version: "1.0.1" description: Creating enemies, NPCs, and AI-controlled characters

Adding Enemies and NPCs

Use this skill when the user wants enemies, hostile creatures, NPCs, or AI-controlled characters.

Trigger Phrases

• "enemy", "enemies", "bad guy", "monster"
• "NPC", "character that moves on its own"
• "AI", "chase", "patrol", "attack"
• "zombie", "robot", "guard", etc.

Implementation Checklist

1. Create Enemy GameObject

• Visual representation (often red-tinted for enemies)
• Appropriate collider (trigger for damage zones)
• Tag as "Enemy" for identification

1. Add AI Behavior

• Choose pattern based on description:
• Chase: Move toward player
• Patrol: Move between waypoints
• Stationary: Turret-style, doesn't move
• Wander: Random movement

1. Add Combat (if applicable)

• Health system
• Damage dealing (trigger collider)
• Death behavior (destroy, ragdoll, respawn)

1. Multiplayer Setup (Normcore)

• Add RealtimeView
• Add RealtimeTransform
• Consider ownership: server-authoritative or first-hit-owns

1. Spawning

• Create prefab in Resources/
• Set up spawner if needed (waves, continuous)

AI Patterns

Simple Chase

void Update()
{
    if (target == null) target = GameObject.FindWithTag("Player")?.transform;
    if (target != null)
    {
        Vector3 dir = (target.position - transform.position).normalized;
        transform.position += dir * speed * Time.deltaTime;
        transform.LookAt(target);
    }
}

Patrol Between Points

public Transform[] waypoints;
private int currentWaypoint = 0;
 
void Update()
{
    Transform wp = waypoints[currentWaypoint];
    transform.position = Vector3.MoveTowards(transform.position, wp.position, speed * Time.deltaTime);
 
    if (Vector3.Distance(transform.position, wp.position) < 0.5f)
        currentWaypoint = (currentWaypoint + 1) % waypoints.Length;
}

Chase + Patrol Hybrid

void Update()
{
    float distToPlayer = Vector3.Distance(transform.position, player.position);
 
    if (distToPlayer < detectionRange)
        ChasePlayer();
    else
        Patrol();
}

Health & Damage

public class EnemyHealth : MonoBehaviour
{
    public int maxHealth = 3;
    private int health;
 
    void Start() => health = maxHealth;
 
    public void TakeDamage(int amount)
    {
        health -= amount;
        if (health <= 0) Die();
    }
 
    void Die()
    {
        // Spawn particles, play sound
        Destroy(gameObject);
    }
}

Output to User

Explain behavior simply:

• "I added enemies that will chase you when you get close"
• "They have 3 health - shoot them 3 times to defeat them"
• "New enemies spawn every 5 seconds from the edges"
