Help: BlockNamehereLeaves

1. READ THE BLOCK TUTORIAL FIRST!

1.5. For the ID dropped part, change the 3 to how rare you want your block/item to drop from leaves. Leave the rest of that Id dropped part.

2. At the public void updateblabla, fill in all the Namehere's.

3. Leave the rest of this file.

Help: BlockNamehereWood

1. Just change names that need to be changed.

2. Ignore all the other stuff.

Help: mod_NamehereTree

1. If you've read the block tutorial, then you will know just about all of this.

2. At the public generate surfacce whatever bit, where it has the int's and the (16)'s
mess around with this to change how it generates, I'm not too sure just yet.

Help: WorldGenNamehereTrees

1. All you have to do for this is change the Namehere's and so on.

2. More experienced modders can mess with it to try something different.

Done! Don't expect it to be easy though... I really don't want to explain everything for a long time. There will be a few errors no doubt. Anyway, good luck.

New Dimension

Note: You will need a thing called fernflower.jar for this to work. You can get it here. Put it in runtime/bin along with the other .jar's. Then put ShockahPI in your normal jar where you put modloader and decompile.
