This is an actual edge case bug. If no countermeasure was set, and then one was set, there might be a garbage timestamp set that would give an incorrect countermeasure delay on next use.
A mission in Mantle caused an invalid vector access when checking whether to vaporize a ship whose ship type was -1. Turns out having "no type" is actually allowed, so I audited all `class_type` accesses throughout the code for potential -1 accesses. Most were properly checked but a few were not. A few others needed to be tweaked.
(I suspect this is something that would be on the Coverity list if it isn't already.)
Fixes#3098. The `shipfx_eye_in_shadow` function did a collision check for cockpits, bit did not previously take into account of the viewpoint had a non-forward orientation (ie the player was using free look). This PR sets the collide check to take that into account with a 1 line fix. Tested with multiple FotG cockpits and fixes the issue.
Add "tactical" versions of disable and disarm goals which only perform the specific task without implying anything else. The target ship is not protected and attack goals are not cleared from other ships.
There is also a new AI profiles flag to make this the default hud squad message command instead of the classic disable/disarm.
If a ship is in the process of dying, it shouldn't be killed or self-destructed again. This fixes a bug noticed by RedMageJoe during the Derelict playthrough.
(This situation is distinct from a ship being hit while in the middle of its death roll. That shortens the death roll but does not try to kill the ship again.)
Remove a whole bunch of ad-hoc code piled on top of the retail weapon cycling behavior, then replace it with a robust algorithm that takes all relevant attributes into account.
Fixes#5529.
Subsystem hitpoints are calculated as a percentage of the ship's hull strength as they are parsed. If a modular table modifies the ship's hull strength, the subsystems are not modified at the same time. This can lead to unreasonably large or small subsystem hitpoint values, as recently seen in the 1.3.0 version of Cardinal Spear.
This PR adds an option to defer hitpoint calculation until after parsing so that the subsystem is a percentage of the correct hull strength. Since this may affect the balance of existing mods, it is off by default unless the build targets 24.0 or later.
This also removes the long-unused `hull_percentage_of_hits` check and adds several log statements for significant options in game_settings.tbl.
The Star Fox barrel roll effect is achieved using a script which spawns a new ship. The script sets no-collide on this spawned ship, but it also tries to set the ship flag for all future ships -- and future ships require a parse object, which doesn't exist for a created ship. This patches the FALLTHROUGH in the sexp code to account for that possibility.
Separately, there are other ways a parse object pointer could become null through unusual code states, so this adds an INVALID status and several additional checks to defend against this crash in other circumstances.
The retail warp range multiplier can yield ridiculous results, like an Elysium warp being audible over 9000 meters away. So allow the multiplier to be set via ship type.
Adds a `DEATH_ROLL` status to specifically cover the state after ships have been destroyed but before they exit. I've also audited all code that interacts with the ship registry to use the correct state with this new state taken into consideration.
This fixes access to exploding ships that was broken when the ship registry framework was introduced. In particular, the `when destroyed X beam-lock-all X` QoL feature now works again.
If consecutive red-alert missions have different numbers of ships in a wing, then calculating the number of waves will not be correct. This necessitates the addition of wing status to the stored data for red-alert sequences.
Not only must wing data be stored in `Red_alert_wing_status`, but also in the CSG file. This necessitates a version bump. Fortunately, the current design of CSG files allows extra data to be added to a section without breaking old builds, since the CSG loader will just skip over the unrecognized data.
This also renames `red_alert_wingman_status` to `red_alert_ship_status` since it's not limited to wingmen, as well as fixing the omission of exited ships if they are in the player's wing but don't have the red-alert-carry flag.
Fixes#5637. Follow-up to #4457 and #5609.
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.
