Unity Engine "SendMessage has no receiver" Error

SendMessage ReceiveDamage has no receiver!
UnityEngine.Component:SendMessage (string,object)
Weapon:OnCollide (UnityEngine.Collider2D) (at Assets/Scripts/Weapon.cs:56)
Collidable:Update () (at Assets/Scripts/Collidable.cs:27)
Weapon:Update () (at Assets/Scripts/Weapon.cs:28)

Error Image Weapon Code Part 1 Weapon Code Part 2 Collide Code

I have tried using base.Update(); and just copying and pasting the code but the error still shows up.

I'm very new to game development and can't figure this out.

I figured it out.... I had put the enemy script on both the enemy and the enemies hitbox, removing it from the hitbox fixed the issue.

This error means that no object is receiving the message you sent, because you are sending it through "coll", which is a Collider2D. You have to send it through the GameObject like this:

coll.gameObject.SendMessage("ReceiveDamage", dmg);

For this to work, the collided GameObject (which in this case is a "Fighter") must have a script attached to it that also has a function called ReceiveDamage.

You can learn more about this here: https://docs.unity3d.com/ScriptReference/GameObject.SendMessage.html
