Adds the standard Lua extension library for bit operations in Lua 5.1.
http://bitop.luajit.org/
Note that this library is normally called "bit", but it is added here as "luabit" because there is already a FSO scripting library called "bit".
* Add callback for user specified availability status
* Add target restrict hook
* Fix Restrict hook and add not self restrict type
* Fix documentation
* Fix typo
* scope the ai achievability enum
* fix scoped achievabiliy
1) Remove the extra branch in `check_ok_to_fire` that was added in SVN revision 10392, or commit 0d54630e83. If there was an actual Coverity error, this does not fix it at the proper location. More importantly, this breaks certain turret firing behavior.
2) Fix a couple of bounds checks.
3) Remove an incorrect stale comment.
This fixes the broken turret swarm weapons that were uncovered by the fixes in #2959.
1) In commit 770fce8de5, a flag was incorrectly ported from a bit to a flagset, which caused ships not in the tech db to not be removed.
2) Perhaps due to the pilot file upgrade, campaigns which had their tech databases reset would immediately load stale techroom data from the savefile. This change writes the savefile after the reset so that subsequent reloads will load the correct data.
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.
* Fix RTT Cockpits Gauges with Change Ship Class
Previously, using the `change-ship-class` sexp or scripting function did not update RTT cockpit gauges. This PR adds the cockpit code update functions to fix the issue. Tested and works as expected.
* comment consistency
* Implemented ship.checkVisibility for luaAPI, sharing logic with sexp isVisible. Made new function for the shared functionality
* Fixed a viewer-viewed mixup
It's theoretically possible for `parent_type` to get out of sync with the parent's type, particularly if the parent is destroyed. Since the field is almost never used, it can be removed.
Should fix#4105.
Allow scripts to reference submodels, submodel instances, and model instances. Currently just a few properties (like Orientation and Radius) can be accessed, but this can be easily expanded in the future.
Also add relevant functions to calculate real-world positions and orientations of rotated submodels.
Consolidated these functions and replaced the `find_submodel_point_*` functions with their closest `world_find_` counterparts. (One of those functions may not have actually worked correctly.) Also use the correct coordinate logic when returning normals from collision info in scripting.
Related to #3985 although not yet a fix for it.
