How to make an enemy spawn facing a certain way

[Your Computer]

That sounds like exactly what I am aiming for! Though my final question is, how do I increase the activation distance of the enemy?

Open up the monster of choice in the model editor. Then go to Settings > User defined variables. You'll find it there; you can't miss it. When saving, though, be sure to give the .ent file a different name (e.g. servant_grunt_longrange.ent), or else the game will choose the original. Then in the level editor, click on the monster and on the right click on "..." and open your modified monster. Also, i hope you followed step 8 on setting up a development environment.
