqual and CheckClass, which
were added to thingdef_function.cpp over the past year, as this file no
longer exists in this branch.
- Added THRUREFLECT, MIRRORREFLECT, and AIMREFLECT. All require REFLECTIVE to work.
- THRUREFLECT prevents missiles from changing course if reflected, and takes precedence over all reflective flags.
- MIRRORREFLECT causes missiles to perform a direct 180 turn-around.
- AIMREFLECT turns the missile back to the original shooter, and does not slow the missile down.
- Avoid doing the division if the result would be outside the ]0,1<<24[ range:
-- if the numerator is nonpositive, ie <=0, truncate the result to 0,
-- if the numerator is greater or equal than the denominator, the result will be outside the allowed range, hence truncate the result to 1<<24.
-- otherwise, the result will be inside the range. Knowing that the denominator is greater than the numerator, if the numerator has the last 24 bits non zero, the denominator can't be less than 1<<24, hence the denominator won't be truncated to 0.
- Add comment details to help who doesn't know math. Big deal!
-Fixed: ALLOWPAIN should not trigger pain states if the damage is 0, but still allow for infighting to occur.
-Fixed: an unneeded logic call was processing damage modification when it was 0 to begin with.
Actors will be excluded from damage/radius thrusting of all sorts by
explosions or damage of any kind. They will also never deal impact
damage to other enemies, nor will they damage themselves from being too
close to a wall.

- For maps like xtheateriii that expect non-blocking push lines to
activate when you are standing on them and run into a completely different
line, there is now this compatiblity.txt-only flag.
Corrected entries were blood would spawn inconsistently because of

DECORATE). Then you can use:
* Bounce
* Bounce.Floor
* Bounce.Ceiling
* Bounce.Wall
* Bounce.Actor
* Bounce.Actor.Creature
Partial matches work just like Pain states, so if an actor bounces off a floor and you don't
have a Bounce.Floor state, but you do have a Bounce state, it will use the Bounce state.
Conversely, if you only have a Bounce.Floor state but no Bounce state, then the actor will
only enter the Bounce.Floor state when it bounces on a floor; bouncing off anything else will
not cause it to change state.

infighting is disabled; let the normal conditions apply. Otherwise, you end up with situations

it. However, if the damage is canceled away, blood will still spawn for the original damage
amount rather than the modified amount.

and RTF_NOTMISSILE so that you can use A_Explode and A_RadiusThrust with non-missiles without
them telling P_RadiusAttack() that the target is the source.

respawns.
- Use doubles instead of floats, as appropriate, in PIT_FindFloorCeiling().
- Fixed: The second call to P_FindFloorCeiling() in A_RestoreSpecialPosition and P_NightmareRespawn()
must only consider 3D floors and midtexes.
SVN r3545 (trunk)
P_GetFloorCeilingZ(). I got confused because its bool parameter's meaning had been the
opposite of P_FindFloorCeiling()'s bool parameter before they got changed to flags.
SVN r3543 (trunk)
without resetting the actor's sector. The 3D floor checks in P_NightmareRespawn() and
A_RestoreSpecialPosition now use this.
- Fixed: P_NightmareRespawn() did its Z clamping before checking for 3D floors.
- Fixed: Respawning actors were not clamped to the ceiling.
SVN r3542 (trunk)
- Fixed: The 3D floors part of P_GetFriction() did not check for friction still being set to
ORIG_FRICTION, so it only worked with lower frictions.
SVN r3538 (trunk)
The initial spawn did not, so this can prevent respawns of things that were initially
spawned if they happen to intersect a wall.
- Fixed: Don't respawn actors inside the floor.
- Fixed: The final calls to P_FindFloorCeiling() in P_NightmareRespawn() and A_RestoreSpecialPosition
also need to pass true as the second parameter. (Because this parameter is onlyspawnpos, not
onlymidtex.)
SVN r3518 (trunk)
but their Z position would not actually be moved up, so the subsequent call to P_ZMovement()
would destroy it because it was in the floor.
SVN r3491 (trunk)
your movement was blocked, even if it wasn't that wall that blocked you. Note that this is just
a Z check against the actor and the floor and ceiling heights; it might still be possible to
goof it up, but the common case is fixed.
SVN r3414 (trunk)
Includes:
- Made the move tried from checking missile spawns ignore drop off height. This solves the Voodoo Gun ghostly civilian issue.
- Fixed: the NOTELEPORT flag is removed from Dehacked missiles which lose the MISSILE flag. This caused problems with certain special effects based on dehacked spawn cubes.
- Fixed: all Boom silent teleporters preserve relative height.
- support for palette independent particle colors if the renderer can handle them.
SVN r3329 (trunk)
A_DeathBallImpact uses these to avoid aiming at friends when the death ball
bounces. (The pointer is needed because the missile itself does the aiming,
not the player that shot it, and missiles are nobody's friends.)
SVN r3315 (trunk)
- added missing TRXTCOLOR_CYAN #define.
- changed bridge things to be completely immobile towards sector plane movement. This problem again reared its ugly head in 007LTSD where the oversized bridges got messed up by some opening doors and lowering lifts. Now any plane trying to move such a thing will get blocked. Moving these things by other means still works normally, of course
SVN r3013 (trunk)
- add a GetReplacement method to PClass to clean up some really ugly code
- Who wrote the 'kill' CCMD? The way it checked if two classes were identical was horrendously overcomplicated.
SVN r2601 (trunk)
- Restored some original Doom behavior that received complaints from users:
* reactivated the old sliding against diagonal walls code and compatibility optioned it with COMPATF_WALLRUN.
* re-added the original hitscan checking code using a cross-section of the actor instead of the bounding box, compatibility optioned with COMPATF_HITSCAN.
SVN r2340 (trunk)
- fixed memory leaks in SBARINFO and WAD loading code.
- added GetBloodColor and GetBloodType inline functions to AActor to wrap the GetMeta calls used for this.
SVN r2234 (trunk)
longer piggy-backs off of Hexen's puzzle item traversal but instead works like Strife,
using P_AimLineAttack() to find something to talk to and includes some slight left and right
"autoaim". I can think of a few consequences of this:
* Using puzzle items on actors has been restored to its original range of 64.
* Since talking now depends on P_AimLineAttack() instead of a line use traversal, you can
probably set up situations where you can talk to somebody that you couldn't talk to before
because some special line was in the way.
* You don't need to stick a guard flush against the wall to block players from using a switch
behind them, because now the autoaim will get the player.
SVN r2102 (trunk)
because it exposed a design flaw in the thinker system:
Having every single actor default to the highest available statnum means that
nothing can be placed in a slot where it is guaranteed to be run after all actors
have ticked. But this is required for any thinker that moves an actor
(i.e. AActorMover and DSectorEffect.) With DSectorEffect it just went unnoticed
because they were added at the end of the list so almost nothing they moved was
behind them in a thinker list. However, when an actor was spawned on a moving
floor it did not move smoothly. The default statnum is now 100 so that there's
sufficient slots above where such thinkers can be placed.
SVN r2060 (trunk)
it happened outside the moved actor's Tick function. This got particularly
obvious with moving skybox viewpoints (See Daedalus's MAP21 intro for a good
example.)
SVN r2059 (trunk)
But that's insufficient because it doesn't factor in any subsequent velocity
change that happens between the damaging and the next call to A_FreezeDeathChunks.
- fixed: The TimeFreezer did not freeze other players' controls in a
multiplayer game.
- fixed: DECORATE's 'gravity' property incorrectly messed around with the
NOGRAVITY flag.
- fixed: Hitscan attacks didn't check the puff's replacement for damage types.
SVN r2026 (trunk)
each other. PIT_CheckThing will return true under the following contitions
now:
* It was called from P_Move
* The actor that is blocking the move already overlaps with the monster
that is being moved.
* the move will take the 2 actors further apart.
SVN r2018 (trunk)
The editor number for player start spot 5 is now stored in the game info
so that there's only one place where this check needs to be done.
- Fixed: WIF_NOAUTOAIM only worked for projectiles unlike Skulltag's original
implementation.

Both Hexen and Heretic depend on such projectiles not doing it as do many
mods that create snow/rain effects plus any terrain splash mod.

unsigned integer that can use all 32 bits. They must therefore use
the unsigned mul instruction rather than the signed imul instruction.
- Fixed several signed/unsigned comparison and possibly uninitialized
variable warnings flagged by GCC.
SVN r1965 (trunk)
use a larger aiming range, and ignore non-targets in P_AimLineAttack().
- Added another parameter to P_AimLineAttack(): A target to be aimed at. If
this is non-NULL, then all actors between the shooter and the target will
be ignored.
SVN r1941 (trunk)
a different default terrain than a generic solid surface.
- added format char processing to A_Print(Bold) and all printable messages
that can be defined in DECORATE.
- Fixed: The railgun code ignored MF3_ALWAYSPUFF.
- added desaturated translations.
- added optional state parameters to A_ReFire and A_GunFlash and A_CountdownArg.
SVN r1921 (trunk)
- fixed: When a blasted actor collided with another one this other actor's
DONTBLAST flag was not checked.
- added a global DamageFactor actor property. All damage this actor takes is multiplied
by this factor in addition to damage type specific damage factors.
SVN r1915 (trunk)
- fixed: The BossCube could be blocked by floors and ceiling resulting
in incorrect movement. I changed it so that A_BrainSpit now sets the
MF5_NOINTERACTION flag for anything it spawns that has the MF_NOCLIP
flag. For travelling cubes active collision detection makes no sense
and only causes problems. This should also make the boss brain
work in the other games which previously were excluded by a game mode
check in the movement code.
- fixed: ACS's GetUserVariable did not work for the script activator.
- fixed: Moving floors could be blocked by 2 actors without MF2_PASSMOBJ
overlapping each other (common mapping bug, check Herian 2 MAP30.)
SVN r1891 (trunk)
- Derive PClass from dobject.cpp. This has one major ramification: Since the PClass
is not allocated until runtime, you cannot initialize any static/global data
structures with pointers to PClasses using RUNTIME_CLASS. Attempting to do so
will just initialize with a NULL pointer. Instead, you can initialize using
the address of the pointer returned by RUNTIME_CLASS and dereference that. By
the time you have an opportunity to dereference it, it will no longer be NULL.
- Sync CmakeLists.txt.
- Random fixes for problems GCC spotted.
SVN r1852 (scripting)
- added thing activation types for BUMPSPECIAL and USESPECIAL. Also added
a new ClearSpecial flag to the activation type.
- added MBF's code for dogs jumping down, controlled by the MF6_JUMPDOWN
flag.
SVN r1835 (trunk)
- Added more things from Gez's experimental build:
* MBF grenade and bouncing code.
* Arch Vile ghosts emulation (only for compatibility.txt.)
* Several MBF related compatibility options.
SVN r1821 (trunk)
* info CCMD to print extended actor information (not fully implemented yet)
* summonmbf CCMD.
* Beta BFG code pointer (but not the related missiles yet.)
* PowerInvisibility enhancements.
* ScoreItem with one significant change: Added a score variable that can be
checked through ACS and DECORATE. The engine itself will do nothing with it.
* Nailgun option for A_Explode.
* A_PrintBold and A_Log.
* A_SetSpecial.
SVN r1819 (trunk)
the various bounce-related flags spread across the different Actor flags
field into a single BounceFlags field.
- Fixed: P_BounceWall() should calculate the XY velocity using a real
square root and not P_AproxDistance(), because the latter can cause
them to speed up or slow down.

that were changed some time ago.
- fixed: The damage inflictor for a rail attack was the shooter, not the puff.
- Fixed: Floor and ceiling huggers may not change their z-velocity when seeking.
- Fixed: UDMF set the secret sector flag before parsing the sector's properties,
resulting in it always being false.
- Renamed sector's oldspecial variable to secretsector to better reflect its
only use.
- Fixed: A_BrainSpit stored as the SpawnShot's target the intended BossTarget,
not itself contrarily to other projectile spawning functions.
A_SpawnFly then used the target for CopyFriendliness, thinking it'll be the
BossEye when in fact it wasn't.
- Added Gez's submission for a DEHACKED hack introduced by Boom.
(using code pointers of the form 'Pointer 0 (x statenumber)'.
- fixed: Attaching 3DMidtex lines by sector tag did not work because lines
were marked by index in the sector's line list but needed to be marked by
line index in the global array.
- fixed: On Linux ZDoom was creating a directory called "~.zdoom" for
save files because of a missing slash.
- fixed: UDMF was unable to read floating point values in exponential format
because the C Mode scanner was missing a definition for them.
- fixed: The recent changes for removing pointer aliasing got the end sequence
info from an incorrect variable. To make this more robust the sequence index
is now stored as a hexadecimal string to avoid storing binary data in a string.
Also moved end sequence lookup from f_finale.cpp to the calling code so that
the proper end sequences can be retrieved for secret exits, too.
SVN r1777 (trunk)
- Fixed: Even though P_DamageMobj checked an attack's originator
for MF2_NODMGTHRUST the same check was missing from P_RadiusAttack.
- Fixed: A_MinotaurRoam should not assume without check that it was
called by a MinotaurFriend.
- Fixed: The Minotaur declared A_MntrFloorFire which it did not use.
- Fixed: All Spawnspot functions did not check for a spot tid of 0 as
the script's activator.
- Fixed: Friendly monsters ignored team association of their owning
players.
SVN r1770 (trunk)

velocity, and now it's known as such. The actor variables momx/momy/momz
are now known as velx/vely/velz, and the ACS functions GetActorMomX/Y/Z
are now known as GetActorVelX/Y/Z. For compatibility, momx/momy/momz will
continue to work as aliases from DECORATE. The ACS functions, however,
require you to use the new name, since they never saw an official release
yet.
SVN r1689 (trunk)
a Minotaur couldn't spawn floor flames when standing in water having its
feet clipped.
- added vid_vsync to display options.
- fixed: Animations of type 'Range' must be disabled if the textures don't
come from the same definition unit (i.e both containing file and use type
are identical.)
- changed: Item pushing is now only done once per P_XYMovement call.
- Increased the push factor of Heretic's pod to 0.5 so that its behavior
more closely matches the original which depended on several bugs in the engine.
- Removed damage thrust clamping in P_DamageMobj and changed the thrust calculation
to use floats to prevent overflows. The prevention of the overflows was the
only reason the clamping was done.
- Added Raven's dagger-like vector sprite for the player to the automap code.
SVN r1668 (trunk)
* BUMPSPECIAL flag: actors with this flag will run their special if collided on by a player
* WEAPON.NOAUTOAIM flag, though it is restricted to attacks that spawn a missile (it will not affect autoaim settings for a hitscan or railgun, and that's deliberate)
* A_FireSTGrenade codepointer, extended to be parameterizable
* The grenade (as the default actor for A_FireSTGrenade)
* Protective armors à la RedArmor: they work with a DamageFactor; for example to recreate the RedArmor from Skulltag, copy its code from skulltag.pk3 but remove the "native" keyword and add DamageFactor "Fire" 0.1 to its properties.
SVN r1661 (trunk)
- Fixed: P_LineAttack may not check the puff actor for MF6_FORCEPAIN because
it's not necessarily spawned yet.
- Fixed: FWeaponSlots::PickNext/PrevWeapon must be limited to one iteration
through the weapon slots. Otherwise they will hang if there's no weapons
in a player's inventory.
SVN r1659 (trunk)

- Changed screenblocks CVAR to be settable per game.
- Added SpawnSpotForced and SpawnSpotFacingForced ACS functions.
- Added pushfactor actor property.

- Added NOBOSSRIP flag. Note: we are now at flags6!
- Added SetSkyScrollSpeed(int skyplane, fixed speed) ACS function.
- Added THRUACTORS flag that disables all actor<->actor collision detection.
- Added DONTSEEKINVISIBLE flag for missiles that can't home in on invisible
targets.
- Added SFX_TRANSFERPITCH flag to A_SpawnItemEx.
- Added Ultimate Freedoom IWAD detection.
- Added GetAirSupply and SetAirSupply functions to ACS.
