This was previously used for allowing scripts to set arbitrary values on
scripting objects. However, it was used by only a few scripting
functions and, as far as I know, no script uses this features.
This removes that feature which simplifies the code ade_index_handler
of.
This also simplifies the code that handles the userdata for libraries
provided by FSO.
This maintains the type information which can be used for enforce
const-correctness and also for implementing more advanced ways of
handling the type information.
Ideally it wouldn't be an optional argument at all, but that would break backwards-compatibility, so instead it'll just return an invalid ship handle instead of calling ship_create() with a class of -1. In addition, the Assert from ship_create() meant to guard against invalid ship_type values is now an Assertion that actually says what the invalid value of ship_type was, to make future debugging easier.
This adds a scripting API which can be used for adding and removing
background from a mission similarly to the existing SEXPs but with full
support for floating point numbers.
This was requested by Axem on Discord.
Since atoi return 0 on error the code tries to access the waypoint list
with index -1 which causes an assert in the lookup code. This fixes that
by using the error detection capabilities of strtol.
This add a system for adding generic instances of the DynamicSEXP class
to the SEXP system. The only implementation at the moment is the LuaSEXP
which is used by the mn.addSEXP lua API to allow Lua to add new SEXPs.
Since this requires that FRED also runs lua scripts I added a mod table
option to enable scripting in FRED. Since the current scripts are not
built with FRED in mind it would likely break all these scripts if FRED
would be opened with normal scripting enabled.
This fixes#1320.
