Scrolling and Virtual width

Hello!
I'm making a platforming game with a single large level.
Using paralax scrolling I have a layer of fog in front of my level
and I have done this by using a screen sized image that is being wrapped around as I scroll the screen. (640*480)

The problem I'm facing is that with the use of a
frame size of 640*480 and a virtual width of 10000
I can't view/edit the entire level.

Even if I zoom out to 25% I am still only able to see 2/3 of the entire level.
The only way around this is to keep changing the "real" frame width to 10000 while editing and as soon as I need to run the game I need to change back to 640. (And also keep changing the virtual frame width again because it resets every time.)

Is there any other way around this?

Is there a reason that you're using the virtual width to extend the level sideways, rather than having the frame as 10000x480 and a window size of 640x480? (I haven't looked at the virtual dimensions myself.)

Yes the reason is that I use paralax scrolling and a single active object as an overlay fog on a seperate layer.
And the only way to get the layer content to wrap around the frame correctly is to use the same frame width as the content and a bigger virtual frame width for the level.

I just realised that I could perhaps use a quick backdrop object and let it extend over the entire level, but I will have to try that to see if it does not slow things down.

Even if that works I'm still wanting to get to the bottom of this problem.

You can increase the margins in the preferences of the frame editor.

Woah?! You can. Awesome never knew that. :D

Why not use the background system box. With it youR'e able to set your image transparent and you can "pattern" it.

Edit: Well, it would probably slow things down with a size you'd need.

Thanks Yves!
That's exactly what I needed,
and I don't understand why I didn't figure that out myself.
This will make my day so much easier!
