| I have a problem with this code i want to scroll only PART of the screen XYWH as in 100,100,200,200 so I set the SetViewPort to those specs; then my updates are within that field OK! it works ... or so i thought! except i noticed that after the viewport has been set, I cant animate elsewhere on the screen. so i thought the soilution was to add another / a second setviewport after my "drawing", a setviewport() that "normalised" the viewport to 0,0,640,480, but it doesnt seem to work; here is my code: While Not KeyHit(KEY_ESCAPE) Cls Do-something() Do-something() … … SetViewport(100,100,200,200) ‘only do something is specific area! .. … Flip 0; Wend I tried putting a SetViewPort(0,0,640,480) just before flip 0; but it did not seem to work! all "future" drawings are only done is the tiny area?? |

| Don't want to appear too negative but couldn't you post a simplified but runnable version of the code you're having trouble with. <edit> Maybe this :
Graphics 640 , 480
Local image1:TImage=LoadImage("max.png")
While Not KeyHit(KEY_ESCAPE)
Cls
SetViewport x1 , 100 , 200,200
DrawImage image1 , x2 , 0
x1 = (x1 + 4) Mod 640
'x2=x1 'uncomment to see a different effect.
SetViewport(0 , 0 , 640 , 480)
DrawImage image1,200,0
Flip
Wend
? You might also want to check the setorigin command. |

| Well I would say that its because all your drawing commands are after you set the veiwpoint back to the small one |
