What type of glasses are required for this level? I’m using the Hardened Steel Glasses and character keeps returning “0” for total enemy health. Do I need to upgrade?

Never mind. I just asked a simple question hoping for a simple straight answer. I wasn’t sure if the glasses I was using could see through the wall or were line of sight only. I’ll just figure it out myself. Thanks anyway.

You don’t need to see through walls. The cannon can see ogres through walls. It’s written in the sample code.

This is what I was wondering. I knew about the cannon. Thank you.
