AddForce rigidbody 2d not moving object
I wanted to shoot a projectile from Shooter transform's position, but AddForce is not moving the object at all. The rigidbody 2d on the projectile is set to dynamic, simulated is on and mass is very low. I am not able to find the problem.
Here is the code:
public Vector2 forceVector;
public GameObject projectile;
public Transform Shooter;
public float thrust = 10;
private void ShootProjectile(Vector2 forceVector) {
Instantiate(projectile,Shooter.position,Quaternion.Euler(0,0,0));
projectile.gameObject.GetComponent<Rigidbody2D>().AddForce(forceVector*thrust,ForceMode2D.Impulse);
}
void Update() {
if (Input.GetKeyDown(KeyCode.H)) {
ShootProjectile(forceVector));
}
}
You are trying to AddForce to your project prefab and not to your instantiated prefab, what you should be doing to make this work is this:
private void ShootProjectile(Vector2 forceVector)
{
// Instantiante and store it as temporal Rigidbody2D
Rigidbody2D projectileRbody = Instantiate(projectile, Shooter.position, Quaternion.Euler(0, 0, 0)).GetComponent<Rigidbody2D>();
// AddForce to the stored Rigidbody2D
projectileRbody.AddForce(forceVector * thrust, ForceMode2D.Impulse);
}
This method works, but it's not a good way to handle this. What you could be doing is controlling the projectile with its own class and simply calling a method that could be called Launch() that adds a Force internally (that way you can have all sort of projectile with different thurst and your Shoot class simply Launch them.
@tadadosi Thank you so much, this fixed my problem!
Np! Glad I could help!
