how can i make it so a tool turns into a new item when only 1 use remains?
OnItemDestroyedbyUse doesn't work (at all), and OnUpdate for some reason can't reduce the itemstack amount (IE, i can make it drop the tool i want, but i can't make it consume the item).

public void onUpdate(ItemStack itemstack, World world, Entity entity, int i, boolean flag)
{
   
	    if (itemstack.getItemDamage() == itemstack.getMaxDamage())
	    {
		    world.playSoundAtEntity(entity, "mob.blaze.breathe", 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.1F));
		   
		    entity.dropItem(mod_EXPower.DepletedPick.shiftedIndex, 1);			
		 
		  
		    itemstack.setItemDamage(11);
		    itemstack.stackSize = 0;
		  
	    }
		    return;
	    }

@last two
I have no idea.

And TechGuy, would you have any idea on how to make a new crafting thing with ModLoader?

I'm working on a mod and everything is alright if I recompile my .class files.
But when I start the test client, Modloader gives these errors

Godstone:

package net.minecraft.src;

  public Godstone (int i, int j)
  {
   super(i, j, Material.wood);

	 }}

If someone could help me I would greatly appreciate it!!

Did you save them as .class files? If so, that's wrong. They should be .java files.

In your recipe, it should be this:

ModLoader.addRecipe(new ItemStack(Godstone, 1), new Object []{"#", Character.valueOf('#'), Block.stone})

So for making tools, it requires ALL of those class files?

Hi, I tried using the custom npc tutorial. My mob spawns fine, but it doesn't hold my item. Here is my code, where did I go wrong?

I wouldn't include them if they weren't needed

but nothing is happening when i kill the mob other than it dying silently

please help me - id prefer to use than than to use AudioMod :/

Please tell me what i am doing wrong - thank you!!

It is impossible to read that code with all of those html tags. From what I can see though, you need to change the sound method to just return the String and not the method to play sounds.

protected String getDeathSound()
{
	 return "mob.spottedgrannymod.grannydead";
}

Post your render code.

TechGuy can you plz do these tutorials

bow/gun
furnace
how to add enum stuff with out editing base classes
grow able plants like weat

Not taking requests, I've done the third one anyway. The rest except the furnace are on the to-do list. Look before you post.

how do you know if your texture is the right size?

Windows Explorer or the Mac File Browser.

Thanks TechGuy. It's nice to see some quality written tuts with templates, and an understanding that sensible people actually like to know what they are doing.

I'd been going nuts watching video tuts made by guys who just waved the mouse around and said "likeawesomedudecitywhatevermanyeahwellitshouldwork" and the very thing you want to know they don't know either.

Great work. Don't go rotten as you enter middle teen age.

Your code looks like it should work but there is one thing that may be stopping it from doing so. Changing the if statement to this will most likely fix your issue.

if (itemstack.getItemDamage() == 1)

I think it is fairly easy to understand what I did but just ask if you're unsure.

Why are the pixels in the ingot i made all fat?

TechGuy, would you know how to open a gui with ModLoader?

Pixels are always the same size

Quote from Stronghold257

TechGuy, would you know how to open a gui with ModLoader?

I don't know how to use ModLoader.openGui but I do know that you can use:

mc.displayGuiScreen(new GuiNamehere(world, entityplayer/*and any other args*/);

Where mc is the Minecraft instance. I can only assume you use the ModLoader method the same way, but it does the same thing anyway.

No I swear its perfectly fine but when i go into the game the pixels on it are all weird!

Example:


See how some of the pixels are messed up? How do i fix that?

Im making the tools for my mod and i cant figure out how to fix this error:
