Excuse this mess,

public class MIEventHandler {

@SubscribeEvent
public void onInterect(PlayerInteractEvent e) {
	//Following lines of code control creation of chiseled ruby/sapphire using chisel.
	EntityPlayer player = e.entityPlayer;
	ItemStack itemstack = player.getHeldItem();
	World world = e.world;
	int x = e.x;
	int y = e.y;
	int z = e.z;
		if(e.action == e.action.RIGHT_CLICK_BLOCK){
			if(itemstack == new ItemStack(MIMain.chisel)) {
				if(world.getBlock(x, y, z) != null) {
					if(world.getBlock(x, y, z) == MIMain.rubyBlock) {
						world.setBlock(x, y, z, MIMain.chiseledRuby);
						if(!player.capabilities.isCreativeMode) {
							itemstack.setItemDamage(itemstack.getItemDamage() - 1);
					}
				}	else if(world.getBlock(x, y, z) == MIMain.sapphireBlock) {
						world.setBlock(x, y, z, MIMain.chiseledSapphire);
						if(!player.capabilities.isCreativeMode) {
							itemstack.setItemDamage(itemstack.getItemDamage() - 1);
					}
				}
			}
		}

I'm trying to test whether the player has a chisel in their hand, and if they do, then it will check whether they have clicked a sapphire block or ruby block, and if it is, set it to a chiseled version of the block, however, it appears not to be working. Could anyone help me out here?

    What does not working mean?

    Is there a crash?

    Or does it just not do anything. If this is the case, put in debug comments and narrow down the problem.

    One thing I can see wrong for certain is that you check it on both sides, the client and the server.

    Use if(!world.isRemote) to see

    I'm back from being gone for... I think its been about a year. I'm pretty sure nobody remembers me, but hello anybody who does!

    I've already registered the EventHandler @charsmud,

     

    I made a few changes to it, and now it fails to start (previously it would start).

    Not that I know direct answer but there are few flaws in your code:

     

    if(itemstack == new ItemStack(MIMain.chisel))

     

    You should NEVER do this. Don't declare new ItemStack. you should:

    if (stack != null) if (stack.getItem() == YourItemRegistry.itemChiselInstance)

     

    As to main problem: Do you know how to use Debug mode in eclipse? Place breakpoint in your event (maybe even in EACH line) follow them and say when does it crash.

     

    Last question: Are you sure you are using right event bus?

    1.7.10 is no longer supported by forge, you are on your own.

    I am aware of the debug mode in eclipse, however, I cannot use it for some reason (fails to start the client everytime).

     

    I have just checked over myself, and it appears I had not registered my EventHandler. Should be resgistered now.

     

    To answer your last question Ernio, I believe I am using the correct bus, 

    MinecraftForge.EVENT_BUS.register(new MIEventHandler());
