Did you see http:#30504337 ???
Actually, maybe not -- I've just looked through the code again and I see this is probably correct.

I dont think so, I am trying to create two scrollers that are nearly identical to one another one for obstacles in my game and the other for powerups. If you check out line 76 this is the sprite on my other scroller.

What line in the example code corresponds to line 155 that the error occurs?
ASKER
This line is the one that gets flagged up
powerupScroller sc(2000,width,sSprite,400)
powerupScroller sc(2000,width,sSprite,400)
Hmmm. Think we might need to have a go at building this. Can you post all the code required to build this?
ASKER
I have zipped all my code up and posted this hope you can use this to see the error

Ok, thanks :)
At work right now but I'll look at this when I get home (assuming no one else has done so in the mean time).
