I'm still learning Godot, and I'm trying to create some sort of post-it board, with moveable and writeable post-its, etc.
I've been doing some researches, and I found this reddit post, with non-conclusive answers, which deals about kind of the same problem as I'm facing now.
I have set a button to spawn new post-its, and I want to check for objects overlapping with the newly instanced post-it, and if it is overlapping, I want to move it a little.
I use Area2D as root nodes of my post-it instances.
However, it seems that
get_overlapping_areas() can't be called before a certain time, and is then not really useful for me. If I check this function when instancing the post-it, it returns a blank array, even if it overlaps. Same if I check it during its
_ready() function. It only returns overlapping areas if I call it after its instantiation, through a button or a timer. However, I'm reluctant at the idea of setting a timer for obvious reasons, and using a button is also not a great idea, because of the need of user input. In the reddit post, another solution proposed was to set a function checking every child of the main node, but I'm not happy with it because it will take much longer with a great number of post-it.
I hope a better solution exists to do what I want, and I hope you can help me! Maybe I'm just missing something, or approaching the problem from the wrong direction.
