How do I stop 2 objects with dif velocities from overlapping

Using the auto runner template

How do I get objects moving at the same angle to increase their speed without overlapping each other? Like in the infinite runner “canabalt” The distance between buildings vary but stay constant with increasing speed.

Or at least it appears to be constant.

parallax

Thanks! but I don't think that what I need for this but I could be wrong. Parallax is definitely something I want though, I'm going to have to rethink how I design my images with this.

I found a capx of what I was looking for on this site. I've been learning about floors, and ceils and modulo to make this work, so far so good.

Parallax controls the scale rates for layers. You have a lower number for a slower rate of movement. So the farther "away" a background layer is the lower the parallax value needs to be.
