Searching right event to suscribe to.

Hi there,

We're currently using the following event to handle our actions:

 

    @SubscribeEvent
    public void onPlayerInteract(@NotNull final PlayerInteractEvent.RightClickBlock event)
    {

 

What we want is, if a player places one of our blocks certain actions should be executed.

But, unfortunately, this event also gets called when the player right clicks a bed with the block or an itemRack or similar.

The block doesn't get placed but the event does get executed. Is there a way around this?

 

Thanks

You need to use if-checks to check to see if the block placed is one of your blocks.  If it's not, do nothing, if it is, run the code.

 

-or-

 

You could write a custom ItemBlock class.  Which is more better.  You control your own blocks, you can write code that only occurs within your own blocks by writing the code IN your OWN blocks.

I'm checking if it is my own block, but the problem is that sometimes when executing this action the block does not get placed (like when you rightclick a bed with your block in the hand)

 

I need to be able to cancel the event and be able to detect if it really has been placed.

o..O

What on earth are you trying to accomplish?

[Raycoms]

We are implementing minecolonies.

 

A colony gets created around the center of the "TownHallBlock" you placed, when you place it the first time.

The workerHuts (Lumberjack,miner etc) also get created at the place you first placed their "Hutblock".

 

Now when I have the townhall in my hand and rightclick the bed, the colony gets created but the chest not placed.

 

I only want to create the colony when I'm totally sure the chest has been placed.

[Draco18s]

Why are you not performing this creation effect in the Block's

onBlockPlaced

method?

[Raycoms]

Can I cancel the event there?

[Draco18s]

You don't cancel events inside the method, there's no event there.

 

That method only runs when the block is added to the world.  It will not fire if the player sleeps in a bed.

[Raycoms]

Yeah but I need to be able to cancel the event if the player tries to found a colony at a location he is not supposed to be, like in another colony, or too close to another colony.

[Draco18s]

Do that in the onBlockPlaced method.  If the placement is invalid, drop the block as an item and set the space to air.

[Raycoms]

I think I found an alternative.

 

I will analyze if the placement is valid in the event and will analyze if I can create the colony in the onBlockPlacement.

 

 

Thanks anyway for the effort.

Or you can use the

Block#canPlaceBlockAt()

method to check if the

Block

is placeable at that location.
