After some prompting from Anawiki Games to fix my code to run on lo-res netbooks I did this which I thought I'd share:
For example on a 1024x768 system it will use that for full-screen but only 800x600 for windowed mode. For a netbook that is 800x600 it should use 800x600 for full and 640x480 for windowed. There's no aspect ratio correction, but I don't care about that just yet, maybe for a later game. I just needed to fix this resolution crash issue first.
Basically ScreenWidth/Height is my desired size that all my code is based on, and WindowWidth/Height is the best fit.
Here's some code snippets for you to use if they prove helpful:
'Detect best Window Size
DebugInt = 11301
Const MAX_RESOLUTIONS:Int = 3
Local ResolutionX:Int[MAX_RESOLUTIONS]
Local ResolutionY:Int[MAX_RESOLUTIONS]
ResolutionX[0] = 640
ResolutionY[0] = 480
ResolutionX[1] = 800
ResolutionY[1] = 600
ResolutionX[2] = 1024
ResolutionY[2] = 768
WindowWidth = ScreenWidth
WindowHeight = ScreenHeight
'Loop back through resolutions until we get one that fits.
Local resToTest:Int = MAX_RESOLUTIONS - 1
Local found:Int = 1
Local comparisonHeight:Int = DesktopHeight
'For Windowed mode we need to take into account the Window title bar, so reduce the comparisonHeight by a big title bar height.
If FullScreen = 0 Then
comparisonHeight:-30
EndIf
While comparisonHeight < WindowHeight
'Did we fail?
If resToTest < 0 Then
found = 0
Exit
EndIf
DebugInt = 11302
WindowWidth = ResolutionX[resToTest]
WindowHeight = ResolutionY[resToTest]
resToTest:-1
Wend
DebugInt = 11303
If found = 0
DebugInt = 11304
RuntimeError "Cannot find a suitable resolution. Desktop Resolution= " + DesktopWidth + "x" + DesktopHeight;End
Depth = -1 'failed
End If
Method DoSetVirtualResolution()
If ScreenWidth <> WindowWidth Then
SetVirtualResolution(ScreenWidth, ScreenHeight)
VirtualRatioX = ScreenWidth / Float(WindowWidth)
VirtualRatioY = ScreenHeight / Float(WindowHeight)
UsingVirtualResolution = 1
End If
End Method
With this any many other recent changes, my framework is now quite enhanced since the version I sold to BFG, muhahaha.
