Use a simpler, more robust, and more correct method of sharing the fire direction among beams: replicate the actual beam vector for all firing points. This further cleans up and simplifies the beam firing code and also clarifies some vector math.
Some of the `frand_range` calls were used for integer calculations, so we can use `Random::next` now.
This also reduces the number of C-style casts in the codebase.
A mission in Mantle caused an invalid vector access when checking whether to vaporize a ship whose ship type was -1. Turns out having "no type" is actually allowed, so I audited all `class_type` accesses throughout the code for potential -1 accesses. Most were properly checked but a few were not. A few others needed to be tweaked.
(I suspect this is something that would be on the Coverity list if it isn't already.)
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 initializes `mc_info` to the correct values when it is constructed, removing the need for `mc_info_init`.
This PR also fixes a group of incorrectly inverted assignments in beam.cpp.
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.
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.
* beam_add_light_small() is only ever used in one place which always passes a point. Calculating the point inside is removed as redundant and obfuscating.
* Repeated beam light width calculation moved to function
* Repeated beam light state validation moved to function
* Repeated beam light noise generation moved to function
* cleanup superfluous parameter
Removed useless light_ignore_objnum and affected_objnum lighting data, light_add_point_unique() subsequently removed as well, and cleaned up unused parameters.
* Scale distant combat related effects so they stay visible
- Effects scaled so that they always maintain a minimum pixel size
- Supports lasers, beams, all trails, muzzle flashes, and thrusters
- Disabled by default, but can be configured through the game_settings.tbl
* Added comments clarifying when min pixel size scaling happens.
* Convert some NULLs to nullptr to make CLANG happy
