I'm using AppGameKit 1088b on Windows 7 and coming across an annoyance / potential game issue.
I've set up a simple test for a scrolling sprite background and it is a bit jittery in Win7. The movement is smooth for a few seconds then jittery, then repeats.
This doesn't occur on my Nexus 7 (android 4.1) or my HTC Incredible 2 (android 2.3). Just my Windows machine which is pretty high end.
Is it some sort of rounding issue?
Could others test this on their Windows 7 machines and tell me if they have the same results? Project files attached.
Thanks!!
SetDisplayAspect(4.0/3.0)
SetOrientationAllowed (0,0,1,1)
background_image = LoadImage("scene.jpg")
background_sprite = CreateSprite(background_image)
SetSpriteSize(background_sprite,-1,100)
SetImageWrapU(background_image,1)
AddVirtualJoystick(1,10,90,10)
u# = 0.0
do
x# = GetVirtualJoystickX(1)
u# = u# +x#/1000
SetSpriteUVOffset(background_sprite,u#,0.0)
Sync()
loop
END
EDIT: Some further notes / testing. I think that it is the new Catalyst drivers... I can't load the ATI Control Center app to change settings... seems to be a constant issue with ATI.
When I run the app fullscreen it definitely looks like a vsync issue. When I run it in a maximized window there's no issues, in the normal size window it is jittery, but doesn't look like vsync issues, though it could be... I'd still appreciate some others testing it if possible.
Now I notice if I have Adobe Reader minimized the windowed version is fine..but fullscreen still has vsync issues.
Thanks again!
