Hello guys,

 

I would suggest to implement a hook which fires an event once a player placed a block.

It should give you information about where and which block was placed (and maybe which player did place the block).

 

It would be very helpful. I'm currently searching for a solution, because I need to find all blocks of type X in range of 50 blocks (each axis).

If I run through all blocks (this every 5 seconds) as I now do this will cause probably some lags and is a really un-performant solution.

 

If my block would have been noticed everytime this block X was placed, it would save massive resources for searching those blocks.

The calculation of how far this block is away is no problem at all.

 

 

So please implement this hook (if it's not already in and I just found nothing in the docs...)

Blocks are told when THEY are placed, but a generic BlockPlaced is hard to do, there are hundreds of avenues that could 'place' a block.

We have the PlayerInteractEvent as diesieben mentioned as a typically 'this player is using smething' event.

It sounds for your example that what you want done can be done fairly easily.

Basiclaly.. you want a block, when placed, to flood out and place other blocks?

Ya thats simple to do in the mechanics we have in place.

Okay... I tried it this way. The only problem is: I have to place the block AND then click on it.

Only after this step my block gets connected.

 

Is there a solution to do this without having to click the block? So the event fires (for this block, not for the one on which top you built the block) instantly when placing?

There is a 'ive been placed' function in Block itself.

You can also make a custom item that fires the notifcation to itself.

There are many ways you can go around this... Nothing need be done on our end for your situation.

There are in fact, two functions.

 

onBlockAddedToWorld

and

onBlockPlacedBy

 

If I am remembering the full names correctly.  The first one will fire any time any block "becomes" your block (pushed by a piston, placed by endermen, added in worldgen, etc) the other is only when the player directly places it from their inventory (and which player is passed).

How would one go about doing this if they're using it to restrict blocks added from other mods? Lets say I have custom dimension A and I don't want block B to ever be placed there. Is there a way I can prevent block B from being placed in dimension A? block B would be from another mod.

Maybe SetBlockEvent? That called from World.setBlock(x, y, z, block, meta, flag)?

I really need that kind of detection.

What if it was only called when the player placed a block?
