Solved find number of players in area

hey, im trying to figure out a way to see the amount of players in a certain area, i cannot figure this out please help

 

loop trough them
if (player's location in the certain area)
do your stuff

if that area is only one chunk, you could do Chunk#getEntities()

 

@mcdorli thanks ill try that

@mcdorli how does one use loops for this 3:

for (Player player : Bukkit.getOnlinePlayers())
Please learn java, foreach loops are very basic part of it.

 

@mcdorli ah okay, thanks i haven't coded in a while and forgot some things xD. i still dont get how to see if there with in a 50 block radius of a location

 

pythagoras theorem (extended) if (x*x + y*y + z*z <= r*r), where x, y and z are the x, y and z distances from the location, and r is the radius

 

@mcdorli where do i put the location??

 

You have a location? then just #Location.distance(Location location) or something like that

 

@mcdorli so this will work if " l " is my location

Code:

if (p.getLocation().distance(l) < 50)

 

Yup

@mcdorli ahh ok, but if i created a int and set it to " 0 " and added 1 to it every time if found someone in that radius wouldnt it just stay 0?

 

If there's someone in that area, then probably not. I think i don't understand the question

 

@mcdorli i need an int to equal the number of players within 50 blocks of the loaction

 

As you mentioned, set it to 0 first, then every time it finds someone, add one to it.

 

@mcdorli ahh thanks i thought it through and figured it out, thanks again so this should work:

Code:

for (Player player : Bukkit.getOnlinePlayers()) {
                            if (p.getLocation().distance(l) < 50) {
                                players = players + 1;
                            }
                        }
