How do you make one node follow the position of a node from another scene?
xyz That's just how the code is called. "bottom_checker" is the Area2D. It's connected with the "body_entered" signal.
When the enemy/object enters the Area2D body, that's when the code to have the enemy node (body) move in to the container node ($EnemyContainer) and stay there is called. That's what I'm trying to figure out.
It's not the Area2D that's the problem (I think). When it makes contact with the enemy, the code is called, but it's the code in my function that I'm struggling with.
I apologize if I'm not communicating myself well.

xyz Hey! It worked! "body.reparent($EnemyContainer)". Thanks, @xyz. You always save the day. 
Thanks for being patient and taking the time to help. Your time is appreciated. I didn't even know about the re-parent method.
Edit: Just one more thing. The enemy moves into the container, but not the center. It depends on where you jumped on it. I'll keep doing my own research and brainstorming to see if I can solve it myself, but if anyone has any extra ideas, I'd be grateful. Thanks again.

xyz Hmm. I put "body.position = Vector2(0, 0)", after the reparent line of code, but that made it fall through the floor again. If I use global_position, the enemy just disappears.
I also get an error for the reparenting line: E 0:00:01:0689 Player.gd:86 @ _on_bottom_checker_body_entered(): "Can't change this state while flushing queries. Use call_deferred() or set_deferred() to change monitoring state instead."
I've decided that rearranging the node hierarchy is not an effective way of achieving the result I want.
I'd like the body to consistently follow the center of the EnemyContainer node.
When I use "body.set_deferred("global_position", EnemyContainer.global_position)" the body teleports to the initial global_position of the EnemyContainer, but then it stays there, instead of following the EnemyContainer node which rises above the player (its parent)
It works if I reparent the body to the EnemyContainer, but I get the concerning error: E 0:00:02:0592 Player.gd:86 @ _on_bottom_checker_body_entered(): Can't change this state while flushing queries. Use call_deferred() or set_deferred() to change monitoring state instead.
<C++ Error> Condition "body->get_space() && flushing_queries" is true.
<C++ Source> servers/physics_2d/godot_physics_server_2d.cpp:654 @ body_set_shape_disabled()
<Stack Trace> Player.gd:86 @ _on_bottom_checker_body_entered()
I just want the body node to follow the position of the EnemyContainer node's center, so I don't have to "unparent" the body when it is thrown and separated from the EnemyContainer node and its position (a later function I intend to implement).

NJL64 Add a boolean flag property to the enemy script, name it something like carried. Set this flag to true when the enemy needs to be carried and set it to false when it doesn't. Test this flag each frame and if it's true set enemy's global position to container's global position as discussed earlier.
xyz That makes sense.
Is there a way I can put this positioning code in _physics_process()?, because I get the "'body' not declared in current scope'" error, and I'm not sure how to define body in in the _physics_process() function.
(I use body so that whatever body enters the bottom_checker can follow the same code, instead of the enemy scene exclusively. So I want to access the body rather the enemy scene.)
xyz So you're saying you want me to write the positioning code in the physics process of the enemy script instead of the player script?
That would mean I would have to write positioning code for each individual object/node script, rather than having the player script position whatever body enters it's Area2D node (bottom_checker).
Sorry, if I'm getting this wrong.
