[1.16.4] Put Spawner Block with EntityType in custom creative Tab

[Heltrato]

Hello, just want to ask for advice how can i have a simpler way to approach this,

1. I want to add a spawner blocks with custom entities on it in the custom creative tab i am making, to make it also available for trade or craft. 

Is there a simpler way to approach this or if you guys have an example i can have a reference or guide too?

 

Thanks a lot.

You need a custom item, because while the vanilla spawner item does have a way to specify the spawned mob (via the BlockEntityTag NBT tag), but only OPs can place such an item.

So you need your own BlockItem class and override onBlockPlaced. In there set the entity type of the placed spawner.

Thanks for the fast response diesieben07, just want to clarify thou, what specific Item/BlockItem class should extend for the spawner block, i cant seem to find any spawner block item related in the minecraft packages atm.
