This is specifically for OPF_SHIP. Currently if you specify a LuaSEXP with OPF_SHIP, it only works for ships that are present in the mission when the SEXP is called. This is my attempt at a LuaSEXP parameter variant that will return a valid ship name regardless of the ship status. It required a bit of finagling the existing API.
This adds a "clear-debris" SEXP with a new system for declaring SEXPs
outside of sexp.cpp. This makes it easier to keep code modules self
contained since they do not need to export previously private
functionality just for having missiong being able to interface with it.
This is mostly a proof-of-concept which only supports basic parameter
types (booleans and integers).
This will ensure that Lua functions will always be executed in the
correct Lua state. Since we now have multiple threads (which are
different lua_State objects) it is possible that the current code could
execute a Lua function in the main state instead of the thread that is
currently executing. This can lead to weird behavior and probably also
to issues inside Lua.
NaN should propagate through the SEXP tree, but not all SEXPs do this properly. The problem was made worse after I introducted `eval_num()` which silently ignored NaN values. This commit adds new boolean arguments to `eval_num()` to flag NaN results, and changes all calls of `eval_num()` to properly handle the new arguments. Additionally, this adds `eval_nums()` and `eval_array()` functions to more smoothly handle cases where many numbers appear in a row.
Travis CI recently added support for running builds in Windows. This
adds support for testing compilation on Windows using that feature.
The newer version of Visual Studio and MinGW required some code changes
and an update of Google Test which is included in this commit.
This can be used for mark parts of the code which should be unreachable
in normal execution. In debug mode, if such a statement is reached an
Error dialog is shown which aborts the execution. In release mode the
macro is replaced with a compiler specific expression that lets the
compiler know that this part is unreachable which allows it to optimize
the code better.
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.
