The game stores the last 3 frames of input (50ms of time at 60fps) and
often checks if a button was pressed within those 3 saved frames as a
condition.
When transitioning states, it often checks if some input was received
during the previous state (within those 3 frames) in order to quickly
transition out. A good example of this is when transitioning to
standing, it checks if you can jump this frame and if you had pressed X
recently, and if so, transition immediately to jump. This allows
transitions between states to feel more smooth/forgiving by letting you
jump at a later time when you are transitioning from falling->standing
than if you were only falling.
At 165fps the last 3 frames is only 18ms of time so the input windows
for these smooth transitions are almost 3x shorter.
This PR saves 15 input frames (enough to cover 50ms of time at 300fps)
for each controller and adds a (recently-pressed?) macro that checks all
15 frames. However, it only updates the necessary frames in history
based on the current frame rate. This way, 60fps continues to only check
against 3 input frames, 165fps checks against 9, 240fps checks against
12, and 300fps checks all 15.

Adds the opengoal cheats to the secrets menu. Only cheats that are fully
functional and unlockable are there right now, which is eight cheats.
This update will reset most Jak 2 settings.
Also fixes#3274 .
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 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...
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.
This is a major deviation from the original game, which did not have any
way to access the nest after beating Metal Kor as the air train gets
hidden when he is beaten. This was mostly annoying because there are
precursor orbs in that level that you might miss.
This makes it so the air train can once again be used to enter the nest
even after beating Metal Kor. The rest of the level remains mostly the
same, except the Rift Ring does not spawn and an invisible wall is added
to the Metal Kor arena to prevent you from entering it as you are
normally unable to leave it anyway.
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.
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
Adding support for better child-type method docstrings. This is a
problem unique to methods.
Usually, a child-type will have the same signature and a common name
will apply, but the implementation is different. This means, you
probably want a different docstring to describe what is happening.
Currently this is possible to do via `:replace`. The problem with
replace is two fold:
- a replaced method ends up in the generated `deftype`...because you
usually change the signature!
- we don't put docstrings in the `deftype` in normal GOAL, this is just
something we do for the `all-types` file (they go in the `defmethod`
instead)
- more importantly, this means anytime you now want to change the
parent's name/args/return type -- you have to apply that change
everywhere.
So this is a better design you can now just declare the method like so:
```clj
(:override-doc "my new docstring" <method_id>)
```
And internally a pseudo-replaced method will be added, but it will
inherit everything from the parent (except the docstring of course)
Unrelated - I also made all the keyword args for declaring methods not
depend on ordering
This also adds support for documenting virtual and non-virtual state
handlers. For example:
```clj
(:states
(part-tester-idle (:event "test") symbol))
```
or
```clj
(idle () _type_ :state (:event "test") 20)
```
I will probably add the ability to give some sort of over-view docstring
at a later date.

- 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.
The VU programs for the ocean renderer have changed a bit and
`ocean-texture` has a bunch of new stuff, otherwise things are
relatively similar to Jak 1.
This is the first time I used mips2c and I'm not sure I did it 100%
right, so that should be double-checked.
The only interesting one is `collide-hash`, which is untested.
The other two are very likely unused. I skipped the annoying code in
`collide-probe` because it's not used and the same as jak 1.
And everything else needed for them!
A couple functions are bad currently.
- fixes#1929 - untested on linux
- fixes#1924 - now you need to type `,` before a lambda you want to put
in a pair.
- fix debugger symbol table in jak 2
- made the decompiler output `(meters 2)` instead of `(meters 2.0)`
- fixed a bug with the bitfield enum special -1 case
- made bad game text decomp not exit the decompiler
- added `editable-player` and `script`
eg
```
(set! (-> obj sound-pre-open) (static-sound-spec "airlock-slider"))
```
it is the same as jak 1, but the `fo-curve` option is set to 1
sometimes.
