How do I move an object towards a moving object within a coroutine?

Hello,

I've been trying to figure out in a coroutine how to move a gameobject towards another gameobject that is moving, but I haven't had any luck. I can get my player to move towards a static location(where the "enemy" was) but I can't figure out how to get the current position after it moves.

How would I go about doing this?

Thanks!

Code (CSharp):

1.  
2.         public void SetDestination(Vector3 worldPos)
3.         {
4.             navMeshAgent.destination = worldPos;
5.         }
6.  

Code (CSharp):

1.         private bool IsTargetInRange(GameObject target)
2.         {
3.             var distanceToTarget = (target.transform.position - transform.position).magnitude;
4.             return distanceToTarget <= weaponSystem.GetCurrentWeapon().GetMaxAttackRange();
5.         }

Code (CSharp):

1.         IEnumerator MoveToTarget(GameObject target)
2.         {
3.             print("calling MoveToTarget");
4.          
5.             while (!IsTargetInRange(target))
6.             {
7.                 character.SetDestination(target.transform.position);
8.  
9.                 yield return new WaitForEndOfFrame();
10.             }
11.             yield return new WaitForEndOfFrame();
12.         }

 

Assuming you have a reference to the enemy you're chasing

Code (csharp):

1.  
2. var position = enemy.transform.position;
3. player.transform.position = Vector3.MoveTowards(player.transform.position, enemy.transform.position, PlayerSpeed * Time.deltaTime);
4.  

 

Thanks for the reply, doesn't this need to be called within the update loop?

 

You can do it in a coroutine, it just needs a loop of some kind.

Code (csharp):

1.  
2. IEnumerator followPlayer()
3. {
4.        while(true){
5.         float playerDistance = Vector3.Distance(transfrom.position , player.position);
6.         if(playerDistance > 5.0f)
7.         {
8.             //move toward player
9.  
10.         }
11.         yield return null;
12.        }
13. }
14.  

That's just a quick example, I'm sure there are better ways to do it.

 

hmm, I am looping my current code, but I am using navmeshagent.destination(target.position). How is this different?
I've updated my original post with my code.

 

It's not any different. Doesn't it work?

 

If I run it like it is now(code posted in OP) the player will run toward the last position of the enemy(when it was clicked) The position isn't being updated.

 

It's probably a good idea to double check that the destination you're setting is actually valid. That method gives you back a boolean indicating whether or not it was

You might be safer getting an actual position on the NavMesh that's close to the enemy instead of just using the enemy position directly
