Hi guys, and yes I've read the ultimate background system object tutorial before (very helpful!)

The thing is, I've not used MMF2's layers at all yet and I've heard that this is the best way to make some cool parallax scrolling effects. Any idea on where I'd learn more about doing it this way? Or if it's the best way in MMF2?

Thanks!

In MMF2, play around with the layers X and Y coefficients in the Layer properties. Very easy way of doing parallaxing

Edit: And use the layers! I don't think I could make a game without them now

I found thats it's actually easier to use active picture object for parallax in Lil' pirate. Although the only reason i chose that was to load objects from a file.
I don't think using MMF2 layers specifically for parallax is the best idea. Active picture objects are more versatile and easier to organise.

Ditto. I've never bothered with parallaxing before but now i'd never go back! Layers is the way forward, i think!

Can you change a layer's coefficient during runtime, so it can, say scroll from left to right, to stop?

 
It'll all blow over.

The Layer Object extension gives you additional functions, like changing the coefficients at runtime.

The only downside is that using many layers causes slowdown. But everybody will use HWA soon anyway so everything will be faaaaast.

Active picture objects are faster than layers.

Layers are a hell of a lot more flexible then the extremely slight performance drop might make them seem worth. Animations, multiple objects on multiple layers. It's all just a lot cleaner to work with, and make the process of designing the game, far more efficient.

ArcaneTale uses over 10 layers and I haven't noticed even so much as 1fps lost.

It seems to really depend on...something. I have projects using many layers without slowdown, others (Fishhead 4) are running crap since I added layers.

It's probably the size. I'd Imagine the impact of layers is multiplied a lot when going from 320/240 to 640/480 or greater.

My "game" had a frame size of 19,000 wide, 5 layers and photoshop gfx and there wasn't much slowdown for me.
