How to move direction of particle(s) emitted by ParticleSystem Shuriken

So, I have particle system that emit lot of particle(s). I want it after play for few seconds, all particle will come/moved into 1 object position. How can I achieved that?

It’s more easy if you create a prefab.

and use this code in your player

var shuriken : GameObject;
var throwShuriken = false;
var throwShurikenTime : float = 0;
var throwShurikenNumber : float = 0;

function Update()
///key pressed {throwShuriken=true;}
if(throwShuriken){
throwShurikenTime + = Time.deltaTime;
if(throwShurikenTime>=0.5){
throwShurikenNumber +=1;
clone = Instantiate(shuriken, transform.position, transform.rotation);
if(throwShurikenNumber>=10){
     throwShuriken=false;
}
}
}
}

to follow you create a script and attach to your shuriken

i’m portuguese “rotacao” it’s max rotation that your shuriken can do;
and “tempo” is the maximo time that shurikens are on the field;

var target : Transform;
var tempo : float =0;

function Update(){
tempo+=Time.deltaTime;

	transform.Translate(Vector3.forward*Time.deltaTime*speed);
	
	if(rotacao>=-40 && rotacao<=40){
	
	var relativePoint = transform.InverseTransformPoint(target.transform.position);
    	
    if (relativePoint.x < 0.0){
    	transform.Rotate(0, rotacaospeed*-1 , 0);
    	rotacao-=rotacaospeed;
    }else if (relativePoint.x > 0.0) {
    	transform.Rotate(0, rotacaospeed , 0);
    	rotacao+=rotacaospeed;
    }else{
    	transform.Rotate(0,0,0);
    }
    }

     if(tempo>=2){
           Destroy(gameObject);
      }

}
