This option was misleadingly named when originally introduced, so give it a more sensible name. The old name is still accepted for backwards compatibility.
Here's some low-hanging fruit for reducing the memory footprint of `ship_info`. This turns the maneuvering thrusters array into a vector, refactors the names a bit, fixes thruster activation when `-nosound` is active, reduces the number of calls to `ship_get_thruster_status`, adds some const-correctness, and converts the timestamps to the new system.
In many calls to `ship_get_subsystem_strength`, the caller doesn't care about the actual number, just whether the subsystem type is destroyed. So this adds an optimization to check specifically for that. In the case of `SUBSYSTEM_ENGINE`, this avoids an iteration over every subsystem on the ship which, for a ship with many turrets, can be significant.
Some of the `frand_range` calls were used for integer calculations, so we can use `Random::next` now.
This also reduces the number of C-style casts in the codebase.
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.)
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.
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.
