Mobs Spawn and Lags

Hello everyone, Im trying to create kind of MineZ zombies plugin Ive got my extended entity and I would like to spawn him in the world, but I would like to spawn that entity more inside towns (so like in big town = lots of zombies , small town = less) ... how would I do that?
and for the lags, I have 3 delayed tasks that keep call themself as long as the player online (3 delayed tasks that run once in 190~210 ticks per player) and when Im on my testing server, after 1~3 mintues, Im getting PermGen error... Im calculating in this tasks the percentage of player health, taking XP levels from player, and taking XP from the bar of the player.. so my questions is :
- Is it like that because my computer sucks? (My computer isnt the best, I geuss its because of it? )
- Should I make 3 repeating delayed tasks for ALL players that online? instead of running 3 tasks per player? however then the server would have to do more calculations in same time...

Another question : Im using CustomEntityType class to extend and register custom NMS entities, I would like to spawn normal vanilla entities aswell, not only the NMS ones, how can I do that? since its replacing all vanilla entities with the NMS ones

 

Bump

 

Instead of using 3 delayed tasks you can use one SyncRepeatingTask

 

GameplayJDK Thanks, I may use it, but is it better? since the server have to calculate more stuff in same time.

 

It won't increase your servers performance, since it uses a new thread (Runnable).

 

GameplayJDK Thanks! any idea about the mob spawn?

 

Do

Code:java

 
player.getWorld().spawnEntity(new Location(player.getWorld(), x, y, z), EntityType.ZOMBIE);
 

to spawn a zombie at the location x, y, z

 

GameplayJDK Thanks, however this isnt my problem :/, Ive extended EntityZombie and want to set the zombie spawn rate higher in some places... I have no idea how to do that... and what is better? creating a delayed task that keep call itself in a method , so like :
public static void method(){
for(player p : getOnlineplayers()...){
p.setLevel(p.getLevel() * 100 / 20 + 7);
}
//200 ticks delay';
method();
}

or doing repeating task?

*Note that the code above isnt true, made it now for illustrate.

Better use a SyncRepeatingTask, I think these repeating tasks were made for these cases.

On spawning rate:
You can write a config with locations in it, the percentage of higher spawnrate, and the radius. Then you can querys 3D from x, y, z:
-radius to +radius
around the location
with the spawrate of [insert here]

A function you can rewrite for that: http://forums.bukkit.org/threads/looping-through-blocks-in-a-radius.237409/#post-2316131

 

GameplayJDK Il try that mob spawn soon, whats the diffrents between all the repeating tasks there is? is it the best (performance side) to use SyncRepeatingTask?

I don't know what exactly the differences are, but as said, a syncRepeatingTask is Made for the case, that you wann to repeat something. Using the repeating one is just less coding, I think.

 

GameplayJDK Il use it then but, this code do the same thing no?

Code:java

        BukkitRunnable task = new BukkitRunnable(){
            @Override
            public void run() {
 
            }
        };task.runTaskTimer(Main.getPlugin(), 5, 5);

Looks like it would do the same. (I've not used a BukkitRunnable before, I used the scheduleSyncDelayedTask.)

 

GameplayJDK Okay, thanks for help!
