Question by MithosKuu · Sep 10, 2012 at 09:18 AM · 2dprojectileshootside scroller

Fire a Projectile towards a specific object?

I'm making a 2D Side Scroller and I'm trying to launch a projectile from an object called "StrawSpawn" towards and object called "Target" at a speed of 20.

With my current code my projectile always fires off to screen right at a slight angle and nearly too fast to see, regardless of where "StrawSpawn" and "Target" are located relative to each other.

Can someone take a look at my code and tell me what I'm doing wrong? Thanks.

 var projectile : Rigidbody;
 var speed = 20;
 
 function Update () 
 {
     // Put this in your update function
     if (Input.GetButtonDown("Fire")) {
 
     // Instantiate the projectile at the position and rotation of this transform
     var clone : Rigidbody;
     clone = Instantiate(projectile, GameObject.Find("StrawSpawn").transform.position, transform.rotation);
 
     clone.velocity = transform.TransformDirection (GameObject.Find("Target").transform.position * speed);
 
     Destroy (clone.gameObject, 3);
     }
 }

After asking on the forums, this is the working code I ended up with for anyone else looking to do something similar:

 var projectile : Rigidbody;
 var speed = 20;
 
 function Update () 
 {
     // Put this in your update function
     if (Input.GetButtonDown("Fire")) {
 
     // Instantiate the projectile at the position and rotation of this transform
     var clone : Rigidbody;
     clone = Instantiate(projectile, GameObject.Find("StrawSpawn").transform.position, transform.rotation);
 
     clone.velocity = (GameObject.Find("Target").transform.position - transform.position).normalized * speed; 
     clone.velocity.y=0;
 
     Destroy (clone.gameObject, 3);
     }
 }
