统一 3d 和 C#，如果游戏对象 != 这个

Question

I have this code:

public class Gravity : MonoBehaviour
{
    GameObject[] planets;

    // Start is called before the first frame update
    void Start()
    {
        planets = GameObject.FindGameObjectsWithTag("Planet");
    }

    // Update is called once per frame
    void Update()
    {
        foreach (GameObject planet in planets)
        {
            if (planet != this)
            {
                //do things
            } 
        }
    }
}

I have a problem with "if (planet.= this)..." what I expect to occur is that if planets[index] == the gameObject then "planet,= this" will return false? But this is not working, how can I fix it?

Answer 1

this is a keyword which referes to the instance of the current object, in this case a Gravity class, so each GameObject object is different from a Gravity instance. You can do something like this, to access the attached GameObject :

foreach (GameObject planet in planets)
{
   if (planet != this.gameObject)
   {
      // Do magic stuff...
   } 
}
