TombEngine 1.4 scripting interface
Welcome to the TombEngine scripting API. This is a work in progress and some information might be wrong or outdated. Please also note that this is primarily a reference document, not a tutorial, so expect descriptions to be fairly sparse.
At the time of writing, there is a tutorial describing the basics of Lua, as well as a number of example scripts, on the TombEngine website.
Module Hierarchy (boring but important)
Other than the "special tables" (GameVars, LevelVars and LevelFuncs), every module described herein is held in a master table called TEN. For convenience, these modules and classes are automatically put in the global table. For example, you can call GetMoveableByName either of these two ways:
local door = TEN.Objects.GetMoveableByName("door_type4_14")
local door = GetMoveableByName("door_type4_14")
Always check logs/TENLog.txt
If you are scripting levels, TombEngine will often kick you back to the title screen, even if errorMode (see Flow.Settings) is set to ErrorMode.WARN or ErrorMode.SILENT.
This might get annoying, but it's on purpose. If your Lua script contains a syntax error (e.g. you're missing end at the end of a function), the Lua interpreter will not be able to continue running the script. If it tried to keep running, you'd probably see some pretty strange behaviour, and would possibly get a crash regardless.
If this happens, check logs/TENLog.txt and look for an error message with the word "unrecoverable".
Enjoy.
