How to install mods
Open Me
Are you on a Mac? Well you’re paying to much for an average computer…
http://youtu.be/http://www.youtube.com/watch?v=6-LPvijRUjM
Are you on a Windows Computer? 88) aa)
here is your tutorial:
first press Windows Key + R
type
%appdata%\.minecraft\bin\
now get a archiving program that can open the .jar file, I recommend WinRAR but 7zip and WinZIP work too.
copy the Minecraft.jar and save it as Minecraft -Backup.jar or whatever you want (this is a backup just incase you screw up)
Now open the Minecraft.jar file with your archiving program and delete the META-INF folder.
Now drag the mod files that you downloaded. Let it overwrite the files because it will save the changes that way.

examples
return Block.grass.blockID;
return Item.clay.shiftedIndex;
HELP: mod_Namehere
At new BlockNamehere(190,
change 190, that is the block ID be careful not to use the same ID again
At .setHardness(1.0F)
change the 1.0, dirt is 0.5; stone is 1.5; 10 is unbreakable
At .setResistance(2500.0F)
this is how resistant the block is to Explosives
change the 2500.0, obsidian is 2000.0F all other blocks are 5.0F
At .setLightValue(1.0F)
this is how bright your block is
1.0F is as high as it goes, Torches are 0.9375F and redstone is 0.5F
At ModLoader.AddName(Namehere, “Nameingamehere”);
this is the ingame name, so change Namehere to the block name (in mod_Namehere) and change Nameingamehere to whatever you want it to say ingame
At Namehere.blockIndexInTexture = ModLoader.addOverride("/terrain.png", “/Namehere.png”);
this is the texture, change the Namehere.blockIndexInTexture and in the () change “/Namehere.png” ex. “/Mod/Fireblock.png” the /Mod/ is a folder and the Fireblock.png is the image file

Creating a Slab Block[details=Open Me]
the mod_Namehere class will not be altered in this tutorial.
BlockNamehere
package net.minecraft.src;
import java.util.Random;
public class BlockNamehereSlab extends Block
{
protected BlockNamehereSlab(int i, int j)
{
super(i, j, Material.wood);
setBlockBounds(0.0F, 0.0F, 0.0F, 1.0F, 0.5F, 1.0F);
setLightOpacity(255);
}
public boolean isOpaqueCube()
{
return false;
}
public int idDropped(int i, Random random, int j)
{
return mod_Slab.Namehere.blockID;
}
public int quantityDropped(Random random)
{
return 1;
}
public boolean renderAsNormalBlock()
{
return false;
}
public boolean shouldSideBeRendered(IBlockAccess iblockaccess, int i, int j, int k, int l)
{
if (this != Block.stairSingle)
{
super.shouldSideBeRendered(iblockaccess, i, j, k, l);
}
if (l == 1)
{
return true;
}
if (!super.shouldSideBeRendered(iblockaccess, i, j, k, l))
{
return false;
}
if (l == 0)
{
return true;
}
else
{
return iblockaccess.getBlockId(i, j, k) != blockID;
}
}
}
setBlockBounds in the constructor of the block class is what makes you able to walk over it. 1F, 0.5F, and 1F are the length, height and width of the block, respectively.
The shouldSideBeRendered method is one that I can’t seem to figure out. I have used the block with and without this code, next to stairs and such, but it doesn’t seem to make a difference. I have left it in the tutorial in case someone does run into a few lighting issues when the block is next to stairs.[/details]

This is just like making an item except you dont need to make ItemNamehere.java files!
now for the only difficult part. find EnumToolMaterial.java file and open it up
at the top where it says
WOOD(“WOOD”, 0, 0, 59, 2.0F, 0, 15),
STONE(“STONE”, 1, 1, 131, 4F, 1, 5),
IRON(“IRON”, 2, 2, 250, 6F, 2, 14),
EMERALD(“EMERALD”, 3, 3, 1561, 8F, 3, 10),
GOLD(“GOLD”, 4, 0, 32, 12F, 0, 22);
delete the ; after the Gold line and put a comma there
for a new material
Namehere(“NAMEHERE”, 5, #, ##, #F, #, ###);
= 0 means it can only mine stone/coal, 1 means iron, 2 means gold/diamond/redstone/lupis, 3 means obsidian
= how many uses
#F = How strong it is against ores
= not sure XD put the same number as emerald (aka diamond)

How to give foods a potion effect
Open Me
Applying a potion effect to a food. This is very easy to do. You simply make a food(follow the tutorial above), and add this bit of code to it
.setPotionEffect(Potion.hunger.id, 30, 0, 0.8F)
so it would fit in like this:
public static final Item Namehere = new ItemFood(5001, 4, 1F, false).setPotionEffect(Potion.hunger.id, 30, 0, 1F).setItemName("anynamehere");
Note that .setPotionEffect MUST go before .setItemName otherwise you will get recompilation errors. I use the hunger potion in this example, which is what is used in rotten flesh. You can use any potion effect when doing this. They are all listed in Potion.java. I’m not sure what the 0 means, but the 30 is the time the effect lasts for. An int of 20 here lasts for 6 seconds, so 30 is about 9 seconds. The float(1F) is the chance of the potion being successful. Rotten flesh has 0.8F here, and it has an 80% chance of giving you food poisoning. Having 1F in this position should be a 100% success rate.[/details]
