SendMessage doesn't seem to work

Questions & Answers

So i got the CircleCastAll to work, it debug.log’s nicely with what it collides with. I just have an error, i’ve added a sendmessage to the for loop, but when it collides with an object it says DamageTaken has no reciever. And i have a function called DamageTaken in another script, it’s public ofcourse. What i need the script to do, is to send the damage message to my other script, but why isnt it working?

My code is as follows:

Grenade.cs

    public Transform pointOfCircle;
	public float radius = 0.5f;
	public LayerMask whatIsDestroyable;
	public float distance = 1f;

	void Update()
	{
		RaycastHit2D[] hit;

		hit = Physics2D.CircleCastAll (pointOfCircle.position, radius, new Vector2 (1, 1), distance, whatIsDestroyable);

		for( int i = 0; i < hit.Length; i++)
		{
			Debug.Log("gameobject name " + gameObject.name + " hit");
			gameObject.SendMessage("DamageTaken", 1, SendMessageOptions.RequireReceiver);
			
		}

	}

and

TileHealth.cs

    public int health = 3;

	public void DamageTaken(int damage)
	{
		if(health > 0)
		{
			health -= damage;
		}

		if(health <= 0)
		{
			health = 0;
			Destroy (gameObject);
		}

	}

Help appreciated, thanks in advance

The problem, as indicated in the comments, is that the GameObject is sending a message to itself. hit is an array, so you need to access it by index.

The solution is as follows.

    for( int i = 0; i < hit.Length; i++)
    {
        Debug.Log("gameobject name " + hit*.transform.name + " hit");*

hit*.transform.SendMessage(“DamageTaken”, 1, SendMessageOptions.RequireReceiver);*
}
