I've googled it, searched the forums here, searched the minecraft forums, and anything I could imagine but there seems to be no info on how to select Birch, Acacia, Dark Oak, etc woods for code.
For example if (event.world.getBlock(X, Y, Z) == Blocks.log), Blocks.log will always assume it's Oak, and there is no way of choosing any of the other ones, that I know of. I spent 8 months trying to make an event handler and I finally did it. This however is beyond me. Without any documentation Im solely dependent on finding random code by chance that actually does what I'm trying to do. Please help me.
