The Left-hand of an assignment must be a variable, property or an indexer.

Hola!
Tengo un problema en mi script y es el siguiente:


using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Bird : MonoBehaviour {


private bool isDead;
public Rigidbody2D rb2d;
public float upForce;



private void Update () {
if (isDead) return;
if (Input.GetMouseButtonDown(0)){
rb2d.velocity = Vector2.zero;
rb2d.AddForce = (new Vector2(0, upForce));
}

}
private void OnCollisionEnter2D(Collision2D collision){
isDead = true;
}


}


Me marca esa linea con el problema "The Left-hand of an assignment must be a variable, property or an indexer."
¿Alguien puede ayudarme? Se lo agradeceria muchisimo, gracias de antemano.

 

Use code tags. The forum also speaks English.

By using

rb2d.AddForce = (new Vector2(0, upForce));

you're saying that AddForce will EQUALS this new thing, which makes absolutely no sense because it is not a variable field that you can define or assign in that way.

Instead, understand that AddForce is a METHOD and you need to call it and pass in your force as an argument.

rb2d.AddForce(new Vector2(0, upForce));

 

Thank you so much!!! you are my hero xdxd
