Hi.
First of all, thank you for this interesting tutorial. I watched the video of making your door and key in Godot and I did exactly the same things, but the problem is that when Steve picks up the key and presses the up key, it moves to the second place wherever it is in the game. That is, it is not yet transferred to the CollisionShape2D range. I couldn't run your game to see if you had the same problem.
Please help me.
Thank you
