Mousewheel-scrolling through lists

This script allows you to offset element slots (e.g. a DialogList or InventoryBox) with the mousewheel. To use it: ScrollWheelMenuList.cs: using UnityEngine; using AC; public class ScrollWheelMenuList : MonoBehaviour { 	[SerializeField] private string inputName = "Mouse ScrollWheel"; [SerializeField] private float inputThreshold = 0.05f; [SerializeField] private string menuName = "Conversation"; [SerializeField] private string elementName = "DialogueList"; private bool allowScrollWheel; private bool menuIsOn; private bool hasCanvas; private void OnEnable { 		EventManager.OnMenuTurnOn += OnMenuTurnOn; EventManager.OnMenuTurnOff += OnMenuTurnOff; hasCanvas = (GetComponent != null); } 	private void OnDisable { 		EventManager.OnMenuTurnOn -= OnMenuTurnOn; EventManager.OnMenuTurnOff -= OnMenuTurnOff; } 	private void Update { 		if (menuIsOn || hasCanvas) { 			float scrollInput = Input.GetAxisRaw (inputName); if (scrollInput > inputThreshold) { 				if (allowScrollWheel) { 					PlayerMenus.GetElementWithName (menuName, elementName).Shift (AC_ShiftInventory.ShiftPrevious, 1); allowScrollWheel = false; } 			}  			else if (scrollInput < -inputThreshold) { 				if (allowScrollWheel) { 					PlayerMenus.GetElementWithName (menuName, elementName).Shift (AC_ShiftInventory.ShiftNext, 1); allowScrollWheel = false; } 			}  			else { 				allowScrollWheel = true; } 		}  	}  	private void OnMenuTurnOn (Menu menu, bool isInstant) { 		if (menu.title == menuName) { 			menuIsOn = true; } 	}  	private void OnMenuTurnOff (Menu menu, bool isInstant) { 		if (menu.title == menuName) { 			menuIsOn = false; } 	}  }
 * 1) Create a new C# script named ScrollWheelMenuList.cs, and paste in the code below
 * 2) For each element you wish to enable scrolling for, place an instance of the script in the scene.  For Unity UI-linked Menus, the script can be attached to the prefab's root Canvas.
 * 3) Configure the Inspector values.  You will need to ensure that the Input Name field matches an Input defined in Unity's Input Manager.
