[1.12] How to activate a block with an item

[IlTosaerba]

Hello modders

 

For my mod I have a block which can power.

 

I need that the block power only when i click on it with a particular item...

 

For example

Block : Card reader

Item : Personal card

 

When I click with the personal card on the card reader, after a while the card reader power the Office Printer .

If i click on the card reader with any other Item it will do nothing

Override Block::onBlockActivated in your Card Reader Block class, and check if playerIn.getHeldItemMainHand().getItem() is an instance of ItemPersonalCard, and do what you want.
