As this is my first mod , i just wanted to change some drops and other stuff , and  i am very interested in leaves because of their decay drops , but i'm not sure on how to do that .

Can someone please help me ?

 

                                                                        Thanks in advance , Disco.

There are to ways to add Drops.. First way. Touch the leaves.class

Second way: You replace the leaves class with your class and ad the drops (better way because when you deinstall the mod the world does not break:

 

here the code for replacing the blocks:

 

  Block.blocksList[17] = null;

  // Block.blocksList  is where all blocks are

  // [17] is the blockID

  // null is to delete the Wood.class

 

  now the replacinh

 

  Block.blocksList[17] = new BlockCustomWood(17).setBlockName("blockWood");

 

  but you must give him an id thats why the (17)

 

i hope it helps
