Tweening using dots

Is there any ready solution or at least recommendations on how do deal with tweening.

I'm talking about both sequential or parallel changes to component values of an entity,
something similar to http://dotween.demigiant.com/ but using pure data-oriented approach.

Imagine a box that has to move up by 100pixels within 500ms then rotate 180degrees within 250ms, and then move down seme 100px/500ms and then get destroyed.

In OOP way it can be done using coroutines, but what about ECS?

 

I am not sure why would you use coorutines for such basics task in OOP.

But in DOTS you mainly operate on entities. There were multiple solutions on the forum. Myself I did mapping to NativeArrays and was able to control Game Objects from ECS systems. That was mainly because of PhysX.

What is your application for OOP, that you require Tweening?

 

I DO NOT need to control Game Objects from ECS systems... I'm talking about pure ECS.

I need to be able to define a sequence of changes to an entity (each change happen smoothly over time) and then playback that sequence, and also I need to handle the sequence end.

 

I was intending to work on this with my prototype (pretty unique) tweening solution I wrote a couple of months ago but I haven't had a chance unfortunately. Maybe I'll see if I can find some time next week.

BTW my solution is fake component inheritance similar to unity physics allowing different tween components to exist in the same buffer.

 

There are these you might be able to try out. I have not tried them myself, but they are ones I came across. The second one I believe is supposed to work with pure ecs but also gameobjects.

This solution is fine and will work for most people however, it does not do what SubPixelPerfect is asking (chaining them back to back). Also there are a few other limitations I've discussed here.

Oh nice. The solution you came up with sounds pretty good. I hope you do get around to putting it out there some time.

 

Thank you @MostHated PlasticTween looks like a good point to start, and it will work for many cases
@tertle Yes most tricky part here is sequencing, looking forward to hearing some news on your solution.
