Reality Factory

I am composing a game where the changeLevel entity is placed in a "sewer pipe". As the player runs through the sewer towards the open end, he will pass the changeLevel entity. I would like to have the level change triggered when the player is within a certain distance of it. The distance itself isn't too critical, I just don't want the player to really move beyond the changeLevel entity.

I read the manual that came in the docs folder as well as querying a few relevant terms on here in hopes of resolving this on my own. I have also googled a few external tutorials as well.

Thanks in advance to those that help me out with this.

Meh, I got it. I created a transparent brush and tied it to a model. The model thing is new for me so far.
