Getting object to follow mouse position along X axis only

Questions & Answers
1

I am trying to move my character along the X axis using my mouse cursor. I have searched around and found some scripts such as unifycommunity.com

However, these are all moving the object to the exact position of the mouse, at the moment, I have it so that it moves up when the spacebar is pressed and falls to the ground when it isn’t and i’d like to keep this for the Y axis movement, but get the object to follow my mouse’s X axis co-ordinates for the objects movement horizontally. But I can’t figure out a way to do this without the object moving to the mousePosition Y and X co-ordinates.

Any help would be appreciated.

You’ll need to convert the mouse position from screen area to world position, using something like Camera.ScreenToWorldPoint() , this exact code is untested but I’Ve used this before IIRC:

function Update():void
{
    myObject.transform.position.x = Camera.main.ScreenToWorldPoint(Input.mousePosition).x;
}

i´m also new to unity and stuff, but what you can try to do is taking only the x position of the mouse and set it to the objects transform.position.x

privater var mousposX;
var yourObject: Transform;
function Update () {
 
mouseposX = Input.mousePosition.x;
yourObject.Position.x = mouseposX;


}

i´m not sure if this helps you but maybe it will work with something like this

I did something similar for someone recently , here is that question : fire-at-mouse-position-fps

Here is a script re-written for your purpose. Make sure you read it, the raycast is what is doing the work , and answering your question ( as suggested by @BY0LOG1C ).

private var mouseposX : float;
private var rayHitWorldPosition : Vector3;
var yourObject : Transform;

function Update () {
	if (Input.GetKeyDown(KeyCode.Mouse0))
	{
		// raycast
		var rayHit : RaycastHit;
		if(Physics.Raycast(Camera.main.ScreenPointToRay(Input.mousePosition), rayHit))
		{
			// where did the raycast hit in the world - position of rayhit
			rayHitWorldPosition = rayHit.point;
				print ("rayHit.point : " + rayHit.point + " (rayHitWorldPosition)");
			mouseposX = rayHit.point.x;
		}
		yourObject.position.x = mouseposX;
	}
}

Wouldn’t adding a rigid body and constraining it to the X coordinate be easier?
