OpenTomb is a cross-platform reimplementation of classic Tomb Raider 1—5 engines that were developed by now defunct Core Design. The project does not use any old Tomb Raider source code, because all attempts to retrieve sources from Eidos / Core were in vain. Instead, everything is being developed completely from scratch. However, OpenTomb uses certain legacy routines from such unfinished open-source projects as OpenRaider and VT project (found at icculus.org), plus it incorporates some code from Quake Tenebrae. OpenTomb supports not only classic Tomb Raider levels, but also custom levels built with TRLE and Dxtre3d level editors.
OpenTomb was in a stage of intensive development for all the past year, but until now, we haven't touched the sacred ground of triggers and entities interaction. Now the time has come, and for the first time we can see interactive (yet very rough) environment in City of Vilcabamba. Consider this a milestone, because now you can really finish the level with a little help of noclip.
Unlike original Tomb Raiders, where we had predefined and hardcoded routines for each entity type, OpenTomb allows you to program every single entity in game - all the code is done in Lua scripts. There is more to follow - timed triggers, pick-ups - and, of course, inventory!
