LethalCompany InputUtils

Utilities for creating InputActions and having them be accessible in-game. InputActions created through this mod are accessible in-game via the keybinds menu added in update v45.

For feature requests or issues head over to my repo

General Users

This mod is just a dependency for other mods, it doesn't add content, but it allows mods to add keybinds.

Where are my bind overrides stored?

Depends on the version of InputUtils:

• >= 0.7.0 Global: AppData/LocalLow/ZeekerssRBLX/Lethal Company/InputUtils/controls Local: BepInEx/config/controls
• >= 0.4.1 BepInEx/config/controls
• <= 0.4.0 BepInEx/controls

Recommended Install

Use a Mod manager. I won't provide support if a mod manager wasn't used, a mod manager makes it far easier to debug issues since users can just share a modpack code.

Developer Quick-Start

This Api/Mod is still in beta, please keep in mind that stuff may change. Feedback is appreciated.

Add the nuget package to your project, if you want a copy and paste solution:

add this to your project .csproj

<ItemGroup>
  <!-- Make sure the 'Version="..."' is set to the latest version -->
  <PackageReference Include="Rune580.Mods.LethalCompany.InputUtils" Version="0.7.3" />
</ItemGroup>

That should be all you need to get started.

Otherwise if you don't want to use nuget, you can download the latest release from either the Thunderstore or the Releases. Extract the zip and add a reference to the dll file of the mod in Visual Studio or Rider.

Initializing Your Binds

• Create a subclass of LcInputActions
  • An instance of this class will contain all InputActions your mod wishes to bind inputs for
  • Name the class appropriately
• Create InputActions using Attributes and/or at Runtime

public class MyExampleInputClass : LcInputActions 
{
    [InputAction("<Keyboard>/g", Name = "Explode")]
    public InputAction ExplodeKey { get; set; }
    [InputAction("<Keyboard>/h", Name = "Another")]
    public InputAction AnotherKey { get; set; }
}

Using Attributes

• Create instance properties for all desired InputActions
• Annotate the instance properties with the [InputAction(...)] annotation

[!IMPORTANT]
For actions to be registered to the API, Properties MUST be annotated with [InputAction(...)]

[InputAction("YourkbmPath", Name = "", GamepadPath = "", KbmInteractions = "", GamepadInteractions = "", ActionID = "", ActionType = InputActionType...)]

Required Parameters

• kbmPath: The default bind for Keyboard and Mouse devices

Optional Parameters

• Name: The Displayed text in the game keybinds menu

• GamepadPath: The default bind for Gamepad devices

• KbmInteractions: Sets the interactions of the kbm binding. See Interactions Docs

• GamepadInteractions: Sets the interactions of the gamepad binding. See Interactions Docs

• ActionID: Overrides the generated actionId (Generally you don't want to change this)

• ActionType: Determines the behavior with which the action triggers. See ActionType Docs

So your Attribute could be written like this:

[InputAction("<Keyboard>/minus", Name = "Explode")]
public InputAction ExplodeKey { get; set; }

Or with any combination of optional parameters:

[InputAction("<Keyboard>/minus", Name = "Explode", GamepadPath = "<Gamepad>/Button North", KbmInteractions = "hold(duration = 5)")]
public InputAction ExplodeKey { get; set; }

[!NOTE] In this case above the Hold Interaction is being used. This keybind triggers after being held for 5 seconds. See Interactions Docs

At Runtime

• Override Method void CreateInputActions(in InputActionMapBuilder builder)
• Use the builder to create InputActions
• Reference InputAction by calling Asset["actionId"] in your class

[!IMPORTANT] Make sure you call Finish() after you're done creating each InputAction.

Here's an example usage of the runtime api

public class MyExampleInputClass : LcInputActions
{
    public static readonly MyExampleInputClass Instance = new();
    
    public InputAction ExplodeKey => Asset["explodekey"];

    public override void CreateInputActions(in InputActionMapBuilder builder)
    {
        builder.NewActionBinding()
            .WithActionId("explodekey")
            .WithActionType(InputActionType.Button)
            .WithKbmPath("<Keyboard>/j")
            .WithBindingName("Explode")
            .Finish();
    }
}

Referencing Your Binds

To use your InputActions class, you need to instantiate it.

[!IMPORTANT] Do not create more than one instance of your InputActions class. If your class is instantiated more than once, your InputActions are unlikely to work as intended.

The easiest (opinionated) way to do so would be to have a static instance in your plugin class.

[BepInPlugin(...)]
[BepInDependency("com.rune580.LethalCompanyInputUtils", BepInDependency.DependencyFlags.HardDependency)]
public class MyExamplePlugin : BaseUnityPlugin
{
    internal static MyExampleInputClass InputActionsInstance;

    public void Awake()
    {
        InputActionsInstance = new MyExampleInputClass();
    }
}

[!IMPORTANT]

But How Do I Get My Binds String?

You may have noticed that <keyboard>/yourKey can be a little confusing for the special buttons. So try this:

1. First, arbitrarily set the value to some regular value or just an empty string
2. Then, load up your mod and change the keybind to the desired key
3. After, look in your .../BepInEx/controls/YOURMODID.json file
4. Find the {"action":"myaction","origPath":"","path":"<Keyboard>/f8"}]}
5. Last, copy that path:"" from the far right i.e. "<Keyboard>/f8"

Using Your Binds

You could then simply reference the instance anywhere you need to have your actions at.

public class MyOtherClassOrMonoBehavior
{
    public void DoSomething()
    {
        MyExamplePlugin.InputActionsInstance.ExplodeKey ...
    }
}

or

public class MyOtherClassOrMonoBehavior
{
    public void DoSomething()
    {
        MyExampleInputClass.Instance.ExplodeKey ...
    }
}

Best Practices

It is common to see tutorials call InputAction.ReadValue<>() or InputAction.triggered from mono-behaviour Update() functions.

public class MyOtherClassOrMonoBehavior
{
    public void Update()
    {
        DoSomething();
    }
    
    public void DoSomething()
    {
        if (!MyExamplePlugin.InputActionsInstance.ExplodeKey.triggered) return;
        
        //Your executing code here
    }
}

This approach is sufficient for 'continuous' actions, e.g. movement.

For 'discrete' actions, it's more appropriate to create event listeners that accept an InputAction.CallbackContext and subscribe to InputAction.performed.

public class MyOtherClassOrMonoBehavior
{
    public void Awake()
    {
        SetupKeybindCallbacks();
    }    
    
    // Name this whatever you like. It needs to be called exactly once, so 
    public void SetupKeybindCallbacks()
    {
        MyExamplePlugin.InputActionsInstance.ExplodeKey.performed += OnExplodeKeyPressed;
    }

    public void OnExplodeKeyPressed(InputAction.CallbackContext explodeConext)
    {
        if (!explodeConext.performed) return; 
        // Add more context checks if desired
 
        // Your executing code here
    }
}

Using InputUtils as an Optional or Soft Dependency

First make sure to add the [BepInDependency(...)] attribute to your mods Plugin class, mark it as a SoftDependency. If you already have the attribute set as a HardDependency make sure to replace that.

[BepInPlugin(...)]
[BepInDependency("com.rune580.LethalCompanyInputUtils", BepInDependency.DependencyFlags.SoftDependency)]
public class MyExamplePlugin : BaseUnityPlugin

Create your InputActions class as you would following the guide above. Make a class specifically for when the mod is loaded

internal static class InputUtilsCompat
{
    public static bool Enabled =>
        BepInEx.Bootstrap.Chainloader.PluginInfos.ContainsKey("com.rune580.LethalCompanyInputUtils");

    public static InputAction ExplodeKey =>
        MyExampleInputClass.Instance.ExplodeKey;
}

Finally whenever you reference stuff from InputUtilsCompat, make sure to check its Enabled Property first.

if (InputUtilsCompat.Enabled)
    InputUtilsCompat.ExplodeKey...

Reference Best Practices for details on how to best use the InputAction

[!IMPORTANT]

If your mod uses NetcodePatcher you may need to do additional steps.

This only applies to mods that use InputUtils as a soft-dependency

Please check their Readme for more info. However for a possible fix, replace

var types = Assembly.GetExecutingAssembly().GetTypes();

with

IEnumerable<Type> types;
try
{
    types = Assembly.GetExecutingAssembly().GetTypes();
}
catch (ReflectionTypeLoadException e)
{
    types = e.Types.Where(t => t != null);
}

[0.7.7]

Fixes:

• I also forgot to include Locale with the new build system, this fixes things for real this time.

[0.7.6]

Fixes:

• Forgot to include AssetBundles with new build system, sorry about that.

[0.7.5]

Fixes:

• Delay searching for device layouts until after unity has loaded, fixes a harmless error at startup.

[0.7.4]

Locale:

• Russian translation by @Singularia

Developer Experience Improvements:

Keyboard, Mouse, and Gamepad have generated Enums under the LethalCompanyInputUtils.BindingPathEnums namespace. These enums are called KeyboardControl, MouseControl, and GamepadControl respectively. These enums contain all the keys/buttons that are accepted by Unity's InputSystem.

The docs have been updated to reflect usage of the Enums, you may still use the string input paths if you'd like.

[0.7.3]

Mod Integration:

• LethalConfig - Use TextDropDownConfigItem for the locale option instead of TextInputFieldConfigItem.

[0.7.2]

Mod Integration:

• LobbyCompatibility - Register InputUtils as a client-side mod.
• LethalConfig - Change locale in-game.

[0.7.1]

It wouldn't be an InputUtils update without a hotfix for bug I never noticed.

Fixes:

• Binds actually save instead of gaslighting you into thinking they saved.

[0.7.0]

Highlights:

• Basic locale/lang loading system
  • Starting with only en_US for now.
  • Configurable
• Global controls
  • Controls can now be saved globally which allows for Controls to work across Modpacks/Profiles.
  • With the addition of Global Controls comes the ability to configure how InputUtils handles Control priority between Local (Modpack/Profile/Manual install) and Global Controls.
    • By default both Local and Global Controls are loaded, but with Global Controls having priority.

Internal Changes:

• Better handling of device specific overrides when serializing/deserializing.

[0.6.3]

Fixes:

• Some Keyboard/Mouse binds were being incorrectly recognized as gamepad only binds, this was because I forgot about the existence of lower-case letters. I've studied up on the alphabet to make up for this.

Notes:

• It was brought to my attention that the wording of the previous description could potentially come across as an insult to the vanilla rebind UI, which was not my intention. As such I have updated the description to more accurately provide an overview of the features provided, while also using more neutral wording.

[0.6.2]

Fixes:

• Gamepad only binds now only allow gamepads.

[0.6.1]

Fixes:

• Empty bind paths for InputActions created using the builder now properly resolve.

[0.6.0]

Features:

• Scroll Wheel rebinding support.
• Mouse button glyphs.

[0.5.6]

Allow LcInputAction's to have NonPublic InputActions.

[0.5.5]

Fixes unbinding vanilla keys to no longer cause the UI to be permanently broken.

[0.5.4]

Hotfix for rebind ui breaking due to another oversight on my part.

[0.5.3]

Fix issue with the runtime api causing errors when not defining a gamepad path.

[0.5.2]

Fix vanilla key rebinding being broken when re-opening the rebind UI.

[0.5.1]

Hotfix for broken installs with mod managers, sorry that was my bad.

[0.5.0]

Highlights:

Massive UI Overhaul

• Cleaned up the base game controls to be more organized.
• Added Controller Glyphs for Xbox and DualSense controllers with automatic detection.
  • Glyphs only show up in the rebind menu for now, a future update will have them be visible in game.
  • Api to request controller glyphs for a control path will be available in a future update.
• Controls added by mods are seperated by mod.
• Controls manually injected into the vanilla ui by mods are available in "Legacy Controls".

Controls can now be unbound.

Controller navigation of the new UI is still a WIP, hoping to improve it in a future update.

[0.4.4]

Text in the remap ui now has auto-scaling size. Remap ui no longer cuts-off the bottom of the controller section. Changed method for determining the BepInPlugin of dependents.

[0.4.3]

LcInputActions.Asset now has a public getter. Fixed issue where binds that were unbound by default would not save/load their new binds after restarting your game.

[0.4.2]

Hotfix for applying migrations when the new file already existed, no longer crashes the mod.

[0.4.1]

Bind overrides have been moved from BepInEx/controls to BepInEx/config/controls allowing for bind overrides to be distributed with modpacks.

[0.4.0]

InputActions can now be made at runtime by overriding the method CreateInputActions(...) and using the provided builder.

[0.3.0]

The only required parameter for the InputActions attribute is now only just the kbmPath, the rest are now optional. Should help improve DX.

[0.2.0]

Interactions for the kbm and gamepad bindings can now be set in the attribute.

[0.1.0]

Initial Beta Release.
