从组件gameObject访问容器gameObject

Question

1. I created a GameObject and named it "sensor". I then added a BoxCollider and a script (script_sensor) to sensor.

2. Then I created another GameObject and named it "taxi". I added a script (script_taxi) to taxi and created a public Collider2D in the script.

3. Then I assigned the sensor GameObject to taxi's public Collider2D .

4. And now, i want to access script_taxi from script_sensor .

Basically, How can i access script_taxi (Box 1 on the image), from script_sensor (Box 2)?

Check the image to understand better.

Ps: When i spam taxi prefabs, every sensor object should be able to find it's own container gameobject(taxi).

Answer 1

If you want to access script_taxi from script_sensor , you need some type of reference to script_taxi inside script_sensor . You can then use GetComponent . You could also use a variation of GameObject.Find , however these calls can be expensive.

public class script_sensor : MonoBehavior {
    [SerializeField]
    private GameObject taxi;

    private script_taxi taxiScript;

    void Start() {
       taxiScript = taxi.GetComponent<script_taxi>();
    }

}

Also it is recommended to follow C# naming conventions .

script_sensor => Sensor

script_taxi => Taxi

public Collider2D col; => [SerializeField] private Collider2D col;

Answer 2

Or with GameObject.Find() to find the taxi GameObject like this:

    script_taxi taxi;

    void Awake() 
    {    
        taxi = GameObject.FindWith("taxi").GetComponent<script_taxi>();
    }
