- Converted P_MovePlayer and all associated variables to floating point because this wasn't working well with a mixture between float and fixed.
Like the angle commit this has just been patched up to compile, the bulk of work is yet to be done.
Patched up everything so that it compiles without errors again. This only addresses code related to some compile error. A large portion of the angle code still uses angle_t and converts back and forth.
Links through sector portals are not done because nearly all the checks can be performed without doing this so if it works without there's no need to add more processing time.
Will have to see if there's cases left where such a link is needed and if so, whether there's better options to do it.
For line portals such links are necessary to have proper collision detection with actors that are currently transitioning the portal.
Notes:
* It is actually not enough to disable the early-out condition for the current block if there's a portal. It must be disabled for the entire rest of the trace because otherwise the collected lines never get processed.
* The block bounds check cannot be done globally with portals in the game. The actual trace can easily end up outside the blockmap bounds if portal offsets are factored into the distance between the two actors.
- fixed: P_FindFloorCeiling set the floorsector for a new ceilingheight.
Note: P_DrawRailTrail still needs to be changed, at the moment rail trails through portals will not work correctly.
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.
- added portal offsetting to all AproxDistance, AngleTo and Vec*To members of AActor.
- optimized displacement retrieval so that the most common case with no offset retrieves a constant null-vector which can be optimized away fully by the compiler.
- early out in P_GetOffsetPosition if there's no portal lines nearby, so that the common case can skip the traverser completely even on maps with line portals.
- 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.
* the temporary checking arrays are now static
* the array that gets the returned values only starts allocating memory when the third touched sector group is found. The most common cases (no touched portal and one touched portal) can be handled without accessing the heap.
- did some streamlining of AActor::LinkToSector:
* there's only now version of this function that can handle everything
* moved the FIXMAPTHINGPOS stuff into a separate function.
* removed LinkToWorldForMapThing and put all special handling this function did into P_PointInSectorBuggy.
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
Note about A_SkelMissile: The direct change of the missile's position was changed to use SetOrigin. If this is later supposed to be portal-aware, such direct coordinate changes are a no-go to ensure that everything is properly maintained.
This contains some advance work for handling line-to-line portals in A_PainShootSkull.
This function is special because it performs a map check itself instead of using one of the common functions from p_map.cpp, like most of the rest of the game code.
This commit is just preparation for upcoming changes to completely encapsulate the coordinate info in AActor because I'm going to have to work with an altered version of actor.h that cannot be committed without breaking the engine.
With this file present in the repo before work is started the changes can be committed piece by piece.
'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.
- Added 'threshold' and 'defthreshold' to DECORATE expression exposure.
- ChaseThreshold sets the default threshold for how long a monster must chase one target before it can switch targets. Default is 100, must not be negative.
- A_SetChaseThreshold can be used to alter the current or default threshold of an actor <pointer>.
- Changing current threshold has no effect on what the default will be once it hits 0 and something makes it infight with another.
- This only affects damage calculations being received by the end result. If the original damage was not a million or more, from the start, it will not hurt invulnerable-flagged or kill buddha-flagged monsters.
- Fixed: Damage was inconsistent by the time the function checked for player cheats/invulnerability and (monster and player) buddha, yet monster invulnerability checked the original damage prior to factor processing. This means a damage source that intended to damage another below the threshold could accidentally increase with a powerdamage multiplier or the recipient with a weakness for it, resulting in invulnerability/buddha foiling. Now, checks for telefrag damage using the raw original value on player godmode, player/monster invulnerability and buddha.
Introduce AActor::TakeInventory, which unifies DoTakeInv from ACS and DoTakeInventory from Decorate, and AInventory::DepleteOrDestroy, which is extracted from the DoTakeInv core function, and use both where they're needed.
I don't know if the differences between DoTakeInv and DoTakeInventory were intentional, so I kept both behaviors.
- 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.
- New properties include TeleFogSourceType and TeleFogDestType.
- TeleFogSourceType is the fog left behind where the actor teleported away from.
- TeleFogDestType is the fog the actor sees when it arrives at its destination.
- Added A_SetTeleFog(<oldpos>,<newpos>) -- oldpos sets TeleFogSourceType, newpos sets TeleFogDestType.
- HITTARGET, HITMASTER, and HITTRACER.
- A missile that dies hitting an actor will set this impacted actor as the new target/master/tracer, depending on specifications.
- 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.
-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.
Monsters with this flag can enter pain states, regardless of
invulnerability or damage absorption.
- Fixed: god2 cheat wasn't being considered for drowning and thrusting.
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.
