I am wanting to create an event to do something rather strange...

What I want is: when a player right clicks a gold block with a flint and steel I want it to spawn another gold block on top of it instead of fire

I tried using events but I just can't wrap my head around it.

Any help would be useful!

Post what you tried.

That's the thing, I haven't got anything apart from a class, I'm not entirety sure how to check/cancel the event.

You can read up about events here.

Okay, so I've managed to get this...

public class TestEvent
{
	public void exampleEvent(PlayerInteractEvent event)
	{
		World world = event.getWorld();
		EntityPlayer player = event.getEntityPlayer();
		ItemStack itemstack = player.getHeldItemMainhand();
		BlockPos pos = event.getPos();
		

		
		if(itemstack == new ItemStack(Items.FLINT_AND_STEEL))
		{
			
		}
		
	}

}

But I'm not sure where to go from it

PlayerInteractEvent

There are several sub-events to this one, the one you want is called PlayerInteractEvent.RightClickBlock.

You have the BlockPos where the player right clicked(aka where the Block is in the World where they right clicked). That means you have access to which Block they right clicked. Check to make sure it was a Gold Block. If it was a Gold Block then use BlockPos#offset to offset in the UP direction and call World#setBlockState to put a Gold Block in the World at that offset position.

	{
		World world = event.getWorld();
		EntityPlayer player = event.getEntityPlayer();
		ItemStack itemstack = player.getHeldItemMainhand();
		BlockPos pos = event.getPos();
		IBlockState state = world.getBlockState(pos);
		Block block = state.getBlock();
		

		
		if(itemstack == new ItemStack(Items.FLINT_AND_STEEL) && block.equals(Blocks.SOUL_SAND))
		{
			BlockPos fire = pos.offset(EnumFacing.UP);
			world.setBlockState(fire, Blocks.GOLD_BLOCK.getDefaultState());
		}
		
	}

}

But nothing seems to happen in game, it still places the fire

Is your event even being called? Where do you register it?

I made a new class - EventHandler and added this to it:

public static void registerEvents()
	{
		TestEvent testEvent = new TestEvent();
	
		MinecraftForge.EVENT_BUS.register(testEvent);
	}

Then in my RegistryHandler (where the FMLInitialization events are) I have this in the preInit:

EventHandler.registerEvents();

I'm guessing it has something to do with the fire being placed first?

@SubscribeEvent

So where does this exactly go? I'm confused by the wording in the docs

I was the blind one this time diesieben

It goes right above your Event method.

It goes right above your Event method.

So:

	@SubscribeEvent
	public void exampleEvent(RightClickBlock event)
	{
		World world = event.getWorld();
		EntityPlayer player = event.getEntityPlayer();
		ItemStack itemstack = player.getHeldItemMainhand();
		BlockPos pos = event.getPos();
		IBlockState state = world.getBlockState(pos);
		Block block = state.getBlock();
		

		
		if(itemstack == new ItemStack(Items.FLINT_AND_STEEL) && block.equals(Blocks.SOUL_SAND))
		{
			BlockPos fire = pos.offset(EnumFacing.UP);
			world.setBlockState(fire, Blocks.GOLD_BLOCK.getDefaultState());
		}
	}

This still isn't doing anything

Can you confirm if the event is being fired. Put a print line there or better yet step through that method with your debugger.

Put a print line there

I have added 2 print lines (Event Failed, and Event Success), every time I right click with a flint and steel, the Event Failed comes through, even if I am aimed at soul sand

However, just right clicking is bringing up the message as well

itemstack == new ItemStack(Items.FLINT_AND_STEEL)

We were both blind diesieben...

The problem is that this will never be true. Use ItemStack#getItem and compare item instances instead.

Just now, diesieben07 said:

Post updated code (with the debug message).

@SubscribeEvent
	public void exampleEvent(RightClickBlock event)
	{
		World world = event.getWorld();
		EntityPlayer player = event.getEntityPlayer();
		
		ItemStack itemstack = player.getItemStackFromSlot(EntityEquipmentSlot.MAINHAND);
		BlockPos pos = event.getPos();
		IBlockState state = world.getBlockState(pos);
		Block block = state.getBlock();
		

		if(itemstack == new ItemStack(Items.FLINT_AND_STEEL))
		{
			System.out.println("Tested and Found Flint And Steel");
			if(block == Blocks.SOUL_SAND.getDefaultState())
			{
				BlockPos fire = pos.offset(EnumFacing.UP);
				world.setBlockState(fire, Blocks.GOLD_BLOCK.getDefaultState());

				System.out.println("Event Success");
			}
		}
		else
		{
			System.out.println("Event Completely Failed");
		}
		
	}

And in the console: 

[19:17:54] [main/INFO] [STDOUT]: [club.mcmodding.netherupdate.events.TestEvent:exampleEvent:43]: Event Completely Failed
[19:17:54] [Server thread/INFO] [STDOUT]: [club.mcmodding.netherupdate.events.TestEvent:exampleEvent:43]: Event Completely Failed

Animefan is right.

Please learn basic Java (yes, the == operator is basic Java) before attempting to mod.

Yes, I see that now, however, there is still the problem with the block, as it is not being detected

block == Blocks.SOUL_SAND.getDefaultState()

Look at the return type of Block#getDefaultState... they aren't compatible.
