Objects entering a World?

Hey Everyone,

This is my first thread on the Forums here. I've been assigned a project for my Computer Science Class to create a short movie that consists of 4 scenes made in Alice. I'm doing it about a short game of Hide & Seek which should be relatively easy to program. Anyways, for most of my scenes I'd like to have it so people enter the world midway through. Kind of like a character would come on stage halfway through the scene in a play. Is there any way that I could accomplish this? Thanks!

Nevermind, this is a little embarrassing, but I never realized you could place objects outside of the screen to start. Problem solved!
