Platform isnt going back

I have made a moving platform in my platformer game. It consists of parent object “Platform” on layer “Platform” with two boxcolliders (trigger and not), rigidbody and the script, two child objects with visual and another child object on layer “Ground” with boxcollider.
When it hits an object on layer “Ground” it continues to move until it goes near the startPos position and only then types “OK” in the consol. I checked everything and nothing seems wrong

Code of the platform:

    [SerializeField] private Vector3 startPos, endPos;
    [SerializeField] private LayerMask groundLayer, playerLayer;
    [SerializeField] private float speed;
    [SerializeField] private float platformSize;
    [SerializeField] private bool isMovingHorizontaly;

    private Vector3 targetPos;
    private Player playerComponent;
    private UI uiComponent;

    private void Awake()
    {
        playerComponent = FindObjectOfType<Player>();
        uiComponent = FindObjectOfType<UI>();
    }

    private void Start()
    {
        if (isMovingHorizontaly)
        {
            startPos.y = transform.position.y;
            endPos.y = transform.position.y;
        }
        else
        {
            startPos.x = transform.position.x;
            endPos.x = transform.position.x;
        }

        platformSize -= 0.1f;
        targetPos = endPos;
    }

    private void Update()
    {
        PlatformMovement();
    }

    private void PlatformMovement()
    {
        if (Vector3.Distance(startPos, transform.position) < 0.05f)
        {
            targetPos = endPos;
        }
        else if (Vector3.Distance(transform.position, endPos) < 0.05f)
        {
            targetPos = startPos;
        }

        if (CheckPlatformObstacle(groundLayer))
        {
            targetPos = startPos;
            Debug.Log("OK");
        }
        else if (CheckPlatformObstacle(playerLayer) && playerComponent.CheckGround())
        {
            targetPos = startPos;
            uiComponent.ChangeUIValue(-1, true);
            Debug.Log("OK");
        }


        transform.position = Vector3.MoveTowards(transform.position, targetPos, speed * Time.deltaTime);
    }


    private bool CheckPlatformObstacle(LayerMask checkLayer)
    {
        float boxAngle = 0f;
        float boxDist = 0.05f;
        Vector2 boxOrigin = transform.position;
        Vector2 boxSize = new Vector2(platformSize, boxDist);
        Vector2 boxDir = Vector2.down;

        bool platformReturn = Physics2D.BoxCast(boxOrigin, boxSize, boxAngle, 
                                                boxDir, boxDist, checkLayer) && targetPos != startPos;

        return platformReturn;
    }

Apparently, I switched positions of startPos and endPos
Im actually that stupid :sweat_smile:

No, that’s just how software and gamedev works… really.

And I’m not just saying that to make you feel good.

Wait until you do it on a tech demo to a room full of all your coworkers.

And they stare at you making the error for five minutes and none of them recognize it either.

That’s why we have debugging!!

By debugging you can find out exactly what your program is doing so you can fix it.

https://docs.unity3d.com/Manual/ManagedCodeDebugging.html

Use the above techniques to get the information you need in order to reason about what the problem is.

You can also use Debug.Log(...); statements to find out if any of your code is even running. Don’t assume it is.

Once you understand what the problem is, you may begin to reason about a solution to the problem.

If you get a chance, come back and flair your post as RESOLVED please!
