The item I want to add is my potatoseed and I tried it with melonseed too and it gaves me the same error. The Error appears when im hitting grass and if i would become the seed

it crashs.

I don't know how to fix it and im new on Forge modding.

I hope somebody can help me,

Bye

 

Ps: Sry for my bad English, i hope you can excuse me.

Remember to +256 your item id, Or, more properly: item.itemID is the value you should use.

I cant use item.ItemID it says its not applicabel for Item int int int

and it gives me no error with MinecraftForge.addGrassSeed(1015, 0, 1, 20);

only if i hit grass Minecraft crashs I think I have to add a render for my seed or something like that but

no idea how to do this

Your item.itemID, that is a number, not a item, and it should work fine.

The problem is your item id is not a valid ID hence the null pointer.

Pass in a proper value {using one of the methods I described before}

It's working fine with vanilla items+blocks but if i try using my custom seeds+bloocks+items etc. it crashs with the error above

-.-

Full code or gtfo.

Item Etc:

 

public class mod_Food extends BaseMod

{

public static final Item PotatoSeed = new ItemSeedsTextureHandler(386, mod_Food.Potato.blockID, Block.tilledField.blockID).setItemName("PotatoSeed").setIconIndex(;

 

static {

ModLoader.addName(PotatoSeed, "Potato Seed");

 

public String getVersion()

{

return "1.2.5";}

 

public void load() {

MinecraftForge.addGrassSeed(386,0,1,10);

}

 

 

} }

 

 

ItemSeedsTextureHandler:

 

 

package net.minecraft.src;

 

import net.minecraft.src.forge.ITextureProvider;

 

public class ItemSeedsTextureHandler extends ItemSeeds implements ITextureProvider

 

{

  public ItemSeedsTextureHandler (int par1, int par2, int par3) {

  super(par1,par2,par3);

  }

public String getTextureFile()

    {

            return "/FoodMod/gui/items.png";

    }

 

 

{

 

}

}

 

Item Etc:

 

public class mod_Food extends BaseMod

{

public static final Item PotatoSeed = new ItemSeedsTextureHandler(386, mod_Food.Potato.blockID, Block.tilledField.blockID).setItemName("PotatoSeed").setIconIndex(;

 

static {

ModLoader.addName(PotatoSeed, "Potato Seed");

 

public String getVersion()

{

return "1.2.5";}

 

public void load() {

MinecraftForge.addGrassSeed(386,0,1,10);

}

 

 

} }

 

 

ItemSeedsTextureHandler:

 

 

package net.minecraft.src;

 

import net.minecraft.src.forge.ITextureProvider;

 

public class ItemSeedsTextureHandler extends ItemSeeds implements ITextureProvider

 

{

  public ItemSeedsTextureHandler (int par1, int par2, int par3) {

  super(par1,par2,par3);

  }

public String getTextureFile()

    {

            return "/FoodMod/gui/items.png";

    }

 

 

{

 

}

}

 

 

For note, you completely ignored what Lex stated, look at this:

MinecraftForge.addGrassSeed(386,0,1,10);

So you use the shifted itemID of 386, however your item uses this:

public static final Item PotatoSeed = new ItemSeedsTextureHandler(386, mod_Food.Potato.blockID, Block.tilledField.blockID)./*snip*/;

Which is a *non*shifted itemID of 386.

 

As Lex said, you need to use the shifted itemID, either of these will work:

MinecraftForge.addGrassSeed(PotatoSeed.itemID,0,1,10);

MinecraftForge.addGrassSeed(386+256,0,1,10);

 

Remember, Minecraft is stupid with itemIDs, you need to take the stupidity in to account.

Item Etc:

 

public class mod_Food extends BaseMod //if you plan to make it smp change BaseMod to NetworkMod

{

public static final Item PotatoSeed = new ItemSeedsTextureHandler(386, mod_Food.Potato.blockID, Block.tilledField.blockID).setItemName("PotatoSeed").setIconIndex(;

 

static {

ModLoader.addName(PotatoSeed, "Potato Seed");

MinecraftForge.addGrassSeed(386,0,1,10);
