Hold click to interact in context sensitive method

Housein

I use context sensitive interaction method.
I want to have the ability to
press and hold left mouse button on a hotspot and select it as an inventory item.

You would need a custom script that, when attached to the Hotspot, listens for when the Hotspot is selected by the Player and then reacts to input:

using UnityEngine;
using AC;

public class HoldToSelectHotspot : MonoBehaviour
{

    public float maxHoldTime = 1f;
    public int inventoryItemID = 0;

    private bool canDetectHold;
    private float holdTime;

    private void OnEnable ()
    {
        EventManager.OnHotspotSelect += OnSelect;
        EventManager.OnHotspotDeselect += OnDeselect;
    }

    private void OnDisable ()
    {
        EventManager.OnHotspotSelect -= OnSelect;
        EventManager.OnHotspotDeselect -= OnDeselect;
    }

    private void Update ()
    {
        if (canDetectHold && Input.GetMouseButton (0) && KickStarter.runtimeInventory.SelectedItem == null)
        {
            holdTime += Time.deltaTime;
            if (holdTime > maxHoldTime)
            {
                holdTime = 0f;

                if (KickStarter.stateHandler.IsInGameplay ())
                {
                    KickStarter.runtimeInventory.SelectItemByID (inventoryItemID, SelectItemMode.Use, true);
                }
            }
        }
    }

    private void OnSelect (Hotspot hotspot)
    {
        if (hotspot == GetComponent <Hotspot>())
        {
            canDetectHold = true;
            holdTime = 0f;
        }
    }

    private void OnDeselect (Hotspot hotspot)
    {
        if (hotspot == GetComponent <Hotspot>())
        {
            canDetectHold = false;
        }
    }

}
