Waterfall SFX and rivers

[Chaos]

How do I make waterfall SFX near waterfalls and make rivers flow??

 

[I'll Begin]

Look through the things list in SRB2 Doombuilder or otherwise on the Wiki. I'm sure it'll be pretty clear after that. :P

It's a Thing, look at sounds or scenery.

I got a river to work bu I have a problem: How would I make the textures scroll and make it go in a specific direction? Player 1 starts facing north, the direction I want, but it goes south.
