How expensive usage of 'Tween' is

Godot Version

Godot 3.5.3.stable.mono

Question

Im thinking of using it for FPS camera animations, for example when player shoots so camera will be pushed somehow on every shot. So im curious about how expensive will it be in terms of performance to create tween on every weapon shot.

You could reuse a tween. 3.x even has a node for tween, so you only need to call start() again.

I mean yes, but i will need to create them dynamically because there could be multiple shots animation at the same time.
