Create your own NPC Medic

Medics are a common character archetype in many games. A medic's job is to heal nearby characters, and they help their teammates recover after sustaining damage. Medics serve different roles depending on the game, for instance, doctors that serve patients in a hospital, combat medics that help their team fight as well as heal, or neutral stations that heal anyone.

The medic character you'll create in this example follows a set of logic rules.

• Idle:
• Begin Healing Agents
• Healing Loop
• Navigate to Agent

The medic begins idle, and patrols until an agent enters the healing zone. That agent gets added to the medic's healing queue. The medic needs to track the agent it needs to heal next, and a queue provides a useful data structure for this purpose since queues are a first-in, first-out data structure. This means the character that enters the healing zone first will be the first to get healed.
