Native Code

Is there a list of minecraft server native code anywhere? Or can anyone at least direct me to a commented entity thing? I've been trying to override mob classes and I can't get mob speed to change, but I'm not even sure if I'm overriding the right method. I also randomly get error

Code:

2012-11-24 23:26:49 [INFO] Skipping Entity with id Zombie

when a player logs on, but its random. And while it doesnt do anything harmful it lags
server
Below is where I iniatilize my custom mob

Code:java

 
try {
@SuppressWarnings("rawtypes")
Class[] args = new Class[3];
args[0] = Class.class;
args[1] = String.class;
args[2] = int.class;
 
Method a = net.minecraft.server.EntityTypes.class.getDeclaredMethod("a", args);
a.setAccessible(true);
 
a.invoke(a, mehZomboids.class, "Zombie", 54);
} catch (Exception e) {
e.printStackTrace();
this.setEnabled(false);
}
}
 

And below is my zombie class - which is using two constructors based on if I want specific hp or scaled on distance

Code:java

 
public class mehZomboids extends net.minecraft.server.EntityZombie 
{
Location loc;
public int cHealth = -543543;
int mHealth;
public mehZomboids(World world, Location location) 
{
        super(world);
        loc = location;
mHealth = (int) loc.distance(new Location(loc.getWorld(),0,64,0))/5 + 30;
cHealth = mHealth;
 
    }
public mehZomboids(World world, int hp) 
{
        super(world);
mHealth = hp;
cHealth = mHealth;
    }
@Override
public int getMaxHealth()
{
return 10000;
}
public int realHealth()
{
return mHealth;
}
public int currentHealth(){
return cHealth;
}
public void ondamage(int dmg){
cHealth = cHealth - dmg;
}
}
 

 

The base minecraft code is here:
https://github.com/Bukkit/mc-dev

 

can you give me the full code for MehZomboids (including imports)
https://github.com/Bukkit/mc-dev/blob/master/net/minecraft/server/EntityZombie.java

Just to make it clear for you, Zombies are spawned with a net.minecraft.server.World object only, so both constructors have the wrong argument count

 

So I have to spawn zombies with only 1 constructor?.... And I was thinking I had found a good solution to scaling hp ): Also thank you for source code I spent awhile looking for that.

 

If you override the original Zombie, yes there is only 1 constructor for that (sadly enough) but you could implement a setHealth method and use that to scale its health :3

 

Okay, that makes me sad but I guess it could be worse.

One last question, do I have to invoke again for every new Entity I make or can I just add

Code:

a.invoke(a, mehZomboids.class, "Zombie", 54);
a.invoke(a, mehSkeles.class, "Skeleton", (a #));
a.invoke(a, mehSpiders.class, "Spider", (a #));

?

the block of code should be good

 

K thanks for all your help!

Wait... nvm I'm getting this error now

Code:

which

Code:

Caused by: java.lang.ClassCastException: com.gmail.babmush.Adventurer.mobs.mehZomboids cannot be cast to com.gmail.babmush.Adventurer.mobs.mehSkeles

is the error but I'm never casting my zombies to my skeles?
below is damagehandler 77-98

Code:

public void applyDmg(Entity entity, int damage) {
switch (entity.getType().getTypeId()) {
case 54:
mehZomboids yourZombie = (mehZomboids)((CraftEntity) entity).getHandle();
yourZombie.ondamage(damage);
if (yourZombie.getRealHealth() <= 0) {
entity.getWorld().spawnEntity(entity.getLocation(), EntityType.EXPERIENCE_ORB);
ItemStack i = new ItemStack(Material.BEACON,27);
entity.getWorld().dropItem(entity.getLocation(),i );
yourZombie.setHealth(0);
}
case 51:
mehSkeles yourSkele = (mehSkeles)((CraftEntity) entity).getHandle();
yourSkele.ondamage(damage);
if (yourSkele.getRealHealth() <= 0) {
entity.getWorld().spawnEntity(entity.getLocation(), EntityType.EXPERIENCE_ORB);
ItemStack i = new ItemStack(Material.BEACON,27);
entity.getWorld().dropItem(entity.getLocation(),i );
yourSkele.setHealth(0);
}
}
}

So then where is the error?

You forgot the break; after the cases

Code:java

public void applyDmg(Entity entity, int damage) 
{
    switch (entity.getType().getTypeId())
    {
        case 54:
            mehZomboids yourZombie = (mehZomboids)((CraftEntity) entity).getHandle();
            yourZombie.ondamage(damage);
            if (yourZombie.getRealHealth() <= 0) 
            {
                entity.getWorld().spawnEntity(entity.getLocation(), EntityType.EXPERIENCE_ORB);
                ItemStack i = new ItemStack(Material.BEACON,27);
                entity.getWorld().dropItem(entity.getLocation(),i );
                yourZombie.setHealth(0);
            }
            break; // BRRREEEAAAAAAK
        case 51:
            mehSkeles yourSkele = (mehSkeles)((CraftEntity) entity).getHandle();
            yourSkele.ondamage(damage);
            if (yourSkele.getRealHealth() <= 0) 
            {
                entity.getWorld().spawnEntity(entity.getLocation(), EntityType.EXPERIENCE_ORB);
                ItemStack i = new ItemStack(Material.BEACON,27);
                entity.getWorld().dropItem(entity.getLocation(),i );
                yourSkele.setHealth(0);
            }
            break; // BRRREEEAAAAKKK, not really neccesary as it is the last case
    }
}

 

fireblast709

Code:java

 
package com.gmail.babmush.Adventurer.mobs;
 
import net.minecraft.server.World;
 
public class mehSkeles extends net.minecraft.server.EntitySkeleton{
private int cHealth= 1;
public mehSkeles(World world) {
super(world);
 
}
@Override
public int getMaxHealth()
{
return 10000;
}
public int getRealHealth()
{
return cHealth;
}
public void setRealHealth(int i){
cHealth = i;
}
public void ondamage(int dmg){
cHealth = cHealth -dmg;
}
 
}
 

Ah, also I screwed up skeleton AI i think... they don't carry bows and if you get close melee u but still act like they can shoot you ... Yeah I make alot of mistakes /sigh

 

try this:

Code:java

public mehSkeles(World world) 
{
    super(world);
    this.setEquipment(0, CraftItemStack.createNMSItemStack(new ItemStack(Material.BOW, 1)));
}

 

So just giving them bows lets the shoot? Interesting and thank you for responding to my multiple help threads
