Enemy progress

I've been working on two types of enemies. One that rams you, one that stands at a distance and shoots at you.

David, I can't figure out how to get "forces" to work right on the ramming enemy, so I've just plugged in the velocity transform. Feel free to attempt your own solution.

Here is the link to my CS file for the ramming enemy.

This enemy will die and toss out two junk objects. Take a look at how I did it.

Things I'm working on:

• Getting the shooting enemy to shoot.
• Creating a spawning controller, I have one that works now, but it lags alot.
