For design reasons, I have to get the center of the current camera without getting a reference to its node (not known at advance).
Si I tried this:
var camera = get_viewport().get_camera()
But it returns
So I tried something else, like this:
var vtrans = get_viewport_transform()
var top_left = -vtrans.get_origin() / vtrans.get_scale()
# Then, to get the center, add half the size of the visible area?
var vsize = get_viewport_rect().size
var cam_pos = top_left + 0.5*vsize/vtrans.get_scale()
Well... works fine, as long as I don't resize the window. If I do, it produces an offset.
And it happens because
get_viewport_rect().size is not the actual size in pixels of the screen, but a fixed value.
I can't use
OS.get_window_size() either, because it doesn't takes display options into account.
So at this point, I could eventually recompute the size with all possible display options, but... is there something simpler than that?
Any idea how to get the center of the current camera without knowing where it is in the scene tree?
