Prefab instantiated as an object with my methods-CodePudding

I have an idea that there must be a way to attach a class to a prefab - basically to add my own methods to the code. Then, when I instantiate my prefab in runtime I want it to be an instance of this class.

Now, I can attach a script to a prefab and it's Start and Update works, but my idea is something like this:

public class PowerupWidget : MonoBehaviour {
    void Start() {
        Debug.Log("PowerupWidget created!!!");
    }
    void SetTitle(string title) {
        // ... set the prefab's title widget text ...
    }
}

When I instantiate my prefab, the Start method is called. But the instance is of course the GameObject type.

// in my scene script:
// prefab is my PowerupWidget
GameObject p = Instantiate(prefab, transform.position, Quaternion.identity, this.transform);
// here p is GameObject of course

Is there a way how to get to the instance of the PowerupWidget class, or am I completely wrong in my assuptions?

CodePudding user response：

Unity using ECS, which means

Things are divided into entities and component, when entities are gameobject and components are classes that are attached to this script.

You just need to do this

PowerupWidget yourWidget = p.GetComponent<PowerupWidget>();
