How to place an object at the mouse position?

Question

How can I place a object to position where I clicked in just x,y axis not in z, I am trying to achieve it with

Vector3 mousepos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
object.transform.position = new Vector3(mousepos,mousepos);

but it does not seem to work, in fact the object doesn't even move.

new Vector3(mouspos,mousepos); This isn't valid syntax. There's no Vector3 constructor that takes two Vector3s as arguments. What is it you're trying to do with this? — DMGregory, Commented Dec 10, 2017 at 2:12

You need to reference the value, not the entire vector.

 Vector3 mousepos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
 object.transform.position = new Vector3(mousepos.x,mousepos.y,0);

\$\begingroup\$ Or, as the mousepos vector is not being recomposed... object.transform.position = mousepos \$\endgroup\$

\$\begingroup\$ I was pretty sure that was the case, but couldn't remember what the Z value would be on it \$\endgroup\$

\$\begingroup\$ Depends on your scene. IIRC, a ray is fired into the scene and returns the first point it hits a collider (or the camera's far plane). Ah, I was wrong. As Input.MousePosition will have 0 as the z component, then this method will only ever return the position of the camera. \$\endgroup\$
