As seen in the previous screenshot, the states and their transitions are as follows:
• Idle | Attack and PlayerSeen is true means attack the player when the Goblin
sees him.
• Idle | Defend , PlayerSeen is true , and PlayerAttacking is true means if the
player attacks first when they are seen by the Goblin, then defend.
• Attack | Defend and PlayerAttacking is true means switch to defend if the
player attacks.
• Defend | Attack and PlayerAttacking is false means as soon as the player
stops attacking, switch back to Attack .
• Any State | Idle and PlayerSeen is false means if the Goblin loses sight of the
player at any time, go back to Idle .
• Any State | Run Away , EnemyHealth is less than 2 , and PlayerHealth is great-
er than 2 means the Goblin is basically a coward. If at any time their health drops
too low and the player is a lot healthier, it will run away as fast as its little legs
