Launch a arrow to a player

Hello
I got a question, How to make that you got a emerald block and if a player is in a range of 5 blocks that there will be an arrow shooted to the player, How to make that?

Thanks

 

ArthurHoeke You check if the player is 5 blocks within the range of an emerald block and then you spawn in an arrow.

 

jimuskin Yes but how to make this? With wich event etc?

 

One way would be using the player move event and checking the x, y and z and see if any of those come within 5 of the player.

 

You use a PlayerMoveEvent, and you check all around the player for an emerald block. If it finds one, then it shoots an arrow at the player from the block.

 

bubba1234119 Maurdekye Okay thx, Whats the code to check the cords of a player? something like p.getCordinats or something?

 

The method p.getLocation() returns the player's location.

 

Code:java

Entity en = event.getEntity()
Location location = en.getLocation();
            double radius = 5D;
            List<Entity> near = location.getWorld().getEntities();
            for(Entity e : near) {
                if(e.getLocation().distance(location) <= radius)
                    if(e instanceof Player){
                        Player pl = (Player) e;
                    Block b = xxx
b.doSomething();
                    } else {
                        return;
                    }
            }

 

Cammeritz what i have to put on block b = xxx?
The cords or something? And how ?

 

You can (for example) save the coords of the block in the config.yml or with an command, which saves the coords in the config.

 

We are not here to provide the code for you, we are here to help you. For the Block b = xxx, like Cammeritz has said, save the coords into a config and retrieve the block at those set coords. OR if you are using an emerald block, save the coords when the block is placed. Then, launch an arrow from the block's location targetting the player.

 

jimuskin he is right
