Checking blocks

[MeskenasBoii]

How can I check for a specific blocks to be check upon so that the event could occur?

From the top of my head;
if (block.getType() == Material.<BLOCK>) {
//do stuff
}

You of course have to know the coordinates of the block you want to check. If you have a Location instance you can call getBlock() on it which returns a value from the Materail enum, so you can then compare it in an if statement, which will return true if a block with the specified type is present at your location.

First message. I had to sorry.

Oh right, but how do I check for the number of blocks in the specified radius?

Use a for loop. Here's one in my ability that I made, hope it helps.

You can iterate over a Collection using a loop (for or while). In your case you could use both.
For loop approach:

int counter = 0;
for (Block block : yourListWithBlocks) {
    // this code runs for all elements in the list
    if (block.getType() == SomeMaterial) {
        counter++;
    }
}

This loop checks how many blocks in the list have the material 'SomeMaterial' and returns that number in the variable 'counter'.

While loop approach: (Disclaimer: I don't work with Iterators much, this could be wrong)

Iterator<Block> iterator = yourListWithBlocks.iterator(); // get the list's iterator
while (iterator.hasNext()) { // while there is a next entry in the iterator
    Block block = iterator.next(); // move to the next element
    if (block.getType() != SomeMaterial) {
        it.remove(); // if the block's type is not equal to 'SomeMaterial', remove it
    }
}

This method will remove all blocks that don't have 'SomeMaterial' as their type from the list.

Thx. I'll try that
