How do you get a players location from 12 blocks?

So I am making a plugin that if you have a stick, it will heal any player within 12 blocks.

So this is what I am trying to do.

You get the player location and then you + 12;

It maybe incorrect. But can someone help me on this.

 

@xXCapzXx Where you add the '12'? x? z? It can work but it will be an absolute pain especially for diagonal locations. For that reason bukkit has a method in the "Location" class called "distance" so if you want to check the distance between two locations it is the best to use.
But your question has a very simple answer comming from the Entity class. It is the method called "getNearbyEntities" this returns a List of entities in the range you specify (like 12x 12y and 12z) then you need to loop though all of them to check if they are players and perform anything on them!

 

Thanks, but can you do the line of code for it? I am not sure what you mean but I know in the same time. Can you type the code?

 

@xXCapzXx im afraid i cant (specifically i can but i dont want to) In these forums we are not spoonfeeding people because we understand that what is most likely to happend afterwards is a copy - paste action by the one(s) asking that will most of the time result in no knowledge gain therefore we usually let people develop their skills by trying pieces of code themselves and when they reach the dead end we are here to give them a litle walktrough but not the entire solution.

So i wont do the code. However i will point you twards the right direction to find the solution, its you coding afterall not me.
Take a look:
http://d.ld.lc/interfaceorg_1_1bukkit_1_1entity_1_1Entity.html
(check the "getNearbyEntities" method)
https://docs.oracle.com/javase/tutorial/java/nutsandbolts/for.html
(check the 'forEach' loop, or how to iterate over Iterable implementations)
http://www.java2s.com/Tutorial/Java/0060__Operators/TheinstanceofKeyword.htm
(read this whole thing)

All you need to know to do this piece of code is listed above ^
I didnt include the If statements assuming you are already aware of them.
good luck, if and when you reach a code dead-end we will be here to help you with your code

 

I still am not sure.
I know its kind of spoon feeding, but I really need this done.

 

@xXCapzXx And still i cant do the code :- ) What are you unsure about? Have a try its easyer than you think and if you het stuck ill be here, send me your code (in this thread) and i will do my best to help.

 

I really need help with this please.

Code:

public void onEnable() {

Bukkit.getServer().getPluginManager().registerEvents(this,  this);

}


@EventHandler

public void click(PlayerInteractEvent e) {

Player player = e.getPlayer();

Player target = e.getPlayer();

Location loc = player.getLocation();

if(e.getAction() == Action.RIGHT_CLICK_AIR) {

if(e.getItem().getType() == Material.INK_SACK) {


}


}

}



}

When you click an ink sac, it will heal a player your looking at of the distance of 12 blocks.
I want to get the distance first of Player
And then get the target from the distance of 12 blocks
then heal them
if they are not looking at the target if(target == null)
player.sendMessage("cant find target);

That is my plan.

 

@xXCapzXx
All you have to do as @mine-care has been telling you is to make a for loop that loops through all the entities with getNearbyEntites(x, y, z)

 

Code:

for(int i = 0; i > 12; i++) {

player.getNearbyEntities(12, 12, 12);

}

Like that?

Nevermind I did it.

But is this correct?
The player you are looking at within 12 block range, gets healed 4 hearts?

code:

Code:

public void onEnable() {

Bukkit.getServer().getPluginManager().registerEvents(this,  this);

}


@EventHandler

public void click(PlayerInteractEvent e) {

Player player = e.getPlayer();

Player target = e.getPlayer();

Location loc = player.getLocation();

if(e.getAction() == Action.RIGHT_CLICK_AIR) {

    if(e.getItem().getType() == Material.INK_SACK) {

for(Entity en : player.getNearbyEntities(12, 12, 12)) {

player.sendMessage(ChatColor.GREEN + "You healed" + (en instanceof Player ? ((Player) en).getName() : en.getType().name()));

if(en instanceof Player) {

((Player) en).setHealth(8);

}

}

}

    }

Why is target needed?

 

Oh, thats useless, dont mind that.

 

@xXCapzXx Please tell me the code isn't indented like that and the copy & pate screwed up.

 

Here's a nice utility method for you: https://github.com/CodeLanx/Codelan...om/codelanx/codelanxlib/util/Players.java#L83

Usage is fairly straightforward:

Code:java

Player orig = /* your player at the center */;
//Map of players in range to the distance away they are (could apply a multiplier based on this)
Map<Player, Double> players = Players.getPlayersInRange(12, orig);

 

Awesome code, I'll use it.
I am not sure what I sure put in //Map of players in range to the distance away they are (could apply a multiplier based on this)?

 

That would be the Map below it, the comment just explained what it was.

 

Sorry, but it won't be as easy as adding.
You could use nearbyEntites, but I would use distanceSquared(12*12)
