Simple Noob Question: Count, Set Up

I have a new project, where I am setting up Analytics, of which I am still kinda noobish.

If I create a Analyitics_Mng, where by it has functions I call at various points to update Analytics, example:

Code (csharp):

1.  
2.     public static void game_launched(){
3.         //sent via splash.
4.         Analytics.CustomEvent ("game_launched");
5.     }
6.  

I am wondering two things, with the format of the example above,....

a ) do I need to go into Dashbaord and create a "game_launched", parameter? If so, is it as a Funnel?
b) each time this function is called, will the Dashboard parameter, "game_launched", go up 1. So game_launched++?



Thanks
