Vector2 MoveToward on HUD Canvas slow

Question

The Vector2. MoveForward function seems to be what I want. I already used it for an enemy instance that walks arround with a speed of 3 time.Deltatime. But now I have an text object on my HUD canvas that starts at my players gameobject.position and I want to move it towards an text object in upper middle of the canvas. The first thing that difference from the enemy situation is the speed that I needed to configure higher to about 10 time.DeltaTime instead of 3 .. for the same speed? It seems even slower when I upload it to my android device?? Even with 100 time.DeltaTime??? But eventually it comes to it's target position :) Does this have something to do with the canvas that can change it's scale??

First I aline the source Hud canvas text object to the position of the player character:

streakPointText.transform.position = Camera.main.WorldToScreenPoint(new Vector3(characterTrans.position.x, characterTrans.position.y, characterTrans.position.z));

When the text object is in position, I move it towards the other main text object on the canvas with the following code in the update ():

float step = speedStreakText * Time.deltaTime; streakPointText.transform.position = Vector2.MoveTowards (streakPointText.transform.position, timeTextTrans.position, step);

The vector3 only accepts 3 arguments not just 1, so I have to feed it with these 3 seperate values. The speedStreakText gets it's value from another function in another script. The strange thing is that I use the same function moveTowards on my enemy and it's not on the canvas. By just filling in on the enemy a value of speed = 3 it moves acceptable. For the canvas I have to put a value of almost speed = 150 and it's still not on the same speed... I beginning to believe it has something to do with the canvas that scales to fit the screen and that has some influence on the speed which degrades it with some factor?

To troubleshoot things I put a single object on my canvas and tried to move it to a other location on the canvas. But it's still slow moving. This is the code:

using UnityEngine; using System.Collections;

public class TestMoveTowards : MonoBehaviour {

 Vector2 targetPos;

 // Use this for initialization
 void Start () {
 
     targetPos = new Vector2 (0.0f, -25.0f);

 }
 
 // Update is called once per frame
 void Update () {
 
     float step = 3 * Time.deltaTime;
     transform.position = Vector2.MoveTowards (transform.position, targetPos, step);

 }

}
