I used to register my entities using the registerGlobalID() method, and it was possible to use the /summon command to properly spawn them.
However, after a lot of discussion with some people I trust to know better I have switched to the registerModEntityID() method, but I can't seem to use the vanilla /summon command for my custom entities.
I was able to create my own command (/conjure) which could basically do the thing for my custom entities. I also could probably figure out how to intercept the /summon command.
But I'm simply wondering if the /summon command can be used as-is with the custom entities. Like maybe I need to reference the entity differently, maybe "modid.entity_name" or something?
I don't mind creating my own commands, but I prefer to hook into vanilla whenever possible.
It seems to me that it has to either do with the interact() method (since technically I'm right-clicking on an entity), in particular in the case where I right-click with a spawn egg in hand.
But in any case, since the discussion also got me thinking about proper way to register entities I'm sort of starting grounds up again with changing the way I register entities (changing to only use modEntityID) and using my own custom spawn eggs. I have both of those working so far.
So didn't really solve the problem, but figure at some point I'll figure it out.
Okay, I'm getting confused between the use of the EntityRegistry.registerGlobalEntityID() and the EntityRegistry.registerModEntity() methods for entity registration because I looked at four tutorials that give conflicting advice:A tutorial here (http://www.minecraftforge.net/wiki/How_to_register_a_mob_entity#Registering_an_Entity) indicates to only use the registerGlobalEntityID(). It says:
Put the following in your mod file's load() method:EntityRegistry.registerGlobalEntityID(MyEntity.class, "MyEntityName", myentityid)[/size]Where MyEntity is the name of your entity's class, "MyEntityName" is the name of the entity, and myentityid will be the number Minecraft uses to identify the mob. You can get a unique, unused entity id by calling EntityRegistry.findGlobalUniqueEntityId() instead of myentityid.
There is only one method for registering and adding tracking.EntityRegistry.registerModEntity(Class entityClass, String entityName, int id, Object mod, int trackingRange, int updateFrequency, boolean sendsVelocityUpdates) : void
You also need to register your entity as a mod entity, using a mod-specific id. I do so using a static int modEntityIndex that I just iterate each time, and a custom helper method that I use for entities that have spawn eggs:public static void registerEntity(Class entityClass, String name, int primaryColor, int secondaryColor) { int id = EntityRegistry.findGlobalUniqueEntityId(); EntityRegistry.registerGlobalEntityID(entityClass, name, id, primaryColor, secondaryColor); EntityRegistry.registerModEntity(entityClass, name, ++modEntityIndex, ZSSMain.instance, 80, 3, false); }
So which way is correct? The weird thing is they all kinda work -- I tried all three and can spawn the entities -- but I assume there is some invisible bad stuff going on if you do it the wrong way.
It basically it is saying that the global id list is limited to 255 and if you read up in the thread you'll see that this is caused by some (byte) casting type behavior in the packets.
It actually says that you should ONLY register using the mod registry (and also manually register your own spawn eggs).
In any case, I have tried all three combinations of -- registering with only globalID, registering with both globalID and modEntityIndex, and also only modEntityIndex (plus manually added spawn egg) -- and ALL of these continue to have the same problem -- exactly the same crash where trying to spawn on top of another causes the crash with warning about skipping entity with ID 0.
I'm beginning to think it is not a registration problem (although now I need to rethink registration to ensure I am doing it properly), but either an issue with interaction with existing entity or an issue with two entities trying to occupy the same space (maybe some sort of collision or obstacle resolution code having trouble?)
You also need to register your entity as a mod entity, using a mod-specific id. I do so using a static int modEntityIndex that I just iterate each time, and a custom helper method that I use for entities that have spawn eggs:
public static void registerEntity(Class entityClass, String name, int primaryColor, int secondaryColor) {
int id = EntityRegistry.findGlobalUniqueEntityId();
EntityRegistry.registerGlobalEntityID(entityClass, name, id, primaryColor, secondaryColor);
EntityRegistry.registerModEntity(entityClass, name, ++modEntityIndex, ZSSMain.instance, 80, 3, false);
}
Hmm, this is example of how I usually get tripped up -- I was following some tutorial that didn't have the registerModEntity and furthermore the mod kinda works without it.
Did you mean for the modEnityIndex to be its own index different than id from global ID? Any reason not to use same id as the global one? Maybe because you want to iterate through them at some point? Anyway, my registration method looks like this now:
But it still has the same message"[Client thread/WARN]: Skipping Entity with id 0 "
Is caused (I'm pretty sure) because you didn't register your entity with the registerModEntity method. That's the method that tells the client side which class of entity to spawn, among other tracking related things.
The weird thing is that the mod worked pretty decently without that registration. I mean the entities appeared, they each behaved as individuals, if you saved a game and reloaded they were still there. So I'm not quite sure what this registry is really doing.
But I still must be doing something wrong with registration. Did my code above implement what you suggested?
On a side note, if you want to clear the AI, you can do so simply by invoking "clear()" on the task list:
tasks.taskEntries.clear();
Same for target tasks.
Thanks yeah. I had originally been being selective with what was removed but then eventually it became a full clear.
Anyway, it is still failing with same symptoms and error message.
I have a custom EntityTiger (basically a wolf that has new texture) and registered with a spawn egg. This works generally, the tiger will spawn naturally and will also spawn with the egg if I just right-click once. However, if I hold down right-click (to spawn multiple entities) the game crashes with the following error:

However, this also occurs if I try to spawn my tiger right on top of another tiger. I have other entities too that are behaving the same, even though they are extended from different classes. Vanilla entities spawn fine (on top of each other, with babies, etc.)
Anyway, here is some of my code that might be relevant.

Probably important note: based on the console message I've got in the code, that the crash happens after the constructor for the spawned entity is called on server side but before it is called on the Client side.

However, after a lot of discussion with some people I trust to know better I have switched to the registerModEntityID() method, but I can't seem to use the vanilla /summon command for my custom entities.
I was able to create my own command (/conjure) which could basically do the thing for my custom entities. I also could probably figure out how to intercept the /summon command.
But I'm simply wondering if the /summon command can be used as-is with the custom entities. Like maybe I need to reference the entity differently, maybe "modid.entity_name" or something?
I don't mind creating my own commands, but I prefer to hook into vanilla whenever possible.
0
But in any case, since the discussion also got me thinking about proper way to register entities I'm sort of starting grounds up again with changing the way I register entities (changing to only use modEntityID) and using my own custom spawn eggs. I have both of those working so far.
So didn't really solve the problem, but figure at some point I'll figure it out.
1
You also need to register your entity as a mod entity, using a mod-specific id. I do so using a static int modEntityIndex that I just iterate each time, and a custom helper method that I use for entities that have spawn eggs:public static void registerEntity(Class entityClass, String name, int primaryColor, int secondaryColor) { int id = EntityRegistry.findGlobalUniqueEntityId(); EntityRegistry.registerGlobalEntityID(entityClass, name, id, primaryColor, secondaryColor); EntityRegistry.registerModEntity(entityClass, name, ++modEntityIndex, ZSSMain.instance, 80, 3, false); }So which way is correct? The weird thing is they all kinda work -- I tried all three and can spawn the entities -- but I assume there is some invisible bad stuff going on if you do it the wrong way.0
It basically it is saying that the global id list is limited to 255 and if you read up in the thread you'll see that this is caused by some (byte) casting type behavior in the packets.
It actually says that you should ONLY register using the mod registry (and also manually register your own spawn eggs).
In any case, I have tried all three combinations of -- registering with only globalID, registering with both globalID and modEntityIndex, and also only modEntityIndex (plus manually added spawn egg) -- and ALL of these continue to have the same problem -- exactly the same crash where trying to spawn on top of another causes the crash with warning about skipping entity with ID 0.
I'm beginning to think it is not a registration problem (although now I need to rethink registration to ensure I am doing it properly), but either an issue with interaction with existing entity or an issue with two entities trying to occupy the same space (maybe some sort of collision or obstacle resolution code having trouble?)
0
Hmm, this is example of how I usually get tripped up -- I was following some tutorial that didn't have the registerModEntity and furthermore the mod kinda works without it.
Did you mean for the modEnityIndex to be its own index different than id from global ID? Any reason not to use same id as the global one? Maybe because you want to iterate through them at some point? Anyway, my registration method looks like this now:
public void registerEntities() { modEntityIndex = -1 ; // since increment on first use to start at zero // Big cats EntityRegistry.registerGlobalEntityID(EntityTiger.class, "tiger", EntityRegistry.findGlobalUniqueEntityId(), 0xFF9933, 0x000000); EntityRegistry.registerModEntity(EntityTiger.class, "tiger", ++modEntityIndex, WildAnimals.instance, 80, 3, false); EntityRegistry.registerGlobalEntityID(EntityManEatingTiger.class, "maneatingtiger", EntityRegistry.findGlobalUniqueEntityId()); EntityRegistry.registerModEntity(EntityManEatingTiger.class, "maneatingtiger", ++modEntityIndex, WildAnimals.instance, 80, 3, false); EntityRegistry.registerGlobalEntityID(EntityLion.class, "lion", EntityRegistry.findGlobalUniqueEntityId(), 0xE3D8B6, 0x000000); EntityRegistry.registerModEntity(EntityLion.class, "lion", ++modEntityIndex, WildAnimals.instance, 80, 3, false); EntityRegistry.registerGlobalEntityID(EntityLynx.class, "lynx", EntityRegistry.findGlobalUniqueEntityId(), 0xE3D8B6, 0xFFFFFF); EntityRegistry.registerModEntity(EntityLynx.class, "lynx", ++modEntityIndex, WildAnimals.instance, 80, 3, false); EntityRegistry.registerGlobalEntityID(EntityJaguar.class, "jaguar", EntityRegistry.findGlobalUniqueEntityId(), 0x000000, 0x000000); EntityRegistry.registerModEntity(EntityJaguar.class, "jaguar", ++modEntityIndex, WildAnimals.instance, 80, 3, false); // Herd animals EntityRegistry.registerGlobalEntityID(EntityElephant.class, "elephant", EntityRegistry.findGlobalUniqueEntityId(), 0xBDBDBD, 0xD1D1D1); EntityRegistry.registerModEntity(EntityElephant.class, "elephant", ++modEntityIndex, WildAnimals.instance, 80, 3, false); }But it still has the same message"[Client thread/WARN]: Skipping Entity with id 0 "
The weird thing is that the mod worked pretty decently without that registration. I mean the entities appeared, they each behaved as individuals, if you saved a game and reloaded they were still there. So I'm not quite sure what this registry is really doing.
But I still must be doing something wrong with registration. Did my code above implement what you suggested?
Thanks yeah. I had originally been being selective with what was removed but then eventually it became a full clear.
Anyway, it is still failing with same symptoms and error message.

I have a custom EntityTiger (basically a wolf that has new texture) and registered with a spawn egg. This works generally, the tiger will spawn naturally and will also spawn with the egg if I just right-click once. However, if I hold down right-click (to spawn multiple entities) the game crashes with the following error:
However, this also occurs if I try to spawn my tiger right on top of another tiger. I have other entities too that are behaving the same, even though they are extended from different classes. Vanilla entities spawn fine (on top of each other, with babies, etc.)
Anyway, here is some of my code that might be relevant.
