Alive players indicator, kills indicator, anti camp ray and player kill sound

[hunterofdoom 1]

I need a box at the lower right side of screen showing: (In green) How many units did you kill

(In red) How many survivors are alive.

Also i need an anti-camp measure, where when you dont move to a 3 m radius in 30 seconds, a ray appears from you to the sky for 30 seconds

Thanks for helping a total newbie... i would like to learn scripting!!
