- state handlers that are not inlined lambdas have smarter type
checking, getting rid of 99.9% of the casts emitted (they were not
useful)
- art groups were not being properly linked to their "master" groups.
- `max` in `ja` in Jak 2 was not being detected.
Another huge PR...
Previously, `object` and `none` were both top-level types. This made
decompilation rather messy as they have no LCA and resulted in a lot of
variables coming out as type `none` which is very very wrong and
additionally there were plenty of casts to `object`. This changes it so
`none` becomes a child of `object` (it is still represented by
`NullType` which remains unusable in compilation).
This change makes `object` the sole top-level type, and the type that
can represent *any* GOAL object. I believe this matches the original
GOAL built-in type structure. A function that has a return type of
`object` can now return an integer or a `none` at the same time.
However, keep in mind that the return value of `(none)` is still
undefined, just as before. This also makes a cast to `object`
meaningless in 90% of the situations it showed up in (as every single
thing is already an `object`) and the decompiler will no longer emit
them. Casts to `none` are also reduced. Yay!
Additionally, state handlers also don't get the final `(none)` printed
out anymore. The return type of a state handler is completely
meaningless outside the event handler (which is return type `object`
anyway) so there are no limitations on what the last form needs to be. I
did this instead of making them return `object` to trick the decompiler
into not trying to output a variable to be used as a return value
(internally, in the decompiler they still have return type `none`, but
they have `object` elsewhere).
Fixes#1703Fixes#830Fixes#928
This PR adds detection of the `launch-particles` and `seconds-per-frame`
macros to the decompiler, removing a lot of bloat and hiding many
process register uses.
I also added `og:preserve-this` comments to as many manual patches and
comments as I could, which will soon be used in conjunction with CI to
hopefully catch any regressions in future big decomp update PRs.
I have some concerns about the `launch-particles` macro (more details in
`sparticle-launcher.gc`) , but thus far, I have not seen anything break
yet.

Fixes empty boxed arrays of strings breaking some decomp
(`ctywide-speech` and `race-info`).
Adds `decomp-as` tag to decompiler types so that the static data
decompiler can use macros like `meters` and `seconds` on fields that
aren't of type `meters` or `time-frame`.
Adds `override` tag to decompiler types which overrides the type of
field with that name. The type must be a child type of the original
field's type (or the same type, but why would you do this?).
Fixes the camera being offset for `drillmtn` after loading `palout`
once.
This is a huge refactor sadly.
Updates the decompiler for the new format and there's new macros. This
new format should be easier to read/parse.
Also rewrote `sp-init-fields!` (both jak 1 and 2) from assembly to GOAL.
Hopefully I did not miss any regressions in Jak 1/2 while updating the
files, it's a lot.
There are *a lot* of file changes and while I have carefully gone
through every gsrc change to fix up manual patches, there might still be
spots that I missed.
Manual patches:
- `drill-turret`: The static data for `*turret-13-path*`,
`*turret-14-path*` and `*turret-15-path*` was decompiled by hand and the
integers in the `set-speed-mult` events have been replaced with boxed
integer arrays that contain only that integer in order to make the
compiler happy. To that effect, the event handler in `target-turret` was
changed to access that array instead of just accessing the int.
- `hover-nav-control`: In `hover-nav-control::10`, `arg2` is usually a
`vector`, but there are some places where it is called with `#t` as
`arg2` and, subsequently, crashes the game because it tries to access
the `quad` of `arg2` if `arg2` is truthy. To mitigate this, the
condition `arg2` has been replaced with `(and (!= arg2 #t) arg2)` (in
this case, it would jump to the `else` that just resets the `dest-vel`
and `transv` `quad`s)
- `drill-baron`: The static data for `*drill-ship-turret-speed-event*`
has been decompiled by hand.
TODOs:
- Jellyfish crash the game
- Destroying the metalhead eggs that are on the breakable wall crashes
the game (already happened with the Peacemaker before)
- Figure out why static data of type `turret-path-event` doesn't
decompile
The docs for all the hover-nav and nav-network code could use some love
in the future, I'm not smart enough to figure out what any of that code
actually means, but it seems to work...
Also threw in the fix for the ▲ that was accidentally left commented
out.
- started documenting the files I glossed over, some are totally done,
others are just partially done
- I changed the decompiler to automatically initialize the
art-group-info from the json file. This makes updating gsrc, even a
single file at a time, have consistent naming
- Though I disabled this functionality for jak 1, as I have no idea if
using the ntsc art groups will cause a regression for different versions
- fix indentation for docstrings -- it still doesn't look great, but
this is now a formatting concern, rather than the docstring having a
bunch of happen-stance leading whitespace.
I did some manual modifications in a few places to work around some
truly mysterious control flow, and some unsupported stack array stuff.
Also fixes a bug in decompiling static improper lists.
As far as I can tell, guns work, other than some graphical issues and
the crazy particle spawning issue, but I strongly suspect these are
problems with the sparticle/graphics side.
