[2D] Problem With Mouse Follow Object

[DMCH]

Hi,

Having a problem with getting a game object to follow the mouse. I’m trying to show the player the range of turrets, so when they start placing one, this object with a circular texture follows the mouse.

The answer here brought me part of the way, but every time the mouse enters the lower half of the screen the circle disappears. This is the code I’m using in the update loop of the object that is following the mouse:

temp = Input.mousePosition;
temp.z = this.transform.position.z - mainCamera.transform.position.z;
transform.position = mainCamera.ScreenToWorldPoint(temp);

I’m using the X + Z axes, with Y = 0. Any advice on how to solve this? Thanks

u must use mouse raycast for
something like this add this to ur update func

Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

GameObject urOBJ=GameObject.FindWithTag("urobjTAGname");
if( Physics.Raycast( ray,out hit) )

		{
                      if(urOBJ)

{

              urOBJ.transform.position=new
Vector3(hit.point.x,hit.point.y,0); 
}
