Condition "!is_inside_tree()" is true. Returned: false

Question

Hello, I am creating a room like the binding of Isaac

calldeferred(removechild, ...) and calldeferred(addchild, ...) to change the room every time the door is opened.

But even if I check the remote, there is nothing wrong, but this error pops up in the debugger.

[Condition "!isinsidetree()" is true. Returned: false]

I wrote the above mechanism by loading the instance stored in the Level1 scene room array from Door.gd.

Sorry to my awful English, Thank you.

Hi,
this looks like you are doing something with the object before it is in the tree.

If you create an instance and add it via add_child you have to wait unitl it signals "ready" to actually be sure it is initialized correctly.

signal "Ready"!

I wasn't thinking about the signal in the first place. Thank you!
