Every g3_start_frame must have a matching g3_end_frame. Thus, a return
in the middle of a function after an opening g3_start_frame must make
sure to call g3_end_frame before it leaves to avoid a dangling frame
context.
As described in the bug report at
https://github.com/scp-fs2open/fs2open.github.com/issues/1827
a floating point rounding issue could be the trigger for the problem.
Removed a lot of unused functions.
This is mostly a cleanup of a prior refactoring.
There where a lot of unimplemented functions remaining from renaming.
Removed several outcommented parts of code.
This adds a mission file option for ships which allows specifying a
different string which should be used for displaying the name of the
ship to the user. This name will not be used in SEXPs or other ship
lookup functions so it can be freely translated and two ships can also
have the same display name.
The new feature can be used by adding $Display name: <string> after $Name
for a ship in a mission file. I think I added proper support for FRED
(and qtFRED) so that this new value is properly saved but it would be
great if someone could test that.
This implements one of the features requested in #1730.
This is similar to the other changes I already posted. Here the sound
instance handles are converted to their own handle type which will make
it easier to use the sound API.
This adds support for rendering models using thick lines (that means
lines wider than 1 pixel) which is required by the hardpoint HUD gauge.
This feature was present before the switch to OpenGL code and had to be
removed since the core profile does not support rendering lines wider
than 1 pixel.
This uses a geometry shader for converting all the triangles from a
model to 3 quads along the triangle lines which are as thick as set by
the model renderer. Geometry shaders are quite slow if they generate a
lot of geometry (and this generates 4 times the usual amount of geometry
in the shader) so it's probably not a very fast rendering operation but
it is only needed once per frame so it shouldn't be too bad.
I also added support for the RenderDoc API since I needed that for
debugging and it might be useful in the future. It will only become
active if RenderDoc is actually attached to the process so in most cases
the new code will do nothing.
I also fixed a few issues where the internal char array was used as a
mutable string which changed the string after it was parsed which is not
good(TM).
This also replaces all user-facing occurences of usages of name to use
the new function so that the correct, possibly translated, name is displayed
to the user.
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.
The previous fix to the weapon orientation failed to account for the
change from local to global space for the weapon position. This fixes
that by rotating the model positions to world space before submitting
the render call.
This fixes#1647.
There were actually multiple issues here. The addition of color mask and
stencil state to the material system overwrote the state set by the
hardpoint renderer so the stencil buffer was never written or read
correctly. I fixed this by introducing three new model render flags
(there were a few open slots in the bit mask so I used those) which set
the correct state using the material system. That also makes setting up
the rendering environment much easier.
Second, gr_opengl_stencil_set used mixed up parameter values which were
probably broken when I introduced more detailed stencil state tracking.
I restored those values to how they were in 3.8.
This fixes the other issue reported in #1640.
The code previously used the matrix stack for handling the orientation
or the weapon models. That is no longer supported by the model renderer
(since it would make handling the transforms harder for no real reason).
I fixed the issue by passing the object orientation directory to the
model render function.
This is a fix for one of the problems mentioned in #1640.
All transformations are now handled by shaders so there is nothing
special going on in the graphics API specific code anymore. Since model
uniform buffers require access to these matrices I moved the matrix
handling out of the graphics API code.
This assertion could apparently be hit if a ship was vanished (e.g. with ship-vanish) in the middle of talking. Rather than making the vanishing code aware of (and responsible for) Message_shipnum, it seemed simpler to just make hud_show_message_sender() clear the invalid shipnum itself.
Since the rendering code always accesses all four frames it must be
ensured that they are all present. Currently, there is a bmpman
assertion about an invalid handle if the animation does not have enough
frames. This fixes that by warning about that and then resetting the
bitmap handle to -1 so that the rendering code doesn't try to use the
handle.
Changes "A-Objects" to "OBJ_INDEX(A)" (not sure why that one didn't generate warnings, but whatever), removes a redundant should_be_ignored() call (it will have already been called for that ship for the code to be in that block in the first place), and adds an assertion to make sure that the jnp iterator is valid before trying to dereference it.
See also my comments on #762. The flag is almost entirely redundant, so this PR removes it in all instances where it's used in the ballistic primaries code. There are one or two places where removing it was not a no-op, so I adjusted the rest of the code accordingly (most notably in the parsing validation when it checks that primary weapon cargo has been assigned). I also added a few divide-by-zero checks and slightly tweaked the support ship rearm code. The use of the SIF_BALLISTIC_PRIMARIES flag in the ingame_join code was replaced with a dummy value to avoid bumping the multiplayer packet version number.
This introduces a new mechanism for handling bit flags. Instead of using an int (or two, or three) to write bits into, this uses the std::bitset in a wrapper class that accepts an enum class as input. This means that certain classes of errors we've had a few of in the engine, where a coder used the wrong set of flags or checked them against the wrong variable (SF_STEALTH vs SIF_STEALTH, for example) can now be detected at a compiler level rather than not at all.
This allows to use standard TrueType Fonts for text rendering in FSO. It uses the NanoVG library which provides the ability of drawing 2D shapes. This library is used for most 2D operations now and can also be used directly by using the PathRenderer class.
Replaces calls to double-precision floating point trig functions with
calls to single-precision floating point trig functions as follows:
cos() -> cosf()
sin() -> sinf()
tan() -> tanf()
acos() -> acosf()
asin() -> asinf()
atan() -> atanf()
This allows the compiler to avoid generating unnecessary instructions
that convert a float to a double and then a double back to a float.
