1.14.4 Custom Summon Command

Hello, i want to create a Command where you can Spawn All Entitys and you can enter an amount.

Example:

/sm list -> Shows a List of all Entitys
/sm <EntityName> <Amount> -> Spawns Entitys
/sm remove <Radius> -> Removes all Entitys in the Following Radius

The thing is i dont know How to send the Player a list of all Entitys (Example Viedeo (4:47)) and i dont know how to make that the player really removes the Entitys in this Radius.

Thanks to all Helps.

 

I dont want to get Nearby Entitys i want to get a list of all aviable entitys in minecraft like in the example viedeo

 

In this viedeo he uses this:

Code (Java):

 String text = ""; byte b; int i; EnumParticle[] arrayOfEnumParticle;
    for (i = (arrayOfEnumParticle = EnumParticle.values()).length, b = 0; b < i; ) { EnumParticle pa = arrayOfEnumParticle[b];
      if (text.equals("")) {
        text = pa.name();
      } else {
        text = String.valueOf(text) + ", " + pa.name();
      }  b++; }
 

And i want to use it like this but instead of Particle names Entity Names

 

When i make

p.sendMessage("Entity Liste: " + EntityType.values());

it shows me this in chat: http://prntscr.com/qshp96

 

I got it, but i have thinked i know how to spawn the Entity that i Type in the chat but i dont know it makes an error and how does i set the amount ?

I have used this: p.getWorld().spawnEntity(p.getLocation(), args[0]);

 

EntityType entity = args[0];
p.getWorld().spawnEntity(p.getLocation(), entity);

Eclipse tell me: Type mismatch: cannot convert from String to EntityType

 

Can you please tell me what i can do that this is goind to function

 

Ok a BIG thanks for that!
Now i have a problem. I looked over the Javadoc and im not able to find a way to define the amount of entitys that be spawn.

 

Sorry for that we post it at the same time ^^

 

Sorry for the dumb question but how do i do a loop for a certain amount of times ?
