How can I damage a player holding shift?

Note: Im new to Bukkit, and am working on my first plugin RN, so I may seem look like a noob.

So yeah. Im working on a plugin that turns you into an ironman, asked for help earlier, got a tip from a moderator, thx. Anyhow, he/she told me to work on damaging first, then particles, and I thought: Ok. Im just going to get another problem.

What I want is so that after you type my command, holding shift will damage the entity (If there is one) you are looking directly at (With 15 true damage). Here is what I got so far:

public boolean onCommand(CommandSender theSender, Command cmd, String commandLabel, String[] args)
{
if (commandLabel.equalsIgnoreCase("EquipIronman"))
{
Player thePlayer =(Player) theSender;
thePlayer.sendMessage(ChatColor.DARK_RED + "Equipping MK7... Complete.");

return true;
}
return true;
}
}

Now what I want to know is where and how do I type these 2 things (For the command, I think these are what I need)

PlayerShiftClickEntityEvent
^^To set off the command upon hitting shift

and this vvvvv

Player.getLocation().getDirection()
^^To get the direction the player is looking and another line of code for it to damage 15 True Damage (Which I do not know the code for that).

Any help please?

 

What have you tried?

 

I tried adding an "If" statement telling it to damage the player where the sender is looking

{
if (theSender Player.getLocation().getDirection() = getDirection.findEntity (findEntity) anEntity)
damage anEntity 15 true;

My friend told me to do something like that, it didnt really work.

 

@iScience
What you need to do is create a Repeating Task when the player sends the command. Each time the task runs, check if the player is shifting. If he is, check if there is a entity where the player is looking. If so, damage it.

 

Thx m8y

 

Do not blind cast. before casting theSender as a player, check if he is instanceof Player first

What you need to do is create a Repeating Taskcant extend it to when the player sends the command. Each time the task runs, check if the player is shifting. If he is, check if there is a entity where the player is looking. If so, damage it.[ QUOTE]Since I cant extend it to 2 different things, do you know how I can make it enable a class when the command is sent? That way I can have it extend to BukkitRunnable and JavaPlugin

 

You can. class MyClass extends JavaPlugin,MyOtherClass

EDIT: do

Code:

new BukkitRunnable() {your code here}

You do not need new classes.

 

Thx m8y

new BukkitRunnable() {

@Override
public void run() {
[Help Needed Here]

}

Ok I got that done. Where it says [Need Help Here], can someone tell me how it would get the direction, select the entity, and do damage to it (15 true) whenever someone presses shift? pls

This might help you.

Get the entities, loop through and check if they are in the line of sight https://hub.spigotmc.org/javadocs/s...html#hasLineOfSight(org.bukkit.entity.Entity)
then just damage that entity and return from the loop.

 

@iScience

1. First, you need to store the player variable somewhere
2. Using Player#getNearbyEntities(x,y,z), create a collection of all the nearby entities.
   
3. Get the player's direction using Player#getLocation().getDirection();
   
4. Create two radios, using X as the base. One will be the Z over x, and the other is the Y over X.
   
5. Create a for loop. i will increment by 0.25 untill it reaches a "max distance"
6. Using the two ration above, get the player's location and add onto it those ratios multiplied by i. This will create a straight line in the direction you're looking.
7. Loop through the collection from #2, and test if an entity is within 1 block of the location.

 

@Zombie_Striker You seem to know what you are doing.

Is this correct? I dunno...
new BukkitRunnable() {

@Override
public void run() {
getNearbyEntities(x,y,z);
{
((Player) getDirection()).getLocation() ;
}

}

private Player getDirection() {
[DamageEntity( )]
return void;
}

It underlined (x,y,z), along with "Void" and the last "]" (After Damage entity). If I did most of it correct, can you tell me
A) How to damage the player and
B) how to fix the mistakes if there are any

 

@iScience I have no idea what you're trying to do there.... You don't return void, no idea why you have [] why do you have DamageEntity? And x,y,z is not set.

This is why people need to know Java before jumping into an API. Please read: https://bukkit.org/threads/read-me-first-how-to-make-a-plugin-development-thread.395844/

 

@iScience
You should not make plugins unless you have learned Java. Either you came from another language, you have no knowledge or programming at all. Either way, you need to learn Java first.
