Unity中如何让攻击状态下的敌方AI停止移动与旋转？

Got it, let's sort this out for you. The core issue here is that your current code doesn't fully block rotation and movement logic when the enemy is in attack mode—even though you trigger the attack animation, state checks might still interfere if the player moves mid-attack. Here's a clean, reliable solution:

Step-by-Step Implementation #

1. Add an Attack State Flag #

First, add a private boolean variable to track if the enemy is actively attacking. This will let us skip all movement/rotation logic entirely when they're in the middle of an attack.

2. Block Logic During Attack #

At the start of your Update() method, check if the enemy is attacking. If yes, skip the rest of the frame's logic so the enemy stays locked in the attack state until it finishes.

3. Sync with Animation Events #

To make sure the flag updates perfectly when the attack starts and ends, we'll use animation events—this is more reliable than checking animation state every frame.

public class Chasev2 : MonoBehaviour 
{
    public Transform Player;
    public float Attack_range = 8.5f;
    public float Chase_range = 50.0f;
    public float rotation_speed = 10.0f;
    public float move_speed = 10.0f;
    
    private Animator anim;
    private float Distance;
    private bool isAttacking = false; // Track if enemy is in attack state

    void Start () 
    {
        anim = GetComponent<Animator>();
    }

    void Update () 
    {
        // Skip all movement/rotation logic if currently attacking
        if (isAttacking) return;

        // Default state setup
        anim.SetBool("Run", true);
        anim.SetBool("Idle", false);
        anim.SetBool("Attack", false);

        Distance = (Player.transform.position - transform.position).magnitude;

        // Chase state: move and rotate towards player
        if (Distance <= Chase_range && Distance > Attack_range) 
        {
            Vector3 Direction = Player.position - transform.position;
            Direction.y = 0; // Keep rotation on Y-axis only
            transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation(Direction), rotation_speed * Time.deltaTime);
            transform.eulerAngles = new Vector3(0, transform.eulerAngles.y, 0);
            transform.position += transform.forward * move_speed * Time.deltaTime;
        }
        // Idle state: no movement
        else 
        {
            anim.SetBool("Run", false);
            anim.SetBool("Idle", true);
            anim.SetBool("Attack", false);
        }

        // Trigger attack when player is in range
        if (Distance < Attack_range) 
        {
            anim.SetBool("Run", false);
            anim.SetBool("Attack", true);
            anim.SetBool("Idle", false);
        }
    }

    // Called via animation event when attack starts
    public void StartAttack()
    {
        isAttacking = true;
    }

    // Called via animation event when attack ends
    public void EndAttack()
    {
        isAttacking = false;
    }

    void OnDrawGizmosSelected() 
    {
        Gizmos.color = Color.red;
        Gizmos.DrawWireSphere(transform.position, Attack_range);
        Gizmos.color = Color.yellow;
        Gizmos.DrawWireSphere(transform.position, Chase_range);
    }
}

How to Set Up Animation Events #

1. Open your enemy's attack animation clip in the Animation window.
2. Move the playhead to the start frame of the attack, right-click the timeline, and select Add Event.
3. In the event inspector, select your Chasev2 component, then choose the StartAttack() method.
4. Move the playhead to the last frame of the attack (or just before it loops), add another event, and select the EndAttack() method.

Why This Works #

• The isAttacking flag ensures that once the enemy starts attacking, all movement and rotation logic is paused until the attack finishes.
• Animation events sync the flag perfectly with the attack animation, so you won't get weird state glitches if the player moves during the attack.
