State Machine AI for 3D Enemies

Build the enemy's state machine with an Idle state as the foundation of its AI.

A view cone spots threats, and line-of-sight raycasts confirm walls block the player.

The enemy navigates around walls to reach you, then gives up when it loses sight.

It attacks and damages you, flinches when hit, and dies when health runs out. Your first playable enemy.

When idle, the enemy patrols random points on the navmesh until it spots you.

After attacking, the enemy backs off to open distance and avoid getting cornered.

The enemy circles and strafes around you at range, sizing you up before closing in.

A ranged-class flag turns the melee charger into an archer that holds a safe distance.

Build a projectile and ranged attack state so the kiter looses bolts that fly and hit.

Wire enemy_damaged and enemy_killed events so quests, HUD, and score plug into the fight.

The enemy grows a HurtBox for your weapon to land on, creating a real two-sided fight.

Different hit weights trigger different reactions: jabs barely rock it, heavy blows send it reeling.

A telegraphed dash closes the gap fast and flows into a strike, gated by a cooldown so it can't spam.

Wire every state together, verify nodes match class names, and walk the full behavior loop end to end.
