Major change to how `deftype` shows up in our code:
- the decompiler will no longer emit the `offset-assert`,
`method-count-assert`, `size-assert` and `flag-assert` parameters. There
are extremely few cases where having this in the decompiled code is
helpful, as the types there come from `all-types` which already has
those parameters. This also doesn't break type consistency because:
- the asserts aren't compared.
- the first step of the test uses `all-types`, which has the asserts,
which will throw an error if they're bad.
- the decompiler won't emit the `heap-base` parameter unless necessary
now.
- the decompiler will try its hardest to turn a fixed-offset field into
an `overlay-at` field. It falls back to the old offset if all else
fails.
- `overlay-at` now supports field "dereferencing" to specify the offset
that's within a field that's a structure, e.g.:
```lisp
(deftype foobar (structure)
((vec vector :inline)
(flags int32 :overlay-at (-> vec w))
)
)
```
in this structure, the offset of `flags` will be 12 because that is the
final offset of `vec`'s `w` field within this structure.
- **removed ID from all method declarations.** IDs are only ever
automatically assigned now. Fixes#3068.
- added an `:overlay` parameter to method declarations, in order to
declare a new method that goes on top of a previously-defined method.
Syntax is `:overlay <method-name>`. Please do not ever use this.
- added `state-methods` list parameter. This lets you quickly specify a
list of states to be put in the method table. Same syntax as the
`states` list parameter. The decompiler will try to put as many states
in this as it can without messing with the method ID order.
Also changes `defmethod` to make the first type definition (before the
arguments) optional. The type can now be inferred from the first
argument. Fixes#3093.

This change adds a few new features:
- Decompiler automatically knows the type of `find-parent-method` use in
jak 1 and jak2 when used in a method or virtual state handler.
- Decompiler inserts a call to `call-parent-method` or
`find-parent-state`
- Removed most casts related to these functions
There are still a few minor issues around this:
- There are still some casts needed when using `post` methods, as `post`
is just a `function`, and needs a cast to `(function none)` or similar.
It didn't seem easy to change the type of `post`, so I'm not going to
worry about it for this PR. It only shows up in like 3 places in jak 2.
(and 0 in jak 1)
- If "call the handler if it's not #f" logic should probably be another
macro.
Fixes#805
This renames the method object in `defmethod`s to `this` and adds
detection for the `set-time!` and `time-elapsed?` macros.
Definitely my biggest PR yet...
- 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.

I think this is very likely to fix
https://github.com/open-goal/jak-project/issues/2970
We had somebody report a stacktrace from the debugger, and it was
immediately after calling `gen-perms`.
I found that `gen-perms` writes past the end of a stack array during
this mission, and at the same time as the reported freezes.
I was unable to recreate the original freeze after making this change.
Changes the DGO build order so that the city gets compiled first, and a
random guess at an "order" of which levels people might edit more often.
Most of the data-only borrow files are moved to the end as well.
Also moves around files in the `goal_src` tree to a structure that makes
a bit more sense, some files were either in the completely wrong place,
their folders had strange names, were too deep for no reason or were
just too far away from other relevant files. This structure should make
it easier to guess a file's location.
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.
Adds support for adding custom subtitles to Jak 2 audio. Comes with a
new editor for the new system and format. Compared to the Jak 1 system,
this is much simpler to make an editor for.
Comes with a few subtitles already made as an example.
Cutscenes are not officially supported but you can technically subtitle
those with editor, so please don't right now.
This new system supports multiple subtitles playing at once (even from a
single source!) and will smartly push the subtitles up if there's a
message already playing:
Unlike in Jak 1, it will not hide the bottom HUD when subtitles are
active:
Sadly this leaves us with not much space for the subtitle region (and
the subtitles are shrunk when the minimap is enabled) but when you have
guards and citizens talking all the time, hiding the HUD every time
anyone spoke would get really frustrating.
The subtitle speaker is also color-coded now, because I thought that
would be fun to do.
TODO:
- [x] proper cutscene support.
- [x] merge mode for cutscenes so we don't have to rewrite the script?

Gives proper names to almost every color. It is very apparent that some
colors are context-sensitive/made for a specific purpose, so those
colors were named after that purpose instead of a generic color name.
Also fixed an original game bug in `loader.gc` on a method that's called
quite often, though I have no clue what erroneous behavior it could have
even caused.
- elec gates now always render at max quality if you have PS2 lods
disabled. the original render distances are so low that the one in
caspad is impossible to see in normal gameplay.
- `fort-entry-gate-11` and `com-airlock-outer-13` are specifically
banned from the all actors hack because they are placed in a bad spot
and Naughty Dog did not program the airlocks very well.
- fixed NPC talk distance being bad for 1 frame.
- fix `sew-scare-grunt` erroneously keeping its spool anim active if you
killed the enemy.
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.
This fixes the issue where elevators leave you behind (stack structure
related)
At the same time I cleaned up some things I found along the way, most
notably changing `script-context`'s `basic` field to `object` as
non-basics use this method as well.
Fixes#2305
Adds the `pckernel` system to Jak 2, allowing you to do the PC-specific
things that Jak 1 lets you do like change game resolution, etc.
In other to reduce the amount of code duplication for something that
we're gonna be changing a lot over time, I split it into a few more code
files. In this new system, `pckernel-h.gc`, `pckernel-common.gc`
(previously `pckernel.gc`) and `pc-debug-common.gc` are the files that
should be shared across all games (I hacked the Jak 2 project to pull
these files from the Jak 1 folder), while `pckernel-impl.gc`,
`pckernel.gc` and `pc-debug-methods.gc` are their respective
game-specific counterparts that should be loaded after. I'm not fully
happy with this, I think it's slightly messy, but it cleanly separates
code that should be game-specific and not accidentally copied around and
code that should be the same for all games anyway.
Moves PC-specific entity and debug menu things to `entity-debug.gc` and
`default-menu-pc.gc` respectively and makes `(declare-file (debug))`
work as it should (no need to wrap the entire file in `(when
*debug-segment*` now!).
Also changes the DGO descriptor format so that it's less verbose. It
might break custom levels, but the format change is very simple so it
should not be difficult for anyone to update to the new format. Sadly,
you lose the completely useless ability to use DGO object names that
don't match the source file name. The horror!
I've also gone ahead and expanded the force envmap option to also force
the ripple effect to be active. I did not notice any performance or
visual drawbacks from this. Gets rid of some distracting LOD and some
water pools appearing super flat (and pitch back for dark eco).
Fixes#1424
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.
No more ghost town!
Manual patches:
- `hal3-course`: In `(anon-function 17 hal3-course)`, the decompiler is
doing something strange with `s3-0` that fails to compile, so I just
removed the `set!` and inlined the condition in the `when`.
- `guard`: Rewrote `(.mula.s)` stuff
