Version Number confusion

[TheAncientMinecrafter]

Hi

 

I'm new to modding. I've got Eclipse installed (under Ubuntu 12.10) and I've got ForgeGradle loaded but I'm getting errors when I try to extend the EntityCow class. I think the problem is that Forge is running 1.7 but I've only been able to find the MCP source code for 1.6 and I think that's causing all sorts of conflicts. Also I need to figure out how to refactor the entire project so it's out from under Minecraft. But with ForgeGradle I'm finding it hard to see where the Minecraft code is hiding.

 

Here's the latest error code:

And here's the code as it stands at the moment. (I know it'll never work like this - I'm just commenting everything out and adding it in one bit at a time until I get a crash!)

 

 

package com.example.examplemod;

public class ExampleMod extends EntityCow

{

  public ExampleMod(World par1World) {

super(par1World);

// TODO Auto-generated constructor stub

}

 

public static final String MODID = "examplemod";

    public static final String VERSION = "1.0";

   

    @EventHandler

    public void preinit(FMLPreInitializationEvent event)

    {

    GameRegistry.addRecipe(new ItemStack(Items.apple, 4), new Object[]{

    "AA",

    "AA",

    'A', Blocks.cobblestone

    });

    }

   

    @EventHandler

    public void init(FMLInitializationEvent event)

    {

    protected void dropFewItems(boolean par1, int par2)

    {

        int var3 = this.rand.nextInt(3) + this.rand.nextInt(1 + par2);

        int var4;

 

        for (var4 = 0; var4 < var3; ++var4)

        {

            }

            else

            {

                this.dropItem(Items.beef, 1);

            }

        }

            this.dropItem(Items.bone, 1);

    }

*/

}

 

 

 

I'm tempted to just bin everything, delete or move the directories and start a fresh build. But I won't do that until I can be confident I'm all on the same version for everything!

 

thanks

@Mod(modid = ExampleMod.MODID, version = ExampleMod.VERSION)
public class ExampleMod extends EntityCow
{

 

WTF???

[TheAncientMinecrafter]

I was trying to change some of the attributes of EntityCow so I thought I'd extend it. Have I forgotten that much java?

 

 

[larsgerrits]

You did it totally wrong. You should be reading it as: My mod is a cow!

[GotoLink]

But with ForgeGradle I'm finding it hard to see where the Minecraft code is hiding.

External librairies.

Doesn't look like you searched before asking.

[sequituri]

Once when I was a noob to modding and I hadn't yet read any tutorials, I wondered what the base class for a mod should be, too. However, I never in my wildest dreams imagined it would extend EntityCow! That is pretty novel.

[TheAncientMinecrafter]

OK - I used to be a Java programmer in Life-Before-Children so I can remember how to code. I have read many, many modding tutorials, read and searched the forums and had a scan through the Javadoc. My plan was to create a new Cow mob that had slightly different behaviour, so I thought I'd try extending EntityCow so my new mob would be like a Cow. I know the code doesn't look like the code for a mob, that's because it crashed so I thought I'd add in a small bit of code each time and see where it crashed.

 

If this is really hopelessly naive could you manage to point me in the right direction rather than just commenting on how silly it all is? And yes, I am very rusty, where the *** do you find external libraries? I'm still concerned that my version numbers are out of synch between Forge and the Minecraft code.

 

Graham

[larsgerrits]

It's in the Minecraft project, you should see it as 'Referenced Libraries' and then the first one in the list: 'forgeSrc-*******'.

[GotoLink]

Extending EntityCow isn't bad...but using @Mod this way is kinda strange. You might want to read its javadoc.

[TheAncientMinecrafter]

Thanks guys, I've made huge amounts of progress. And I think I've just figured out that I should have one mod file to load all the modified mobs which will be in their own class files. Which means that the @mod will only show up in one file that doesn't extend anything.

 

Off to take a break before I attempt that.

 

Cheers!
