How to show a label when mouse hover over an sprite?

Question

I want to make an inventory for a character. When the mouse hovering over a slot with an item, its description must be shown.

You can use a TextureRect instead of a Sprite and connect it's mouse_entered- and mouse_exited-signals to show or hide the label respectively:

extends TextureRect

func ready():
    connect("mouse_entered", self, "_on_mouse_entered")
    connect("mouse_exited", self, "_on_mouse_exited")

func _on_mouse_entered():
    $Label.show()

func _on_mouse_exited():
    $Label.hide()

The script above assumes that your label-node is a direct child of the TextureRect, if that's not the case you need to adapt the path to the label-node accordingly.

Attach the following script to your Label:

extends Label

func _process(_delta):
    rect_position = get_global_mouse_position()

I just did on your other question over here.
