Hollow Knight in-game timer mod

To install the mod, grab the release ZIP from the latest 1.2.2.1 release. Extract all 3 .dll files into the Mods folder in your Hollow Knight installation.
The modding API will say that System.Runtime.Serialization.dll failed to load but this is completely normal

For current patches of the game, the timer is available from the "Scarab" mod manager

Like the 1.2.2.1 release, take the ZIP from the latest 1.0.2.8 version. Then follow the same steps for the 1.2.2.1 installation

The keybinds and various other settings can be edited in the hktimer.json in the same directory as your save files. They follow the unity keybind naming system.
the defaults are

{
    "pause": "[1]",
    "reset": "[0]",
    "open_ui": "f1",
    "set_start": "[7]",
    "set_end": "[8]",
    "timerPosition": {
        "x": 1880.0,
        "y": 1020.0
    }
}

Note that "[1]" means numpad 1.
See this image for a full list of acceptable inputs: Acceptable Inputs

The setting timerPosition can be used to change the position of the timer text. The point specified is the Middle-Right point of the main timer text rectangle. Values is the pixels of the screen from the lower left corner.

This mod comes with a badly programmed GUI that can be opened with the open_ui keybind. In the ui you can use the up/down keys to navigate, and the left/right keys to change the options, and the menu accept key to activate buttons (like "Save Triggers", "Reload Settings", etc)

Currently, you are able to place a start and an end trigger that can start and pause the timer respectively. They are marked by a green (start) or red (end) square floating in the air. Saving them (default keybind num6) creates a file hktimer_triggers.json in your save folder that contains the positions. You can copy this file to save different trigger presets. Loading the file (default keybind num9) will read that same file. This is done automatically on game start as well

The following trigger types are currently implemented

• Collision Trigger: the basic trigger that will activate when you walk into it
• Movement Trigger: a trigger that will activate when you do an action while you have control
  • Note that this trigger cannot be used as an end point
• Scene Trigger: a trigger that will activate when you enter the scene

The timer also shows a personal best that is tied to a set of waypoints. These are saved in hktimer_triggers.json and measured in microseconds (1000 per millisecond). The PB is loaded when you load the triggers, so if you need to edit/reset it just edit the file. The PB will be wiped when you change the trigger positioning, and has to be saved using the save triggers button.

TBD - Just look in the code or ask me on discord cause this format got fairly complex but luckily manual editing is no longer super required
