I was thinking that it might be good for you to add the mob spawner to the generation tutorial, so that other people could also get it to work, the code I used looked like this:

 world.setBlockWithNotify(i +3, j, k +1, Block.mobSpawner.blockID);
	    TileEntityMobSpawner tileentitymobspawner = (TileEntityMobSpawner)world.getBlockTileEntity(i +3, j, k +1);

	    if (tileentitymobspawner != null)
	    {
		    tileentitymobspawner.setMobID(pickMobSpawner(random));
	    }
	    else
	    {
		    System.err.println((new StringBuilder()).append("Failed to fetch mob spawner entity at (").append(i).append(", ").append(j).append(", ").append(k).append(")").toString());
	    }

//end of test

		    return true;
}
return false;

}
//test
    private String pickMobSpawner(Random random)
    {
	    int i = random.nextInt(4);

	    if (i == 0)
	    {
		    return "Skeleton";
	    }

	    if (i == 1)
	    {
		    return "Zombie";
	    }

	    if (i == 2)
	    {
		    return "Pig";
	    }

	    if (i == 3)
	    {
		    return "Spider";
	    }
	    else
	    {
		    return "";
	    }
    }
//end


}

And that will work, but only if the area around the mob spawner fulfills the conditions for the mob to spawn, the importent things to note are: the (i, j, k) positions for the block and tileentity have to be the same, the last chunk of code goes after the "return false line", and if you want only one mob to spawn you just have to change all the 'return "Nameheres"' to the same mob. I just thought that you might like to add that to your tutorial on structure generation. Now I think I will try to get chests to work

Thanks I might add that later. I'm sure you could probably figure it out yourself, but strength has a tutorial on generating chests with contents. It looks like it will work. You'll just need to fix the GenerateSurface method to suit 1.2 ModLoader.

Oh, thanks, it will be much easier if I have something to start with, even if it is outdated.
Oh, and by the way, I think that the error I was getting before was because some of the "random"s were the wrong case (so they were caps when they were not suppose to)

I dont understand, the hugeexplosion effect only gives me large amount of TNT explosion smoke, meanwhile the "

float f = (rand.nextFloat() - 0.5F) * 8F;

float f1 = (rand.nextFloat() - 0.5F) * 4F;
float f2 = (rand.nextFloat() - 0.5F) * 8F;"
seem to be doing nothing, I dont understand

I tried to make a smelting recipe to smelt a new block into another new block, but when I try to recompile it gives me this error:

Here's the mod_RedstonePlus file:

package net.minecraft.src;

public class mod_RedstonePlus extends BaseMod

public static final Block RedstoneBrick = new BlockRedstoneBrick(163, 0).setBlockName("Redstone Bricks").setHardness(10F).setResistance(20F);
public static final Item RedstoneDrink = new ItemFood(5001, 10, 1F, false).setItemName("Redstone Drink");
public static final Block DustedStone = new BlockDustedStone(164, 0).setBlockName("Dusted Stone").setHardness(3F).setResistance(6F);
public static final Block RedSTONE = new BlockRedSTONE(165, 0).setBlockName("redSTONE").setHardness(6F).setResistance(12F);

		public void load()
		{
				RedstoneBlock.blockIndexInTexture = ModLoader.addOverride("/terrain.png", "/RedstonePlus/RedstoneBlock.png");
				RedstoneStairs.blockIndexInTexture = ModLoader.addOverride("/terrain.png", "/RedstonePlus/RedstoneStairs.png");

				DustedStone.blockIndexInTexture = ModLoader.addOverride("/terrain.png", "/RedstonePlus/DustedStone.png");
				RedSTONE.blockIndexInTexture = ModLoader.addOverride("/terrain.png", "/RedstonePlus/RedSTONE.png");
				ModLoader.registerBlock(RedstoneBlock);
				ModLoader.registerBlock(RedstoneStairs);
				ModLoader.registerBlock(RedstoneSlab);
				ModLoader.registerBlock(RedstoneBrick);
				ModLoader.registerBlock(DustedStone);
				ModLoader.registerBlock(RedSTONE);
				ModLoader.addName(RedstoneBlock, "Block of Redstone");
				ModLoader.addName(RedstoneStairs, "Redstone Stairs");
				ModLoader.addName(RedstoneSlab, "Redstone Slab");
				ModLoader.addName(RedstoneBrick, "Redstone Bricks");
				ModLoader.addName(RedstoneDrink, "Redstone Drink");

				ModLoader.addName(RedSTONE, "RedSTONE");

				ModLoader.addRecipe(new ItemStack(RedstoneBlock, 6), new Object [] {"#  ", Character.valueOf('#'), RedstoneStairs});
				ModLoader.addRecipe(new ItemStack(RedstoneSlab, 3), new Object [] {"###", Character.valueOf('#'), RedstoneBlock});
				ModLoader.addRecipe(new ItemStack(RedstoneBlock, 1), new Object [] {"#  ", Character.valueOf('#'), RedstoneSlab});
				ModLoader.addRecipe(new ItemStack(RedstoneBrick, 1), new Object [] {"## ", "## ", Character.valueOf('#'), RedstoneBlock});
				ModLoader.addRecipe(new ItemStack(RedstoneBlock, 4), new Object [] {"#  ", Character.valueOf('#'), RedstoneBrick});
				ModLoader.addRecipe(new ItemStack(RedstoneDrink, 1), new Object [] {" # ", " $ ", Character.valueOf('#'), Item.redstone, Character.valueOf('$'), Item.glassBottle});
				ModLoader.addRecipe(new ItemStack(DustedStone, 1), new Object [] {"###", "#$#", "###",  Character.valueOf('#'), Item.redstone, Character.valueOf('$'), Block.stone});
				ModLoader.addSmelting(DustedStone, new ItemStack(RedSTONE, 1));

		}

		public String getVersion()
		  {
						  return "1.2.4";
		}
}

I would say that is is because you have "RedSTONE" not "redstone" in this chunk of code:

			    ModLoader.addSmelting(DustedStone, new ItemStack(RedSTONE, 1));

If you post your code and error report. then yes, someone could help you. Please realize that there is a multitude of different things that could have caused that, and from just that small snippet of the error, no one could tell you what was wrong (we could guess, but that is about it), were as if you post your code (and error report) other more experienced modders can look at it and actually see what the problem is, and therefor help you fix it.

I know, that's one of the 2 new blocks, the first is DustedStone, the 2nd is RedSTONE

Oh, sorry Um, I think that you need to add ".blockID"
to this line:

ModLoader.addSmelting(DustedStone, new ItemStack(RedSTONE, 1));

so that it looks like this:

ModLoader.addSmelting(DustedStone.blockID, new ItemStack(RedSTONE, 1));

If that doesn't work (it should, but in case it doesn't) try this:

ModLoader.addSmelting(mod_RedstonePlus.DustedStone.blockID, new ItemStack(mod_RedstonePlus.RedSTONE, 1));

It was sort of a guess but I used that tutorial ages ago and it took them like over an hour to explain stuff. I followed what they did, and it didn't even work, with 1.1 anyway.

lol yeah , i plan on making a better tutorial version of it later on since i finally got it to work ( 4hrs later )
now to just find a good block/item id extension tutorial =D

there is all the classes i have added to the game but i get an error when i start minecraft

firstly: to make the spoiler you need to put a "/" in the last [] so that you have [/spoile]
secondly: if the game crashes when you start minecraft it is most likely that your pictures are not linked properly, but it is hard to say if you don't post the error/crash report that you got.

i alredy knew i needed to use forge ... but i was wondering if it could be done with out it

and even with forge i cant figure it out .. can you teach me ? on how to use cordinates ??
i relay whant to use my own pgn

greets

I don't know how to do it without Forge, or even how to do it with Forge. I just know it has that feature. As I said on the last post, the other coder on the Undead+ team is trying to work this out.

Quote from EarthGuardian

hey me again

i have another uestion. i gues using my own png is to far away becose it need forge .. thats realy sad... becose i dont whan tmy mod to ened modloader and forge .. to be used lol

anny way do you know about static ID's ??

for example sapling had ID 6 but there 3 kinds of saplings 6:0, 6:1, 6:2 ... that means it had the block ID 6 but an offset :0- :2 .. how can i do this ? with my blocks? becose i whant to add alot of block and MC ID's are limited not to mention other mods use ID's too
so i whant to give my blocks the offset like saplings do or stone slab 44:0 44:1 44:2

how can i do this ??

greets

It is on the list to do (Damage-Value Blocks)

Quote from BigZee

I dont understand, the hugeexplosion effect only gives me large amount of TNT explosion smoke, meanwhile the "

float f = (rand.nextFloat() - 0.5F) * 8F;

float f1 = (rand.nextFloat() - 0.5F) * 4F;
float f2 = (rand.nextFloat() - 0.5F) * 8F;"
seem to be doing nothing, I dont understand

You need to learn Java, at least a bit of it.

float f = (rand.nextFloat() - 0.5F) * 8F; float f1 = (rand.nextFloat() - 0.5F) * 4F; float f2 = (rand.nextFloat() - 0.5F) * 8F; worldObj.spawnParticle("hugeexplosion", posX + (double)f, posY + 2D + (double)f1, posZ + (double)f2, 0.0D, 0.0D, 0.0D);

As you can see in that last line, f, f1 and f2 are all referenced too. If you change the values of those floats, then you can change the particle size. It may not be the giant thing that happens when the Ender Dragon dies, but this is the only thing I found in its class. You'll have to do some looking yourself.

Quote from Guest93

Is there a way to remember the coordinates of where you teleported to an other dimension?
Example:

I make somewhere an portal of my dimension and land somewhere in the other dimension.

When I go back, I land where I entered the portal.

And now the difficult part (for me): When I build somewhere else an portal, I land at the first portal in the other Dimension.

But if I go back, I land againt at the portal, I started (this time the second)
Is this somehow possible??

PS: I use atm the Standard Portal-Code of the Nether

I don't know. Please go and ask in Mod Development. This isn't a help thread, it is a tutorials thread, and I am only helping people who are using my tutorials and are having trouble.

Then there is a problem with ModLoader. I can't do anything about it.

When doing mine, I just set its ID to 1, so that it overwrites plains. It seems to make it a lot easier to find. Don't forgot to change the ID back though when you're done testing!

Try changing the null to a 0 in your public static final line.
