error 1061 how to fix it?

Getting Started
1

can anyone tell me what is wrong with this method

public class BallScript : MonoBehaviour
{
    Vector3 targetPos = new Vector3(0f, 0f, 0.7f);

    public void FallInHole()
    {
        transform.position += new Vector3(0f, 0f, 0.7f);
        transform.position = Vector3.Lerp(transform.position, targetPos, (Time.deltaTime * 3) / Vector3.Distance(targetPos.transform.position));

my attempt is to get the object to move in two directions at different times upon entering a trigger. This method is called from another script. error cs 1061 on line 8, 124 vector 3 does not contain a definition for transform.

targetPos is a Vector3, not a GameObject, so this doesn’t work:

targetPos.transform.position

Just remove the transform.position part.

finally fixed it so no errors occur. here is my new script

using System.Collections;
using System.Collections.Generic;
using System.Collections.Specialized;
using System.Runtime.InteropServices;
using System.Security.Cryptography;
using System.Threading;
using UnityEngine;

public class BallScript : MonoBehaviour
{
    Vector3 targetPos = new Vector3(13f, 0f, 0.7f);

    public void FallInHole()
    {
        transform.position += new Vector3(0f, 0f, 0.7f);
        transform.position = Vector3.Lerp(transform.position, targetPos, (Time.deltaTime));

My intent is to get the ball to go to the bottom of the pocket then roll to the center of the table(which is at 13,0,0.7) when I had it as 0,0,0.7 I noticed some skipped movement but when I change it to this ball does not go to the new vector coordinates. no problem though getting it to sink to the bottom of the pocket.

I wonder though, am I telling the ball to move a targeted position of 13,0,0.7 or am I telling it to move 13 units on the x axis?

Also, what is up with the stuff at the top? I didn’t write that in.

Vector3.Lerp (and all other lerp functions) isn’t supposed to be used with Time.deltaTime, as it doesn’t move a Vector3 over time.

The t parameter in all lerp functions is supposed to be a number between 0 and 1, where:

  • 0 = exactly the first value (the first Vector3 parameter).
  • 1 = exactly the second value (the second Vector3 parameter).
  • 0.5 = exactly halfway between the two values.

You probably want to use Vector3.MoveTowards instead.
You can also remove this line…

transform.position += new Vector3(0f, 0f, 0.7f);

…As this is just setting the position of the object to a fixed position (presumably every frame).

Visual Studio will auto-import namespaces if you insert a type name under a namespace in your code. You probably did so at some point.
You can safely remove all the namespaces that are grey-d out, which means they’re not being used.

Thanks for the reply your advice worked but it didn’t move exactly the way I wanted. I did, however, come up with an idea based on your response. I’m going to have a 2nd trigger located below the first trigger. trigger1 sends the ball to trigger 2 and trigger 2 sends the ball towards the center of the table. a little complicated I know and probably unnecessary but I have to go with what I know which isn’t much yet. After reading and learning I came up with this for trigger 2:

public class Trigger2: MonoBehaviour
{
    Vector3 targetPos = new Vector3(0f, 0f, 0.7f);
    public float speed = 5f;
    public maxDistanceDelta (13f, 0f, 0.7f);

    void OnTriggerEnter(Collider ballCollider)
    {
        if (ballCollider.gameObject.CompareTag("Ball"))
        {
            transform.position = Vector3.MoveTowards (targetPos,(speed * maxDistanceeDelta * Time.deltaTime) / Vector3.Distance(targetPos.transform.position);


        }
    }
}

Getting error 1001 identifier expected for line 5. I have read up on identifiers but maybe you can dumb it down for me.
My take is it just means I have to name maxDistanceDelta something to be referred to later.

You didn’t give maxDistanceDelta a type. Did you mean to make it a Vector3?

public Vector3 maxDistanceDelta = new Vector3(13f, 0f, 0.7f);
