Post subject:  blting to the screen for x seconds
I'm trying to make it so in my game it will blt the screen black for a second or 2 in game. Currently however the blting last what is a like a mili second. I've tried to just get the game to keep blting to the screen until the loops broken by gettickcount but with no such luck.


Do Until x = True 'infinite loop
DD_BackBuffer.SetFillColor RGB(0, 0, 0)
Call DD_BackBuffer.DrawBox(0, 0, (MAX_MAPX + 1) * PIC_X, (MAX_MAPY + 1) * PIC_Y)

If GetTickCount > tint + 2000 Then ' breaks the loop after 2 seconds
tint = GetTickCount
Exit Do
End If
Loop

any help on the matter would be great

thanks

don't have a loop inside the main loop, just have a check each time the normal loop passes through.

Code:
If BlckScrnTimer <= GetTickCount
    DD_BackBuffer.SetFillColor RGB(0, 0, 0)
    Call DD_BackBuffer.DrawBox(0, 0, (MAX_MAPX + 1) * PIC_X, (MAX_MAPY + 1) * PIC_Y)
End If


And then if you want to start the blackscreen:

Code:
BlckScrnTimer = GetTickCount + 2000 ' Two seconds.


Hope this helps.

Instead, make it not call the Render_Graphics sub, which will stop drawing everything and only show black...which would have the same effect but better. So:

Code:
Public tmrStop As Long

.........

If tmrStop < GetTickCount Then Render_Graphics


Then where you want to make everything black, enter this code:

Code:
tmrStop = GetTickCount + 2000


And that will make everything black for 2 seconds.
