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.

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.

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.
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.
- target-part
- ;; ERROR: Failed to convert to atomic ops: Variable could not be
constructed from register r0 in `process-drawable-shock-wall-effect`
- gun-part
- missing sparticle decompiling case it seems related to `L155`
This is pretty rough but...im excited to see it working :)
Almost done:
- `target-handler` (`(none)` event handler casts and CFG error)
- `target2` (`(none)` event handler casts)
- `powerups` (`cloud-track` does some weird stuff with `handle`s)
- `gun-states` (CFG error)
Some progress in:
- `water-flow`
Additionally:
- Clean up the two year old Jak 3 config file and add a config skeleton
(disassembling seems to not have worked, but I was able to dump obj
files and the `all_scripts` file)
- Fix automatic skelgroup detection and `defskelgroup` macro for Jak 2
(closes#1950)
- When a function decompiles without any major errors, a warning is
generated with the op id for each unresolved load and store that will
likely fail to compile (closes#1933)
Just missing `target-board-handler` because it errored with `Bad delay
slot in clean_up_cond_no_else_final` and I wasn't able to figure out
where the asm branch was.
Commented out `target-board-clone-anim` because it crashes even after
adding `clone-anim` and `clone-anim-once`.
