How do I add forward velocity to a Rigidbody2D?
I am creating a 2d game and need to make projectiles that shoot towards were you clicked. I was able to make the projectiles spawn in and point at the mouse, but am unable to add forward velocity allowing them to shoot in the right direction. I have tried using the code Rigidbody2D.velocity = Vector2.up * 10; but this just led to the objects launching strait up instead of forward. I tried using Vector2.forward, but then the object wouldnt move at all. I also tried Rigidbody2D.AddForce(Vector2.up * 500); but this brought up the same problems.
Use transform.forward instead. vector3.up use global position so it doesn't care where you're object look at. transform.forward use a local position which basically mean the x,y,z changes on rotation.
This still didn't work. I'm assuming because its in 2d and transform.forward uses vector 3. In case there is something else wrong with my code that I don't know of that is preventing this from working I am putting the section of code that spawns the rocket and the one that is supposed to launch it.
void Shoot()
{
//Create rocket
GameObject rocketDuplicate = Instantiate(rocket) as GameObject;
Vector3 cursorPositon = Camera.main.ScreenToWorldPoint(Input.mousePosition);
rocketDuplicate.transform.position = new Vector2(player.transform.position.x, player.transform.position.y); ;
Vector2 direction = new Vector2(cursorPositon.x - rocketDuplicate.transform.position.x, cursorPositon.y - rocketDuplicate.transform.position.y);
rocketDuplicate.transform.up = direction;
Rigidbody2D rocketForce = rocketDuplicate.GetComponent<Rigidbody2D>();
//Shoot rocket
rocketForce.velocity = transform.forward * 10;
}
just set it to transform.right or transform.up because it's 2D
