gettingRecipeList

[Gnomorian]

Hi, essentualy making a clone of Crafting Bench 2/3 as they both seem dead.

im having trouble with checking if the player has the right items in their inventory or not.

i have a function that runs during postinit to get the list of reciepes from CraftingManager and sort them into 2 lists, ShapedRecipe and ShapelessRecipe

 

public class GGURecipeManager 
{
/**
 * list of all shaped recipes found in the CraftingManager's Recipe List.
 */
private static List<ShapedRecipes> shapedRecipes = new ArrayList<ShapedRecipes>();
/**
 * list of all shapeless recipes found in the CraftingManager's Recipe List.
 */
private static List<ShapelessRecipes> shapelessRecipes = new ArrayList<ShapelessRecipes>();

/**
 * gets the list of recipes from the crafting manager and sorts them into multiple lists to 
 * reduse lookup time during the game.
 * @param recipeList list of recipes from CraftingManager
 */
public static void init(List recipeList) 
{
	for(int i = 0; i<recipeList.size();i++)
	{
		if(recipeList.get(i) instanceof ShapedRecipes) 
		{
			//if(((ShapedRecipes)recipeList.get(i)).getRecipeOutput() != null)
				shapedRecipes.add(((ShapedRecipes)recipeList.get(i)));
		}
		else if(recipeList.get(i) instanceof ShapelessRecipes) 
		{
			if(((ShapelessRecipes)recipeList.get(i)).getRecipeOutput() != null)
				shapelessRecipes.add(((ShapelessRecipes)recipeList.get(i)));
		}
	}
}
/**
 * returns the list of shaped recipes.
 */
public static List<ShapedRecipes> getShaped() 
{
	return shapedRecipes;

}
/**
 * returns the list of shaped recipes.
 */
public static List<ShapelessRecipes> getShapeless() 
{
	return shapelessRecipes;

}
}

 

i then have a block, which when you right click on it calls the method that loops through your inventory and checks if you have the items required for the stored ShapedRecipe and ShapelessReicpe stored in the lists

		if(recipe.recipeItems.size() == gotRequiredItems)
			avalableRecipes.add(recipe);
	}
	System.out.println(avalableRecipes.size());
	return avalableRecipes;
}
}

 

the last method is called by the block, it then loops through the filtered out "valid" recipes and prints out what you can make.

 

public boolean onBlockActivated(World world, int x, int y, int z, EntityPlayer player, int meta, float float1, float float2, float float3) 
{
	player.addStat(GGUAchievements.usedlazyCrafter, 1);
	//open the gui.
	//get the players inventory.
	//display the inventory and the items avalable 
	//to craft with current items.
	if(!world.isRemote)
	{
		IInventory inventory = player.inventory;
		List invItems = new ArrayList();
		//36-39=armour
		for(int i = 0; i < 35; i++) 
		{
			ItemStack items = inventory.getStackInSlot(i);
			if(items == null)
				continue;
			invItems.add(items);
		}
		List recipes = GGURecipeFilter.filter(invItems);
		for(int i = 0; i < recipes.size(); i++) 
		{
			if(recipes.get(i)instanceof ShapedRecipes) 
			{
				System.out.println(player.getDisplayName()+" can craft a shaped "+((ShapedRecipes)recipes.get(i)).getRecipeOutput().getDisplayName());
			}
			else if(recipes.get(i)instanceof ShapelessRecipes) {
				System.out.println(player.getDisplayName()+" can craft a shapeless "+((ShapelessRecipes)recipes.get(i)).getRecipeOutput().getDisplayName());
			}

		}

		return true;
	}
	return false;
}

}

 

 

it sort of seems to work, it finds some recipes, like it knows when you have 3+ planks, you can make slabs, but it doesn't recognize you can make sticks.

if anyone can make heads or tails of what im mucking up here, your help would be apreciated, thanks.
