Scissors are set to 0000 ;

the graphics still don't start at the very left & very top of the window - rather like + ~ 5 pixels

on the right and bottom side, however, they close exactly with the window borders

The reason seems to be SetWindowAllowResize( 1 )

If this is active the lines dont align to the very left and top


SetWindowAllowResize( 1 )
SetWindowSize( 1024, 768, 0 )
SetVirtualResolution( 1024, 768 )
SetScissor( 0,0,0,0 )

Do

drawline(1,1,1024,1,255,255,0)
drawline(1,1,1,768,255,255,0)
sync()

Loop

======

Without SetWindowAllowResize it works fine, line direct at left and top


SetWindowSize( 1024, 768, 0 )
SetVirtualResolution( 1024, 768 )
SetScissor( 0,0,0,0 )

Do

drawline(1,1,1024,1,255,255,0)
drawline(1,1,1,768,255,255,0)
sync()

Loop


Seems to be a bug in SetWindowAllowResize( )

the VirtualResolution size is constant if a window resize.
see commands
GetScreenBoundsBottom ()
GetScreenBoundsLeft ()
GetScreenBoundsRight ()
GetScreenBoundsTop ()

It has nothing to do with Virtual Resolution -> it works fine, even if Virtual Resolution is set

It is, because SetWindowAllowResize( ) is buggy.

Witout this command, everything works well.

u used both the same size
SetWindowSize( 1024, 768, 0 )
SetVirtualResolution( 1024, 768 )
if your window get 16:9 it will show 4:3 inside.

but i remember if the windows changed maximized and get back to normal it get a different size.

if you set full screen here it ignore the size x,y and used the desktop size
SetWindowSize

If I run your code, there are ~ 5 pixels black borders at the top and the left.

Remove the " SetWindowAllowResize( 1 ) " line from your code and restart - then it will start properly from the beginning.

So there must be a bug in the "SetWindowAllowResize" command.

This makes the distance between 1,1 and the border even bigger at my window -

without the SetWindowAllowResize() it works well - i think it needs to be fixed

I just tested on my machine. Works fine here too (although I just realised I'm still on 2017.02.21). Maybe Paul will have a look if he's got everything he needs. Let him know what version Windows and AppGameKit you are using etc.

Yeah, looks like a bug, although not as described in the OP. I've replaced your prints with text so it doesn't resize with the change in virtual res (which was confusing things). Now it is clear to see what is happening. The very first resize of the window appears to shrink the window by 10 pixels in the width and height. Looks to me like upon resize, the GetDeviceWidth/Height is deducting the width of the window border from the result perhaps? All subsequent resizes work fine.

You can fix that by inserting a setwindowsize(width+10, 768+10, 0) before the setvirtualresolution if you want to force a fixed height.
you are right though; the whole resize/getdevicewidth/height/setwindowsize/setvirtualresolution thing needs to be synchronized

i don't think that is what he's talking about though

Yes (built on 2017-02-27) // Windows 10

When i change the setwindowsize to SetWindowSize( 1024, 768, 1 ) (Fullscreen) or when i maximize my window i get the results you speak about.
The reason is my display resolution is 1920x1080 which is an aspect of about 1.777 where as 1024x768 is an aspect of 1.33333
AGK will clip the screen to try to display the aspect you request. That is why it is shifting your graphics to the right.
you can still access these areas by using negative x and y values and setscissor(0,0,0,0). you can also get the x/y values of the right/left/top/bottom of your window
using the GetScreenBounds commands

Thanks, fixed for the next version. It appears Windows changes the window title bar style when it is allowed/not allowed to be resized, which changes the window resolution. We'll use a different method to restrict resizing for the next version.

I had the same problem too regarding sprites at 0,0 on Android.
If I SetImmersiveMode(1)
and then SetVirtualResolution( getdevicewidth(),getdeviceheight() )
and then SetOrientationAllowed( 0,0,1,0 ) (to force horizontal orientation)
The sprites thats positioned at 0,0 will be shifted to the right by a few pixels.

The problem would not occur when I specify the SetVirtualResolution with real number, such as
SetVirtualResolution( 1920,1080 )

Will post a proper bug thread with example project later

It might be that getdevicewidth/height are not updated immediately. The OS takes some time to activate immersive mode so you may have to poll those commands and adjust the virtual resolution when they change.

I waited for the device orientation to change to horizontal with WHILE/ENDWHILE until screen width>length.
After that, I update the sprite position to 0,0 in every frame in the main loop.
But still the 0,0 sprite will get shifted
