UI Prefabs

HNS needs to know, where to find the different UI elements on your marker. Each feature needs specific UI elements to work properly, so make sure to correctly assign them.
The most simply way to get started is to duplicate any UI prefab and customize it to your needs. You'll find the prefab in the prefabs folder:
Sickscore Games > HUD Navigation System > _Examples > HUDPrefabs.

Custom Transforms
Custom Transforms are an easy way to add custom logic to HUD Navigation Elements. We use this mechanic in our example scenes to create the item pick-up.
Custom Transforms can be used to include custom logic to HUD Navigation Elements, such as item pick-ups, interactions, ...
Settings
Name: Enter a unique name, which will be used to access this transform in code
Transform: Assign the transform with your custom logic
Code Example
Show/hide a custom icon on the indicator, if an element is within the defined radius. How to get this example to work:
1.Add a custom transform to your indicator UI Prefab
2.Your Custom Transform must be named "customIcon" (see code)
3.Create a new C# script and copy&paste the code below
4.Select the HUD Navigation Element or Element Setting you want to use
5.Assign these methods to their corresponding Events:
OnEnterRadius: OnIndicatorEnterRadius()
OnLeaveRadius: OnIndicatorLeaveRadius()

using UnityEngine;

using SickscoreGames.HUDNavigationSystem;

	void ShowCustomIndicatorTransform (HUDNavigationElement element, NavigationElementType type, bool visible)
19
	{
20
		// we're only interested in indicator events
21
		if (!type.Equals(NavigationElementType.Indicator))
22
			return;
23
​
24
		// check if indicator exists
25
		if (element.Indicator != null)
26
		{
27
			// show/hide our custom icon, if it exists
28
			Transform customIcon = element.Indicator.GetCustomTransform("customIcon");
29
			if (customIcon != null)
30
				customIcon.gameObject.SetActive(visible);
