Retain item NBT on place.

I am trying to figure out how i can retain some custom NBT strings given to an item (a TnT block), so that way the TnT block has those tags... i was thinking of transferring them on the 'player interact' event, but I'm not sure if there is a better way of doing it.

Basically what im trying to do is, add a custom TnT block, that does some custom stuff when it explodes...
(I'm not a noob /i hope XD/, so be free to be as technical as you'd like :slight_smile: )

 

You would probably need to place a custom tile when the tnt is placed and set the nbt tags to the tile, then when it is ignited it checks for the tile at its position and gets the nbt tags to set to the entity

 

You can create a tile easily with this virion

Thanks for the suggestions, using block entities seems like the best solution for this, currently. Thanks!
