Hi everybody!

I was sure that SetSpritePosition (SpriteNumber, 0, 0) should put my sprite in top left corner of the app's window no matter what.
But it looks like it's true only when the screen size's aspect is 4:3 (e/g 1024 / 768).
It other cases the sprite is moved some distance towards the center along X axis.
Here are some code examples and screens:

With 4:3 screen

With some other aspect

So am I doing something wrong? Or do o,o coordinates not always mean the top left corner in percentage system?

SetVirtualResolution (actual_windowsize_width, actual_windowsize_height)

Yeah, but SetVirtualResolution turns off the percentage system, doesn't it?

I'm seeing the call to SetDisplayAspect. This will turn on percentage. So set something like SetDisplayAspect(1920.0/1080.0) and see if that works

Thanks!
SetDisplayAspect being set to the same values as SetWindowSize seems to do the trick on a desktop/laptop.

You can also use SetScissor(0,0,0,0), which allows u to use negative coords to position stuff to the left of zero, and values over 100 to position them to the right.

This is handy as it keeps the aspect ratio the same, so your game doesn't stretch when running on devices with different aspects.

AGK has commands to return the exact values of the left and right hand edges of the screen, but I forget what they are and I'm not at a PC right now.
