Solved Getting an entire tree

I have an iron golem go to random trees and hit them, but how do I get all the blocks in the tree so I can make them fall?

 

Keep adding and subtracting 1 to the y axis and get all the blocks that are logs?

 

Not all trees are entirely one column.

I think jungle trees can even have wood blocks that are not even touching (even edges/corners) any other wood blocks. Not sure.

Make a HashSet of blocks. Populate it initially with the block that the golem hits. Loop through all the blocks nearby it, and check if they are wood blocks (of the same type as the original wood, the lowest bits of the data tell you what type of tree it is). Add them to the HashSet if they are. Then loop through blocks nearby the new block. You can use recursion or iteration to do this.

 

You need to use recursive methods - the methods that call themselves.

Look at my getTree(anchor, logs, leaves) method.
