Hello.
i am a newbie and have a simple question.
I have a hurt animation on the enemy that is triggered when the player shoots it. Suppose the enemy is chasing the player and the player shoots it while chasing him, the hurt animation is triggered. However, i would like to freeze the enemy movement(freeze the chase) when the hurt animation is triggered. This might be a simple fix, but i cant seem to get it done.
Here is the code that is responsible for the enemy movement
public class NewEnemyScript : MonoBehaviour
{
//use holster master as the player target
[SerializeField] private Transform playerTarget;
[SerializeField] private float attackRange;
[SerializeField] private float alertRange;
[SerializeField] private float moveSpeed;
[SerializeField] private Animator anim;
void Update()
{
if(Vector3.Distance(playerTarget.position,this.transform.position)<alertRange)
{
Vector3 direction = playerTarget.position - this.transform.position;
direction.y = 0;
this.transform.rotation = Quaternion.Slerp(this.transform.rotation, Quaternion.LookRotation(direction), 0.1f);
anim.SetBool("isIdle", false);
if(direction.magnitude>attackRange)
{
this.transform.Translate(0, 0, moveSpeed);
anim.SetBool("isRunning", true);
anim.SetBool("isAttack", false);
}
else
{
anim.SetBool("isAttack", true);
anim.SetBool("isRunning", false);
}
}
else
{
anim.SetBool("isIdle", true);
anim.SetBool("isAttack", false);
anim.SetBool("isRunning", false);
}
}
i have an other script named health that is attached to the enemy and the hurt animation is triggered here when the bullet is collided with the enemy along with a deduction in health
public class NewHealth : MonoBehaviour
{
[SerializeField] private float enemyHealth = 100f;
[SerializeField] private Animator animator;
private bool isDead = false;
[SerializeField] private float deductHealth = 10f;
void Update()
{
if (!isDead)
{
if (enemyHealth <= 0)
{
enemyDead();
}
}
}
public void DeductHealth()
{
if (!isDead)
{
enemyHealth -= deductHealth;
animator.SetTrigger("Hurt");
}
}
void enemyDead()
{
Destroy(gameObject, 5);
animator.SetBool("isDead", true);
isDead = true;
}
private void OnTriggerEnter(Collider other)
{
if(other.gameObject.tag=="Bullet")
{
DeductHealth();
Destroy(other.gameObject);
Debug.Log("Hurt");
}
}
Here is the animator window
any help would be greatly appreciated. Thank you for your time.
It looks like youre using root motion
and mecanim to drive the zombies
movement? Depending on what your hurt
animation is actually animating is
determining the zombies movement
speed. if you want the zombie to
pause longer in the hurt state your
animation should actually include
that pause.
if youre trying to get the zombie to
pause after every hurt but dont have
the means to modify/add a new hurt
animation you could insert a new
animation to follow up the hurt
animation and then transition from
that new animation to the other
states. you could try putting another
“Zombie Idle” animation into your
mecanim state machine and name it
something like “pause”. have “Hurt1”
transition only to that state then
reconnect the new “pause” state to
zombie idle. The transition from
pause → idle should have “Has Exit
Time” checked and you would set the
“Exit Time” setting to however long
you want that pause to play.

If this is not what you meant and I
misunderstood then maybe youre
looking to stop the zombie from
rotating? In order to do this you
need to know when the zombie is
actually hurt. I added some things to
your code and commented my additions,
maybe it will help.
