Update the Lua enums to be consistent with the new ShipStatus enums.
Separately, add an extra ship registry check in the event a ship doesn't exist in the ship registry.
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.
1. Allow setting the homing subsystem if the homing object has already been set
2. Use the `weapon_set_tracking_info` function if setting both object and subsystem, as it handles several important homing things
The `collides` and `no_collide` flags are equivalent, but opposite. So when sexps or scripts get or set those flags, allow each to be used as an anti-synonym (not exactly an antonym) for the other.
Since `gr_string` can accept a length parameter, there's no need to copy each line before it is drawn.
Related to #5495 but not one of the two options mentioned.
1. Add a `vanish()` function for beam objects, to be consistent with other object types
2. Add a `BeamFree` virtvar, analogous to `TurretLocked`
3. Add timestamp variants of TurretLocked and BeamFree to be consistent with sexps
4. Add `BeamLife`, `BeamWarmup`, and `BeamWarmdown` virtvars so scripts can access table properties
5. Add "On Beam Death", "On Beam Warmup", and "On Beam Warmdown" hooks
6. Clarify some existing documentation and patch a couple things
This adds several fixes to make the event and menu music more robust:
1. The game will now run with zero soundtracks. All accesses into a potentially empty vector should now have checks.
2. Soundtracks and menu music are now checked for validity before being played (not just when importing a FSM mission).
3. The parsing validity checks and the in-game event music now check for skippable patterns using the same function.
4. Zero measures and zero samples-per-measure now cause the game to skip a pattern. Negative values now trigger a warning.
5. Omitting some or all of the `$Name:` lines for a soundtrack will not cause an assert.
Fixes#5576. Follow-up to #5572.
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.
Since other functions in the scripting API remove extensions before loading the files, and since the internal functions expect them to be removed, the streaming anim API should handle that too.
* 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
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.
See title. There were some cascade effects, but the changes are mostly contained to the model code. The calls to `gr_render_model` and `g3_render_primitives` use `const_cast` because constifying that API would require a whole other PR.
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.
