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.
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.
This adds a new class which allows to create type safe resource handle
types. At the moment, the engine uses ints pretty much everywhere for
providing handles to resources created by the specific subsystems. Since
all ints are the same to the C/C++ typesystem it is perfectly legal to
pass a sound handle to the graphics API as a buffer handle which will
obviously cause issues.
This adds a new type called "ID" which is a wrapper class for a generic
handle but with added type safety. An instance of this class cannot be
passed to a function expecting another type of handle which provided
compile-time type safety for these APIs.
As an initial test I converted the game sound handles to this new type.
I already found a bug in the mainhall system thanks to this new type.
The mainhall used the game sound handles as sound instance handles which
probably meant that that specific code never really worked right. I
removed the code since there was no better alternative for fixing it.
This is pretty much an exact copy of the mission save code of FRED2. I
removed the campaign save code for now since it requires some
interactions with the campaign editor which does not exist yet.
Synchronize the two subsystem-of-ship checks in sexp.cpp and sexp_tree.cpp. Mostly this is just adding OP_BEAM_FLOATING_FIRE to sexp_tree.cpp because whoever added that sexp forgot to add it there.
Returns true if the ship is in a turret's FOV, false otherwise. Requested by JSRNerdo. Uses the object_in_turret_fov internal function which is the same one used by the turret code when it checks whether it can fire.
