removing entities from an entity list

I'm have an entity list based on a couple of factors, what im trying to do is run trough that list and based on a max amount of entities (mobs) set delete some of the entities. this is what I currently have:

Code (Java):

World world = Bukkit.getWorld(plugin.getConfig().getString("world"));
                        Location location = new Location(world,
                                plugin.getConfig().getInt("x"),
                                plugin.getConfig().getInt("y"),
                                plugin.getConfig().getInt("z"));
                        plugin.saveConfig();
                       
                        double radius = plugin.getConfig().getInt("radius");
                        List<Entity> near = location.getWorld().getEntities();
                        for(Entity e : near) {
                            if(e.getLocation().distance(location) <= radius && e.getType() == org.bukkit.entity.EntityType.SNOWMAN) {
                                for(int i = 0; i < near.size(); i++) {
                                      if( i >= amount) {
                                         
                                            Entity last = near.get(near.size() -1);
                                            last.remove();

this doesn't work however, I can do system.out.println(last); and that will print out the mobs in the console so I know that part works but iterating trough the list and removing the last item of that list till the list.size is under a given constant doesn't seem to work, does anyone have an idea on how to approach this?

 

no you see i don't want to remove all the entities, i want to set a max amount of entities in an area, so if i set it to 20 and there are 32 mobs it needs to kill 12

no that just gives a null error

 

could you give an example related to my code, i've never used iterators

 

okay, so i do:

Code (Java):

    Iterator<String> j = j.iterator();
                                        while (j.hasNext()) {
                                            String s = j.next(); // must be called before you can call i.remove()
                                            if (e.getLocation().distance(location) <= radius
                                                    && e.getType() == org.bukkit.entity.EntityType.SNOWMAN && j >= amount) {
                                            j.remove();
                                        }
                                    }

I see how it loops trough every item, but it's giving me an error on j.iterator saying its undefined

 

Right I got the hang of this now, looking goodone more thing: currently i get the error "getNearbyEntities is undefined for the type world"

Code (Java):

                    World world = Bukkit.getWorld(plugin.getConfig().getString("world"));
                        Location location = new Location(world,
                                plugin.getConfig().getInt("x"),
                                plugin.getConfig().getInt("y"),
                                plugin.getConfig().getInt("z"));
                        plugin.saveConfig();
                        double radius = plugin.getConfig().getInt("radius");
                        List<Entity> entities = world.getNearbyEntities(location, radius, radius, radius);
                                Iterator<Entity> i = entities.iterator();
                                while (i.hasNext()) {
                                    Entity entity = i.next();
                                    if( entities.size() > amount) {
                                    i.remove();
                                    }
                                }

 

bump
?

 

"The method getNearbyEntities( location, radius, radius, radius) is undifined for world"

 

not even compiling yet, just in eclipse.

Code (Text):

 List<Entity> entities = world.getNearbyEntities(location, radius, radius, radius);

gives the error...

 

does this method work with 1.8 though? cause otherwise I need to find a different way

 

Cause there are very specific gamemodes that are extremely popular and require features no longer supported with newer versions. But thats besides the point. Does the getNearbyEntities method work with a later 1.8 version or is it specifically a later update feature?
