Admiral Nelson led me to discover that the HUD gauges expected "right" or no string at all for the gauge alignment. I added basic recognition of LEFT and RIGHT alignment. Someone more familiar with the HUD than me can flesh it out more.
This is a minor follow-up to PR #2390. There are a few minor differences between untranslated strings and the internal strings in strings.tbl; this PR fixes them.
This adds the following functions to the scripted gauge API: drawCircle, drawRect, and drawLine. Also note that I created an additional function, for HUDGauge:renderCircle_unfilled, becuase the precedent shown by having two functions for `gr_unfilled_circle` and `gr_circle` and adding a fourth argument to `renderCircle` seemed to affect a lot of other functions.
This commit adds new id for existing strings, so that they are translateable through the strings.tbl.
The following is translateable now:
- The 'or' seperator in the Keypress Directive gauge, if one function is bound to two keys.
- The Supernova warning.
- The error message that is displayed prior the pilot selection screen, if something is wrong with the loaded modification.
The new gauge can be accessed by the scripting API with which a function
can be set which will be called when this gauge is rendered. This can be
used for exposing the HUD gauge positioning and RTT options to the
scripting API without a lot of work needed for the script writer.
There is currently only one rendering function implemented since this is
only a proof of concept.
Currently, the player is unable to see a RTT hud gauge if in chase view. This adds an option in the hud_gauges.tbl that tells the game whether to draw a gauge based on if chase view is the active view. So for example, a modder using RTT mapped gauges can now make a HUD that displays on the interior of the ship (ie RTT with the cockpit model) and a HUD that displays when the player switches to chase view.
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 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.
While debugging a performance issue reported on Discord I noticed that
the HUD rendering code does not have any tracing scopes. This adds a few
tracing scopes to that code to make performance debugging a bit easier.
Previously, the hud gauge was hidden if the player ship had taken no
damage. However, this made it impossible to see if subsystems have been
damaged.
These changes make sure that the subsystem values are shown even if the
hull integrity is at 100%. This is done by first collecting all the
necessary information about each line in the gauge and then, if that list
is non-empty, rendering it. This is necessary since the gauge code can't
decide if anything will be visible before looking at the entire
subsystem list.
There is a minor behavior change with how popups are handled.
Previously, the code would return if the HUD gauge was a popup and its
strength was at 100%. However, I think that this was dead code anyway
since that condition could never be true at that point because the code
would have returned earlier if there was no damage.
This fixes Mantis 3183.
The codebase had quite a few instances of .size() being called and then checked to see if it was 0 or not (or less than 1, or greater-than-or-equal-to 1, which are basically equivalent), when .empty() could be called instead (negated or not, depending on what the original condition was).
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.

Converts Ship_info from a ship_info[] to an SCP_vector<ship_info>. ship_info now has proper constructors, assignment operators, and a destructor. Num_ship_classes removed; various references to Num_ship_classes and/or MAX_SHIP_CLASSES (which remains for various other structures which need it) changed to Ship_info.size() instead.
This doesn't make the ship class limit dynamic, but it is a preparatory step to get there.
