Brilliant explanation! I knew about the problem stemming from entities being registered too high/low and was wondering why the error came up as a nullpointerexception instead of arrayoutofbounds.

Thanks. Last time I checked, ModLoader hasn't fixed the issue but Forge has made progress on it. At the time I made this thread I never used Forge but now I changed my mind because of this. I might do a small NPC and non-living entity tutorial for Forge on here.

dont use getUniqueID , use a number from -128 to 127..... for Example: 121.
When did this become a problem? Should i always use my own numbers when making mods? The tutorial I used reccomended that function(it was causing me an error too) I just want to know why it's causing the error.

Um did you actually read this thread? It explains everything. As for using numbers you can but I also made a method that will correctly get a Unique Id. http://pastebin.com/TSLCaD48 In that class there are is a method called getUniqueEntityId.

Hey guys,
I saw this post and realized that this has been my problem all along. My mod was at a standstill. Thanks! Btw, I tried using this method for the entity register and spawn:
[/spoiler]
public void load()
{
ModLoader.registerEntityID(EntityCustomCow.class, "CustomCow", -127);
ModLoader.addSpawn(EntityCustomCow.class, 15, 3, 10, EnumCreatureType.creature);
}
[spoiler/] too bad spoilers don't work
Apparently, Id -127 is not taken, so if you're planning on only adding only one mob to the game, use that number. I'm not sure if this fix is very reliable, but it kept me from recoding everything and it works (I know because I tested it in-game). Hopefully there will be an eventual fix, but for now I'm gonna use -127.
Thanks for the help
blockhead7777.
Ok, i know now, what the problem is. As other users said, in 1.3.1/1.3.2 , Minecraft spawns Mobs on both client and server in SMP. The Client Mob is only a Model which doesnt move, and the Server Mob is the real instance. So... i tried to look, where my Mod only calls the client side to spawn a mob.
At my GUI it printed true.
At onBlockActivated it also printed true.
So it seems, something is wrong with my GUI.
Here is the important Code:
public boolean onBlockActivated(World par1World, int par2, int par3, int par4, EntityPlayer par5EntityPlayer, int par6, float par7, float par8, float par9)
{
TileEntityRobotCreator obj = (TileEntityRobotCreator)par1World.getBlockTileEntity(par2,par3,par4);
EntityPlayerMP emp = null;
EntityPlayerSP smp = null;
if (par5EntityPlayer instanceof EntityPlayerMP)
{
emp = (EntityPlayerMP)par5EntityPlayer;
ModLoader.serverOpenWindow(emp, new CreatorContainer(emp.inventory, obj),10, obj.xCoord, obj.yCoord, obj.zCoord);
}
else
{
smp = (EntityPlayerSP)par5EntityPlayer;
ModLoader.openGUI(smp, new GuiRobotSlot(smp.inventory,(TileEntityRobotCreator)obj));
}
return true;
}
dont use getUniqueID , use a number from -128 to 127..... for Example: 121.
OMG thank you so much for this (give it an id). i have been having problems spawning my mob for days, and i never thought of doing this thank you! because of you my hermit crabs may live

So you only edited the packet class and that stack trace comes up? I see you have some mods installed, are those yours?
What exactly did you edit? Did you do this? http://www.minecraft.../#entry17289084

So you only edited the packet class and that stack trace comes up? I see you have some mods installed, are those yours?
I did 'do this,' but I don't know how to change that
ModLoader.getUniqueEntityId()
thingy to a number from 0-255
Also, I just changed the packet class to the edited copy you put on pastbin.

EDIT: The mods I have are recipebook, which is risugami's mod. Never makes me crash, doesn't edit entity stuff. The more stuff mods are mine. Have 2 cuz I hit the item limit lol

Anything that extends EntityLiving or implements IAnimals use the following methods.
Use this method for getting an unique Entity Id
Look at that same class for adding spawns as well.
For other non living entities you do the same as above but you have to set the entity tracking.
I haven't tried this out so I don't know if it's %100 correct.
but not now, maybe next day.
thanks for this

My mod was at a standstill. Thanks! Btw, I tried using this method for the entity register and spawn:
[/spoiler]
public void load()
{
ModLoader.registerEntityID(EntityCustomCow.class, "CustomCow", -127);
ModLoader.addSpawn(EntityCustomCow.class, 15, 3, 10, EnumCreatureType.creature);
}
[spoiler/]
too bad spoilers don't workApparently, Id -127 is not taken, so if you're planning on only adding only one mob to the game, use that number. I'm not sure if this fix is very reliable, but it kept me from recoding everything and it works (I know because I tested it in-game). Hopefully there will be an eventual fix, but for now I'm gonna use -127.
Thanks for the help

I will recommend you read this post in the thread. http://www.minecraftforum.net/topic/1417041-mod-entity-problem/page__st__100#entry17786787
It explains why using negative numbers for ids isn't a good idea and has a Class that will help get unique Ids. Or you could switch to Forge,

OMG thank you so much for this (give it an id). i have been having problems spawning my mob for days, and i never thought of doing this thank you! because of you my hermit crabs may live

Did you do this? http://www.minecraft.../#entry17289084
So you only edited the packet class and that stack trace comes up? I see you have some mods installed, are those yours?
I did 'do this,' but I don't know how to change that
thingy to a number from 0-255
Also, I just changed the packet class to the edited copy you put on pastbin.
Double check:

Never makes me crash, doesn't edit entity stuff. The more stuff mods are mine. Have 2 cuz I hit the item limit lol
What? You don't, instead of using that method just input a integer from 0 to 255. Just to make sure ids don't collide you could use this class I made http://pastebin.com/6hkaGeE1 There are methods for getting unique ids. Or use Forge http://www.minecraftforum.net/topic/1417041-mod-entity-problem/page__st__120#entry18153982
The Packet class doesn't have any problems.
