382a6e8b9f - link actors to touching line portals, for use by the renderer. 2016-04-21 22:59:07 +02:00

082042818b - refactored sector portal data so that it does not rely on actors.
This is necessary because otherwise the level data cannot be serialized before the actors.

3ed7a25d61 - added polyportal offset updates.
- removed the nodebuilder message for splitting polyobject subsectors because it is no longer relevant.

9412ce45d6 - floatified portals.cpp and most of p_maputl.cpp. 2016-03-31 16:52:25 +02:00

26ff2f73d7 - floatified P_TryMove and the sliding and bouncing code. 2016-03-27 13:29:58 +02:00

1877eca2ab - more floatification of p_map, plus some stuff used in those functions. 2016-03-27 01:06:54 +01:00

1125101b37 - floatified AActor::Prev plus the stuff using it.
- rewrote some coordinate functions in AActor to use real float math instead of converting back and forth between float and fixed.

a652c061f6 - converted g_strife to full floating point use, except the floor height changing stuff in A_LightGoesOut. 2016-03-22 12:42:27 +01:00

51b05d331d - replaced AActor::vel and player_t::Vel with a floating point version.
- 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.

671291227e - first stage of converting actor angles to float complete
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.

3c25b2c066 - some redesign of P_CheckSight to handle portals.
Portal stuff not tested yet.

14a0567343 - optimized the portal translation functions by precalculating the rotation angle, sine and cosine. 2016-03-03 11:58:04 +01:00

07771bd56e - changed parameter of P_GetOffsetPosition to a simple coordinate so that it can be used for other things than actors. 2016-02-29 16:29:51 +01:00

60c2a55ec4 - added P_GetOffsetPosition calls to all needed functions. 2016-02-26 11:52:53 +01:00

d46e109a5b - prevent Visual C++ from making stupid code. 2016-02-26 11:52:52 +01:00

eafd2519b4 - fixed a few incorrect uses of AngleTo function.
- 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.

c7bce8b346 - added a special portal blockmap. This only contains all lines which have a crossable line portal assigned. This is to speed up offset calculations because those are quite frequent and would be too inefficient with the full blockmap.
- made some minor changes to FPathTraverse so that the Add*Intercepts methods can be virtually overridden.
- removed the PortalTracer class because in its existing form it was too costly. Replaced with a P_GetOffsetPosition function that does the minimum required work to get to the translated destination and that's better suited for being called from the Vec*Offset methods. Other use cases will require some changes to FPathTraverse anyway, or some wrapping class like the FMultiBlock iterators.

cb0e7c6ca5 - fixed some issues with P_FindFloorCeiling rework. 2016-02-20 02:22:08 +01:00

02d7572343 - some header dependency cleanup so that it is no longer needed to include portal.h to get the inline functions. Portal.h has been reduced of most dependencies now so that including it is cheap and can be done in other headers.
- some consolidation in p_map.cpp. PIT_CheckLine and PIT_FindFloorCeiling had quite a bit of redundancy which has been merged.
- Ĩontinued work on FMultiBlockLinesIterator. It's still not completely finished.

3841a5f626 - implemented FMultiBlockLinesIterator for checking a position across portals. This is not fully tested yet. 2016-02-19 10:39:40 +01:00

8d53f6176e - fixed conditions for PortalBlocksView. Created a new function PortalBlocksSight that's relevant for playsim-related sight checks. 2016-02-16 22:57:03 +01:00

1b88052bba - started refactoring ZatPoint calls which need to be portal aware.
To summarize, anything that just works with map geometry doesn't need to bother, as does the renderer. (i.e. nearly all r_* files, p_floor.cpp, p_ceiling.cpp et.al)
But all calls that are somehow related to actor positions need to be made aware of potential portal transitions:

 * added FloorAtPoint, CeilingAtPoint and PlaneAtPoint methods to sector_t, which can be used to calculate a plane's height with relation to a given actor, even if that actor is on the other side of a portal.
 * added HighestCeilingAt and LowestFloorAt methods which traverse all ceiling/floor portals until they find an impassable plane.

22e8678903 - refactored P_CollectConnectedGroups to avoid frequent heap allocations for the common cases
* 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.

f24bf7e622 - separated FCheckPosition and its FPortalGroupTable substructure into its own header because this was creating too many dependencies on other headers with FCheckPosition in p_local.h and FPortalGroupTable in portals.h. 2016-02-15 13:40:31 +01:00

405db83393 - added a function which collects all portal group an actor would touch if standing in a given position. 2016-02-15 00:53:59 +01:00

d5a1004c41 - some preparations for portal stuff:
* set up linked sector portals so that everything that will eventually have to be considered is present, even though the software renderer currently can't handle those adequately.
* tag all skybox things with a type so that they can easily be distinguished at run time.
* fill in the linked portal types in xlat/eternity.txt.

77b9f41dff - added Line_SetPortalTarget action special so that portals can be assigned new targets. Setting the target to 0 disables the portal.cpp. Static linked portals can not be reassigned.
Please note that these still require the portal to be set up in the map with Line_SetPortal. It will not create a new portal if none exists on any line with the given ID.

94b7ef72ca - more cleanup on portal implementation:
- store portal data in a separate structure.
- store portal data in savegames because some of this will be changeable later.
- run a cleanup pass after all portals have been created to weed out broken ones.
- add a definition type that's compatible with Eternity Engine's line portal types.
- swapped arg[2] and arg[3] of Line_SetPortal, because the type is more significant than the alignment.

9eaefc3685 - initialize portals with all other static line specials instead of doing it separately in P_FinishLoadingLineDefs when the map isn't fully set up yet.
- replace all float use in portal.cpp with doubles.
