Christoph Oelckers	3841a5f626	- implemented FMultiBlockLinesIterator for checking a position across portals. This is not fully tested yet.	2016-02-19 10:39:40 +01:00
Christoph Oelckers	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.	2016-02-16 12:51:10 +01:00
Christoph Oelckers	b9037ef3ee	- added a check to detect self-referencing sectors in the portal setup code because those are problem cases.	2016-02-15 21:49:46 +01:00
Christoph Oelckers	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
