"Tween" behavior should be enabled as default for every object

This is just a quick question. Will adding “tween” behavior to a lot of objects affect game performance? If not, then why it’s not added to objects by default? I think we can all agree that it’s one of the most used and tested behaviors/extensions that are not added to objects by default and I think it could be upgraded to default object behaviors.

On a side note, this behaviors/external extension system is confusing to me. The tween, for example, is not shown in external extensions list but it can only be used for manipulating a scene value, so it doesn’t need to be an object behavior. So tween as the external extension is enabled by default and tween as object behavior is optional?

Yes, it will. Just from the object list building needed alone. a lot of performance? That depends, but it will impact it, yes.

Tween is not an external extension, or an extension at all. It’s a native behavior in the engine.
