ScreenModeExist

Status = ScreenModeExist(Width, Height, Depth)

Parameters:     Width = The required screen Width you wish to query     Height = The required screen Height you wish to query     Depth = The required screen Depth you wish to query (16bit ,24bit or 32bit)

Returns:     Status = If you computer has the requested screen mode, it's return a true(1) if not it'll be False(0)

The ScreenModeExist functions checks what full screen modes your computers display device supports. When developing your game, it's very important not to make assumptions about the type of display that the players your game might have. As such, it's a good habit to check if a screen mode exists before attempting to open the screen of that size.       Valid Depths            16 = 16bit            24 = 24 bit            32 = 32bit FACTS:       * ScreenModeExist checks a full Screen display mode is available, it's not required if your using a windowed screen mode for your program. Mini Tutorial:       This example checks if your video cards supports certain full screen display modes.    ; Check What 320*240 modes your video card supports   For Depth= 16 To 32 Step 8      Show_Info_AboutMode(320,240,depth)   Next   Print ""    ; Check What 640*480 modes your video card supports   For Depth= 16 To 32 Step 8      Show_Info_AboutMode(640,480,depth)   Next   Print ""       ; Check What 800*600 modes your video card supports   For Depth= 16 To 32 Step 8      Show_Info_AboutMode(800,600,depth)   Next   Print ""    ; Check What 1024*768 modes your video card supports   For Depth= 16 To 32 Step 8      Show_Info_AboutMode(1024,768,depth)   Next    ; Show the Screen to the user and wait for a key press before ending   Sync   WaitKey          Function  Show_Info_AboutMode(width,height,depth)    ; Check if your video card has this Full Screen mode ?   If ScreenModeExist(Width,Height,Depth)=true    ; if it does, then set this string variable to "Available"      Exists$="Available"   Else    ; if it doesn't, then set this string variable to "Not Supported"      Exists$="Not Supported"   EndIf    ; Converted the screen width/height/depth into a string for display   s$=Str$(width)+"x by "+Str$(height)+"y "+Str$(Depth)+"Bit ="    ; Display this screen mode size and whether it exists or not   Print "Full Screen Mode:"+s$+Exists$ EndFunction    On my computer, This example would output. Remember, not every computer has the same display modes.      Full Screen Mode:320x by 240y 16Bit =Available   Full Screen Mode:320x by 240y 24Bit =Not Supported   Full Screen Mode:320x by 240y 32Bit =Available      Full Screen Mode:640x by 480y 16Bit =Available   Full Screen Mode:640x by 480y 24Bit =Not Supported   Full Screen Mode:640x by 480y 32Bit =Available      Full Screen Mode:800x by 600y 16Bit =Available   Full Screen Mode:800x by 600y 24Bit =Not Supported   Full Screen Mode:800x by 600y 32Bit =Available      Full Screen Mode:1024x by 768y 16Bit =Available   Full Screen Mode:1024x by 768y 24Bit =Not Supported   Full Screen Mode:1024x by 768y 32Bit =Available
