b3f7a57518 - yet another case of adding a workaround to preserve a side effect in Doom's original movement code that's bound to be inadvertently exploited:
When a spechit results in teleportation, P_TryMove never accounted for that, so that subsequent spechits either failed or succeeded, depending on where the teleport ends up.
With portal-aware positions stored within the spechit this no longer worked, so some handling is needed to revert to the original behavior in case there's no portals to consider.

The ideal solution would have been to stop checking spechits (or to block further teleports) once this happens but the likelihood of some old maps depending on this is high.

03118d441f Don't use _FPU_GETCW if it won't do what we want
- _FPU_GETCW is defined for more than just x87. Don't use it if the
  control word for the target architecture doesn't support _FPU_EXTENDED
  or _FPU_DOUBLE defined, e.g. pretty much anything but x87. If I had been
  using glibc on PowerPC instead of Apple's libc, I probably would have
  noticed this sooner, since _FPU_GETCW is part of glibc.

76489e7638 More gracefully handle travelling to a map without matching player starts
- First, don't crash when travelling to a map in a hub that doesn't have
  any player starts that match the position given to Teleport_NewMap (or
  equivalent).
- Seconed, move the player to the location they were at when the left the
  level. At least that way, they shouldn't be in random geometry or off
  the map entirely.

48b6b6e057 Clip portals to viewheight, not screen height
- Aside, but is this even neccessary? The arrays being copied from should
  already be clipped properly.

0a1e22aa7a - fixed: FPathTraverse::init kills the intercepts array so PortalRelocate needs to store the line before calling that function. 2016-03-08 18:45:52 +01:00

The patch content was destructed and then accessed when loading DeHackEd file of old/unsupported version

899389e6a4 - link actors into blockmap through linked line portals.
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.

1815b076ee - don't show the IWAD picker upon restart. This doesn't work with fullscreen mode. Instead just pick the first IWAD from the list until a better solution can be implemented.
- handle a 'restart' CCMD a bit more controlled. Instead of throwing an exception in the CCMD handler it now just flags D_DoomLoop to return.

If the exception is thrown within the CCMD this can easily happen deep inside the renderer when it calls NetUpdate. But since the software renderer with its use of global variables is not equipped to be yanked out of lile this it could leave broken data behind that caused glitches or even crashes on subsequently played maps.

e11a0986ce - encountered a strange crash that after changing a map, InSubsector was not NULL and pointing to invalid data. So let's better NULL this variable explicitly each time a render loop is started. 2016-03-08 12:27:01 +01:00

f852ead99a - fixed: The initial check for ceiling and floor portals must be done when the trace's start position and its sector has been calculated. SightCheck::init is too early for that. 2016-03-08 10:44:03 +01:00

f35d966799 - don't allow any ceiling portal that has a lower position than a floor portal in the same sector. The will inevitably lead to problematic situations. 2016-03-08 10:09:02 +01:00

2cd74118f6 - fixed sight checking through portals.
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.

cc2885c2de - fixed int/fixed_t mixup with P_RadiusAttack's 'bombdistance' parameter. (Why is this thing even an int...?) 2016-03-07 22:05:19 +01:00

f82c217047 Fixed: In multiplayer, players could spawn at voodoo doll starts
- This could happen in co-op games that did not have enough player starts
  for all the players spawning. Voodoo doll starts were not excluded from
  the set of possible starts as they should have been.

e277fbe81d Fixed some incorrectness with some Hexen crushing specials
- The following Hexen specials all stop 8 units above the floor:
  * Ceiling_CrushRaiseAndStay
  * Ceiling_CrushAndRaise
  * Ceiling_LowerAndCrush
  We only and Ceiling_LowerAndCrush correct. Clearly, I should have paid
  more attention when the Hexen source was released for the parts that I
  had already reverse engineered.

af50a79e55 - Fixed: ScaleY was not defaulting to ScaleX when specified as 0, which is how the behavior originally was in 2.8. This behavior can now be toggled with a new boolean, 'usezero'. 2016-03-07 09:02:34 -06:00

8f71906fc3 - added portal support to P_RadiusAttack.
This currently only works for linked portals. For other types some major refactoring may be necessary because it not only requires multiple passes of P_RadiusAttack but also an alteration of how sight checks work.

7d7112f427 - added portal support to A_ThrustImpale, P_PushUp and P_PushDown. 2016-03-07 00:17:52 +01:00

5175d56129 - made adjustments to P_LineAttack and P_RailAttack to deal with altered angles by passing through a non-parallel portal.
- 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.

90553bb61c - deal with portals in P_AimCamera.
This will most likely need some more testing and refining but at least it should work through line portals now.

a0b2915b8f - added a heightsec change when aborting the main trace due to having found a target in a subtrace.
- be a bit smarter about what to copy from a subtrace. There's 3 distinct pieces of information here: The hit itself, the CrossedWater setting for Boom-transfers and the CrossedWater setting for 3D floors.

Note: Ideally this should return all water hits it can detect, not just the first one.

74592334e4 - fixed return conditions of Trace() so that it always returns something valid. Due to the portal related changes the default initialization for TRACE_HitNone must be inside TraceTraverse. 2016-03-06 01:41:52 +01:00
Christoph Oelckers

983e8bc6a5 - explicitly check NAME_Null in P_FindTerrain so that it cannot get rendered inoperable by mods which hijack this name. This name must be reserved so that there is some means to disable a sector's terrain. 2016-03-05 22:39:53 +01:00
Christoph Oelckers
97577dc2d7 - added sector portal support to Trace()
Note that at the moment only the function itself has been changed, the calling parts still need to be redone.

c455c60480 - fixed: calculating open.range requires signed math.
- fixed: FMultiBlockLinesIterator initialized continueup twice but forgot continuedown.
- fixed: One of the debug messages in P_AimLineAttack was missing an if (aimdebug).

e290bc6fd0 - fixed: In Hexen, ThrustThing can not be triggered from the backside of a line.
This gets only activated when the HEXENHACK flag is set. For ZDoom maps there is a specific line flag to handle this condition explicitly.
