[1.6.4]Custom Sapling Help?

[RetsuWolf]

Greetings! I've been working on a mod recently and I want to create a sapling for my tree that will grow when bonemealed. Anyone know any good tutorials for this? I've been been looking around in source code for this though I haven't been able to find anything. Any help is greatly appreciated! Also if anyone knows how to make a certain tree generate on only certain blocks that would be excellent if you could inform me! Thank you!

Use the BonemealEvent.

In there check if the event's block is your sapling, check if the world.isRemote == false and then call your sapling grow method (I called it markOrGrowMarked) and also set the result of the event to Result.ALLOW

 

In 1.7, you could also implement IGrowable in your block, but note that the method names aren't readable yet!
