Scroll really slow

How I would like any advise or comments on this...I am trying make an image scroll really slow. Here is my code:

scroll% = scroll% + 1 (this is very smooth but too fast)
scroll% = scroll% + 0.5 (this is not smooth but very slow)

anyone have any ideas on how to make an image move smooth and slow at the same time??

you could use millisecs() to move the image. just check millisecs time elapsed each movment update.

or, maybe use a float variable instead:

scroll# = scroll# + 0.5

How would I use the millisecs() idea??

I have already tried:
scroll# = scroll# + 0.5
it is still not smooth

something like this should do.

[CODE]

Graphics 640,480,16,2
SetBuffer BackBuffer()

Global next_check

While Not KeyDown(1)

;
If do_delay_check(2) = 1 Then
Print "Reset Timmer"
EndIf

Wend

Function do_delay_check(secs)
secs = secs * 1000
If Not MilliSecs() < next_check + secs
next_check=MilliSecs()
secs = 0
Return 1
Else
Return 0
EndIf
End Function

[/CODE]

kev

hmmm...I will try this

Luke - an image can only be placed to the nearest pixel, even if you use floats, hence the herkiness? If you have blitz3D you could try using a sprite with the image on and moving it with a float.

Would you happen to have an example of how to animate with a sprite...I thought sprites and images were the same

No, an image is just that, an image dtawn onto the screen pixel for pixel.

A sprite is a scalable, rotatable, etc. 3D object with an image on it.

ok I see...is there any examples in the blitz manuals on how to use sprites??
