* Add driven animation sets to weapons and cockpits
* enumify objnums
The general expectation is that model filenames can be specified as 'none' or '<none>' for no model, but as discovered by no tea, this was not consistent across the code base. For example, `$Model File: none` was handled as expected but `$External Model File: none` was not. This PR makes the handling consistent for all ship, weapon, and shockwave POF files, and also adds some extra checks when models are loaded.
In consultation with @BMagnu, code that validates data in the POF file itself should happen in `read_model_file_no_subsys`, as virtual POFs rely on their source files having correct data. I've added comments and slightly rearranged things to make this clearer, and also moved the new code from `read_and_process_model_file`. Additionally, I fixed two bugs by changing `parent > pm->n_models` to `parent >= pm->n_models` and adding a newline to the `nprintf`.
1. make `check_ok_to_fire` return a boolean (like `check_los`)
2. make `check_ok_to_fire` and `check_los` both use a position argument since we don't need the whole turret
3. remove the redundant position prediction code from `ship_get_global_turret_gun_info` (since that needs to be a "pure" function) while making sure "share fire direction" still works
4. skip calculation of the vector in `ship_get_global_turret_gun_info` if we don't need it
5. move the position prediction code out of `aifft_rotate_turret` and into its own function
6. prune some gun position calculation calls since in most cases one will suffice
7. fix position "jitter" with weapon subsystem damage in missions that use gravity
8. `model_rotate_gun` now uses a nullptr position for a reset instead of an extra boolean argument
9. use a more efficient method to calculate gun barrel length
10. a couple variable name changes for clarity
* Add global to local for matrices
* Add lua integration
* Get Submodel from Submodel instance
* Add submodel functions
* Add model instance from submodel instance
* Fix index
* Fix copy paste error
In #4702 this log line was changed to the 'Model' category, which made it hidden by default. This was missed in review but should be restored as it is a fairly important line.
Fixes#5507.
Modelread.cpp supports POF versions as low as 1900, but early model versions were not loaded properly because they relied on preprocessor directives rather than version checks. This changes the POF loading to correctly check version numbers and chunk IDs.
Fixes crashes when attempting to load a FS1 model.
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.
* validate chunk size to avoid align crash and add align skip flag
* change type from uint to int
* change mprintf output to a warning
* revert uint to int change and requested changes
* Init Particle shaders only if they're actually used
* set layout correctly
* Don't compile shadow shader if not needed
* Properly deal with capabilities
* Fix typo
* remove obsolete capability
* Enable clients to move turrets
This allows clients to user server data to move turrets according to the timing and target data on the server. Uses a small packet to do so.
* Update `$POF file Techroom:` Usage
Currently `$POF file Techroom:` is only used in the weapons loadout screen (despite having techroom in the name). This PR expands the use of the `$POF file Techroom:` to shiploadout select and the actual techroom.
If it is desired I can put it behind a game settings flag, but IMO it would make the most sense for modders to have this just work as the actual name implies.
* clean up code with feedback
* typo fix in comment
Floating-point comparisons are tricky beasts. See this article for a good summary of the issues involved:
https://randomascii.wordpress.com/2012/02/25/comparing-floating-point-numbers-2012-edition/
This PR improves support somewhat, although there are obviously situations in the code (such as comparisons to 0) that should still be addressed. This PR makes the following improvements:
1) Tightens the threshold on `IS_VEC_NULL` and `IS_VEC_NULL_SQ_SAFE` from 1e-16 and 1e-36 to FLT_EPSILON
2) Tightens the threshold for parsing `turn_time` in POFs
3) Restores the previous implementation of `fl_equal`
4) Adds a dedicated `IS_MOI_VEC_NULL` for moment of inertia values
5) Improves documentation
Follow-up to #4535 and #4443.
As part of the cleanup in preparation for model translation, there was a bit of code review that was actually incorrect. The calculation of the current step needs to be rounded down, because the step isn't actually complete until it fully reaches the next number. Rounding the step causes the submodel to jump around in all sorts of weird ways.
Follow-up to #4443.
* Add Animation Instance Flags
* Add SEXP barebones
* Unify and simplify animation parsing
* Clean up animation calling and use new animationlist api
* Add missing break
