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.
This was an issue since UTF-8 encoded text can contain -128 as part of
an encoding sequence which causes a lot of issues for the parsing code.
I could not find any indication why the original code didn't use null
bytes from the start and I also couldn't find any code that would break
because of this. If anyone knows why this was done like this please let
me know.
This allows to set string variables to localized values which will make
translating missions much easier.
This resolves one of the points mentioned in #1522.
This adds proper Unicode support by allowing the parse system to read
UTF-8 encoded files. The new mode is controlled by a mod option which
allows older mods to continue using the legacy text encoding.
That option changes the behavior of several systems in FSO. It disallows
the usage of Volition fonts since they don't support Unicode encoding
and changes a few usages of special characters to their unicode
counterparts of generic rendering solutions.
This fixes#1415.
I split this from #1331 to make reviewing these two changesets easier.
These changes convert all usages of const char* to SCP_string in the
static SEXP arrays so that the dynamic SEXP system can use SCP_strings
instead of having to allocate the strings and then somehow figure out
which strings must be freed at the end of the program.
This also converts the SEXP arrays to vectors so that new SEXP operators
can be added at runtime later.
There is nothing specific to OpenGL in that code anymore since it's all
handled in the shaders at this point. This will make the lighting
information available in the normal graphics code which allows to use
those values when filling the uniform buffer for the model rendering.
Back when I added the "same emp time for capships" flag in SVN r9540, I neglected to multiply the EMP time by 1000, as the EMP disruption time for fighters is specified in seconds but the time for capships is specified in milliseconds. So, using this flag would cause capships to suffer EMP disruption for almost no time at all.
This PR fixes that, and also extends the explosion-effect sexp to specify this parameter. And I also cleaned up the fireball section by calling eval_num(n) just once instead of several times.
When the OPF_NUMBER and OPF_POSITIVE behaviors were made more robust, it exposed a latent bug in the play-sound sexps. These had OPF_POSITIVE where they should have had OPF_NUMBER. With this fix, sounds can now play from all coordinates, positive or negative.
There is a bug where, when displaying an error message with a sexp node that contains a variable, the code will trigger an Assertion in the process of printing the error message. This is because it tries to transcode the sexp variable from name to index, when that has already been done further up the pipeline. This fixes that by adding a quick test to see if the expected variable name is an integer.
Time-undocked will cause FSO to freeze unless you know what you're doing, so this PR fixes some gotcha areas. Inspired by The E's rant on Discord which, while not 100% correct, did indicate some areas for improvement.
1) Set the default "number of times docked" argument to 1 when the sexp is created in FRED, same as with the has-[un]docked-delay sexps
2) Catch any <= 0 counts when the sexp is called in FRED and set them to 1. (This was done for other sexps which used mission_log_get_time_indexed, but was not done for time-[un]docked for some reason.)
3) Add an assertion to mission_log_get_time_indexed as a last resort to guard against invalid counts.
This was reported by @AxemP who wanted to have leading tabs in a text
line. However, split_str removed those characters by default since it
ignores leading whitespace. To fix that unexpected behavior of
gr.drawString I added a new paramter to split_str which disabled
whitespace removal and enabled that flag for the scripting function.
That should not be a problem for existing scripts since the expected
behavior would be that leading whitespace remains in place and since we
have not received any bug reports about missing white space I'm going to
assume that no one has used the function like this before removed those
characters by default since it ignores leading whitespace. To fix that
unexpected behavior of gr.drawString I added a new paramter to split_str
which disabled whitespace removal and enabled that flag for the
scripting function.
That should not be a problem for existing scripts since the expected
behavior would be that leading whitespace remains in place and since we
have not received any bug reports about missing white space I'm going to
assume that no one has used the function like this before.
sexp_manipulate_colgroup() was using logical NOT when it should've been using bitwise NOT, meaning that removing any collision group would remove all collision groups.
This renames the functions exposed by flagset so that it's clear that
64-bit values are returned. This also cleans up usages of wrong format
specified when that value is printed which caused some issues in the
past.
This should also fix#1336.
This should make sure that the environment map is only redrawn if
necessary. In my case that should improve frame times by around 1ms for
the normal case when the environment map doesn't need to be redrawn.
