How to detect how many blocks above player

Hey I'm trying to create a suffication mod and I was wondering how to detect how many blocks are above the player. For example if the player has 3 or more blocks above him his exp level starts to drop and eventually starts taking damage....


Also I was wondering of there are any thirst mods or if you can tell me how to create one...

Thanks in advance...

 

Mod or Plugin?

 

Plugin? This is plugin development after all...

You can get the players location, and then make a for loop that checks every block above the player. If the block is not Air, then it is solid.

 

I would do as stated above, except I would personally use a BlockIterator over a loop. You know the world height (256 isn't it... Shrugs), so I would do the following: (note: this was written in notepad and likely contains typos)

Code:

    public Integer GetSolidBlocksAbove()
    {
        Player player = YOURPLAYERSOURCE;
        World world = player.getWorld();
        Location location = player.getLocation();
        int distance = 256 - loc.getBlockY();
        int SolidAboveCount = 0;
 
        BlockIterator bi = new BlockIterator( world, location.toVector(), new Vector( 0, 1, 0 ), 0, distance );
        while( bi.hasNext() )
        {
            Block toinspect = bi.next();
            if( toinspect.getType() != Material.AIR )
                SolidAboveCount++;
        }
        return SolidAboveCount;
    }

This will take the players location, look straight up and shoot a 'ray' the exact amount of blocks from where you stand to the maps max height, then it takes every block the 'ray' passes through and evaluates them in a loop, if any of those blocks aren't air it counts it. Once the loop and counting is done the function returns the total count of solid blocks above the player.

I hope this makes sense and helps, good luck with your project!
