This allows to render screen space decals into the deferred lighting
buffers no matter how complex the underlying geometry is.
Currently there is only limited support for using this in the engine.
Only weapon impact decals are supported at the moment for testing
purposes.
This adds support for specifying multiple sounds for a single game sound
entry. The engine then selects which sound will be played based on the
strategy provided by the game data. This required a few changes to some
of the game code since previously every game sound had exactly one sound
file attached to it. The most notable change is that it is no longer
possible to determine the exact duration a sound can have so instead the
new code computes the maximum duration a sound can have and uses that
where appropriate.
This also adds support for randomizing the pitch and volume of the sound
to provide a more varied experience even if only a single sound is used.
One possible issue that exists is that the "sequential" strategy only
works globally at the moment so if two sources use the same game sound
concurrently then the two sources will share the sequence of sounds
since there is no sound instance data at the moment. That can be added
in a future change but should not present a huge issue for most
use-cases.
Visual Studio on Appveyor somehow causes deprecation error on _our_
definition of vsprintf. I have no idea why these changes introduced this
warning but I won't debug Visual Studio compiler bugs that I can't
reproduce with my Visual Studio version so I just disabled those
warnings.
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.
Adds a new "+Pulse Interval:" countermeasure field that enables the new behavior; all countermeasures that don't have this field defined still use the old behavior of the global frame counter.
This changes countermeasure logic quite a bit, but I attempted to mitigate performance implications by re-using an existing traversal of the object list in order to build the list of active countermeasures each frame. If any countermeasures are actively pulsing in a frame, the object list is traversed again, looking for homing weapons. Each homing weapon then goes through the active countermeasure list and checks to see if it got decoyed. Most of this central logic is unchanged from the old behavior, although no longer separated into two functions, and it should be more efficient since it's using a prepared list of active countermeasures instead of traversing the object list looking for countermeasures for every homing missile (which are themselves found by traversing the object list).
I found this issue while debugging the JAD gauntlet where a script calls
getSignature() on an invalid object. However, object_h does not see the
object as invalid even though its signature is 0 which is defined to be
an invalid sigature. This should fix that by making sure that
object_h::isValid returns false if the saved signature is not valid.
This regression was introduced with the new model draw list which separates
collecting the drawing information and actually drawing the objects.
Previously, the scripting hook was always executed and the override
condition was used to determine if the normal rendering should happen.
Since 3.7.4, the scripting code is only executed if the condition was
overridden by Lua and if that override is active then the model isn't
rendered at all.
This executes the scripting hook in all cases and then checks if the
scripting system specified if rendering of that object should be
skipped. This introduces some slight changes in behavior since, when the
scripting hook is executed, the object isn't actually being rendered but
instead it's added to the draw list. IMO, that is not a major issue for
any existing application or else we would have heard about that until
now.
This fixes Mantis 3175.
If there was only one object and that got deleted the code that keeps
track of the highest object index would cause a negativ array index. I
added a check to make sure that the index was positive but that still
means that Highest_object_index will be negativ after that function
returns. I looked at the usages of the value and that value seems to be
fine with that code so I think this should be safe.
It was previously thought that dock_undock_all() was supposed to be within ship_cleanup() and was safe to do so. Nope.
dock_evaluate_all_docked_objects makes the assumption that the dock_list is still valid, so if the function called by it happens to nuke the dock_list (like with ship_cleanup) then it'll work with invalid pointer values.
A conditional originally added to shield_add_strength() to make shields not recharge beyond the recharge limit forgot to check that the amount shields are changing by was positive (unlike a couple other conditionals added/modified around the same time), so a call to shield_add_strength() with a negative delta (e.g. when transferring energy from shields to weapons) when the current shield strength is at or above the recharge limit (i.e. full strength when a recharge limit isn't specified) would immediately return without doing anything. This would, of course, result in no change to shield strength... so if you had full shields and had drained your weapon batteries dry, you could get free energy by hitting the button to transfer energy from your shields.
* Adds a warning for debug users when an unknown ship_state is passed to red_alert_delete.
* Removes commented-out code
* Doxy's ship_cleanup()
*Conform to each file's style.
*Extend ship_cleanup to better handle red-alert deletion.
*Also treat cleanup_mode as a flagset, instead of an enum as it was previously.
*Use existing methods to determine dock status and find the head of the dock list.
*Fixes a derp with dock_dead_undock_all()
*Doccument some docking methods in object.h
*Address requested changes.
The new design is centered around the Event Trace JSON format but it
should still be possible to adapt it for other profiling tools. The old
profiling system has been removed.
I'm not entirely sure if this is the correct way to do the computation
but I see no other way of fixing it but since the zero vector is a valid
value for the relative velocity this seems to be the most sensible
solution.
Also, related to this I found out that FSO causes a lot of NaN errors at
runtime which may need to be investigated at some point to make sure
they don't cause issues like this bug.
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).
