Ok, here's my problem. Sorry if it's a noobish question.

 

Let's say i'd like to have a creative block that can only be placed  once then no more on ALL SERVER. The block should be UNIQUE!

How can i keep track ( and save the information ) that the block already exists and cannot be placed anymore?

How can i refer to that block in other parts of the code when i need it?

 

Any pointer will be good enough.

Thank you.

Hi

 

Look into Block.onBlockAdded, Block.canPlaceBlockAt, and Block.onBlockPreDestroy.  If you use these to keep track of whether your block is placed or not, you can stop block placement if one already exists.  You will need to store the block count somewhere permanent, i.e. so it gets saved every time the world is saved.  You could look into world.perWorldStorage for that.

Ok, i did it.

One last thing, do i need any more code to make it work well on multiplayer too? is WorldSavedData handled ServerSide ?

 

For others who have the same problem, i advise you to look at these other topics too.

      LOST ASSET RECOVERY SERVICES, CONSIDER USING WIZARD WEB RECOVERY

      By Lawrence Norman · Posted

      It all began with a chance encounter with a testimonial shared by Olivia, a fellow traveler on the winding road of cryptocurrency. Her words spoke of a miraculous recovery orchestrated by Wizard Web Recovery, a beacon of hope in the murky waters of online fraud. Intrigued by her story, I reached out to Wizard Web Recovery, hoping they could work their magic on my blocked crypto recovery. With bated breath, I shared my plight, providing evidence of my dilemma and praying for a solution. To my astonishment, a prompt response came, swift and reassuring. Wizard Web Recovery wasted no time in assessing my situation, guiding me through the process with patience and expertise. and then like a ray of sunshine breaking through the clouds, came the news I had longed for – a new private key had been generated, restoring my precious bitcoins. It was a moment of jubilation, a triumph over adversity that filled me with newfound hope. At that moment, I realized the true power of Wizard Web Recovery, not just as skilled technicians, but as guardians of trust in the digital realm. With their assistance, I reclaimed what was rightfully mine, turning despair into determination and paving the way for a brighter future. But their capabilities did not end there. Delving deeper into their expertise, I discovered that Wizard Web Recovery possessed a wealth of knowledge in reclaiming lost stolen cryptocurrency, and even exposing fraudulent investment schemes. So to all those who find themselves entangled in the web of online fraud, take heart. With the guidance of Wizard Web Recovery, there is a path to redemption.     Write Mail; ( Wizard webrecovery AT  vprogrammer. net )

      How can I add drops when killing an entity? Now there are no drops. How can I add an @override to change the attack speed to 1.6 and show "when in main hand...attack damage,...attack speed"? also, how can I make the item enchantable?

      You shouldn't be extracting the mod .jar, just place it in your mods folder.
