Notable things: - This assert is hit when trying to save the pc-settings file, NYI https://github.com/open-goal/jak-project/blob/e630b506903d7f7028dff89702be7f586c2120e7/game/kernel/common/Symbol4.h#L14 so right now settings aren't persisted. But RPC defaults to on - The existing functions can probably be made generic based off the game version, but I didn't spend time refactoring them yet as they aren't really ready to be used in jak 2 yet (we have no screenshots for the levels for example)

This file contains new code that we need for the PC port of the game specifically.
|
|
It should be included as part of the game engine package (engine.cgo).
|
|
|
|
This file contains various types and functions to store PC-specific information
|
|
and also to communicate between the game (GOAL) and the operating system.
|
|
This way we can poll, change and display information about the system the game
|
|
is running on, such as:
|
|
- display devices and their settings, such as fullscreen, DPI, refresh rate, etc.
|
|
- audio devices and their settings, such as audio latency, channel number, etc.
|
|
- graphics devices and their settings, such as resolution, FPS, anisotropy, shaders, etc.
|
|
- input devices and their settings, such as controllers, keyboards, mice, etc.
|
|
- information about the game window (position, size)
|
|
- PC-specific goodies, enhancements, fixes and settings.
|
|
- whatever else.
|
|
|
|
If you do not want to include these PC things, you should exclude it from the build system.
