According to EatThePath's frame profiling, this one ship name lookup takes 2% of the frame time. It can be easily optimized by making use of the ship registry.
* Auto Truncate default ship names
Previously, placing a ship that had a long class name might create a default name that was too long and thus trigger a buffer overflow assert.
Such behavior was confusing if someone was just placing things in FRED and not sure at all what happened or how to fix it.
This PR replaces the assert with code to auto truncate the ship class part of the name to ensure that the default name will fit into the designated size.
* change var name
Floating-point comparisons are tricky beasts. See this article for a good summary of the issues involved:
https://randomascii.wordpress.com/2012/02/25/comparing-floating-point-numbers-2012-edition/
This PR improves support somewhat, although there are obviously situations in the code (such as comparisons to 0) that should still be addressed. This PR makes the following improvements:
1) Tightens the threshold on `IS_VEC_NULL` and `IS_VEC_NULL_SQ_SAFE` from 1e-16 and 1e-36 to FLT_EPSILON
2) Tightens the threshold for parsing `turn_time` in POFs
3) Restores the previous implementation of `fl_equal`
4) Adds a dedicated `IS_MOI_VEC_NULL` for moment of inertia values
5) Improves documentation
Follow-up to #4535 and #4443.
Splits the existing On Death hook into independent hooks for each relevant type. Adds On Ship Death, On Missile Death, etc. Also adds On Missile Death Started to complement On Ship Death Started.
* Add Animation Instance Flags
* Add SEXP barebones
* Unify and simplify animation parsing
* Clean up animation calling and use new animationlist api
* Add missing break
`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.
* more cleanup in preparation for model translation
1) Clean up stepped rotation, fixing some logic, adding safeguards for invalid values, and allowing rotations to go in the opposite direction
2) Add more specific SEXP error checking for AWACS and rotating subsystems
3) Assorted refactoring and polishing
* address feedback, plus a bit of extra cleanup
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.
* Fix AI Goal Display Strings
Okay so previously, if a target goal was not valid the code was
`strcpy(outbuf, XSTR("no orders", 495)); `
but then it was changed to
`outbuf += XSTR("no orders", 495);`
So it would instead append the "no orders" instead of properly replace the whole string. Looks just like a copy and paster oversight, since all the other text appends the name of the target with the order.
This PR correctly replaces, rather than appends that text. Fixes#4345
* appease clang
* use more simple =
While it may seem counterintuitive, we have to keep the standalone bogus ship from being added to the ship list so that we don't have to exclude it from all the places it could cause crashes or mysterious AI behaviors. Both were being observed, and this should fix them.
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.
* add subsystem indexer and ensure that ship_get_indexed_subsys and ship_get_first_subsys are independent
* also add reverse lookup from subsys to index
* update indexer to accommodate subsystem pointers being changed
* use clearer function names, and fix the type of subsys_list_indexer
* add assertions
* address latest feedbcak
Players are still affected by collisions locally, but other ships will literally pass through each other until updated by the server. A timestamp controls the frequency of collisions with the player ship.
* Add Subsystem Flag to Hide Turrets from Ship Loadout Stats
The statistics summary window in the ship loadout editor shows various aspects and stats of the selected ship. These can be toggled and customized through the ships table, but one line is actually autogenerated, `+Turrets`. This is unideal for certain ships, especially those which use turrets on ships in non-standard ways (for example having an AI controlled turret which shoots bombs). In these cases, the turrets are not actual turrets, and it is confusing for players seeing that there is a turret on the ship in the loadout editor. (I can give more detailed examples using FotG if needed).
This PR adds a subsystem flag which allows the modders to hide a turret subsystem so it is not counted in the auto generation of the `Turrets` summary line. (As a slight cleanup I also removed cleaned up the whitespace formatting on a nearby, but unrelated line).
* sync names
* fix renaming
For script hooks which use conditions, be more consistent about evaluating both objects involved, as well as evaluating the different types of objects.
Fixes#3874.
For some reason, ship flag parsing was still using a fixed-size array instead of a vector, limiting it to 20 flags parsed in a single entry. Since there wasn't really a reason to do that (it was basically parsing to a vector anyway, then resizing it down to the limit, then stuffing the C-strings into the array), I changed it to a vector.
`ship_set_default_weapons()` (which is called by `ship_create()`) was only setting `swp->primary_bank_capacity` for a bank if the default weapon for that bank was ballistic; if the ship was then equipped with an ammo-using primary and the `set-primary-ammo` SEXP was used on it, it would think the bank had a capacity of zero, resulting in 0 ammo.
This commit simply moves the assignment outside of the conditional, so that primary bank capacities are always recorded in the `ship_weapon` class.
* Fix Texture Replace with Ship Changes
Tabled `$Texture Replace` did not work on ships where the class is changed in the loadout or with the `change-ship-class` sexp. This was because the replacement textures only were loaded during mission parse, and the `change_ship_type` did not account for loading new textures from ship classes that were not in the initial mission parse. Part of the bug was also that the code that updates texture replacements was after the texture page-in section of `change_ship_type`.
This PR fixes that bug by properly loading the textures in when the ship class changes. It also moves the code to within the `ship_model_change` function (which is only used in the `change_ship_type` function) so that the texture loading happens correctly before texture page in.
* fix accidental whitespace changes
* fix comment
* also fix team colors
* comment spelling fix
* appease clang
* properly clear replace textures between ship changes
