FSO doesn't appear to use this any longer. And even when it was enabled the
requirements made it largely useless anyway. Removing to clean up cfile a
bit and so we don't have to keep maintaining it.
* Fixup HUD for slewing
* Fix Training Message box
* Lead indicator slew
* Fix HUD Message Head
* Correctly render messages
* Fix HUD offset handling
* HUD offset never makes any sense
* Cleanup offset code
* Remove unused parameter
* Fix Talking Head in RTT mode
* add subfolder support to cfile
* sort files in VP archives before indexing them
* fix indexing of sub-subfolders
* remove unused 8B22K & 16B11K sound path types
* add more items to skip subfolder scanning
* fix windows build issues
* fix unit tests by allowing 0-byte files to be indexed
* fix file indexing on windows
* add test for cfile subfolders
* remove specific 'markup' and 'css' interface subfolders
They aren't directly referenced anywhere by pathtype and the new
subfolder code will continue to index and load files from them
* add player binds to list of always-root locations
* remove file-based localization support
An alternative is left in place for old fonts, as that was the only place
it appeared to be used.
This method of file localization conflicts with subfolder support however
so if it's needed in the future then changes to the subfolder code will
be necessary.
* add subfolder support to cf_find_file_location_ext()
* add subfolder tests for cf_find_file_location*()
* add shlwapi to needed win32 libs
* small bit of cleanup
* add subfolder support to cf_get_file_list()
* add tests for cfile subfolder lists
* report files that might be shadowed
* fix issue with lists when a filter is used
Also fixes discrepancy in older cf_get_file_list() when a sub path
is specified (should be used in all cases, not just glob).
* address review suggestions
Changes the `current_frame` checks in generic.cpp so that the last frame can actually be reached (allows the mainhall code to tell the misc animation has finished), and adds a `generic_anim_reset()` function that gets called instead of manually setting `current_frame` and `anim_time` to 0. This should fix#3399.
This adds access to the command briefing data parsed from the mission
file to the scripting API so it can be used by the UI scripts for the
high res UI.
Also switches the animation support to using the generic anim to use
streaming to improve performance.
The amount of output parameters is becoming quite large which makes it
harder to add new input parameters. For that reason I converted the
existing output parameters to a struct which cleans up the function
signature a lot.
This allows to use more complex file structures in the executable
without requiring that those exist as real files. The rest of the code
does not need to handle the difference between a default file and a real
file anymore which means that it's now possible to embed image files
into the executable since bmpman only needs to use the standard CFile
API.
I added two tests which check if the default file can be found and
opened and if a mod file overrides the default file which should always
be possible.
When streaming an ANI file, first anim_load() is called, then init_anim_instance(). The latter increments the animation's instance_count. If anim_free() is called on an animation that still has instances, it refuses to free the animation. generic_anim_unload() first called anim_free(), then free_anim_instance().
The fact that ANI files would ever unload at all seems to be because some code would unload twice. I can only assume that, combined with the fact that the bug only applies to ANI files, explains how this bug went undetected since November of 2009 (commit b43417882f seems to be when it was added, from a quick glance at git blame).
Prior to APNG support, a regular non-animated PNG could be used as a still-frame command briefing animation. This started causing a crash when APNG support was added because any PNGs sent through generic_anim_stream() would get ga->type set to BM_TYPE_PNG, then sent through the APNG code... which would determine that they weren't APNGs, throw an ApngException, and generic_anim_stream() would return -1... except that BM_TYPE_PNG would still be set, so that when it later came time to render the still frame in generic_frame_render(), it would be sent through generic_anim_render_variable_frame_delay()... which expected a fully-formed APNG, tried to dereference ga->png.anim, and crashed.
This commit is a simple fix to reset ga->type to BM_TYPE_NONE if APNG processing fails, allowing the still-frame PNG to go through generic_anim_render_fixed_frame_delay(), the code path it used to take, and allowing it to display properly instead of crashing.
Apaprently the alpha blend behavior has been broken for a long time and
alpha blending was always enabled. I changed the default lua opacity
type to match this behavior so that older scripts don't get broken by
this.
Choose that if a system is too slow to compose & render apngs fast
enough, play the anim until the last frame anyway, potentially messing
up time sync between frames, but at least don't have looped anims
stuttering as they skip back to the 1st frame from some non-end frame.
Most modern-ish systems won't see this issue unless there's lots of
apngs playing at the same time...
Main use case is headanis where only one is played at a time and
caching the frames merely increases memory use & fragmentation, leading
to malloc errors with heavy apng use
With png & apngs sharing the same filename these warnings could fire
quite a bit, and the lack of an anim playing should be very obvious to
the modder anyway.
Use unique_ptr for safer pointer management
Simplify frame delay calcs when looping
Ensure animated cursor times don't lose precision
Switch Error to an Assertion
Fix LUA documentation formatting
Handle total_time directly requested from bm_load_animation
Make generic_anims request total_time directly
Move png-vs-apng check to apng class
Remove redundancy in apng exception messages
Update comments
Fix silly issue preventing getFrame() from working
Remove infinite loop when calculating frame num
Convert more animations to use new frame calc function
i.e. apngs (pre)loaded into bmpman slots
handles apng variable frame delays
Includes new lua function (getFrames) to find the current frame for
apngs. Also uses new function to correctly display apngs for mission
loading animations, ship thrusters & engine glows.
includes:
full-colour & hud-colour headanis
cbanims & intelanims
mainhall animations (including playing in reverse)
Notably does not support ship/weapon select anims as they need
keyframes and there isn't anywhere to specify them in the apng format
As headani's (both ANI & EFF) are streamed there's no need to have
the anim data in bmpman, the streaming code does that with only two
slots, rather than one slot per ani frame
Also fix a "leak" in the streaming code use of bmpman slots. i.e. each
time a message was played another slot would be used & not released
