Invalid operands 'Vector2i' and 'Callable' in operator '<'

[lavish raven]

Hi, total noob here.

I'm trying to make a script that, when you push a button, the window gets bigger to fit your screen and then enters fullscreen.
When I try pushing the button, the instance immediately stops responding and I get the error message aforementioned in the title.

func _pressed() -> void:
    print("Button clicked")
    var paranoiaZoom = Vector2(DisplayServer.window_get_size())
    while(paranoiaZoom < DisplayServer.screen_get_size):
        paranoiaZoom = paranoiaZoom*2
        DisplayServer.window_set_size(paranoiaZoom)
    DisplayServer.window_set_mode(DisplayServer.WINDOW_MODE_FULLSCREEN)```

`while(paranoiaZoom < DisplayServer.screen_get_size):` seems to return the error.

I have no prior knowledge of GDscript or C#/C++ or anything, and no clue what I'm doing

Your while loop is trying to compare a vector with a function, not the output of it. Is the rough translation of your error.

You need brackets after DisplayServer.screen_get_size
This asks the function to actually run

[lavish raven]

Ah

I added the Vector2 part to the var paranoiaZoom =… line after I got the error, was that necessary or should I change it back

[silk axle]

Not needed, that method already returns a vector2
What you are doing there is telling it 'this vector must be a vector'...which isn't really that useful 😄 (although admittedly, not harmful either, especially if you can't be sure)

That worked

Is there some sort of wait function? The animation I'm trying to do isn't happening and I'm pretty sure it's due to it happening all at once or something

I can't seem to find it

[silk axle]

what are you trying to do, and how are you currently trying to do it?

[lavish raven]

I want the window to exponentially get bigger, and then go into fullscreen

right now it's just going into fullscreen immediately

when I unfullscreen it, the window is the bigger size, though

[lavish raven]

script up here is pretty much unchanged besides the fix for the error

[silk axle]

how big are you starting the window?

[lavish raven]

however big it is by default

[silk axle]

so the issue is probably that it starts so big one loop is making it max size

[lavish raven]

well even if I make it smaller it does the same thing

[silk axle]

try turning the 2 down to something smaller

[lavish raven]

I changed it to 1.1 and now I got an error

Invalid operands 'Vector2' and 'Vector2i' in operator '<'.

from the line
DisplayServer.window_set_size(paranoiaZoom)
it seems like?

[silk axle]

I should've expected that, it hough it might play nice, but no
surround the DisplayServer.screen_get_size()
with a new Vector2() like:
Vector2(DisplayServer.screen_get_size())
this will 'cast' the vector to a float version, meanig it now can deal with this comparison
(or do 'Vector2i()' around your paranoiazoom)

[lavish raven]

In the while line?

[silk axle]

yes

a cast when done like this essentially tells godot to pretend those numbers are a different type until its done (its a bit fancier in the real process, but not by too much)

[silk axle]

oh....i see

do the same cast on the intial setting, and know that now we've dont it twice theres almost certainly a better option 🙂

[lavish raven]

im sorry I read that and it did not make sense in my brain

[silk axle]

var paranoiaZoom = Vector2(DisplayServer.window_get_size())
like you had to begin with....you;d solved a problem you didnt have yet 😛

[lavish raven]

so I should put the Vector2 for the definition of the variable?

[silk axle]

yes

[lavish raven]

should I remove the Vector2 from the '<' expression or no
