Hi everyone,

 

I want to know how can I check close items, or blocks. For example, if I have fire 1 square around me I want to give ench. to my sword. How can I check and change itemicon?

 

Secondly, when I eat custom foods with BOWL I want to give bowl back to me.  Like water when you use it, it gives bucket back. How can I do this?

 

Thanks

The food is easy, add something like this to you class;

 

    @Override
public ItemStack onEaten(params)
    {
        super#onEaten(params);
        return new ItemStack(Whateveryouwantinreturn);
    }

 

The enchantment thing took me a while, but I finally got it to work in a clean manner.

 

if (player#worldObj#getBlockId((int)player#posX, (int)player#posY - 1, (int)player#posZ) == Blockwhateveryouwant)

        {
            	ItemStack sword = player#getCurrentEquippedItem();
            	
            	if(sword#isItemEnchantable())
            	{
            	
            		if(!sword#isItemEnchanted());
            		{
            			sword#addEnchantment(whateverenchantment you want);
            		}
            	}
            }

 

The above code goes in your TickHandler, if you don't have one of those, go make one(I'll wait).

 

First it looks at the block below you; if it matches the block you specify, it will go to the first "if statement". Next, it will look at the player is currently holding and asks if it is enchantable, if it is, proceed to the next "if statement". If you are at this stage, it means that you are standing on your specified block, and the item that you are holding is enchantable. The next "if statement' checks to see if the enchantable item you are holding is already enchanted, if it is, nothing happens, if it isn't the enchantment(s) that you specify will be applied to the weapon.

 

i don't have time to check right now, but as far as the itemIcon goes, you may want to look into "getItemDamageForDisplay".

 

 

(Just for fun)

Try and take out one of the "if statements' and see what is does.

 

 

 

If you remove "!player.isItemEnchanted" for instance, the same enchantment(s) will be applied every tick,(20 times every second, I believe) and your game will more than likely crash.

 

 

 

 

 

I hope I helped, and you learned something that you can apply to your future modding endeavors!

firstly, thank you about informations because they are very instructive. I think after half an hour I will have time to check, and I will write feedback

 

Thank you so much

For item.bowlempty is working now thank you.

 

However, I working eclipse for 3 days and I don't know what is TickHandler, could you explain me little bit more, please? I looked to internet but couldn't find, or if I can, I didn't know And also how can I check distance between item

A Tickhandler basically checks something on an event. For example, I am using my Tickhandler to check if a player falls in my custom dimension, and if they do, then I want the fall damage to be reduced significantly. Here is the outline of a basic Tickhandler:

 

 

 

public class YOURTICKHANDLER implements ITickHandler {

 

@Override

public void tickStart(EnumSet<TickType> type, Object... tickData) {

}

//This is an example of an event, you need to put @ForgeSubscribe in front of it so Forge knows It is an event. Then you need to specify an event type in the same way I did the Living fall event.

@ForgeSubscribe

public void livingFall(LivingFallEvent event)

{

}

 

 

@Override

public void tickEnd(EnumSet<TickType> type, Object... tickData) {

 

}

 

@Override

public EnumSet<TickType> ticks() {

 

        return EnumSet.of(TickType.PLAYER, TickType.SERVER);

 

}

 

@Override

public String getLabel() {

 

return null;

}

 

}

 

And that is your basic Tickhandler.

 

Hope that helps.

 

EDIT: To register your TH, you need to put this in your main class:

 

TickRegistry.registerTickHandler(new NAMETickHandler(), What ever side your tickhandler needs to be on, probably Side.SERVER, but it could be Side.CLIENT, I'd recommend Side.SERVER though.);

The tick handler will allow you to "focus" on the player(CJ said it better), allowing you to do neat things like potion effects.

 

Here is a video showing how to set one up,

 

 

...and one showing potion effects

 

 

Locating blocks can be a bit...tricky.

 

You have three ways to move, "X", "Y", and "Z"

 

The "Y" axis is the easiest, it is up/down. Up is represented by positive numbers, down by negative. From the example I gave you,

(int)player#posY - 1

you can see that the game is looking one block below the player's feet. (Represented by cobblestone)

I believe "X" is the East direction, and "Z" is South. Unfortunately, my project is acting up at the moment, so I can't get screenshots of those two.  I did, however find a "compass" that may help.

 

 

 

 

 

 

Play around with them yourself, though! Anyone can tell you how to do it forever, but you are never going to learn unless you actually do something. ;P

Thank you so much, these messages are helpful for me. I check and test something like this;

I understand how it works, but I only stuck when I try to change icon, for example I want to change my blackDiamondSword to blackDiamondBow, but I couldn't find registericon, seticon, or something like this. Is it possible to do? And also I don't want only equiped item change, I want if I have in my bag, it change, if its possible

 

If you explain how can I, I can try

Override one of the getIcon method in Item class. Then return the icon that fits your need.

It needs to be registered once with IconRegister before being displayed. Item has a registerIcons method for that.

I have registerIcon setting under my item class, but I'm not really understand how can I add getIcon settings under this,

I added some items but I have a problem because I add addsmelting but not working on foods.

 

My drink;

Configref;

        cupOfMilkyChocolateID = config.get("Drink IDs", "Cup Of Milky Chocolate ID", 3386).getInt();
        cupOfHotMilkyChocolateID = config.get("Drink IDs", "Cup Of Hot Milky Chocolate ID", 3387).getInt();

 

Foodref;

	this.cupOfMilkyChocolate = new addcanfood(configref.cupOfMilkyChocolateID, "cupofmilkychocolate", 6, 0.5F, false, 0, itemref.cup);
	this.cupOfHotMilkyChocolate = new addcanfood(configref.cupOfHotMilkyChocolateID, "cupofhotmilkychocolate", 6, 0.8F, false, 1, itemref.cup);	

 

Smelting;

        GameRegistry.addSmelting(smelt_ore_diamond_black_id, craft_ingot_diamond_black, 0.9f);
        GameRegistry.addSmelting(smelt_ore_night_id, craft_ingot_night, 1.0f);

        GameRegistry.addSmelting(smelt_cup_chocolate_id, craft_cup_chocolate_hot, 0.8f);
        GameRegistry.addSmelting(smelt_cup_milk_id, craft_cup_milk_hot, 0.8f);
        GameRegistry.addSmelting(configref.cupOfMilkyChocolateID, new ItemStack(foodref.cupOfHotMilkyChocolate), 0.8f);        

 

And addcanfood;

	}
        
        return itemstack.stackSize > 0 ? itemstack : new ItemStack(this.returnItem);

}

 

The problem is, smelting, the first 2 item which are ores, working but when I try to cook my drinks it isn't possible, I tried to fix it 3 hours but I couldn't because I don't understand where is the mistake.

 

Can anyone help my about this please, thanks.
