Hi all

This is the second time I've typed this one - if you find the other version (coz I can't), please delete it.

Im using a scroll to pan across a background 2048 x 768. What I want to do is hold some foreground object static while the background pans behind it. Is there a standard way of doing that?

If not, do I have to move a node in the opposite direction to the scroll - and if so, how do I ensure the speed is exactly synchronised so the foreground does not appear to move?

Anybody got any ideas for me?

Thanks

Any layer with the same dimensions as the game viewport will not scroll. Does that solve your problem?

It did indeed Mnem, thanks. Perfect.

Now what I'd like to do is to alpha the objects in and out while the scroll is happening. The Scene.ScrollTo is an absolute is it not? Once started, it carries on and the next line of code executes when the scroll finishes, it would appear.

Is there any way within Wintermute to run a for(a = etc) thingy.AlphaColor = MakeRGBA(255,255,255,a) (youknowhatImean) while the scroll is happening?

Cheers

There's Scene.ScrollToAsync(), which doesn't block the script flow.
And generally speaking, you can fake multiple "threads" by using events:

Code: WME Script

1. ...
2. this.ApplyEvent("fade_code");
3. Scene.ScrollTo(something);
4. ...
5.  
6.  
7. on "fade_code"
8. {
9.   // code put here will run in parallel with the scolling
10. }
11.

Works perfectly, and I can see other uses for what you've taught me this evening. Perhaps the game should say "the titles of Chapter One are brought to you by Mnemonic's code examples", for 'tis the truth indeed.

Cheers
