This can be used by the various subsystems for cleaning up Lua
references before the Lua state is destroyed. This avoids having
dangling references to the Lua state which would cause segfaults later
on.
The first subsystem to use this is the dynamic SEXP system which had
dangling references due to keeping Lua references to the SEXP functions.
This fixes#1954.
Bad data can cause the name search to fail, and if change-ai-class was called with an invalid AI class, it could cause later invalid array accesses (using an index of -1).
Previously, these two SEXPs could only be used in single-player; now they can be used in multiplayer. (This now allows Admiral MS's ship save/load script to work in multiplayer too.)
Inspired by Parias's patch included in the FSPort Co-Op Mod Beta (https://www.hard-light.net/forums/index.php?topic=88385.0) though with some modifications.
The code already only recomputed collisions if we moved a ship or a wing, but this further optimizes things so that only ships or wings that can collide will cause a recomputation.
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 adds a new AI goal which is equivalent to play-dead except that it "sticks". It doesn't clear the goal list
so it will continue playing dead until the goal is removed or another goal with a higher priority is added.
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.
The warp-effect SEXP can now specify other animations from fireball.tbl that are not necessarily the standard or Knossos animations. Additionally, the SEXP can now specify the duration for the opening and closing of the warp effect.
Nobody ever thought to add a reset-post-effects SEXP to complement set-post-effects, so this remedies that. Also, a few minor edits were made to the scripting documentation.
The special value DIRECTIVE_WING_ZERO (defined to be -999) is used to
signify to the directives system that an is-destroyed SEXP was found
which specified an empty wing. However, if a second is-destroyed-delay
SEXP is present in the same directive then the count of the parameters
is added to -999 which makes means that the directives system then
displays it on the HUD as a negative number.
This fixes that by resetting the counter to 0 if a second SEXP
encounters the special value which fixes the issue in the supplied test
mission. There are probably other edge cases when using multiple
is-destroyed SEXPs in a directive so I added a warning to the SEXP help
which lets the mission designer know that it is preferable to specify
multiple parameters instead of using multiple is-destroyed SEXPs.
This fixes#1722.
The routine ai_turn_towards_vector() had an unused parameter (frametime)
and it has been removed.
Each of the instances where this routine is called have also been updated
to reflect the parameter removal. As this resulted in the routine
swarm_update_direction() suddenly having an unused parameter, that routine
and the places where it is called have also been updated (remove
unused parameter).

The cap-waypoint-speed sexp only works for speeds above 0; this PR changes the documentation to clarify that. I also tweaked an if() block in ship_return_time_to_goal because it used a >=0 comparison whereas every other comparison used >0. (This is only for consistency, because the >0 check is used before this point would be reached.)
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.
The code did not account for unicode escape sequences when inserting
scrambling characters which distorted the text and fequently caused
invalid UTF-8 sequences to appear in the text. This fixes that by
using the text iterators already present in the game code. I needed to
rewrite the logic of this block a bit since the previous logic could not
be converted to the way we need to handle unicode sequences at the
moment.
This fixes#1720.
These operators used to warn and return NAN if they were given a bit index out of range. For FREDding convenience, out-of-range bit indexes are now a no-op. This is particularly helpful in the situation where a FREDder needs to evaluate an extended bit array, one 32-bit chunk at a time, e.g.
0-31 bits: offset 0
32-63 bits: offset -32
64-95 bits: offset -64
96-127 bits: offset -96
Because the sexp system always evaluates every argument, three out of four branches were always evaluated with invalid bit indexes (negative or too large) even if the sexp logic only used one branch. The new method silently bypasses this behavior.
