Smooth Movement unity

Questions & Answers

Hi new to android development. I want to move a sprit to the point on my screen where touched. I have managed to do that but it jumps there. I know it has something to do with time.deltatime but I can’t figure it out.

this is what I have so far.

#pragma strict

var target : Transform;

function Update () {
	
	for( var touch : Touch in Input.touches)
	{
		
		if(touch.phase == TouchPhase.Began)
		{
			var ray = Camera.main.ScreenPointToRay (touch.position);
			var hit: RaycastHit;
			print("touched");
			if(Physics.Raycast(ray, hit))
			{
				if(hit.collider.tag == "GameController")
				{
					print("has Began");
					print(hit);
					target.position = hit.point;
				}
			}
		} 
	}	
}

You need to multiply the amount you want to move by deltaTime (time between frames) in order to ensure the object moves the same amount each frame, and therefore moves smoothly.

It sounds like you want to use Vector3.MoveTowards.

You could do something like this:

var targetPosition : Vector3;
var objectToMove : Transform;
var moveSpeed : float = 1.0;    
 
function Update () {     
    for( var touch : Touch in Input.touches) {
       if(touch.phase == TouchPhase.Began)
       {
         var ray = Camera.main.ScreenPointToRay (touch.position);
         var hit: RaycastHit;
         print("touched");
         if(Physics.Raycast(ray, hit))
         {
          if(hit.collider.tag == "GameController")
          {
              print("has Began");
              print(hit);
              targetPosition = hit.point;
          }
         }
       } 
    }  
    
    objectToMove.position = Vector3.MoveTowards(objectToMove.position, targetPosition, moveSpeed * Time.deltaTime);    											
}
