A minor bug in #6077 resulted in a crash loading campaigns on the multi ui.
The bug itself was not fatal, however it triggered a cascade of poor error
handling which led to a crash. A lot of these issues date back to retail.
This fixes the minor bug, and hopefully adds enough error handling to
preemptively squash a repeat of the crash problem.
1. Add an explicit `mn.createWaypointList` function
2. Allow `mn.createWaypoint` to be used with an empty waypoint list
3. Update documentation of `mn.createWaypoint` to clarify optional arguments
* lua access to the comm board menu
* On Order Issued Lua Hook
* Some cleanup and safety checks
* Add mn.sendBuiltinMessage and perform more cleanup
* Send the correct ship to the hook for Sender
* clang cleanup
* address feedback
* fix build errors introduced from upstream
* basic hook conditions
* properly link the condition and the oswpt struct
* some requested cleanup
* allow for sending custom built-in messages
* address more feedback
* more prefix
Improve skipmemymissionyo in several ways, based on RedMageJoe's recent experience:
1. Allow spaces to be accepted in the mission prompt
2. If the requested mission can't be found, just abort rather than restarting the entire campaign
3. Clarify that the prompt needs a filename and add a message if the mission can't be found
4. Improve handling of the .fs2 extension
5. Fix a bounds check in `popup_input`
Make `SCP_vector`, `SCP_list`, `SCP_set`, and `SCP_multiset` subclasses of their STL counterparts. This allows helper functions to be added to each, including the `contains()` function which is not available until C++20. (This has minor effects on other parts of the codebase that treated `SCP_` and `std::` as synonyms.) Since there is now a nontrivial amount of code that needs to be in a .cpp file, create vmallocator.cpp.
Note that `SCP_string` truncation has been refactored to use length rather than C-string size to be consistent with other `std::basic_string` functions.
Also, remove some enum class hashing code which is no longer necessary now that the codebase is at C++17.
Add "goal" as a type recognized by scripted sexps. Also add `mn.Goals` as a collection to complement `mn.Events` and move the goal type to goal.cpp and goal.h to match event.cpp and event.h. The new `mn.Goals` collection contains the same data as the existing `Objectives` collection in the briefing UI library, so the latter could be deprecated.
Looking through all places in the scripting API where `l_Object.Set()` is called, here is one where we might want to know about the object's breed.
(Normally we would return the result of `ade_set_object_with_breed()`, but the `testLineOfSight_internal()` function has multiple return arguments.)
Several locations in the code (notably `ai_info` and `waypoint_h`) previously stored pointers for waypoints and waypoint lists that need to be valid for more than one frame. Since both waypoint lists and waypoint paths may change size, resulting in vector reallocation, the information should be stored as indexes instead.
Fixes#6353.
This refactors the object_h struct to store objects as indexes rather than pointers. This is a prerequisite for making the collection of objects dynamic in the future. See also #6100.
Follow-up to #5800 and #5829.
To enforce type safety for arrival and departure locations, this converts them to enum classes. Various casts are added when appropriate to convert between the indexed and enum values.
This allows the skybox orientation and alpha to be accessed and changed through Lua virtvars, and also adds a sexp to change the alpha.
Unfortunately, changing the alpha has no perceptible effect on the skybox. This will need the attention of a graphics coder to figure out what might need updating.
Turn `Parse_names` into a vector and add SCP_string overloads of ship registry functions. Refactor calling code to use registry as appropriate. Remove an unused overload of `mission_parse_get_parse_object`.
* add extra ways to modify background elements in missions
This adds Lua API methods for getting suns and bitaps by index, as well as modifying their scale and position. This removes the need to completely add and remove a background element that only needs to be modified.
* big pruning of (int) casts
The `mn.createWeapon()` function takes an optional group ID for weapons that share lighting, but the internal `weapon_create_group_id()` function was never exposed to the API. This adds that.
When fireballs were made dynamic in 609ed4ed94, the `MAX_FIREBALLS` #define lost any relationship to the fireball collection. This removes it and also correctly specifies the size of the fireball collection.
This fixes a CTD when accessing items in `mn.Fireballs` via script.
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.
