iTween Visual Editor

Current version: 0.6.1, released October 24, 2012

Get the editor from the Unity Asset Store.

Please consider donating if you find the visual editor helpfulThe iTween Visual Editor is an open source project released under the MIT license. If you find it helpful and want to contribute to its future development, please consider making a donation.

The iTween Visual Editor is a Unity 3, editor component that allows you to set up almost any iTween tween visually vs requiring code. So you can replace this


with a nice Unity inspector view such as the image to the right (click to enlarge). This is accomplished by adding an iTweenEvent component to the GameObject you wish to tween. You can have your tweens run automatically, after a delay, or when triggered via the Play method on the iTweenEvent component. You can also have multiple iTweenEvent components on your GameObject and get them via the iTweenEvent.GetEvent method which looks up an event by name (version 0.3 and later). For an example of this, please look at this example project which demonstrates using a script to start a particular tween on another object.

Starting with version 0.5 a copy of iTween and the iTween Path Editor are included in the unitypackage. If you have your own copy or wish to use a different version, you can uncheck iTween.cs, iTweenPath.cs and iTweenPathEditor.cs during the package import.

The visual editor will only compile under Unity 3 and later. If you are using 2.6 and wish to use the editor it is possible to get it running under 2.6, you will have to remove the usage of Linq methods. I have no intention of supporting 2.6 so unless you’re going to pay me to do it, don’t bother writing and asking when it will be done.

Known Issues: None!

    First thank you so much for adding a visual editor to iTween. Been playing around putting tween effects on objects. Wanted to know is it possible to use the visual editor for OnGUI functions? For instance scale a gui window with bouncy effect. Can’t seem to get it to work.

    Thanks very much

      January 19, 2011 at 12:23 pm

      Well the visual editor works just about everywhere that iTween itself works. Can you provide an example of what you’re trying to do via plain iTween code and then I can tell you if the visual editor supports that.

      • Hakimo
        January 21, 2011 at 12:45 am

        Not sure if it’s the right way but I just made an empty game object. Added a javascript that uses OnGUI:
        //start code
        function OnGUI () {
        // Make a background box
        GUI.Box (Rect (300,10,300,90), “My Menu”);

        //First Button
        if (GUI.Button (Rect (310,40,280,20), “First Button”)) {
        print(“Do something”);
        //Code ends

        Then I attached the iTween event and wanted to scale the GUI. There’s no errors but nothing happens…

        Thanks very much.

        To do what you’re wanting you’d need the ValueTo function of iTween. Unfortunately that requires custom code so there’s no current way to replicate that sort of functionality from the visual editor.

    I’ve been thinking about learning scripting for a while, as an artist, I can get a lot done in unity without scripting, but you still need some of it to get by. I just discovered itween the other day… And this today. My jaw is still on the floor – I can setup a lot of prototyping now with just these two things, and get a lot of playtesting without writing a single line of code! Absolutely amazing!

    • dkoontz

      Glad to be of help, let me know if there’s stuff you have problem with.

      • larvantholos
        January 25, 2011 at 4:12 am

        Not so much as a problem, but more of a question. I’ve been toying with this, to see if I can get what I want out of it. Its clear I’ll still need to get some scripting done to get what I need – but I’m curious, do the Oncomplete (and etc boxes) accept any input currently?

        I also notice when trying to do multiple events, it tends to complete the last one first – I was trying to complete a simple elevator with a loop, adding a delay, and actually no matter what I did, it would do the MoveFrom first – even if I set it to a long delay.

        Would it be useful in future versions, to have multiple tweens setup in a single script, so you can loop back on the events? Just so that you could make better use of the From functions?

        This has been pretty neat to use tho, I can see how setting up these scripts fast through this, and then triggering it externally, would get the desired result fairly quickly tho. Some sort of ability to chain these together, without having to write a script would be neat, but I also see that might be beyond the current idea of how this is.

        Still peeling my jaw off the floor tho 😀

        So, I was doing more tweaking for what I specificly wanted, and I realized that if I just use the ping pong loop, it works just fine.

        I notice there is a bug specificly in setting the time however.

        If I set the time to 6, it should do the animation over 6 seconds, instead it is doing it extremely fast. If I set it to something like .5 it should be doing the animation in .5 of a second, instead its doing it extremely slow. I’m pretty sure this is the opposite of what is supposed to be happening here!

      • dkoontz
        January 25, 2011 at 4:06 pm

        larantholos, I just tried both the things you’re having problems with (setting a delay for the 2nd event and changing the time) and they both worked fine in my test scene. Could you post a screenshot of all your settings or list them out somewhere? My guess is things are just misconfigured.

        MoveFrom seems like a strange event to be happening after another event as it moves your object to the specified location at the beginning of the tween, not sure how you would use that for an elevator.

        As for the oncomplete events, they accept a string for their parameter, so you could have a script that interprets that parameter as the next event to trigger and have a very easy system for chaining events that way instead of having to work out the delays.

    Thanks very much. I thought it should be custom code. Trouble is, I’m finding it hard to use iTween using code. I can move objects etc but I can’t animated gui buttons. I’m finding it hard understanding on how to use the hashtables arguments. Hope you can help.

      For iTween help you should really head over to the Unity forums. Bob, the author of iTween can help you out there, or check out the iTween home page which has a variety of documentation. I’m sure between the two of those you can figure it out.

    Hi, thanks for following up. Actually, I suspect I got the time, and speed mixed up. I just confirmed that >.< Thats what I get for messing with things at 4am 🙂

    As for the oncomplete – a full hash string, or just the relevant part of the arguement as it would normally appear in the hash string?

    Thanks again!


    • dkoontz
      January 25, 2011 at 4:24 pm

      The oncompleteparam is just a string param to your oncomplete function. It has nothing to do with the iTween hash.

      You have 2 copies of iTween in your project. If you downloaded it separately then you either need to delete that version or the one that comes with the visual editor.

    I’m curious… Is it possible to have a MoveTo function (created in iTween Visual Editor) move along a path created in iTween Visual Path Editor? I know you can have a MoveTo function traverse a path of multiple points by manually entering the path points in iTween Visual Editor, but thought it would be really great to just have the MoveTo function use a path I created in Visual Path Editor… Is this possible?

    • larvantholos
      February 6, 2011 at 9:08 pm

      It will automatically grab the path, if its attached to your game object. If you drag the path edit plugin onto the object itself, then add the visual iTween event, you can select the path, and the path button, and it will find it.

      • dkoontz
        February 6, 2011 at 11:27 pm

        Actually the path option now finds all paths in the scene not just the ones on the local game object.

  11. larvantholos
    February 7, 2011 at 12:24 am

    Is that in the .2 update? If not, it does not. Instead I get an error. I’ll replicate the error in a few, as I’m at work, and not at home, I’ll also make sure I have to current version so I can say for sure. However, testing at home it only found the path when I placed it on the object itself.

    • larvantholos
      February 7, 2011 at 12:55 am

      This is the error – Made sure I had the current version. Its all greek to me 😀
      I am making the paths by dragging the path plugin onto the object (in this instance a cube) and naming the path, going to select it, throws this error. I do not however get this, if I drag the path onto the object (another cube in this case) that is running the Tween through the visual editor.

        So I got the idea to download the one from the asset store – and it seems to not have this issue, and finds all the paths as it should. Seems then, your package here is broken 🙂 solution – download from the asset store.

      • dkoontz
        February 7, 2011 at 8:34 am

        The current version is 0.5.2 which I submitted to the Asset Store over the weekend. The path support wasn’t added until 0.5.1 so 0.2 definitely won’t work (as well as being very out of date).

  12. larvantholos
    February 7, 2011 at 8:52 am

    Note that, this seemed to work fine with 5.1 but not with 5.2 🙂 I ment I was using 5.2 😛

    Thanks and by the way great tool.

    • dkoontz
      February 7, 2011 at 9:16 pm

      Set up a moveto as normal, in the oncomplete field type in the name of a function, something like DeleteMe. Create a script that contains a function named the same thing that you put in the oncomplete field, in my example here that’s DeleteMe. Inside that script put “Destroy(gameObject)”. Attach that script to your object that has the tween and you’re all set.

    Guys… as one of the examples written above, I’m a digital artist too and I’m just starting with Unity and this whole thing and scripting its still VERY, VERY, VERY complicated for me… and this tool saved my day. Being used with timeline animations in Flash and Aftereffects, the whole tweening thing makes a lot of sense for me, and your tool just makes it SO EASY that I want to jump on my chair of hapiness…

    Seriouslly SUPER COOL STUFF. Keep it up.

    And one question, if I do want a cube to move to a position and get back to the old position and move again, like in an infinite loop? Any hints. Thanks! And greetings from Brazil.

    “Instance of iTweenPathEditor couldn’t be created because there is no script with that name.”

    That’s weird, because there is clearly a script with that name in my Assets/Plugins/iTween/iTweenPath/Editor folder. Do you know what’s wrong?

    My previous project was actually based on this very script and they all somehow broke.. has anyone else been having this issue.

    I have the editor from the store. I have moved the scripts around so that the reference errors go away. I get the Menu entry, although it comes and goes. I add an event to my MainCamera and I get nothing in the Inspector for MainCamera that looks anything like the example. The word Position isnt there at all????? I get:

    Script iTweenEvent
    Tween Name
    Play Automatically checked
    Delay 0
    Type MoveTo
    Show Icon in Inspector checked

    Vector 3s
    Ease Types
    Loop Types
    Game Objects
    Audio Clips
    Audio Sources
    Vector 3Arrays
    Transform Arrays

    And that is it.

    I know I am doing something stupid, but I am at a loss, I looked through the scripts and the word Position only displays as a comment in one file.
    What am I doing wrong??

    After much pain, I found a version in the package format, I dropped the contents into my project and there they where.
    Thanks for some nice scripting. Hope unity fixes the menu instability thing, but dropping the event on the object isnt a painful workaround so it isnt a bother. It will make more aggressive plugins hard to create though.

    April 6, 2011 at 7:17 pm

    I am having issues with this for some reason as well… I put the full iTweenEditor folder in the Editor folder. Then i copied the iTween and other 2 scripts into the Plugins folder. Then i copied the icon into the icon folder. But i get a bunch of these errors and before i got the errors it would not give them but would do nothing and then the menu item disappeared.

    Any ideas?

      OK so i did some guessing and got it all fixed… Here is what i did for anyone else that has my same problems..

      I deleted everything then started over… I moved the whole iTweenEditor folder to the Editor folder, Then i moved the Gizmo to the Gizmo folder, Then i moved the iTween and iTweenEvent and iTweenPath and the Helper Classes folder to the Plugins folder…

      And that fixed all my problems.. Works great now. Thanks!!!

I get no errors, everything that was using ITween are still working but the visual editor is NOT appearing in the components menu why? And more importantly, how to make it work?

        Yeah I don’t know why that Unity bug happens. If you don’t have the component menu item you can always just drag an iTweenEvent script onto your object and you’ll see the editor appear. Kind of clunky but it works.

  27. Quentin Holmes
    April 17, 2011 at 7:12 pm

    • dkoontz
      April 19, 2011 at 10:34 pm

      I don’t know of any issues with updating, if you did run into something you could always just revert your iTween version back to the bundled one.

  29. Quentin Holmes
    April 19, 2011 at 10:23 pm

    Ok so if i leave the On Complete Target blank then it will run iTweens on the same object fine but i can not get a different iTween from a different object to work even if i drag the object onto the Target variable…
    And why does the OnComplete iTween action fire right away and not when the iTween is done.. This messed me up as it was actually doing something but not until i put a delay on the second one did i actually see it doing something as they were cancelling them selves out.

    And how can a run a Method directly? I am using EZ Gui and would like to fire an iTween action right from a button but i dont know how to pass the proper method to the button. Right now i use a script in between the two to run the iTween.

  30. Quentin Holmes
    April 19, 2011 at 11:59 pm

    Ok i take it back… the running a second iTween from OnComplete that is on the same object is not working… the reason it was firing right away was because i was calling it from my other script.

    So my question still is… why cant i get the OnComplete to work from the visual editor?

    • dkoontz
      April 20, 2011 at 12:51 am

      I’m testing this now and updating the bundled example scene to show off how to do this.

    • dkoontz
      April 20, 2011 at 1:17 am

      I’ve just submitted a new package to the asset store, it should be up whenever they approve it. That new package has an example directory with a scene that includes an object using a callback on the same GameObject and a callback on another GameObject so hopefully that will demonstrate how to use them. Let me know if it’s still unclear.

      That warning appears on many components authored before Unity 3.4, it can be safely ignored. If the iTween item is not showing up in the menu, (it seems to disappear and reappear at random), then you can just drag the iTweenEvent script onto whatever object you want to attach it to. The editor will still show up.

    Hello, I had fixed the warning about “ObjectField”, and it already be tested in unity 3.4.2.
    I use version check and reflection to avoid warning. You can look it at

    Hi there,

    I’d like to be able to script positions and other parameters apart from having an initial iTweenEvent component on my GameObject. How can I access and update these parameters via iTweenEvent?

      The iTweenEvent just starts an iTween playing. I’m not sure what parameters you’re talking about that aren’t exposed via the iTweenEvent.

    Hi, could I check if the ValueTo() tween is going to be made available in the Visual Editor?

    • dkoontz
      September 19, 2012 at 12:46 pm

      ValueTo was not included because there’s no way to use ValueTo without writing code to apply the value to whatever it is you’re tweening. As as result, doing iTween.ValueTo directly is almost certainly easier that using a visual editor. If you have a really compelling use case for ValueTo to be part of the visual editor I’d be happy to hear it though.

    Hi, I found a bit of a problem at EventParamMappings.cs:663, that “ShakePosition” has no “space” parameter and has “islocal” parameter. Thank you for cool tool!

    Just thought I would say thanks. Visual Actions works flawlessly with iTweens, thanks to this Visual Editor. Watch the video for yourself:

      There’s a little disappointment that real-time value changes cannot display in the ‘Game View’ realtimely. How about this suggestion? I look for your reply.

    Thank you so much. However, I dont think its working correctly as of 06/2014. I followed the tutorials to the T but nothing actually works and I get ALOT of compiler errors.
    Is there another version to be downloaded or perhaps some tutorials from this year?
    maybe the import was corrupted? i dont know but I would love to use it!

    Dear Mr. Koontz,
    Thank you for making this free editor!!! I haven’t tried it yet, but I plan to do so now. I was wondering, what is your policy for credit attribution for games made using this editor? Would that be Creative Commons attribution, or a GNU agreement, or what? Please reply soon. Thanks ever so much!


    • August 11, 2014 at 8:16 pm

      The code is MIT licensed which means you don’t have to do anything. You can credit me if you want to but nothing is required.

    Really excited about this asset, but cannot get it to work with Unity 4.5.2f1.

    I’ve read this entire thread and searched abroad, but nothing is working for me. I have deleted/reinstalled the assets 3x, opening and closing Unity each time. I cannot pull up iTween in the Component menu and a drag/drop of any Editor script results in a “Can’t add script” message regarding a mismatched file and class name.

    Any help would be greatly appreciated!

      Just tried to install ONLY the iTween Visual editor and received this error (not sure if I’ve overlooked it before):

      Assets/iTweenEditor/Editor/iTweenEventDataEditor.cs(292,48): error CS0433: The imported type `iTween’ is defined multiple times

      • August 27, 2014 at 8:09 pm

        Got it! You can delete my comments upon moderation, if necessary.

        I was confused just as others were after the installation of all three packages, but finally realized that the original iTween was “hiding” in a Plugins folder that I found only after browsing my scripts for duplicates relating to the CS0433 error.

        It’s great that after version 0.5 all the necessary iTween assets are included in this one package, but many like myself must have landed here after finding/installing the others first.

        Can’t wait to get to work!

    great editor…but how do you make the animation play only once? I am trying to move an object vertically and rotate 360 degrees as it moves up.

    What i get is the object moves up then disappears and repeats move up, etc etc

    How do I get it to rotate constantly by 360 continuously as it moves up and continues to rotate but remain at move position?

    when i import editor from the asset store, it completely imports but throws below error:
    Assets/iTweenEditor/iTweenPath.cs(6,14): error CS0101: The namespace `global::’ already contains a definition for `iTweenPath’

    How to solve that?

    • October 9, 2015 at 4:57 pm

      The visual editor has a copy of iTween included since that is a dependency. You have another iTween already in your project. Either delete the version that came with the visual editor or the other version you had installed previously.
