Tree-Growing Blocks in Minecraft
Learn how to use the Block.onBlockAdded() method in Minecraft to create blocks that grow different types of trees like cube, cylinder, cone, and sphere. Follow step-by-step instructions and work out the math and algorithms on paper first for a smoother coding experience.

TEALS MINECRAFT PROJECT Lecture 5: Block.onBlockAdded()
MINECRAFT COORDINATES Recall the Following Minecraft blocks all have a unique location x, y, and z. X and Z are parallel to the horizon, and Y is up. To place a block at an arbitrary location, use this: world.setBlock(x,y,z, blockType);
Block.onBlockAdded We'll be using (overriding) a new Block method today: public void onBlockAdded (World world, int locX, int locY, int locZ) The Block.onBlockAdded() method is called when a new block is added to the world, at the given location. In lab 4, we used a crystal-growing block to be the seed for a block, and a crystal-growing item to trigger the placement of more blocks to grow the crystal. For lab 5, we'll use the Block.onBlockAdded()method to build a tree from a block as soon as it is placed in the world.
LAB 5: TREE-GROWING BLOCKS For today's lab, we'll be creating four different kinds of blocks, that grow four different types of trees: cube, cylinder, cone, and sphere (in increasing difficulty). A BIG WORD OF ADVICE: work out the math & algorithm on paper first before diving into the code! If you have a clear idea on paper, the coding will be much easier. Everything else you need to know is in the lab write-up.
