Hitting in an area

I'm trying to make a custom bomb script that hits in an area. but i'm not totally sure on what all of the math functions we can use. anyone care to fill me in on some of the ones i should be using? also would i be entering this into a triggeraction, or something else?

Are you familiar with the distance formula?

If not Google it and familiarize yourself with it, it's quite useful.

You don't really need to understand it in your case though.

PHP Code:


		
			
function hit(x, y, radius) {

  for (temp.pl : findNearestPlayers(x, y)) {

    if (dist(x, y, pl.x, pl.y) <= radius) {

      pl.trigger("hit");

    }

  }

}



function dist(x1, y1, x2, y2) {

  return (((x2 - x1) ^ 2) + ((y2 - y1) ^ 2))) ^ 0.5;

}
