How do I make objects scroll in

How do I make objects (not enemy ships) scroll in, as they do in Super R Type video game etc. I've searched the internet and will put in some serious searching on the forums too but if anyone can give me a starting point. I know about spawn points and i'm sure it's to do with instance or global variables.

Thanks

Although the question isn't very clear..

I guess a very simple solution would be creating an object outside of the viewport and using the bullet behaviour to move it to the desired spot..

Hi,

Thanks for your reply.

I mean objects as in obstacles, maybe a large rock or other item. Working on a side scrolling game and want my obstacles to scroll in and scare the player.

Ok, so why won't the above explanation work for that?

I will try it.
