Set Instantiate Velocity and Location C#

Questions & Answers
1

I have a script to instantiate a knife for the player to throw. Right now, when I push the key, the knife just falls from the middle of the screen straight down. I need the knife to appear in front of the character and launch forward from whatever direction he is facing. How can I do this? (PS: I’m using C#) Thanks ahead of time.
My code:

void Update () {
		if (Input.GetKeyDown ("f")) {
			GameObject myKunaiInstance =
			Instantiate (Resources.Load ("Kunai"),
				             direction = (target.position - transform.position).normalized
			            new Vector3 (1, 1, 1),
			            Quaternion.identity) as GameObject;

		}

Edit: I’ve been able to control the position with transform.TransformPoint(Vector3.forward * 20) but it doesn’t face the same direction of the player (it’s always facing right), and I still don’t know how to change the velocity to make it lung forward.

Please, watch the tutorials about Physics in Unity, you will find many answers here.

If you want your knife to face a specific direction, you will have to use the following function :

public static Quaternion LookRotation(Vector3 forward, Vector3 upwards = Vector3.up);

See doc : Unity - Scripting API: Quaternion.LookRotation
