MultiTag System for Unity

This package allows you to Tag your Game Objects with ScriptableObjects.

Features:

• Allows to put as many Tags on your object as you want
• Adding and Removing Tags via Inspector and Code (Works faster in Build than in Editor because of the Inspector updating when adding and removing tags)
• Work with SO Assets instead of strings
• Works few times faster than Unity Tag Comparer

Examples:

Change Tags in Editor:

Runtime Operations:

Code

public class Test : MonoBehaviour
{
	[SerializeField] private GameObject _enemy = null;
	[SerializeField] private Tag _zombieTag = null;
	[SerializeField] private TagsContainer _allEnemiesTags = null;
 
	private void Awake()
	{
		// Check for Tag
		if (_enemy.HasTag(_zombieTag))
		{
		
		}
		
		// Check for Multiple Tags
		if (_enemy.HasTags(_allEnemiesTags, allRequired: false))
		{
		
		}
		
		// Adding Tag
		_enemy.AddTag(_zombieTag);
		
		// Removing Tag
		_enemy.RemoveTag(_zombieTag);
	}
}

Tags Container Usage:

Tags Container allows you to group tags in a single asset, which allows you to check a single object for multiple tags at once. In my games, I use containers most often for a system of relationships between entities.

Performance Test:

Code

using Sirenix.OdinInspector;
using System.Diagnostics;
using ToolBox.Tags;
using UnityEngine;

namespace ToolBox.Test
{
	[DefaultExecutionOrder(-100)]
	public class Tester : MonoBehaviour
	{
		[SerializeField] private Tag _myTag = null;
		[SerializeField] private string _unityTag = null;
		[SerializeField] private GameObject _object = null;

		private const int ITERATIONS = 100000;

		[Button]
		private void MyTagTest()
		{
			Stopwatch stopwatch = new Stopwatch();
			stopwatch.Start();

			for (int j = 0; j < ITERATIONS; j++)
			{
				_object.HasTag(_myTag);
			}

			stopwatch.Stop();
			UnityEngine.Debug.Log($"Scriptable Object Tag Comparer: {stopwatch.ElapsedMilliseconds} milliseconds");
		}

		[Button]
		private void UnityTagTest()
		{
			Stopwatch stopwatch = new Stopwatch();
			stopwatch.Start();

			for (int j = 0; j < ITERATIONS; j++)
			{
				_object.CompareTag(_unityTag);
			}

			stopwatch.Stop();
			UnityEngine.Debug.Log($"Unity Tag Comparer: {stopwatch.ElapsedMilliseconds} milliseconds");
		}
	}
}
