Er, so.  
I want to make my own custom crosshair. I've managed to disappear the default crosshair. but now, i need to add my own. 
My concept is to make a red dot display in right CENTER of the screen. The red dot will be a Dxline (or call it a dot  ) 
So, i need help with 2 things. : 
1. How can i make it appear always? like, i don't need the crosshair only when we aim, i want it to be their everytime. 
2. What are the co ordinates of the Center of the screen? (0,0)  ? 
Thanks in Advance.
