array of blocks within a radius

How would I get an array of blocks within a radius of another block? I tried to figure it out but couldn't find anything =/

can anyone help with this?

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Some pseudo code:

Code:

// world, centerX,centerY, centerZ are variables.
List<Block> blocks = ArrayList;
int radius = 5;
for (int x = -centerX; x < centerX; x++)
for (int y = -centerY; x < centerY; y++)
for (int z = -centerZ; x < centerZ; z++)
block.add(world.getBlockAt(x,y,z)

Hope that helps.

I thought I got it and tried this

Code:

List<Block> blocks = new ArrayList<Block>();
            int radius = getConfig().getInt("Protection_Radius");
            for (int x = term.getX() - radius; x < term.getX(); x++)
            {
                for (int y = term.getY() - radius; y < term.getY(); y++)
                {
                    for (int z = term.getZ() - radius; z < term.getZ(); z++)
                    {
                        blocks.add(term.getWorld().getBlockAt(x,y,z));
                    }
                }
            }

and it didn't work.
What am I doing wrong?

 

....... < term.get...() + radius

 

oh my bad. Thank you it worked!
