Hi,
I have a prefab object called “Meteor”, which is instantiated randomly at the right edge of the screen using a coroutine. The meteor is instantiated through another script, named “meteorController”, to prevent clones from instantiating themselves. The script is attached to a gameobject with the same name. After MeteorPrefab is instantiated, I want to give it force towards another object, called “Spaceship”. I’ve tried doing it using AddForce with Impulse as the force mode, but it’s not working: the meteors are instantiated properly but they aren’t moving at all, although no error messages are displayed. The MeteorPrefab’s rigidbody is set to “dynamic” and it has a mass value of 1.
I’m new to #c. maybe something is wrong with my code?
Help would be appreciated.
Thanks
The meteorController script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class meteorController : MonoBehaviour
{
public GameObject MeteorPrefab;
public float timer = 5.0f;
private Vector2 screenBounds;
public Transform spaceship;
public Rigidbody2D rb;
public float force = 100.0f;
void Start()
{
screenBounds = Camera.main.ScreenToWorldPoint(new Vector3(Screen.width, Screen.height, Camera.main.transform.position.z));
StartCoroutine(Meteor());
Debug.Log(screenBounds);
}
private void SpawnMeteor()
{
GameObject spawn = Instantiate(MeteorPrefab) as GameObject;
spawn.transform.position = new Vector2(screenBounds.x, Random.Range(-screenBounds.y, screenBounds.y));
rb = spawn.GetComponent<Rigidbody2D>();
Vector3 direction = spaceship.position - transform.position;
float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
rb.rotation = angle;
rb.AddForce(spawn.transform.forward * force, ForceMode2D.Impulse);
}
IEnumerator Meteor()
{
while (true)
{
yield return new WaitForSeconds(timer);
SpawnMeteor();
}
}
}
Here’s a screenshot of the MeteorPrefab’s Rigidbody2D component:
