So basically you can do it like this:

1

distance = math.sqrt(player(id1,"x") - player(id2,"x") + player(id1,"y") - player(id2,"y"))

You didn't "square" the variables:

1

distance = math.sqrt((player(id1,"x") - player(id2,"x"))^2 + (player(id1,"y") - player(id2,"y"))^2)

side1 = math.max(player(id1,"x"),player(id2,"x"))-math.min(player(id1,"x"),player(id2,"x")) side2 = math.max(player(id1,"y"),player(id2,"y"))-math.min(player(id1,"y"),player(id2,"y")) distance = math.sqrt(side1^2+side2^2)

You cant use math.sqrt on a negative number

I don't know, but my version worked normal for me.

player 1 X100 Y100

player 2 X200 Y300

sqrt(100 - 200 ^ 2 + 100 - 300 ^ 2)

sqrt(100 - 40000 + 100 - 90000)

sqrt(-39900 - 89900)

sqrt(-129800)

no number multiplyed by himself can be a negative number

example

2^2 = 2*2 = 4

-2^2 = -2*-2 = 4

@Vectar666 No, I didn't see them. Sry , I have problems with brackets when I make luas. Anyway, both codes should work.

and, I'd prefer math.abs instead of math.max with math.min.

Just a little less space eaten by it.

function math.dist(p1, p2) local x, y = player(p1, "x"), player(p2, "y"); local x2, y2 = player(p2, "x"), player(p2, "y"); return math.sqrt((y2-y)^2 + (x2-x)^2); end

Just call it with two player IDs.

Ex.:

1

dist = math.dist(1, 32);

Fudge cakes. It was late and I was tired, what can I say?
