My enemy seems to chase the player when out of range or at least that is what looks to be happening
on closer inspection, it seems to be more confusing.
with a wire gismo in use and a chase range of 8. The wire gismo does not connect with the player, however the enemy will still give chase, the inspector shows a distance of 7.7… so I’m a bit confused as to what has happened
is the distance incorrect or the gismo, or is there something else that I have missed
This also affects the distance of attacks, as enemy’s are able to attack from what appears to be 5 units of distance while the inspector shows less than 1 unit of distance.
just so anyone who sees this knows, the player in the screen shot is in the bottom right of the map
I have moved the enemy even further away from the player and distance seems to have decreased. and it seems the enemy (the one that is selected) is the only one to be provoked from frame one
You’re not showing any code, so it’s quite difficult to see where the problem lies
Hi, sorry ill paste the code now but from what I can tell, its the code shown in the videos with some added comments for my own use
Enemy AI script
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;
public class EnemyAI : MonoBehaviour
{
[SerializeField] Transform Target;//player
[SerializeField] float turnspeed = 5;
[SerializeField] float chaserange = 8f;
[SerializeField]bool isprovoked = false;
NavMeshAgent navMeshAgent;
[SerializeField] float distancetotarget = Mathf.Infinity;//set to infinate to avoid enemy chase at start
// Start is called before the first frame update
void Start()
{
Target = FindObjectOfType<PlayerHealth>().GetComponent<Transform>();//find player objet based on playerhealth - no need to drag in inspector
navMeshAgent = GetComponent<NavMeshAgent>();//get nav mesh for use
}
// Update is called once per frame
void Update()
{
distancetotarget = Vector2.Distance(Target.position, transform.position);
if(isprovoked)//check bool
{
EngageTarget();
}
else if (distancetotarget <= chaserange)//if player is close-set bool
{
isprovoked = true;
}
}
public void onDamageTaken()//call via broadcast
{
isprovoked = true;
}
void EngageTarget()
{
faceTarget();
if (distancetotarget >= navMeshAgent.stoppingDistance)
{
ChaseTarget();//follow target - close distance
}
if(distancetotarget < navMeshAgent.stoppingDistance)
{
attackTarget();
}
}
void ChaseTarget()
{
GetComponent<Animator>().SetBool("Attack", false);//set bool for animator
GetComponent<Animator>().SetTrigger("Move");//set trigger animation
navMeshAgent.SetDestination(Target.position);//follow target
}
void attackTarget()
{
GetComponent<Animator>().SetBool("Attack", true);//set bool for animator
Debug.Log("witty " + name + " " + distancetotarget);//attack target
}
private void OnDrawGizmosSelected()
{
Gizmos.color = new Color(1, 1, 0, 0.75f);//show range of chase
//Gizmos.DrawSphere(transform.position, chaserange);//useful in scene view for seeing object view
Gizmos.DrawWireSphere(transform.position, chaserange);
}
void faceTarget()
{
Vector3 direction = (Target.position - transform.position).normalized; //get vector between enemy and target
Quaternion lookRotation = Quaternion.LookRotation(new Vector3(direction.x, 0, direction.z));//set new look to be target
transform.rotation = Quaternion.Slerp(transform.rotation, lookRotation, Time.deltaTime * turnspeed); //rotate to face target with a speed
}
}
enemy attack script
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class EnemyAttack : MonoBehaviour
{
PlayerHealth target;
[SerializeField] float damage = 40f;
// Start is called before the first frame update
void Start()
{
target = FindObjectOfType<PlayerHealth>();//find player for this script in scene
}
public void AttackHitEvent()//use event flags in animaton window
{
if(target == null)
{ return; }
target.takeDamage(damage);//call function on player refrnced in inspector
}
}
enemy health script
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class EnemyHealth : MonoBehaviour
{
[SerializeField] float hitpoints = 100;
public void takeDamage(float damage)
{
//GetComponent<EnemyAI>().onDamageTaken();//possable way - keep here
BroadcastMessage("onDamageTaken");//calls on gameobject or children - calls all named functions
hitpoints -= damage;// = hitpoints - damage;
if(hitpoints <= 0 )
{
Destroy(gameObject);
}
}
}
I’m not sure if there is anything else that would affect this issue, i don’t want to full the feed with code that wont be useful so please let me know if I should show anything else
I think this is the problem. You are working with a 3D game here, but you are calculating the distance using a 2D vector. It’s completely ignoring the z-axis. You should be using Vector3.Distance(...).
Thank you, I must have miss typed it and didn’t notice any difference when doing the earlier tutorials. fresh pair of eyes always seems to help
