Input.mousePosition to ScreenToWorldPoint
Hey I am facing some problems with ScreenToWorldPoint casting, if you could help me.
Vector3 mouspos = new Vector3 (Input.mousePosition.x, Input.mousePosition.z, Input.mousePosition.y);
mouspos = Camera.main.ScreenToWorldPoint(mouspos);
Instantiate (obj, mouspos, Quaternion.identity);
So basically what I want to do, is to use the mouseposition and to instantiate an object only on x,z axis, but it's not working.
If I am just using
Vector3 mouspos =Input.mousepoint;
mous.pos.z = 5.0f;
mouspos = Camera.main.ScreenToWorldPoint(mouspos);
Instantiate (obj, mouspos, Quaternion.identity);
With this snippet of code, it will work, but this will place my object on x and y axis.
Would really need a little bit of help ^_^

Try using the following, it creates a ray in world space that lies on the pixel the pointer is on and intersects it with a plane that lies on y=0.
Plane plane=new Plane(Vector3.up, Vector3.zero);
Ray ray=Camera.main.ScreenPointToRay(Input.mousePosition);
float distance;
if(plane.Raycast(ray, out distance)) {
Vector3 point=ray.GetPoint(distance);
Instantiate (obj, point, Quaternion.identity);
}
edit: good catch!
Yes! it's working. Please edit your answear.
Instantiate (obj, mouspos, Quaternion.identity);
change mouspos with point and I will mark your answer as good.
