Big problem with my first Unity project 😫

[ghaygeung0621]

Hi Hi, I’m a Unity beginner struggling with my first project! :((

I went to Unity Learn and am working on my first project, “Tanks: make a battle game for web and mobile”. I’ve added some tanks and made them move! However, when im tring to make the camera following the tank object. I cant find the target button on the control panal. pls help im struggling for about an hour

here is the script for camera control

using UnityEngine;

public class CameraControl : MonoBehaviour
{
    public float m_DampTime = 0.2f;
    public float m_ScreenEdgeBuffer = 4f;
    public float m_MinSize = 6.5f;
    [HideInInspector] public Transform[] m_Targets;

    private Camera m_Camera;
    private float m_ZoomSpeed;
    private Vector3 m_MoveVelocity;
    private Vector3 m_DesiredPosition;

    private void Awake()
    {
        m_Camera = GetComponentInChildren<Camera>();
    }

    private void FixedUpdate()
    {
        Move();
        Zoom();
    }

    // Public methods to manage targets
    public void AddTarget(Transform newTarget)
    {
        // Create new array with space for additional target
        Transform[] newTargets = new Transform[m_Targets != null ? m_Targets.Length + 1 : 1];

        // Copy existing targets if they exist
        if (m_Targets != null)
        {
            System.Array.Copy(m_Targets, newTargets, m_Targets.Length);
        }

        // Add new target at the end
        newTargets[newTargets.Length - 1] = newTarget;
        m_Targets = newTargets;
    }

    public void RemoveTarget(Transform targetToRemove)
    {
        if (m_Targets == null || m_Targets.Length == 0) return;

        // Find the index of the target to remove
        int index = System.Array.IndexOf(m_Targets, targetToRemove);
        if (index < 0) return;

        // Create new smaller array
        Transform[] newTargets = new Transform[m_Targets.Length - 1];

        // Copy all targets except the one to remove
        for (int i = 0, j = 0; i < m_Targets.Length; i++)
        {
            if (i != index)
            {

[HideInInspector] public Transform[] m_Targets;

Its been hidden from the inspector is why. Just remove the [HideInInspector] and it should draw again.

Not sure if the code comes like this, or if you added this yourself.

You should know that you can make screenshots more easily with the Windows Snipping Tool that you already have on your system.
