So i made a little game where i want to make a cube jump from a point to another by clicking on point's colliders with a specific tag named "RichPoint"... I have this code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour {
    public float jumpMaxDistance;
    public float jumpSpeed;
    private float distance;
    private bool firstFrame = false;
    private Vector3 richPoint;
    public GameObject player;
    private Animation jump;
    private float pBTime;
    void Start () {
        richPoint = transform.position;
        jump = player.GetComponent<Animation> ();
    }
    // Update is called once per frame
    void Update (){
        //Moves the player to the next richPoint.
        if (firstFrame == true){
            if (transform.position != richPoint) {
                transform.position = Vector3.MoveTowards (transform.position, richPoint, Time.deltaTime * jumpSpeed);
            }//executes if the left click is pressed.
        }
        if (Input.GetMouseButtonDown (0)) {
            RaycastHit hit;
            //Get Ray from mouse position.
            Ray rayCast = Camera.main.ScreenPointToRay (Input.mousePosition);
            //Raycast and check if any object is hit.
            if (Physics.Raycast (rayCast, out hit, jumpMaxDistance)) 
                {
                //Raycast and check if any object is hit.
                if (hit.collider.CompareTag ("RichPoint"))
                {
                    richPoint = hit.collider.transform.position;
                    //This finds the distance between the player and richPoint.
                    distance = Vector3.Distance(transform.position,richPoint);
                    pBTime = distance / pBTime;
                    //This plays the Animation depending on tha distance between transform.position and richPoint.
                    jump ["PlayerJump"].time = pBTime;
                    jump.Play ();
                    firstFrame = true;
                }
            }
        }
    }
}
Now...if i run the game and try to click on colliders i get this errors...
