a multi-tagging system that overides unity's default tagging system
Download the package from here. And import the package to your project.
- this takes in the tags you set in the UnityEditor and puts it in a static class Tags.
- this is required each time you add or delete custom tags from the editor.
This component overrides Unity's own tagging system. If you need to add a new tag, go to drop-down at the top of the inspector besides the Tag label > Add Tag.
As a general best practice, you should pre-load all the tags you need in editor. You cannot create new tags during runtime, only add existing tags that's within the editor.
To be able to query GameObjects that's implementing the MultiTagComponent use the static Query(MultiTagFilter multiTagFilter) function from MultiTag static class.
public class SimpleMono : MonoBehaviour
{
private void Start()
{
//Querying for GameObjects
var list = MultiTag.Query(new MultiTagFilter
{
//Any gameObject that has these tags
Any = new string[] { "EditorOnly", "Player" }, //You can use a literal string so long as it exists as a Tag.
//gameObjects that do not have these tags
None = new string[] { Tags.Finish } //Tags.Finish is constant for string "Finish"
});
foreach (var val in list)
{
var mtcomp = val.GetComponent<MultiTagComponent>();
//Adding and removing tags via MultiTagComponent;
mtcomp.RemoveTag("EditorOnly");
mtcomp.AddTag(Tags.GameController);
}
//Getting a single gameObject
//This gets the first result.
var gameObject = MultiTag.GetGameObject(Tags.Player);
//Getting only a GameObject based on query
//Another way of getting only the first result with MultiTagFilter
gameObject = MultiTag.SingletonQuery(new MultiTagFilter
{
All = new string[] { Tags.Player },
None = new string[] { Tags.Untagged }
});
//Check if gameobject tagged with Finish tag
MultiTag.IsGameObjectTaggedWith(Tags.Finish, gameObject);
}
