MultiTags Released!

Will this work with Unity 4.3.X ?

 

in 4.6.1: BCE0019: 'HasTag' is not a member of 'UnityEngine.GameObject'.
though the MultiTags script is on a gameobject, and has local and global tags assigned (?)

 

hmm works fine in all my builds...Tested in Unity 4.6.1, 4.6.2, 4.6.3, and 5 beta

I wonder if the conflict is because of another asset or package in the project? MultiTags doesn't do anything special it should be fine for a good long time.

 

Hi, is possible a video tutorial? Thx

 

How would you go about finding all gameobjects that have more than one tag? Say I want to find all objects that have the tags "Dog" and "Brown"? Thanks!

 

Something tells me you like dogs, although I can't put my finger on why. Code: After thinking about it I don't think my framework can do what you ask. Although its a really cool idea. I will warn however against doing that. If you were doing intricate list searching with infinite levels like that it could really slow down your game/project(on Update calls). The code is pretty straight forward to add it on the outside. I would just have a list of object x and do another comparison of those game objects for object y. Does that help?

 

Sorry I just saw your message I will absolutely put together a video tutorial asap!

 

Yeah, makes sense. Was curious

Cheers.

 

Excellent plugin. Totally does what I want.

One thing that would be really cool, is if the Multitags could have data attached (which can be amended). Easy enough to handle yourself, but would be really convenient if could find all objects with a MultiTag (as you can now), and then with a similar command get values attached to other MultiTags against the same object.

For example instead of this:-

Code (CSharp):

1.         GameObject[] enemies = MultiTags.FindGameObjectsWithMultiTag("Enemy");
2.         foreach (GameObject enemy in enemies)
3.         {
4.             stats enemyStats=enemy.GetComponent<stats>()
5.             if(!enemyStats.boss)enemyStats.energy--;
6.         }

Then this:-

Code (CSharp):

1.         GameObject[] enemies = MultiTags.FindGameObjectsWithMultiTag("Enemy");
2.         foreach (GameObject enemy in enemies)
3.         {
4.             if(!enemy.TagData("Boss"))enemy.TagData("Energy")--;
5.         }

Something like that anyway. Basically a way of quickly accessing (or attaching) data connected to any object, without mucking around.

Cheers

 

First congratulations for an excellent product!

I am using playmaker with arraymaker.
I am using MulitTags to add tags to various objects which are in an array.

there is a playmaker action with arraymaker which find closest gameobject in the array.

I would like to customize this action so I can look for object with a multi-tag.

I am sorry but do not have enough programming knowledge to accomplish this, could you help out with this?
Thanks in advance.

Code (CSharp):

1. using UnityEngine;
2.  
3. namespace HutongGames.PlayMaker.Actions
4. {
5.     [ActionCategory("ArrayMaker/ArrayList")]
6.     [Tooltip("Return the closest GameObject within an arrayList from a transform or position.")]
7.     public class ArrayListGetClosestGameObject : ArrayListActions
8.     {
9.         [ActionSection("Set up")]
10.        
11.         [RequiredField]
12.         [Tooltip("The gameObject with the PlayMaker ArrayList Proxy component")]
13.         [CheckForComponent(typeof(PlayMakerArrayListProxy))]
14.         public FsmOwnerDefault gameObject;
15.        
16.         [Tooltip("Author defined Reference of the PlayMaker ArrayList Proxy component ( necessary if several component coexists on the same GameObject")]
17.         public FsmString reference;
18.        
19.         [Tooltip("Compare the distance of the items in the list to the position of this gameObject")]
20.         public FsmGameObject distanceFrom;
21.        
22.         [Tooltip("If DistanceFrom declared, use OrDistanceFromVector3 as an offset")]
23.         public FsmVector3 orDistanceFromVector3;
24.        
25.         public bool everyframe;
26.        
27.         [ActionSection("Result")]
28.        
29.         [UIHint(UIHint.Variable)]
30.         public FsmGameObject closestGameObject;
31.        
32.         [UIHint(UIHint.Variable)]
33.         public FsmInt closestIndex;
34.        
35.        
36.         public override void Reset()
37.         {
38.        
39.             gameObject = null;
40.             reference = null;
41.             distanceFrom = null;
42.             orDistanceFromVector3 = null;
43.             closestGameObject = null;
44.             closestIndex = null;
45.            
46.             everyframe = true;
47.         }
48.        
49.        
50.         public override void OnEnter()
51.         {
52.  
53.             if (! SetUpArrayListProxyPointer(Fsm.GetOwnerDefaultTarget(gameObject),reference.Value) )
54.             {
55.                 Finish();
56.             }
57.            
58.             DoFindClosestGo();
59.            
60.             if (!everyframe)
61.             {
62.                 Finish();
63.             }
64.            
65.         }
66.        
67.         public override void OnUpdate()
68.         {
69.             DoFindClosestGo();
70.         }
71.        
72.         void DoFindClosestGo()
73.         {
74.            
75.             if (! isProxyValid())
76.             {
77.                 return;
78.             }
79.            
80.             Vector3 root = orDistanceFromVector3.Value;
81.            
82.             GameObject _rootGo = distanceFrom.Value;
83.             if (_rootGo!=null)
84.             {
85.                 root += _rootGo.transform.position;
86.             }
87.            
88.             float sqrDist = Mathf.Infinity;
89.        
90.             int _index = 0;
91.             float sqrDistTest;
92.             foreach(GameObject _go in proxy.arrayList)
93.             {
94.                
95.                 if (_go!=null)
96.                 {
97.                     sqrDistTest = (_go.transform.position - root).sqrMagnitude;
98.                     if (sqrDistTest<= sqrDist)
99.                     {
100.                         sqrDist = sqrDistTest;
101.                         closestGameObject.Value = _go;
102.                         closestIndex.Value = _index;
103.                     }
104.                 }
105.                 _index++;
106.             }
107.  
108.         }
109.        
110.     }
111. }

 

I'm trying to write a switch based on the tags, that would look like the following:

Code (CSharp):

1. private string selectedObjectTag = selectedobject.gameobject.tag;
2.  
3.      switch (selectedObjectTag) {
4.          case "Tag1":
5.              Debug.log("Tag1");
6.              break;
7.            case "Tag2":
8.              Debug.log("Tag2");
9.              break;
10. }
11.  

However, selectedObject.gameobject.tag would only check on native Unity tags, not on MultiTag tags. I probably missed it somewhere as I don't believe you don't have a function to check the tag(s) of an object, but how do I do this?

 

Forget this, I removed Mulitags and used sqlite instead.

G.

@charmandermon ,

Just asking whether this Asset is still being developed? Any plans to help with Playmaker FSMs to support new Playmaker Arrays? Also, is it Unity 5.4 compatible?

Also, an (albeit slower) way to search for a GO or array of GOs or count of GOs by multiple MultiTag strings at once would be neat? If not, how would I code it?

 

@charmandermon

Any chance of help in making a Playmaker collide2d tag action?

 

@charmandermon ,

Now Playmaker arrays are fully there, any chance of updating this asset to support them?

 

Ya sure, that doesn't sound too complicated. How do you want it to function? - Dustin

 

A playmaker array of tags. Searching action for objects with one or more of tags in Playmaker...?

 

Hi, I have created an extension for searching objects with specific tags

@Amalfi-Prozen ,

Thanks for that ... would your method allow me to search for gameobjects which all had 3 specific tags?

Also, how fast are your 2 methods?

 

yer, there is an array of string (any element is a tag)

 

Great thanks

 

I change the script for refactoring XD

 

Does this still work on the last version of Unity 2017? I'm not concerned with 2018 beta, at least not until the upload the new substance plugin

 

I have written a range of additional MultiTag helper functions to extend its capabilities for some game ideas I am working on, and I have written PlayMaker Actions for each new function added to MultiTags as well. Primarily I am doing things like checking ifan item contains multiple assigned MultiTags compared to an input list. Some examples of what I am creating are things like HasTagsCount(tagsToCheck) and HasTags(tagsToCheck) the first returns an int count of the matches found while the second returns a string array of matches. Some other functions allow for the use of wildcard searches as well. Anyways, I am currently struggling with two things and I thought I would turn to the community and the developer for help.

1) I would like a to make an array of existing global tags in the either the MultiTags class or the MultiTagsHelperMethods class but find myself unable to do so. Either way I would like this list to be accessible to the functions and routines within both classes.
2) I am running into an issue where I would like to drop multiple prefabs in the scene and then assign the different tags in the inspector. Currently Unity will allow me to assign the tags on each prefab instance in the scene individually, but the moment I hit play to test the scene the instance specific MultiTag values are wiped out and the prefab state (no tags) is used. I can then make tagging changes at run-time and the rest of my scripts and actions work but I would really like to have the ability to set tags on prefabs and on instances as well. Any thoughts?

 

When I add the multitags component to a prefab and assign global tags to local tags, the next time I open the prefab, the local tags are empty. Seems it is not storing the local tags.

Am I doing something wrong?

Thanks
Andy

 

Just observed similar behavior in Unity 2018.3.11, except that when instancing the prefab at run time the tags go missing and there's just one local "Untagged" tag. Guessing this asset hasn't been updated for the current prefab functionality and looks like it's abandoned... probably gonna have to dig into source and fix it ourselves.

WORKAROUND:
I just discovered if I adjust the order of another component in the prefab editor after adding tags they stick (although it still generates an "Untagged" tag at runtime in addition to the ones I specify). My guess is the editor scripts aren't flagging a dirty flag appropriately in MultiTags when you assign/unassign a tag, but I don't have time to check right now.

FIX:
Found a fix. See post below.

 

sampenguin
Thanks for pointing this out.
I think I will not use this asset in my production because it is too risky to work with unsupported software.

 

I figured out a fix. Add these two lines inside the "if(GUI.changed)" block at the bottom of MultiTagsInspector.cs.

EditorUtility.SetDirty(myScript);            EditorSceneManager.MarkSceneDirty(myScript.gameObject.scene);

I've used this package in multiple shipped games. It is really quite handy for multi tagging. This is the first problem I've encountered with it, and since it's an editor only issue not really much of a risk. YMMV

 

Hey that is good news. Will have a look at it!

Thanks for posting this!

 

I am using Multitags with playmaker and I think i am doing something Dumb with "HasTag" Action

In this Action how does the has "Has Tag" Bool funtion? If I put a custom Bool there, will it set to true if the object has the specified Tag, and to False if it does not?

thank You for Your time
