Zylann, actually, it's because of using a signal that I needed to find the player.
I want to make the player and the item interact - when the player (body) enters the item (area) - so I use a signal. (And for my logic I need to know the item position in the signal method, which I pass a extra parameter.)
So I created a script for the item, where I
connect() it with the player.
And I don't want to have the player path harcoded there.
If you know a better way to organize this, I am open to know :)
