Any idea when the next tutorial will be out?

Shouldn't take too long now that I've decided that there is no easy way to smelt with metadata

Does that mean all items/blocks that you want to be smelted cannot use metadata?

No, it's easy enough to have the output with metadata, but it doesn't look like it's going to be simple to have metadata input :/

Can i use metadata with armor? and if so what changes do i make to the code?

for example:

These would be the normal calls in the main mod file for a normal armor set


and this would be the normal Item file


now say i wanted to have one for each color. but i wanted them to be the same other than the textures and names...
what would i do to make this happen?

each image file has a name like... "simplearmorblue_1, simplearmorblue_2"

public static Item armorsimpleHelmet;
public static Item armorsimplePlate;
public static Item armorsimpleLegs;
public static Item armorsimpleBoots;

public static int idsimpleHelmet;
public static int idsimplePlate;
public static int idsimpleLegs;
public static int idsimpleBoots;

@PreInit
public void preInit(FMLPreInitializationEvent event)
{
event.getModMetadata().version = "1.3.2";
Configuration config = new Configuration(event.getSuggestedConfigurationFile());
config.load();
	
idsimpleHelmet = Integer.parseInt(config.getOrCreateIntProperty("idsimpleHelmet", Configuration.CATEGORY_ITEM, 4100).value);
idsimplePlate = Integer.parseInt(config.getOrCreateIntProperty("idsimplePlate", Configuration.CATEGORY_ITEM, 4101).value);
idsimpleLegs = Integer.parseInt(config.getOrCreateIntProperty("idsimpleLegs", Configuration.CATEGORY_ITEM, 4102).value);
idsimpleBoots = Integer.parseInt(config.getOrCreateIntProperty("idsimpleBoots", Configuration.CATEGORY_ITEM, 4103).value);
	
config.save();
}

EnumArmorMaterial armorsimple = EnumHelper.addArmorMaterial("simple", 100, new int[] {1, 4, 4, 2}, 15);
int renderersimple = proxy.addArmor("simpleArmor");

armorsimpleHelmet = new SimpleItemArmor(idsimpleHelmet, armorAdven, renderersimple, 0).setItemName("armorsimpleHelmet").setIconIndex(128);;
armorsimplePlate = new SimpleItemArmor(idsimplePlate, armorAdven, renderersimple, 1).setItemName("armorsimplePlate").setIconIndex(128);;
armorsimpleLegs = new SimpleItemArmor(idsimpleLegs, armorAdven, renderersimple, 2).setItemName("armorsimpleLegs").setIconIndex(130);;
armorsimpleBoots = new SimpleItemArmor(idsimpleBoots, armorAdven, renderersimple, 3).setItemName("armorsimpleBoots").setIconIndex(131);;

		 LanguageRegistry.addName(armorsimpleHelmet, "simple Helmet");
		 LanguageRegistry.addName(armorsimplePlate, "simple Chest Plate");
		 LanguageRegistry.addName(armorsimpleLegs, "simple Greaves");
		 LanguageRegistry.addName(armorsimpleBoots, "simple Boots");

and this would be the normal Item file

public class SimpleItemArmor extends ItemArmor implements IArmorTextureProvider
{

				 public SimpleItemArmor(int i, EnumArmorMaterial enumarmormaterial, int j, int k)
				 {
								 super(i, enumarmormaterial, j, k);
				 }
	
				 public String getTextureFile()
				 {
								 return "/SimpleItems.png";
				 }

				 public String getArmorTextureFile(ItemStack itemstack)
				 {
								 if(itemstack.itemID == Simple.armorsimpleHelmet.shiftedIndex || itemstack.itemID == Weave.armorsimplePlate.shiftedIndex || itemstack.itemID == Simple.armorsimpleBoots.shiftedIndex)
								 {
												 return "/simplearmor_1.png";
								 }
								 if(itemstack.itemID == Simple.armorsimpleLegs.shiftedIndex)
								 {
												 return "/simplearmor_2.png";
								 }
								 return "/simplearmor_1.png";
				 }
}

I'm not terribly experienced with armour, but it shouldn't be too hard to do metadata. You'll need to use getIconFromDamage and getItemNameIS to start with, but I'm not sure if there is actually a method for metadata with armour textures, I'll check it out

for a block with metadata I did this

in the main file


and


in the block file

then made a ItemBlock file like this


but in this process i make the "block" into a "item" in a way to hold the data i need...

I don't know how to hold the data i put in the "block" file in the "item" file, nor do i know how to handle the


of each "color" all in one file. I assume with if statments....


like that and repeat for each type then put a "default" at the end....

LanguageRegistry.instance().addStringLocalization("tile.simpleblock.simple.name", "Simple Block");

I prefer switch statements for metadata textures... For the armour texture itself you can switch the itemstack's getItemDamage() method

Omg Omg Omg Cant wait for tutorial #8!!! Any ETA?

Thanks,

Hi thanks for the tutorials, i'm following you.
But i've a question to you: how can i cshare my mods with my friends? When i download a mod(compatible with forge) i put it in mods folder, and it works, how can i make it?

When your mod is in working condition, run the recompile.bat program. Then run reobf.bat. You need to navigate to the folder, and copy your mod's package into a zip file, and don't forget to add the gfx folder

Shouldn't be too long, just a bit busy with exams at the moment

can you refrase the need forge becouse you need the src not forge

Quote from Disema

I tried the second tutorial but if i copy the code it give me an error:

public String getItemNameIS(ItemStack i){
try{ //Just in case of NullPointerException
		 return names[i.getItemDamage()];
}catch(Exception e){
return "";
}
}

near names, i downloaded the source code of the next tutorial and the code is:

public String getItemNameIS(ItemStack i){
switch(i.getItemDamage()){
case 0:return "Sapphire";
case 1:return "Amethyst";
case 2:return "Topaz";
default:return "";
}
}

I used this and it works.
And in this tutorial you forgot to say that you must add:

import net.minecraft.src.ItemStack;

In the main file.



and yes, if you go in FML page there are two download...

Yeah, I know there are issues with the second tutorial, I though I'd changed it... I'll fix it now though

texture white your texture and mine

Quote from Disema

I'm trying to add a new fuel from metadata item, but i don't know how can i chose the sub item, all items form metadata burn in furnace...

this is the code:
in main file(prima_prova.java):

GameRegistry.registerFuelHandler(new NewFuel());

in NewFuel.java:

package disema.prima_prova;

import net.minecraft.src.ItemStack;
import cpw.mods.fml.common.IFuelHandler;

public class NewFuel implements IFuelHandler {
@Override
public int getBurnTime(ItemStack fuel) {

if(fuel.itemID == prima_prova.metaGem.shiftedIndex)
return 1000;
else
return 0;
}
}

can i show only one item from metadata item?

At the if statement, add

&& item.getItemDamage() == ***

You could also have a switch statement inside the if statement switching the item damage

Quote from Disema

I don't understant, what are the ***? and item? i must use metaGem? this class haven't getItemDamage() method.
the same for switch statement

By the way, thanks for help

Sorry, when I have *** I mean your own object, so for my example, *** would be the metadata you need, and by item I meant fuel, sorry for being vague

Quote from Disema

sorry but i could not create this by the way if i'll need to create a new fuel i will not use metadata :|

now i've an other problem, i'm trying to generate new ore (i'm following your tutorial so i'm trying to generate BlockGEM in the world) but when i try it in the console appear this:

Warning: Texture /gfx/Blocks.png not preloaded, will cause render glitches!

Any known bug?

Don't worry, it's nothing, the textures still render fine I think it's just from having the textures in the common package

Quote from MincraftWero

I'm hoping you will make an mcmod.info tutorial

Probably

I keep getting an error when I try to do the import cpw thingy. I'm such a noob at this stuff...

Quote from Jstorey97

Great tutorials They are very good and i will have a look at that item meta-data code I like it Anyway can you do a liquid tuorial? Assuming the liquids can be picked up by an iron bucket. And im looking forward to that config tuorial.

Liquid tutorial will come eventually, but for now I've got to get my ore generation to behave

Which import is broken and what is the error?

Great job on these tutorials. They've been immensely helpful, even though they'll probably be obsolete within the next few months... but that's beside the point.

I was wondering, is it possible to use infinite sprite indices without making a separate class for each item? I've been trying, but it always defaults to the Items.png for some reason.(But maybe I just have my textures in the wrong place... they're in MCP\eclipse\Minecraft\bin\mytextures.) I have some items in my mod that don't do much and I feel it would be a waste to make a class for each one rather than just having them in my main class.

Again, thanks for these.

If you want to, you can just add classes to the end of your mod class, but it might start to get slightly long There is another way it could work easily, but I'll have to think it over a bit. The textures have to go in the common folder
