Is it possible to create an object at a childObject's worldposition and attach the childObject to it

Is it possible to create an object at a childObject's worldposition and attach the childObject to it? Then, the childObject's local position sholud be set to 0 because it is the child of an object that is in the same place.

 

Yes.

 

Not entirely sure that is what you want since your question is unclear, but prefix this with "In Unity: " and even free ChatGPT gives you code and explanation you can tinker with.
Experiment with some cubes to understand what happens and how localPosition and regular "position" work.

transform.position, returns world position of an object. transform.rotation, returns rotation. Those are in the world space. You can pass them into instantiate, or set them on newly constructed object, then parent. Or you can parent then zero local transforms...

 

Yep. Simplest and trivial way is to attach object to parent, set local transforms to 0.
Or optionally, set object transforms, as other object, withouth parenting.

You can also attach to parent, set local position and detach from parent, if you are not familiar yet with transforms manipulations.

 

I understand that yes, I recommend you look for tutorial videos on YouTube, you will almost always find very good information there
