I am thinking about modding again after a few weeks or so of being swamped with school. What I want to do is get all the blocks within a radius around the player to test each block for different properties. Is there an easy way of doing this?

To my knowledge, you will have to do it yourself. BlockPos has a method (BlockPos#getAllInBox) to retrieve all the BlockPos within a rectangular prism, but not a sphere. In general, I would pull all the blocks with a cube with the player at the center and using your radius as half the side length. You can then filter out the unwanted blocks with a simple distance check (BlockPos#distanceSq).

 

If you want to only get blocks with a certain properties, it might be a good call to use Google's Iterators#filter with the iterator returned from BlockPos and a custom predicate, which would filter for the distance as well as the block properties you want.

Well, I guess I should have been more clear. A cube around the player will work. Thanks for your help. I think BlockPos::getAllInBox is exactly what I want.
