Custom inputs

Custom inputs can be registered through the InputManager singleton. You must hook into the InputRegister event, and create all your inputs within your event handler.

Example

First, within Awake in your mod class, create register handler for the InputRegister

private void Awake()
{
    InputManager.Instance.InputRegister += registerInputs;
}

Next, register your inputs within the handler using the RegisterInput command from InputManager. This version of RegisterInput takes a string argument for the key name (this MUST be unique), and a UnityEngine KeyCode as the default arguments

private void registerInputs(object sender, EventArgs e)
{
    // Init menu toggle key
    InputManager.Instance.RegisterButton("TestMod_Menu", KeyCode.Insert);
}

Now, to use our input, we can use the ZInput class provided by Valheim:

private void Update()
{
    // Since our Update function in our BepInEx mod class will load BEFORE Valheim loads,
    // we need to check that ZInput is ready to use first.
    if (ZInput.instance != null)
    {
        // Check if our button is pressed. This will only return true ONCE, right after our button is pressed.
        // If we hold the button down, it won't spam toggle our menu.
        if (ZInput.GetButtonDown("TestMod_Menu"))
        {
            showMenu = !showMenu;
        }
    }
}
