Ambiguous reference between two references

Hello! I am getting an error when initializing the Vector 3 targetPosition in the code below.
This is the error code:
Here is the error:
Error CS0104 ‘Vector3’ is an ambiguous reference between ‘System.Numerics.Vector3’ and ‘UnityEngine.Vector3’

Here is my code:

using System.Collections;
using System.Collections.Generic;
using System.Numerics;
using UnityEngine;

public class Enemy : MonoBehaviour
{
[SerializeField]
private Transform[] waypoints;
private Vector3 targetPosition;
// Use this for initialization
void Start()
{
targetPosition = waypoints[0].position;
}
// Update is called once per frame
void Update()
{

}
}

 

Class definitions can have the same name while being in different namespaces. There is a definition for

Vector3

in

System.Numerics

and there is one in

UnityEngine

. Since you use both of these namespaces in this code via using directives, it gets confused what it should use.

Either remove

using System.Numerics;

, which doesn't appear to be used in the code, or add the following line under your using directives:

Code (CSharp):

1. using Vector3 = UnityEngine.Vector3;

 

Thank you so much! That solved my problem! You are a savior and a scholar!

 

thanks alot. i was using both
using system.Numeric;
using UnityEngine;

now i am only
using UnityEngine;

 

Thank you so much dude i just started learning unity and this happened to me!
