Which stage size is good for project that opens in maximized window?

[WAYLIVES]

640 x 360 (16x9)
But I usually do: 640 x 400 (8x5)

[qwertytytytytyt]

how to remove these back lines on the sides?

[WAYLIVES]

If you don't want to see black bars, then choose the latter option: "Dynamically resize size to ..."

[qwertytytytytyt]

this reduces the sprite sizes too much, are there no other methods?

[WAYLIVES]

No

this reduces the sprite sizes too much, are there no other methods?

maybe by using a camera extension (like Camera V2) to zoom in based on the stage size, fixing the "actual stage size" in place in one axis? though this wouldn't work for anything overlayed over the stage, like monitors
(if Window Controls had a block to get the actual visible area of the window, aka window.innerWidth/Height, this would be way easier)

Made this a while ago for someone else, basically changes the aspect ratio of the stage. This will break most projects, you'll have to patch them

Thank you! It worked!

[qwertytytytytyt]

it can break project? you mean if project is already done and i add this sprite something can go wrong in it?

[qwertytytytytyt]

bro it still has very very small line on sides, how to remove it by using the same blocks?

[snowboyz0825]

if I had to guess that's because of rounding, though I've never had the same issue. Just mess around with it, maybe add one to width

[qwertytytytytyt]

Add one to 640 or to 2?
