* Add drop shadows to HUD text
* Add drop shadow to reticle
* Add control to toggle Drop Shadows
* Double render reticle shadows
* Use gauge_color instead of creating a temp var
* Add shadows to ETS gauges
* Set shadow default to false and adjust formatting
* Restore numbering for controlsconfig
* Move colors up one level and generalize
* Initialize this first
* These are common to both all Briefings, so put them in the general Briefing category
Protects `Fiction_viewer_active_stage` if it reads a stage of -1 (it would have thrown a vector access error because the index is out of range). Also, given a lot of other scripting functions have additional built in error checks, I just added those to the fiction viewer functions.
* Allow `test_line_of_sight` to return intersecting object signature
The `test_line_of_sight` can currently provide the closest intersecting distance, but it would be very useful, especially for AI scripting, if this function could also return the signature of the intersecting object. This PR adds that functionality.
Tested and works as expected. Happy to discuss strategies for changing implementation, too. The extra, third return value for object signature was added to `getLineOfSightFirstIntersect` function because that function already returns 2 values. Thus, it will remain compatible with older scripts which only save the first 2 returned values.
* fix documentation
* fix typo
* return object instead of sig
* fix pointer
* use pointer pointer for full fix
* name clarification
Allow the variables controlling ship shudder to be independently set using scripting. Also add new flags to apply the shudder without decay and apply the shudder regardless of camera.
Also change the shudder timestamp to the new style.
* Add Animation Instance Flags
* Add SEXP barebones
* Unify and simplify animation parsing
* Clean up animation calling and use new animationlist api
* Add missing break
* Add Lua access to a ship's Scan Time
* Disallow writing to the shipclass value
* Remove ship access in favor of shipclass access. Resolve read only issue.
* Cleanup and error if script attempts to set Scan Time
* Whoops. Still need to get the shipclass.
In #4443, `fl_near_zero` was set to use default epsilon values in the `IS_VEC_NULL` check. In this comparison, epsilon is the wrong threshold because it used to have a much smaller threshold. The fix restores the previous definitions of `IS_VEC_NULL` and `IS_VEC_NULL_SQ_SAFE` by exposing the epsilon value as an optional parameter (similar to how `IS_NEAR_ZERO` used to work. This PR also restores `IS_VEC_NULL_SQ_SAFE` where it was replaced by `IS_VEC_NULL.`
* 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.
The movie player code was missing some important functionality, in particular:
1) There was only one timing method to get real-time elapsed time, which was not suitable for pausing or time compression
2) There was an improper cast for the FPS property, causing a script error
3) The `getSeconds` method lost precision during casting
This patches those deficiencies.
There's no need to keep all this infrastructure to run every frame for a barely used situation. This cleans it up a bit and does the position reset in the actual drawString function.
The two `VIRTVAR`s for Orientation in subsystems and submodel instances do the same thing, but did not have the same code - in particular, the subsystem version did not update the subsystem angle and turret angle. This syncs them up.
