I hope posting my ideas for mods isn't spam, but I want to get ideas out and such I was thinking of making a mod which would add a block that would be placed at the base of a tree. It would then generate power from the tree, for trees generate energy from the sun. I would want the block to generate more power based on the size of the tree. So how would I make the block tell how many wood blocks or such are present in the tree. If I just get pointes in the right direction that would help so much.
