Why does my player disappear now?

Scripting

Below, is the code that I attached to the gameObject that I wanted to affect.

using UnityEngine;
using System.Collections;

public class Drag : MonoBehaviour {

    private Vector2 screenPoint;

    void OnMouseDrag()
    {
        Vector2 curScreenPoint = new Vector2(Input.mousePosition.x, 0);
        Vector2 curPosition = Camera.main.ScreenToWorldPoint(curScreenPoint);
        transform.position = curPosition;
    }
}

Originally, I had set “Vector2 curScreenPoint new Vector2(Input.mousePosition.x, Input.mousePosition.y);”; however, I changed the y parameter to 0 because I didn’t want my gameObject to move in the y direction only the x direction.

Thanks in advance.

Check to see if the Z position is zero and behind your camera.

Maybe is that setting curScreenPos.y = 0 doesn’t mean you don’t have a change in this position. In this case your GameObject will be set at the bottom of your screen.

if you want, that your drag only changes X Position of your current transform you have to do → 

void OnMouseDrag()
{
   Vector2 curPosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
   transform.position = new Vector3(curPosition.x, transform.position.y, transform.position.z);
}

so your drag will only affect x

Thank you, this worked great. Now I need to figure out how to make my character move in this way when I click and drag on any part of the screen. If I attach this script to the main camera and rewrite this script to move the character from there, would that work?

Yes it would work, if you set the curPosition x and y aos transform.position your charakter will follow your mouse.
