In this chapter, we will learn some algorithm recipes for simulating senses and agent awareness:

• The seeing function using a collider-based system
• The hearing function using a collider-based system
• The smelling function using a collider-based system
• The seeing function using a graph-based system
• The hearing function using a graph-based system
• The smelling function using a graph-based system
• Creating awareness in a stealth game
