I am trying to make my Altar block, as the code listed here:

 

package com.exomaster.mystictools.blocks;

 

import com.exomaster.mystictools.modhelp.EVReference;

import com.exomaster.mystictools.modhelp.RegisterHelper;

 

import net.minecraft.block.Block;

import net.minecraft.block.material.Material;

import net.minecraft.client.renderer.texture.IIconRegister;

import net.minecraft.creativetab.CreativeTabs;

import net.minecraft.entity.player.EntityPlayer;

import net.minecraft.util.IIcon;

import net.minecraft.world.World;

 

public class Altar extends Block {

public IIcon Side0;

public IIcon Side1;

public IIcon Side2;

public IIcon Side3;

public IIcon Side4;

public IIcon Side5;

 

public static String[] recipes1 = new String[] {"Blocks.glowstone"};

public static String[] recipes2 = new String[] {"Items.diamond"};

 

@Override

public boolean onBlockActivated(World world, int x, int y, int z, EntityPlayer player, int i, float f, float g, float t) {

String item1;

String item2;

 

return true;

}

 

public Altar() {

super(Material.rock);

setCreativeTab(CreativeTabs.tabBlock);

setBlockName(EVReference.modid+"_"+"Altar");

}

 

public void registerBlockIcons(IIconRegister icon) {

Side0 = icon.registerIcon(EVReference.modid + ":altar_bottom");

Side1 = icon.registerIcon(EVReference.modid + ":altar_top");

Side2 = icon.registerIcon(EVReference.modid + ":altar_side");

Side3 = icon.registerIcon(EVReference.modid + ":altar_side");

Side4 = icon.registerIcon(EVReference.modid + ":altar_side");

Side5 = icon.registerIcon(EVReference.modid + ":altar_side");

}

 

public IIcon getIcon(int side, int meta) {

if(side == 0){

return Side0;

} else if(side == 1){

return Side1;

} else if(side == 2){

return Side2;

} else if(side == 3){

return Side3;

} else if(side == 4){

return Side4;

} else if(side == 5){

return Side5;

}

return null;

}

}

 

to look for item entities above it of a certain type, say glowstone. Then look for the 2nd item required to complete the recipe, say a diamond. And after all of that is done, I will need to get rid of the item entities and summon a new one of a certain type. I'm slightly new to modding, so how would I go about doing this?

 

Going off of memory, so beware.

 

Should be able to search for entities of a certain type around your block.  In this case look for EntityItem (verify that name).

 

Once you get the list, go through it and see what item the EntityItem represents and do your thing.
