Scratch

Just make it one variable, velocity. You're probably looking for:

when  clicked
forever
change 
scroll x ▼
 by 
sin ▼
 of 
direction
 * 
velocity
change 
scroll y ▼
 by 
cos ▼
 of 
direction
 * 
velocity
if 
key 
up arrow ▼
 pressed?
change 
velocity ▼
 by 
1
set 
velocity ▼
 to 
velocity
 * 
0.87

Do you understand trig? If you don't ill be glad to summarize what this script does and why it works.

Thanks! Can you?

So in very rough, basic terms...

Imagine a circle with a radius. No matter what direction the radius is pointed in, it always is the same length, right? Basically, sin(Direction) and cos(Direction) describe a radius of that circle. They give you the slope of that radius.

So in the script, your "radius" length is equal to the velocity variable, and the sin and cos give you the slope of that radius. Because you have the slope, you can scroll in any direction, and the velocity thing makes it smooth.

is it possable to make x volocity in a scrolling game?

I think this will work; I'll go check and edit if I need to.

Works!
