What is the difference between EntityRegistry.registerModEntity and EntityRegistry.registerGlobalEntityID and when to use the one or the other?

registerModEntity is required for MP tracking stuff, so the entity works on a dedicated server with multiple clients connected to it, I believe. registerGlobalEntityID is the base method for registering entities and should always be used in order to make entities work.

 

I would suggest to use both methods. The registerGlobalEntityID first, then registerModEntity.

I had done it the wrong way around then. First registerModEntity, then registerGlobalEntityID. As a result, the spawn egg's did not show and I had a warning in the ForgeModLoader client log

 

 

2012-09-24 11:42:51 [FINEST] [ForgeModLoader] Automatically registered mod ChocoCraft entity ChocoboYellow as ChocoCraft.ChocoboYellow

2012-09-24 11:42:51 [WARNING] [ForgeModLoader] The mod ChocoCraft tried to register the entity class class chococraft.common.entities.colours.EntityChocoboYellow which was already registered - if you wish to override default naming for FML mod entities, register it here first

 

 

Thus I presume if omited, EntityRegistry.registerModEntity will be called by the EntityRegistry.registerGlobalEntityID, since right now I'm doing exactly that and I have the respective spawnEggs and can spawn my entities.

 

But if the explicit call of both methods in the correct order are the correct way, I'll of course do it like that, first the EntityRegistry.registerGlobalEntityID, then the EntityRegistry.registerModEntity.

Well, I can ensure you that neither the registerGlobalEntityID nor the registerModEntity methods call eachother.

 

There are two versions of registerGlobalEntityID, one with two additional parameters - the foreground and background color for the egg -, which will add an egg, and one without these parameters, which won't add an egg.

 

Anyway you HAVE to call these methods in this order or else you will get the error you mentioned.

I have now tried the version with registerGlobalEntityID first and registerModEntity second and I'm receiving again a warning about double registration. So using both might not be the correct way to do things

 

So I'll keep the registerGlobalEntityID and remove the registerModEntity (I would like to use the eggs for testing).

 

The registerModEntity as a few other parameters trackingRange, updateFrequency and a boolean called sendsVelocityUpdates. Which I can not set when using the other register method. Could it be: one is for registering the entity in the client side methods (with the eggs) and one for the server side methods (with the updateFrequency etc...) <- wild guessing here

 

That's weird that you get the error even with the right order. It works for me. Could you provide the code where you register your entities?

 

    
@Init
public void loadChocoCraft(FMLInitializationEvent loadEvent)
{
   this.createItemInstances();
    	
   this.createBlockInstances();

   GameRegistry.registerWorldGenerator(new WorldGenGysahls());
        
   proxy.registerRenderThings();
}


private void registerChocobos()

   int globUniEntIdChicobo = EntityRegistry.findGlobalUniqueEntityId();
   String entNameChicobo = "Chicobo";
   LanguageRegistry.instance().addStringLocalization("entity.Chicobo.name", "en_US", "Chicobo");
   EntityRegistry.registerGlobalEntityID(EntityChicobo.class, entNameChicobo, globUniEntIdChicobo, eggColChicobo, eggDotsColChicobo);
   EntityRegistry.registerModEntity(EntityChicobo.class, entNameChicobo, chicoboEntityId, instance, 10, 10, true);

   // Yellow
   int eggColYellow = (253 << 16) + (206 <<  + 125;
   int eggDotsColYellow = (178 << 16) + (147 <<  + 85;
   int globUniEntIdYellow = EntityRegistry.findGlobalUniqueEntityId();
   String entNameYellow = "ChocoboYellow";
   LanguageRegistry.instance().addStringLocalization("entity.ChocoboYellow.name", "en_US", "Yellow Chocobo");
   EntityRegistry.registerGlobalEntityID(EntityChocoboYellow.class, entNameYellow, globUniEntIdYellow, eggColYellow, eggDotsColYellow);
   EntityRegistry.registerModEntity(EntityChocoboYellow.class, entNameYellow, chocoboYellowEntityId, instance, 10, 10, true);

   // the block above for 9 different entities
        
}

looks like Millenaire has similar effects ... (I'm running some other mods too, to see if I'll have no compatibility problems ...
