I created a Boar mob and tried to make a Monster Spawner via command that spawns my mob.

First I tried with /give @p mob_spawner 1 0 {BlockEntityTag:{EntityId:Skeleton}}. It gave me the basic spawner block which spawns

pigs.

After that I used /setblock ~ ~ ~ mob_spawner 0 destroy {EntityId:Boar}. It spawned the block with the little spinning boar with it,

but spawned nothing.

 

Is the problem in the code or I search somewhere else?

Just to be sure here is my Boar.class

}

}

 

In the main mod class I simply call the handler class above:

EntityHandler.registerMonsters(EntityBoar.class, "Boar");

Can u give me a good tutorial on how to avoid global entity IDs (i know that global IDs can only store 256 entities)?I mean that I wish to use custom IDs and if I'm not mistaken, spawn eggs don't work with custom IDs.
