Hey i get a error while trying to create a recipe

package net.minecraft.src;

public class mod_Redstoneblock extends BaseMod {
	public static final Block redstoneBlock = new BlockRedstoneBlock(201, 0).setHardness(5.0F).setResistance(2.0F).setBlockName("redstoneBlock");
  
	 public void load() {
		 ModLoader.registerBlock(redstoneBlock);
		 redstoneBlock.blockIndexInTexture = ModLoader.addOverride("/terrain.png", "/Redstone/Block.png");
		 ModLoader.addName(redstoneBlock, "Redstone Block");
	 }
	 ModLoader.addRecipe(new ItemStack(Redstoneblock, 1), new Object [] {"UUU", "UUU", "UUU", Character.valueOf('U'), Item.redstone });
public String getVersion() {
	return "1.2.5";
}
}

It says that the dot after ModLoader (Recipe part) is wront, Also the ")" after (Redstoneblock, 1 ")" is wrong

that is because you have it outside the load method, if you look at this line:

public void load() {

the " { " thing is what tells it to start the method, and if you look the first " } " is where that method ends. So to fix this just put your recipe inside the " { } "

Sorry to post again but it seems like minecraft isn't recognising my mod any more.
Here is my code to see if their is something wrong.

 package net.minecraft.src;

import java.util.Random;

public class mod_ElderCraft
{
public static final Block Orichalcum = new BlockOrichalcum(130, 0).setBlockName("Orichalcum Ore").setHardness(3F).setResistance(5F).setLightValue(0F);
public static final Block Ebony = new BlockEbony(131, 0).setBlockName("Ebony Ore").setHardness(3F).setResistance(5F).setLightValue(0F);
public static final Block MoonStone = new BlockMoonStone(132, 0).setBlockName("MoonStone Ore").setHardness(3F).setResistance(5F).setLightValue(0F);
public static final Block Malachite = new BlockMalachite(133, 0).setBlockName("Malachite Ore").setHardness(3F).setResistance(5F).setLightValue(0F);
public static final Block QuickSilver = new BlockQuickSilver(134, 0).setBlockName("QuickSilver Ore").setHardness(3F).setResistance(5F).setLightValue(0F);
public static final Block Silver = new BlockSilver(135, 0).setBlockName("Silver Ore").setHardness(3F).setResistance(5F).setLightValue(0F);
public static final Block Corundum = new BlockCorundum(136, 0).setBlockName("Corundum Ore").setHardness(3F).setResistance(5F).setLightValue(0F);
	   public void load()
	   {
			   Orichalcum.blockIndexInTexture = ModLoader.addOverride("/terrain.png", "/Images/Orichalcu.png");
			   Ebony.blockIndexInTexture = ModLoader.addOverride("/terrain.png", "/Images/Ebony.png");
			   MoonStone.blockIndexInTexture = ModLoader.addOverride("/terrain.png", "/Images/MoonStone.png");
			   Malachite.blockIndexInTexture = ModLoader.addOverride("/terrain.png", "/Images/Malachite.png");
			   QuickSilver.blockIndexInTexture = ModLoader.addOverride("/terrain.png", "/Images/QuickSilver.png");
			   Silver.blockIndexInTexture = ModLoader.addOverride("/terrain.png", "/Images/Silver.png");
			   Corundum.blockIndexInTexture = ModLoader.addOverride("/terrain.png", "/Images/Corundum.png");
			   ModLoader.registerBlock(Orichalcum);
			   ModLoader.registerBlock(Ebony);
			   ModLoader.registerBlock(MoonStone);
			   ModLoader.registerBlock(Malachite);
			   ModLoader.registerBlock(QuickSilver);
			   ModLoader.registerBlock(Silver);
			   ModLoader.registerBlock(Corundum);
			   ModLoader.addName(Orichalcum, "Orichalcum Ore");
			   ModLoader.addName(Ebony, "Ebony Ore");
			   ModLoader.addName(MoonStone, "MoonStone Ore");
			   ModLoader.addName(Malachite, "Malachite Ore");
			   ModLoader.addName(QuickSilver, "QuickSilver Ore");
			   ModLoader.addName(Silver, "Silver Ore");
			   ModLoader.addName(Corundum, "Corundum Ore");


	   }

	   public void generateSurface(World world, Random random, int chunkX, int chunkZ)
	   {
			   for(int i = 0; i < 100000; i++)
			   {
					   int randPosX = chunkX + random.nextInt(16);
					   int randPosY = random.nextInt(128);
					   int randPosZ = chunkZ + random.nextInt(16);
					   (new WorldGenMinable(Orichalcum.blockID, 25)).generate(world, random, randPosX, randPosY, randPosZ);
			   }
	   }


	   public String getVersion()
		 {
						 return "1.2.5";
		 }

}

Also the block gen won't work... In Eclipse, World and Random won't go blue... I don't think it recognises the World.java class. As you can see I changed the spawn rate very high so its not that I just Can't find them....

Thanks again.

~ChillyConCarnage

you forgot at the top, you must do

public class mod_ElderCraft extends BaseMod

Hopefully this fixes it

I have a simple question again Anyone can answer, but how would I make it so zombies (or anything for that matter) spawn in the daylight, and not burn. Again, preferably without editing files. But it will be fine if I have to

Hello. I would like to show you this:

package net.minecraft.src;
public class ConcreteBlock extends Block
{
			    public ConcreteBlock(int i, int j)
			    {
					    super(i, j, Material.rock);
			    }

	    public int idDropped(int , Random random, int j)
	    {
			    return mod_Block.Namehere.blockID;
	    }
	    public int quantityDropped(Random random)
	    {
							    return 1;
	    }}

I don't quite understand what to put in the public int idDropped and public in quantityDropped. Do I need to replace the numbers? Or the random?

Wait, what is the question there? Do you want it to drop more? Or does that snippet of code not work.

	   }

	   public void generateSurface(World world, Random random, int chunkX, int chunkZ)
	   {
			   for(int i = 0; i < 100000; i++)
			   {
					   int randPosX = chunkX + random.nextInt(16);
					   int randPosY = random.nextInt(128);

					   (new WorldGenMinable(Orichalcum.blockID, 25)).generate(world, random, randPosX, randPosY, randPosZ);
			   }
	   }


	   public String getVersion()
		 {
						 return "1.2.5";
		 }

}

Try importing this at the beginning just replace it with the "Random" imported utility.

import java.util.*;

I think your problem is you don't have the "world" imported but just use the code above and you should be fine.

No, I mean, I would like it to drop itself once destroyed and only 1 in quantity. How would I input it? Because it shows error in eclipse.

return mod_Block.Namehere.blockID;

Well, here. I may see a problem... You do need to switch out "mod_Block" with your mod_ file name, and "Namehere" with the block name. I'm not sure about the "blockID"

But other than that, can you tell me where it errors?

Okay, I did that. I replaced them already. Here are some remaining errors:
In line 13, it says that Random cannot be resolved to as a type.
In line 9, it says there is a Syntax error on token "int", VariableDeclaratorId expected after this token.

With the second error, I think you might need to add a letter after the first "int" in the parentheses. With the first, you need some word after "Random"

Sorry, I can't help much more :l I'm not too hotshot of a coder myself

EDIT:
Try this, just change the things like the "mod_Block"

package net.minecraft.src; import java.util.Random; public class ConcreteBlock extends Block { public ConcreteBlock(int i, int j) { super(i, j, Material.rock); } public int idDropped(int i, Random random, int j) { return mod_Block.Namehere.blockID; } public int quantityDropped(Random random) { return 1; } }

Thanks! No more errors! I want to test out this before continuing so, how do I save it? Where do I get the .class files? I already have a texture and what will I do with it? Thanks thanks.

Edit: And btw, what does import java.util.Random; do?

It's what stopped the Random error from happening It defined the Random... So anyway, you have MCP installed? You now just recompile, then reobfuscate the code. When you open the folder entitled "reobf" the class files will be in there.

Thanks! Where do I need to put my custom textures before reobfscating?

Okay missed that one in the OP. Sorry for too many questions, but I have another one. I tested everything and it ran good with the custom textures and such. The block exists now, but it doesn't show up in the items screen in Creative Mode. How to make it show?

That requires some extra line of code that I am not sure of Try looking at some files of other blocks or things. Maybe even in the creative code.

Also, if anyone can answer my question last page, that would be great

If you are making your own mob then you can do it without editing base classes. But if you just want to make the default mobs not burn you can go to EntityZombie (or EntitySkeliton or whatever) and make if so that it extends something like EntityNoSun then just make a new file named EntityNoSun, copy the code from EntityMob, and take out the chunk of code that tells it not to spawn in the daytime, and the chunk that tells it to burn. Or you could just take all that code out of EntityMob.

This looks great! Thanks so much for taking the time to make these. The entity tutorials look SO helpful, and I can't wait until I get my laptop back so I can test them out

OK. Currently, I'm trying to make an Entity of mine spawn structures. I have the structure file ready to go but I am getting errors when I try to get the entity to spawn it. Could there maybe be a tutorial on this?

nice tutorial, but with the custom npc there spawn like 20 of the custom mobs on the same place how to decrease it to 1/2? so I mean how to decrease there spawn rate when generating. hope someone can answer this

If you look in the mob tutorial in the "understanding the code" part, it tells you how to adjust the spawn rate.

Hello, I have a question. I have a mob working and appearing. It attacks me and jumps and everything. I have a few questions though:
1. How to make some of the body parts to move? I know it's somewhere in model****.java, but I don't know what exactly.
2. How to make them like wolves who are neutral then becomes hostile when provoked?
3. Final question, how to make the mob act like the wolves in packs, when once a wolf is hurt, all of them will attack.

Thanks!

BTW, thanks MICHAELNESS for the help.
