So in my process of making a mod similar to magical crops, but with melons, I have ran into the problem of not being able to understand how to implement the melons themselves. I have both the Melon Block and Item created, but I cannot make sense of the vanilla code on how to make them grow using the BlockStem class. Can anyone point me in the direction of a tutorial on how to make these grow, or help me understand it a little better?

You need two blocks and a seed.  One block is the crop (the stem) and the other is the melon.  When the stem is fully grown (and not attached to a melon) and it grows, it picks a random side that is clear and places the melon there.

So from what I understand I need a BlockMelonStem type class and a BlockMelon class for each melon, and have that choose a side when it is fully grown?

Pretty much.

The problem that I am running into is that I cannot extend the BlockStem class, nor use it to declare new Stems in my Items Class. In this case I would have to write a new class basically copying the vanilla version. Right?

public class BlockTestStem extends BlockStem {

public BlockTestStem(Block crop) {
	super(crop);
}
}

 

Worked for me, what's the problem?

Not sure what It was. tried it again and it worked. thanks for the help! This should let me progress a little more
