Tween "polygon" property of Polygon2D object

[Halfmania33]

Hi everyone,

i want to submit a request to add the possibility to tween the polygon property of a Polygon2D object.
It would allow to make various interesting effect like morphing a shape into another one smoothly (of course using the same amount of vertices).
Right now, we have to use convoluted ways to do it.
Allowing to do it through Tween would be so great and make things so easy.

Hopfully someone could implment it.

The polygon property is an array of points, so you cannot tween the entirety of the array at once. You need to adjust individual points' position using a script instead.

That is, unless Tweens inherently supported tweening Packed*Arrays, but that would be its own can of worms.

I think it's even more complex than that, because these are pool arrays, which makes them copy on write. In order to interpolate the array the tween should also have a notion to reassign it. Imo it's better done with a cus5om script.

Thanks for your reply.
I think adjusting individual points position using script is too tedious for the result i try to achieve.
I really think adding the possibility to tween an array of points (even a limited size array) is the best solution.
The problem is i'm not an expert developper, so it's difficult for me to imagine the amount of work to implement this feature.
But i really think it's worth it.

See godotengine/godot#66771, by the way.
