Hi,
I have a 2D tilemap with a player character. The player character has a camera attached which follows his movement.

I want to display a map node above the player sprite when the hotkey is pressed (centered in the camera).

The problem is I can’t calculate the correct centered position inside the camera.

When I try to center it by using visible rect of camera viewport, I get some fixed position that doesn’t change once the player has moved. Here’s the code:

map_pos.x = get_node("Camera2D").get_viewport().get_visible_rect().size.x - map.get_node("Panel").get_size().x

map_pos.y = get_node("Camera2D").get_viewport().get_visible_rect().size.y - map.get_node("Panel").get_size().y

How can I calculate the center coordinates of the camera viewport, and put something in them?

Thanks.

Just to clarify - what I need is to calculate the coordinates inside the viewport and then transform them to global coordinates so that the node ends up in the center of viewport.

OK,
My mistake was adding the new node under root, and not under Camera2D. The final code looks like this:

map = load("res://scenes/map/map.tscn").instance()

Then:

get_node(“Camera2D”).add_child(map)

Then:

var map_pos = Vector2()

map_pos.x = get_node("Camera2D").get_viewport().get_visible_rect().size.width/2 - map.get_node("Panel").get_size().width/2

map_pos.y = get_node("Camera2D").get_viewport().get_visible_rect().size.height/2 - map.get_node("Panel").get_size().height/2
map.set_pos(Vector2(map_pos))
