Tween/Easing IN/OUT Behavior

Basically the LiteTween (by Lunnaray) movement behavior.  Something like that to make built-in easing and movements smoother.  Other game engines like UE4 have this built in, I think C3 should as well.

    This is a good idea and we'll probably make an official behavior later down the line. However we'd like to focus on completing the Construct 3 runtime first. In the mean time we will work on the SDK and help third-party developers port their addons to C3.

    Tweening / easing or whatever we will call it would be the best built in the editor itself. So you could tween everything.   For example you can't tween easily "scrollX"  you have to create an object add tween behavior to it and then patch that tweening into a "scrollX" value.   But what if you could to it in events?  something like 
    ScrollX set to tween(start, end, duration, tween type....etc)

    This would be best in expression form like lerp.

    The current LiteTween behavior is very good. If Lunnaray is willing to build a C3 version I'd say this is a low priority. I do feel that tweens are very much a must in game development. There's only so much you can do with lerp.

    So I'm giving this a +1.

    I like the way UE4 handles it with their Timeline node.  Create a movement behavior relative to wherever the object is currently. 

    And yes I agree with Newt I would separately like an Ease() function - but that might be a different idea.

    This is a fair request for a useful behavior. Of course it can be done with events - all of Constructs behaviors can be remade with events. It is something that is commonly needed though: moving an object from point a to point b over a certain duration of time.

    The structure can be similar to the pathfinding behavior without the pathfinding.

    Key elements - Start Point (or trigger), end point, duration, speed, easing

    Ack can't edit these posts.

    Bonus functionality - Applicable to rotations, size, opacity and other transformations.

    The lack of tweening was something that irritated me when I first tried out C2. Both other engines that I use have built in tweening with a few/lot of these easing variants and I'm constantly using that. E.g. for moving Ui elements fluidly or to tween the score variable up to make it more interesting than just increasing it. There are tons of things that I need easing for in my games.

    Like oosyrag pointed out best would be if you could basically tween everything... like opacity, rotation, size, position, variables.

    If drag and drop has it's own behaviour, which is functionally easy to recreate with everyTick, Touch and setPosition; then tweening should as well.


    This gets the full +3 from me.

    I use the javascript plugin for this on a regular basis. Definitely a +3 from me

    Tweens should be functions of the "system object" like lerp(). They would then return a value which could be applied to anything. These should have been there from the start.

    The current LiteTween is an absolute neccesity for me...

    Please i need LiteTween for C3 ... 'cause i use in all my C2 projects!!

    Maybe Scirra should consider buying some of the already developed 3rd party plugins and integrate them as built in addons....?

    Hi Guys

    After Searching i found this for liteTween. I hope it helps

    I would like something where you can do stuff like this:

    1. In your layout you add a timeline object.

    2. One or more sprites can be attached to the timeline object.

    3. For attached sprites, you can add key-frames for on the timeline.

    4. A key frame can contain sprite properties (e.g. position or opacity of sprite)

    5. A timeline have action like: Play, Pause, Rewind, Goto(seconds) and so on.

    6. When a timeline is playing it will change the properties of all attached sprites, according to key-frames value. It will calculate values between key-frames according to an easing (


    I think that would be a really cool feature!

    Just something that might be useful when this (and hopeful a timeline thingy) is going to be implemented.

    Now that Rexrainbow is no longer supporting his plugins, this is an absolute necessity to replace his "Moveto" with an official C3 behavior.

    For mobile, it would be interesting to include a way to boost performance on tweens.

    Instead of calculating the position 60 times a second, I would like to see a way to reduce how often it moves to 1-60 times a second.


    I found some objects can animate 10 times a second and it still appears correctly on screen when animating. I made events for this and mobile performance increased.

    And please add a "stop on collide with solid" checkbox, this is a must have for creating dynamic non-buggy movement for world objects!

    tween plugin is must have for many types of 2d games. 

    i'm using lite tween behaviour too, but seems that its not getting updated anymore.

    I don't agree that Tween plugin can replace MoveTo.

    With MoveTo you have full control of the movement - can set acceleration, deceleration, max speed, change speed while moving, set stop by solids, etc. There is also a bunch of events like "compare speed", "on stopped by solid", "move to distance-angle". All these are impossible or very hard to achieve with tweening, where you can basically only change easing function and duration.

    I hope the Tween behavior can replace all the same functionality available in the MoveTo plugin.
