Since "No subsystems found" and "Not all subsystems have a record in ships.tbl" are different warnings, they should have different flags. Follow-up to #4408.
The check to not show `-destroyed` submodels is within `model_replicate_submodel_instance`, and that was only called for moveable submodels in the lab. This PR runs it for all submodels now. Tested and fix works as expected.
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.
Mostly renaming of fields and functions, and moving some modelread sections into functions. This reorganization will put the code on a better footing for the model translation feature. No model translation code is included yet, and there should be no change in functionality.
There are a few related improvements here:
1) Add a new function for iterating over the submodel hierarchy
2) Add a counterpart to the `subobj_num` field so that a submodel can refer to its ship_info subsystem
3) Update `ship_model_replicate_submodels` to replicate all movable submodels, even the ones that aren't associated with subsystems
Fixes#3967
By anchoring a dockpoint to a submodel, the dockpoint will move when the submodel moves. Historically this has been done by inspecting the path associated with a dockpoint, but this method will not work if there is no path or no rotation mode specified. Here is an alternate method that allows the submodel to be specified explicitly through a dockpoint property.
Previous code allocated 4x bsp_data_size for alignment, whether it was
needed or not. Now it should allocate slightly more than 2x and only if
alignment is required.
1) Changes the submodel flags to use a flagset instead of several booleans
2) Adds `rotate_accel` to allow submodel rotation acceleration to be specified
Submodel acceleration can now be instant; dumb-rotating submodels always instantly accelerate (and have always done so)
This moves submodel rotation out of the AI pipeline and into object movement. With the exception of turret rotation (which remains in the AI code) this now allows all types of submodel rotation to happen in the same place. Many associated functions have also been cleaned up.
In addition to making the code cleaner and clearer, this will make it much easier for intrinsic rotations and new animations to be applied to non-ship objects, such as weapons.
1) Make sure the `PM_FLAG_HAS_INTRINSIC_ROTATE` flag is only set after submodels pass validation and checking
2) Maintain compatibility with old models that used `$look_at` with the submodel number instead of name
