How do I add a pulling force?

Questions & Answers

So, my character is a ball, and you solve puzzles by pushing cubes, (and more) but if you push a cube or ball into a wall, you can’t move it. So I thought of adding a pulling thing, where is I press a button, it pulls objects to me, my problem, is that I can’t/don’t know how to do this. So could anyone help me with this?

Hey!
Not sure how your code looks like, but off the top of my head I have 3 possible solutions that may work.

  1. Make the object you want you ‘pull’ a child of the pulling object. A child will move as one with its parent.
  2. Use Vector2.MoveTowards.
  3. Add force in the desired direction.

<pre> //Set parent. if (Input.GetKeyDown(KeyCode.X)) { transform.SetParent(pullingObject.transform); } //In order to detach a child from a parent if (Input.GetKeyUp(KeyCode.X)) { transform.SetParent(null); } </pre>``<code><pre> //Vector2.MoveTowards. Should be place in a FixedUpdate/Update. if (Input.GetKeyDown(KeyCode.X)) { transform.position = new Vector2.MoveTowards(transform.position, pullingObject.transform.position, speed) } </pre>`



//Add force in desired direction.

//Negative X to move left, negative Y to move down.

//Move left for example:

transform.GetComponent< Rigidbody2D>().AddForce(new Vector2(-5f, 2f));


Hopefully this helps, good luck.
