Solved how to check blocks around player

Hi! i was wondering how i can check blocks around player. Like this photo...

I just asking how can i . i dont want the code . Thanks for helping...

 

You can do this by using a for loop. If you want to check only the x and z direction use 2 for loops. Start at one corner and keep adding the x and z coördinate to that corner location (location.add()

 

Simply get the player's location and then:

• Add 3 to its X-coordinate
• or subtract 3 from its X-coordinate
• or add 3 to its Z-coordinate
• or subtract 3 from its Z-coordinate

You can use:

Code:java

loc.add(x, y, z);

Or:

Code:java

loc.subtract(x, y, z);

These methods return locations whose co-ordinates are greater then or lesser than the co-ordinates of loc by the amount specified.

EDIT: Much easier than the methods specified above this post.

It's indeed possible to use that way, but it could get pretty messy when you're going to check a lot of blocks. Using a for loop you'll keep it more clear.

 

You could first get the block of the player:

Code:

Block pBlock = player.getLocation().getBlock();

Then you could use the getRelative() method to get the ones to the right, left, infront, behind.

Code:

Block northBlock = pBlock.getRelative(BlockFace.NORTH);
Block southBlock = pBlock.getRelative(BlockFace.SOUTH);
Block westBlock = pBlock.getRelative(BlockFace.WEST);
Block eastBlock = pBlock.getRelative(BlockFace.EAST);

If you want to add spacings (e.g. 1 block gap), you could have a for loop.

Code:

Block northBlock = pBlock.getRelative(BlockFace.NORTH);
Block southBlock = pBlock.getRelative(BlockFace.SOUTH);
Block westBlock = pBlock.getRelative(BlockFace.WEST);
Block eastBlock = pBlock.getRelative(BlockFace.EAST);
int spacing = 1;
for (int i = 0; i < spacing; i++) {
    northBlock = northBlock.getRelative(BlockFace.NORTH);
    southBlock = southBlock.getRelative(BlockFace.SOUTH);
    westBlock = westBlock.getRelative(BlockFace.WEST);
    eastBlock = eastBlock.getRelative(BlockFace.EAST);
}

Or... you could just add <gap> to pBlock.getLocation() each time, add then use .getBlock().getRelative().

 

xmarinusx In the OP he only asked how to check those 4 blocks though. Utilising for-loops would be excessive in my opinion and would disguise what blocks you actually want to obtain... But yes you're correct, if he wants to check all blocks between two points in 3-D space, he shouldn't definitely use a loop to iterate over them.

 

He wants the blocks that are further away, using a for loop would be easier then in my opinion.

 

Er, no, it wont.
Its like saying that using a loop to do 5 times add 1 to an int is simpler than int + 5.
Using location.add works fine here.

 

True, but look at the bottom of my code.

"Hi! i was wondering how i can check blocks around player. Like this photo..." is probably what confused me
If only those 4 blocks need to be checked I wouldn't use a for loop indeed

 

Thanks for all reply

blocks can be more not just 4
---------------------------
yeah i will use for loop but i dont know which methods i have to use .i tried this but isnt work...

Code:java

 
...
if( player.getLocation().getBlock().getRelative(BlockFace.NORTH).getMaterial == Material.LAPIS_BLOCK )
{
   //codes
}
...
 

 

Replace '.getMaterial' with '.getType()' and it should work.

 

Code:java

@EventHandler
public void onPlayerRitual(PlayerDropItemEvent event)
{
Player player = event.getPlayer();
Location loc = player.getLocation();
 
loc = loc.add(3, 0, 3);
player.sendMessage("Drop event work");//For debug
for(int i=0; i < 7 ; i++)
{
for(int j =0; j < 7 ; j++ )
if( loc.getBlock().getType() == Material.LAPIS_BLOCK )
{
player.sendMessage("for loop work");//For debug
 
loc = loc.add(0,0,1); // Just debug for z coordinate
}
}
}

Where is wrong ? its not say "for loop work". And not work. This is litte testing code. If this work i will write other pieces

xmarinusx Thanks for getTytpe() KingFaris11 Traks

 

crzytlp Does it say "Drop event work"? Mabe it doesn't say "for loop work" because there is no LAPIS_BLOCK. And I would compare materials with .equals();

 

stonar96 Comparing enum works fine with ==, as well as being null safe.

 

Necrodoom ok, I said I would. But you are right

 

Yes you are right ) its need be wool and some changes in code İts perfect now

Code:java

@EventHandler
    public void onPlayerRitual(PlayerDropItemEvent event)
    {
        Player player = event.getPlayer();
        Location loc = player.getLocation();
        int temp = 0;
 
        loc = loc.add(3, 0, 3);
        player.sendMessage("Drop event work");//For debug
        player.sendMessage(loc.getX() + " " + loc.getZ());
 
        for(int i=0; i < 7 ; i++)
        {
            for(int j =0; j < 7 ; j++ )
            {
                if( loc.getBlock().getType() == Material.WOOL )
                {
                    player.sendMessage(i + " " + j);//For debug
                    temp++;
                }
 
                loc = loc.add(0,0,-1);
            }
 
            loc = loc.add(-1,0,7);
        }
 
        player.sendMessage("Blocks :" + temp);//For debug
        temp = 0;
    }
