[1.7.10] 'API' that registers your block and item

DonKresenko · November 4, 2014

I'm making a mod. I wanted to make the code look nicer and make it easier. I tried to make like and API that will register my block and item and the crafting recipe. Here's an example:

Methods in the API class:

public static void createPair(Block pairBlock, Item pairItem, Item pairSubItem, String pairName) {	
	pairBlock = new PairBlock().setHardness(0.5F).setStepSound(Block.soundTypeCloth).setBlockName(pairName).setBlockTextureName(pairName);
	pairItem = new PairItem(pairBlock).setMaxStackSize(1).setUnlocalizedName(pairName).setTextureName(pairName); 

	registerBlock(pairBlock, pairName);
	registerItem(pairItem, pairName);

	GameRegistry.addRecipe(new ItemStack(pairItem), new Object[]{"B", "S", "B", 'B', pairBlock, 'S', pairSubItem});
}
private static void registerBlock(Block block, String name) {
	GameRegistry.registerBlock(block, block.getUnlocalizedName());
	LanguageRegistry.addName(block, name);
}

private static void registerItem(Item item, String name) {
	GameRegistry.registerItem(item, item.getUnlocalizedName());
	LanguageRegistry.addName(item, name);
}

And this is in my main class:

PairAPI.createPair(PairBlockTest, PairItemTest, ItemSubTest, "pair");

But Minecraft just keep crashing. Where am I making a mistake?

It's pointing me to the line in the main class

I also noticed that when you use addRecipe, you do "B", instead of " B ".. spaces matter, as there should be 3 chars.. space = no item in the crafting recipe.

By the way.. you should post the crash log and the main class.. we aren't wizards
