For certain calculations involving armor, the `GetDamage` function needs to know if the damage is being applied by a beam so it can apply the calculations with the proper frametime. The parameter was not provided in all cases, so this fixes that.
Follow-up to #1609.
When a non-looping persistent sound expires, `obj_snd_stop()` actually does need to be called. Even though the sound is no longer playing, the `Num_obj_sounds_playing` tally needs to be decremented, otherwise it will eventually exceed its limit and prevent any additional persistent sounds from playing. And it turns out `obj_snd_stop()` returns gracefully for sounds that aren't playing.
Follow-up to #3510. Fixes a bug that appears to have been around since retail.
* fast version of setting position and orientation
* preliminary stale collide time
* add global collision cache stale flag instead
* clean up
* more clean up
* no periods >.>
* bring back single object version
* rename and bring back stale object list
* use a set
1. Add a function to retime *only* the collision pairs involving a specific object. This is useful when only one object has moved, since only collisions involving that object are affected.
2. Use this function when objects are moved for autopilot, via sexp, and via script.
Previously collision pairs were not retimed when objects were moved via script, leading to bugs. This fixes that.
Take into account the collision flag and collision groups when spawning a ship. Should fix#5357.
Also clean up the code a bit, including setting a few `int`s to `bool`s and adding a missing axis case.
This initializes `mc_info` to the correct values when it is constructed, removing the need for `mc_info_init`.
This PR also fixes a group of incorrectly inverted assignments in beam.cpp.
Follow-up to #5040. This extends the checks to most iterations over `obj_used_list` in FSO. There are a few exceptions such as `waypoint_add` and `waypoint_remove`, plus a few others. And none of the object iterations in FRED have the guard because FRED does not use the same object life cycle as FSO.
When iterating through various object collections, check for the should-be-dead flag to avoid returning objects that are on the verge of being deleted.
Separately, this adds the `isExpiring` function to check for should-be-dead objects.
This PR also makes object iteration consistent across all object types, both to reduce code duplication and to ensure that the length and iteration are done using the same algorithm. Furthermore, if the number of should-be-dead objects is nonzero, the Lua array count for that frame will be different from the internal array count for that frame.
Fixes#5034.
* Fixes CTD with decals on dying ships
If a ship was getting shot with weapons that used decals, the decal code would hit an assertation, because the invalid decals were not being all removed.
This PR updates the decal cleanup loop, to ensure that no decals are missed and all invalid ones are removed. Tests confirm this fixes the issue.
Also cleaned up some comments and moved another assertation before setting of variables.
* Exposes modder useful options to decals
Now that decals are very stable, this PR exposes two options that are very useful for using decals, a random range for the radius along with the option to have a random rotation when the decal is created.
Tested and everything works as expected.
* add script ability to toggle decals
* properly use set arg not func
* fix two minor things in decal shader
* one more cleanup line
* fixes
Adds gravity! Applies on a per-mission basis, and weapons, ships, debris, and asteroids now have a configurable "gravity const" which multiplies the effect of gravity on them, by default everything except debris is 0 (meaning no effect even when the mission has gravity). AI and the lead indicator will also lead for ballistic trajectories as well, given a gravity-affected weapon. No FRED support or gravity direction control yet, to come in later PRs.
Gather all the mission initialization code into a common function for clarity and ease of expansion. Previously, the various parsing routines contained initialization as well as parsing. As a bonus, quite a few redundant initializations are streamlined.
* Fix subsystem change handling code
Make sure that subsystem help actually gets updated.
* change from pointer to literal
I had decided to use `new` in the past when I was less experienced. So this changes it back to regular angle variables.
(And White space fix requested by Wookie)
The ship record for player ships is not always accurate. So as to correct entries as valid packets are received.
Also, remove a case where null vectors were being passed to the physics engine.

* Add deferred cockpit lighting
* Put deferred Cockpits behind a flag
* (hopefully) fix bad in-case initializer
* clear non base color buffer in subsequent deferred passes
* Proper deferred Cockpit rendering
* undo whitespace changes
Scripts that render models in the On Object Render hook were effectively doing immediate renders in the middle of queued renders. This caused some data, such as model orientation, to 'leak' between renders. It might also have something to do with why the bug in #4637 had the particular graphical side effects that it did.
Anyway, changing the immediate renders to queued renders fixes the leaky orientations, and is probably a good upgrade for other reasons as well.
Change Interpolation function to bool
And calculate last position instead of just setting it
This should help FSO prevent some very odd collision issues when two ships collide
`Ai_flag_names[]`, `Object_flag_names[]`, and `Ship_flag_names[]` all had an associated `#define` containing their length that had to manually be incremented whenever new flag names were added to the list. This commit instead makes the number of flags in the list be computed by simple `sizeof` division, so now adding a new entry just requires adding the entry, rather than remembering to bump a `#define`. Tested in FRED to make sure populating `OPF_SHIP_FLAG` entries still works.
Previously the persistent object sound management code would attenuate all script-assigned sounds by engine strength, and would not play them at all if the engine was off. This fixes the code to only apply that logic if the sound is in fact and engine sound.
This takes a few of the existing hooks and converts them to the new style of hook definition which can include more extensive documentation and enumeration of supported hook variables.
This is an updated version of #3151 to work with the latest codebase.
NOTE: Before this can be integrated into the codebase, it needs an implementation for `bool script_state::IsActiveAction(int hookId)` which apparently only has support for old-style script hooks.
