DOTween (HOTween v2), a Unity tween engine

Also, have you tried using Restart() instead?

 

It's not that it's not being fired, it's that the code literally tells me that it's incorrect when keeping everything the same and just adding "Forward" to the method. Removing the OnComplete it goes back to working correctly.

Also doesn't like the "oncomplete" on the code.

 

Try reversing the statements

Code (CSharp):

1. .OnComplete(() => { your code }).PlayForward();

 

Hi, i'm tweening a Kinematic Rigidbody2D with DoPath on a 2D path.

I read in unity documentation: "Kinematic Rigidbody 2D is designed to be repositioned explicitly via Rigidbody2D.MovePosition or Rigidbody2D.MoveRotation."

How do i make sure the DoPath tween is tweening it using Rigidbody2D.MovePosition internally?

Thanks.

 

That worked! Thank you, I didn't know the order mattered

 

Most of the methods in DOTween return the Tween so you can chain them, but for some reason PlayForwards and PlayBackwards don't. Not sure why

 

I'm running into some truly bizarre behavior and was wondering if one of yall could offer some help.

Basically, I want to use a Sequence to spawn things at certain times. So, insert a callback to spawn something at, 2 seconds, then another at 5 seconds, and so on. This works great if played like normal, but in my case, I also need to be able to set the time with the built-in. Goto function. However, the frame I begin to do that on the callbacks no longer get called after. Any ideas?

This is a simple example that you can use to replicate the problem I'm running into.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using System;
5. using DG.Tweening;
6.  
7. public class CallbackSequenceTest : MonoBehaviour
8. {
9.     [System.Serializable]
10.     public class MessageObj {
11.         public float Time;
12.         public string Message;
13.     }
14.     public List<MessageObj> Messages = new List<MessageObj>();
15.     Sequence seq;
16.     float startTime = 0;
17.  
18.     // Start is called before the first frame update
19.     void Start()
20.     {
21.         seq = DOTween.Sequence();
22.         foreach (MessageObj message in Messages)
23.             seq.InsertCallback(message.Time, () =>
24.             {
25.                 Debug.Log(message.Message);
26.             });
27.         startTime = Time.time;
28.         Debug.Log(seq.Duration());
29.         seq.Play();
30.     }
31.  
32.     void Update() {
33.         float currentTime = Time.time - startTime;
34.         seq.Goto(currentTime);
35.     }
36. }

Thanks again for any help yall can offer! Maybe I'm just being dumb who knows.

EDIT: So I think the issue is that the time range required for the callback is a specific size cause I realized after changing it to FixedUpdate it now works???

 

If you want the Sequence to continue playing after the Goto command, you have to add an extra parameter:

Code (CSharp):

1. seq.Goto(currentTime, true);

 

Is it possible to combine tweens? I wanna scale and rotate an object simulatenusly

 

Guys, I need an advice - how to smoothly start the object rotation (using ease.inSine) and after rotate it by linear speed for ever until decide to stop?

The standard methods doesn't work here. So, there are 2 ways I know it could work but it doesn't
1. create 2 tweens: 1st tween for rotation start, 2nd tween for infinite loop linear rotation set on 1st tween.OnComplete callback
2. create a sequence, same approach as #1 but without OnComplete callback usage

It doesn't work as expected because 1st part final speed will not ever fit to linear speed if only you will not manually find some reasonable time for 1 circle (360 degrees) rotation. And you will need to do it again just after easing change or any other tween changes.
I also tried to use SetSpeedBased, but 1st part non linear easing doesn't work well there - as a result 1st part rotates much faster comparing to 2nd part.

That's code sample

Code (CSharp):

1. this.transform
2.                 .DORotate(new Vector3(0f, -360f, 0f), 520, RotateMode.WorldAxisAdd)
3.                 .SetEase(Ease.InSine)
4.                 .SetSpeedBased(true)
5.                 .OnComplete(() =>
6.                 {
7.                     // start infinite loop
8.                     this.transform
9.                         .DORotate(new Vector3(0f, -360f, 0f), 520, RotateMode.WorldAxisAdd)
10.                         .SetLoops(-1, LoopType.Restart)
11.                         .SetSpeedBased(true)
12.                         .SetEase(Ease.Linear);
13.                 });

 

That's what a Sequence is for

It's a hack, but my solution would be to use a custom AnimationCurve as the ease for the first tween. I just tried it in the editor and by tweaking the curve's second key to a value of 0.8, the transition seemed pretty smooth.

Code (CSharp):

1. public float speed = 520f;
2.     public AnimationCurve ease;
3.  
4.     void Start()
5.     {
6.         transform
7.                 .DORotate(new Vector3(0f, -360f, 0f), speed, RotateMode.WorldAxisAdd)
8.                 .SetEase(ease)
9.                 .SetSpeedBased(true)
10.                 .OnComplete(() =>
11.                 {
12.                     // start infinite loop
13.                     transform
14.                         .DORotate(new Vector3(0f, -360f, 0f), speed, RotateMode.WorldAxisAdd)
15.                         .SetLoops(-1, LoopType.Restart)
16.                         .SetSpeedBased(true)
17.                         .SetEase(Ease.Linear)
18.                         .Play();
19.                 }).Play();
20.     }

(I have AutoPlay set to false, which is why my code has Play() calls)

 

How I set the loop to dont reset their position to cached start position, instead keep the position set by step complete or something else? I mean, in my mind the folowing code should make the rect transform to go in -135f direction, then reset to new position set in step complete and then going again to position -135, but it reset to original position set when the DoMoveX started

Code (CSharp):

1. rectTransform
2.     .DOMoveX(-135f, durationInScreen, true)
3.     .OnStepComplete(() => rectTransform.anchoredPosition = new Vector2(135f, Random.Range(0f, 35f)))
4.     .SetLoops(-1)
5.     .SetEase(Ease.Linear);

 

You may be able to do this if you call ChangeStartValue() in OnStepComplete()

 

thanks for the answer, a doubt, for being able to call this API I will need to cache the reference to the tween right?

 

Yes I believe so

 

Another question, if I have something like

Code (CSharp):

1.  
2. rectTransform
3.     .DOMoveX(-135f, durationInScreen, true)
4.     .OnStepComplete(() => b.ChangeStartValue(new Vector3(135f, Random.Range(0f, 34f))))
5.     .SetLoops(-1)
6.     .SetEase(Ease.Linear);

is possible to change durationInScreen at runtime? or as this is created at Start I can't change their values during after creation?

 

You use the same ChangeStartValue method - the second parameter is Duration if larger than 0

 

Although In this case you might want to use ChangeEndValue:

 

Getting some error when importing DOTween pro:

Code (CSharp):

1. The type or namespace name 'Core' does not exist in the namespace 'DG.Tweening' (are you missing an assembly reference?)
2. error CS0234: Assets\Plugins\Demigiant\DOTween\Modules\DOTweenModuleAudio.cs(6,19)

 

When doing

Code (CSharp):

1. DOTween.To(DOGetter<float> getter, DOSetter<float> setter, float endValue, float duration)

or any other Shortcut calling DOTween.To, should I do a safeguard before the call if I can expect that the endValue is often already reached? Or is this handled already efficiently inside DOTween.To?

 

You could test this out by adding OnUpdate and OnComplete callbacks and see if they get fired (I'd assume they would). Alternatively, the source code is available:

https://github.com/Demigiant/dotween/tree/develop/_DOTween.Assembly/DOTween

 

Is it a known issue that DOTween does not always behave as it should in the Unity Editor, as it does in an actual build?

 

@Demigiant ?

 

I have a function to tween the XP bar

Code (CSharp):

1. void UpdateBar() {
2.             Debug.LogWarning($"{experienceBar.fillAmount} : {experienceManager.GetNormalizedExperience()}");
3.             experienceBar.DOFillAmount( experienceManager.GetNormalizedExperience(), 1f );
4.             levelText.text = experienceManager.CurrentLevel.ToString();
5.         }

If I call it manually it works just fine but I have it set to be called with an event Invoke.
Doing it this way will call the Debug.LogWarning but not the actual DoFillAmount.

Anyone have any idea why DOTween works fine unless it's a function called via event?

 

Hello!
I have been trying to do some tweening in my buttons, but I have been struggling with some small issues.

This is a reduced version of what I'm trying to do:

• A key is pressed
• A group of buttons within a CanvasGroup should appear but still be a bit transparent
• After three seconds that group of buttons disappears
• If the key is pressed in the middle of the above disappearance, the button should appear again, starting from the alpha left-over from the above point.
• After three seconds that group of buttons disappears

This is a snippet for the code:

Code (CSharp):

1.     private void TriggerTopCanvasSideFadeAway()
2.     {
3.         DOTween.Restart("TopAppear");
4.         topCanvas.DOFade(0.3f, 0.5f).SetId("TopAppear");
5.         DOTween.Restart("TopFade", true);
6.         topCanvas.DOFade(0, 0.5f).SetDelay(3f).SetId("TopFade");
7.     }

The issue that I'm having is that sometimes the row flashes, as it the fading starts from alpha 1 (you can see it towards the end of the gif).

Hi
Is there a way to pause a sequence mid way through, but to ease to a stop rather than halt suddenly?

Thanks

 

Hi guys, quick dumb question that must be simple to do.....

I want my sprite to take ten steps in a grid, and for each step I want to call a method. "updateUnit"

Code (CSharp):

1.         foreach (Location mytile in myPath)  // Step through tiles in path to destination
2.         {
3.             utar = IsoMap.I.MyTilesParent.transform.position + IsoMap.I.MapToScreen(mytile.X, mytile.Y);
4.  
5.             IsoMap.I.Units[CurrentUnit].MyGO.transform.DOMove(utar, 5.5f).OnComplete(UpdateUnit);
6.  
7.             IsoMap.I.Units[CurrentUnit].MyCell = new(mytile.X, mytile.Y);
8.  
9.         }

So instead of what I want, it calls the method ten times after the unit reaches the end of the path, instead of after each DOMove has completed.

What am I doing wrong? How do I get this loop to set up ten tweens, with ten calls to my method after each one completes?

 

Not sure where the best place to post this is, but the custom plugin example is currently a bit broken. In CustomRangePlugin on line #249, the method definition is missing a parameter:

int newStepsTaken

This makes the example not build or run until this parameter is added like so:

Code (CSharp):

1. public override void EvaluateAndApply(NoOptions options, Tween t, bool isRelative, DOGetter<CustomRange> getter, DOSetter<CustomRange> setter, float elapsed, CustomRange startValue, CustomRange changeValue, float duration, bool usingInversePosition, int newStepsTaken, UpdateNotice updateNotice)

 

This example code in the documentation gives an error for the onWaypointChange(MyCallback);

CS1503 Argument 1: cannot convert from "method group" to "int"

Code (CSharp):

1. void Start() {
2.    transform.DOPath(waypoints, 1).OnWaypointChange(MyCallback);
3. }
4. void MyCallback(int waypointIndex) {
5.    Debug.Log("Waypoint index changed to " + waypointIndex);
6. }

 

Hello, I'm using a tween to modify the weight of a post-processing volume. When I'm increasing the weight, it seems to stop or pause before reaching the target value. I have a second one that decrease it to zero, and it seems to be working fine.

For the problematic one, I want the weight to go from 0 to 0.9, and it seems to stop around 0.3, sometimes 0.6, but its very random. I don't have many tweens at all, and I do not have functions controlling all tweens. I have the variables in the inspector, and if I try changing the duration to 2 secs instead of 0.1, it ends even faster.

I added some callbacks for OnComplete, but they are called when the Fade Out (second) tween is called. I'm fairly confused on what's going on.

What are some tips on how to debug this?

Edit: I added some Debug.log that is letting me know whenever I press a key if there are tweens active, paused, and such, and after running the first Tween, it seems it just stays Active and Playing without doing anything or completing (while nothing appears as paused).

Solved: The issue was that when I was opening a menu I was setting the TimeScale to 0 and that was pausing the Tween. I had to make the tween independent of TimeScale.

 

Hi, great plugin love it/used it for years.
Cleaning some cleaning code (that is removing tweens on objects).
Is there a way to get the number of tweens running on a transform ?
Thx

 

Hello, I'm using a DOTweenPath script to run an animation that loops infinitely at some point I want to pause this animation but only after waiting for it to complete it's next step in the animation. How would I do this?

 

I am using DOTweenPath and I am having an issue with were the paths end up being displayed. The game has a prefab that is instantiated and covers the entire screen. On the prefab I have some paths. When the game is run and I display the prefab the paths are not visible. When I go to the scene view to find them they are way off of the screen. I am not using any code at this point. The prefab is instantiated at x=840, y=525 which is center screen but the paths are at negative x=-840, y=-525.

 

Not sure if anyone has asked this before (and I couldn't find an answer when I searched for it), OnComplete gets called for each DOBlendable* function, but is there like a cumulative OnBlendableCompelte sort of a function or something similar?

 

help me I'm doing a tutorial and i am getting the message, "Camera does not contain a definition for DOFieldOfView I do not know what's going on. help

 

I'm trying to create a ScriptableObject that on Awake copies the WPS from the DOTweenPath script on one of my scene objects. I can create my asset and copy the WPS, but my problem is that I want to clear it after I copy it. Calling pathScript.wps.Clear() or pathScript.fullWps.Clear() doesn't work. I don't seem to have access to the same functionality as the "Reset Path" button that the DOTweenPath editor script uses. I'm using the Pro version if that matters. If anyone has a solution I would definitely appreciate it.

 

Can I run a tween inside an async method?
I have an async method that displays a text countdown and would like to pulse the text in some kind of interesting way.
The text is a TextMeshPRO, but I only have the free version of Dotween.
(See code below.)

Thanks. -- Paul

Code (CSharp):

1.   async void CountdownTimerWithMessage(string argMessage, int argCountdownSeconds) {
2.         m_MessageText.text = "";
3.      
4.         for (int secondsRemaining = argCountdownSeconds; secondsRemaining >= 0; secondsRemaining--) {
5.             //
6.             // Use a tween to pulse the message text?
7.             //
8.             m_MessageText.text = argMessage + String.Format("{0:0}", secondsRemaining);
9.             await Task.Delay(1000);
10.         }
11.     }

 

Hello, first time using DOtween pro here.

I want to achieve a sequence for "aquiring weapon"
1- hover the weapon a bit
2- after 0.8 sec hovering, mixing it with flying to a Hand transform

What I want is not play a animation, then next animation. That will feel rigid.
I want some mixing, therefore the hovering is set for 1 sec, and at 0.8 sec the weapon would start flying to hand.

But what happened is hovering > then abruptly jump position > then fly to hand.
Result is position did not mix between 2 tween.
How can I do that? Thank you!

42.             sequence.Restart();
43.             Debug.Log("Play");
44.         }
45.     }

 

Update
I changed the code a bit, and it now smooth.
My only problem now is the moveToTarget is not homing.
That means when target (character hand bone) move, the final destination will be wrong.
How can I implement homing behaviour?

Code (CSharp):

1.     public class Test_DOTween : MonoBehaviour
2.     {
3.        
4.         public Transform target;
5.  
6.         [InspectorButton("Test")]
7.         public bool btn;
8.  
9.         Sequence sequence;
10.  
11.         Vector3 defaultLocalPos;
12.         Quaternion defaultLocalRot;
13.  
14.         private void Start()
15.         {
16.  
17.             //move to target, intend to homing, as target can be a hand bone of character
18.             var moveToTarget =
19.                 DOTween.To(() => transform.position, pos=> transform.position=pos, target.position, 0.35f)
20.                 .SetEase(Ease.InOutBack);
21.  
22.             var hover =
23.                 DOTween.To(() => transform.position, pos => transform.position = pos, transform.parent.TransformPoint(defaultLocalPos) + Vector3.up * 0.5f, 0.5f)
24.                 .SetEase(Ease.InOutQuad).SetLoops(2,LoopType.Yoyo);
25.  
26.             //move up down 0.5 x2 = 1 sec
27.             sequence = DOTween.Sequence()
28.                 //reset
29.                 .OnStart(() => {
30.                     transform.localPosition = defaultLocalPos;
31.                     transform.localRotation= defaultLocalRot;
32.                 })
33.                 //hover a bit
34.                 .Insert(0f,hover)
35.                 //at 0.8 sec we move to target (intend to have some mix to previous movement, because previous stop at 1 not 0.8
36.                 .Insert(0.8f,moveToTarget);
37.            
38.         }
39.  
40.         private void OnEnable()
41.         {
42.             defaultLocalPos = transform.localPosition;
43.             defaultLocalRot = transform.localRotation;
44.         }
45.         void Test() {
46.             sequence.Restart();
47.             Debug.Log("Play");
48.         }
49.     }

 

Played around and used Dotween to do the everything:
* Do the countdown timer.
* Decrement the countdown.
* Display the message.
* Clean-up after itself.

Code (CSharp):

1.                         Sequence textTween = DOTween.Sequence();
2.  
3.                         textTween.Append(m_FadingScreen.DOFade(1f, 0f)).
4.                             InsertCallback(0, () => {
5.                                 m_MessageText.text = "Battle begins in: " + countdown--;
6.                             }).
7.                             Append(m_FadingScreen.DOFade(0f, 1f)).SetLoops(m_BattleModeRequestCountdown + 1).
8.                             OnComplete(() => {
9.                                 m_FadingScreen.alpha = 0.0f;
10.                                 m_MessageText.text = "";
11.                             });
12.  
13.                         textTween.Play();
14.  

 

FIXED:
Adding DOColorChar() with Join() as the last command in the sequence works.



Having trouble getting the <animator>.DOColorChar() command to work - the color doesn't change at all.
All the other animator-specific functions I've tried work fine.
If I use <TMP>.DOColor(), that works to change the color of the entire text but, that's not what I'm after.

It has something to do with other char animation tweens.
If I use DOColorChar() on a charactoer that is not being tweened in other ways it works.

Tweens I'm using: DOFadeChar(), DOPunchCharScale


Thanks.

Hi. I have some errors in playing Dotween Exmples. I downloded DOTween examples form this site. bout some errors happened.

error1:

please help.

 

I haven't heard any response since this post from almost 2 months ago.
@Demigiant if you're no longer offering support for this asset you need to update your Asset Store page to state so.

 

I was using DoTween without problems. I bought the pro version but i keep getting errors during import. I created a new project and imported dotweenpro fresh and the same issues occur. Please help, this is driving me crazy!

also burst seems to be stuck?


I have tried with just TextMesh Pro and same issue persist.

 

Hey! I need to tween anchored position of a rect transform but I can't find any function for that. Any help?

 

There is a DoAnchorPos() method and many other RectTransform shortcuts, but you need to make sure you have the UI module installed. (Tools/DemiGiant/DoTween Utility Panel -> Setup DOTween)

 

Its not showing up for me.

 

How can I debug this error I see in my live app in GameAnalytics in the quality section?

Max Tweens reached: capacity has automatically been increased from 200/20 to 500/20.

The problem I encounter is that neither in unity editor nor on device I can reproduce the error. And when I look at the active tweens while in play mode I don’t see any adding up. They all get killed when they need to be killed.

Any ideas on how to move forward?

 

Adding to the above, I tried to use DOTween.TotalPlayingTweens(); and DOTween.TotalActiveTweens(); they both show the exact same thing as the DOTween component on the [DOTween] gameobject. I have maximum 12 tweens running at the same time in my game and I kill them all after using. My initial setup is the default for 200 TW, 20 SE and I never should get even close to the full capacity of the pool.

Is there some kind of hidden count that adds up to those 200 that I can't see?

Or might this be a race condition which I can't reproduce on my computer or my phone? I'm thinking for example in level specific tweens that I kill before I destroy the level prefab. Maybe on low end devices it can't kill them all before it gets destroyed? But if this is the case, wouldn't I get as well a warning about the game trying to access tweens that are not existing anymore?

Completely lost on this one. Any help is appreciated.

 

It's not only the amount of tweens currently playing that will increase the capacity.

Are you setting up tweens in Start() or Awake() and then running them at some point later on? If so, those tweens are like any other object that gets created and stored for later use.

But it's not an error. It's just a message letting you know that the capacity has been increased. It's possible to increase the default capacity manually. Are you having performance issues? If not, probably nothing to worry about.
