Kill a entity from code

[ElTotisPro50]

so i have a String in my code with a name, for example(String name = "CowDude") and i have a entity with a nametag called "CowDude", so if i right click my item i want to kill all the entities named CowDude

use Level#getEntitiesOfClass to get all Entities of the Type you want to run this action,
then loop through the list you get, and check if the name of the Entity equals your String (you can get the name from the Entity via Entity#getName then Component#getString),
do this in Item#use inside your Item class

i want to kill ANY entity with the CowDude name, not just cows or a specific entity, and i saved in a string the entity name with .getCustomName(), so once o have the name how can i kill the entities?

Call the hurt method on an Entity instance.

ok, so HOW I HURT ALL ENTITIES WITH THE NAME CowDude(is saved in a string: String name = "" + entity.getCustomName();)

example:

String name = "" + entity.getCustomName();

if(entity.hasName == name)

{

     hurt all entities with "name"

}

[ElTotisPro50]

is there a way to call a method for a entity for example: entity.hurt() but only for all entities with a specific name

EXAMPLE: Entities affected(with name COW)=

cow with name COW=yes

creeper with name CoW=no

player with name PL=no

player with name COW=yes

 

that "yes" is for affect all those entities(named COW) with a entity method

ok this should work:

String name = "CowDude";
        Entity entity = playerIn.getEntity();
        if(entity.getName().equals(name))
        {
            entity.setFire(5);
        }

just 1 more thing, how do i get all entities in the world, this: Entity entity = playerIn.getEntity(); doesnt work for obvious and i cant find a world.getAllEntities or something like that

Please is the only thing left

Level#getEntities().getAllEntities

Note that you should really avoid looping through all entities if you can avoid it.

doesnt exist world.getEntities().getAllEntities (i think you put Level because it is un 1.17 but im in1.16.5)

and how can i "avoid looping throught all entities"

You did not mention the Minecraft version, hence I figured you were using the latest one (1.18.1).

In 1.16.5 you can use ServerWorld#getEntities.

Pick a region that you search or pick a base entity class. Or better, even both.

Expand  

oh shoot you are right i didnt mention the minecraft version, but 

ServerWorld serverWorld = null;
String name = "CowDude";
Entity entity = serverWorld.getEntities(); //this line is giving an error

that line of Entity entity = ... is not working(Incompatible types. Found: 'java.util.stream.Stream<net.minecraft.entity.Entity>', required: 'net.minecraft.entity.Entity') is saying i cant use Entity that i need to use Entity, wtf

The fact that you do not know this proves that this is untrue:

well then tell me, as i can see with my eyes is asking for Entity, im passing Entity

Incompatible types. Found: 'java.util.stream.Stream<net.minecraft.entity.Entity>', required: 'net.minecraft.entity.Entity'

How is founding java,util.stream.Stream, im importing import net.minecraft.entity.Entity;

maybe is a dumb error but i have no clue of why is this(im finishing java but this error is related to minecraft i think)

I'm sure the server already exists; after all, it would have to in order for you to join the world...
