[1.7.2]Function func_150297_b & generation

Hamster_Furtif · July 3, 2014

Hi everyone !

In my mod, I created a new flower, the cotton. You can use it to make an "armor" that you can dye later.

When I created the mod with MCP, it was very easy, I used the func_150297_b.

But now I use forge, It doesn't work.

So, here is my forge class, the func_150297_b are in red:

package com.hamsterfurtif.elisancecraft.armors;

import com.hamsterfurtif.elisancecraft.ElisanceCraftMOD;

import net.minecraft.client.renderer.texture.IIconRegister;
import net.minecraft.entity.Entity;
import net.minecraft.item.ItemArmor;
import net.minecraft.item.ItemStack;
import net.minecraft.nbt.NBTTagCompound;

@SuppressWarnings("unused")
public class ArmorCoton extends ItemArmor
{


private static final String[] Armor_Type = new String[] {"coton_helmet", "coton_chestplate", "coton_leggings", "coton_boots"};


 public ArmorCoton(ArmorMaterial armorMaterial, int renderIndex, int armourType) 
 {
		super(armorMaterial, renderIndex, armourType);

 }

 public String getArmorTexture(ItemStack stack, Entity entity, int slot, String layer)
 {
	 if (stack.getItem().equals(ElisanceCraftMOD.coton_helmet) || stack.getItem().equals(ElisanceCraftMOD.coton_chestplate) || stack.getItem().equals(ElisanceCraftMOD.coton_boots))
	 {
		 return "elisancecraft:textures/armors/coton_1.png";
	 }

	 if (stack.getItem().equals(ElisanceCraftMOD.coton_leggings))
	 {
		 return "elisancecraft:textures/armors/coton_2.png";
	 }

	 else
	 {
		 return null;
	 }

 }

 @Override
    public void registerIcons(IIconRegister reg)
    {
	 	if (this == ElisanceCraftMOD.coton_helmet)
	 	{
	 		this.itemIcon = reg.registerIcon("elisancecraft:coton_helmet");
	 	}
	 	if (this == ElisanceCraftMOD.coton_chestplate)
	 	{
	 		this.itemIcon = reg.registerIcon("elisancecraft:coton_chestplate");
	 	}
	 	if (this == ElisanceCraftMOD.coton_leggings)
	 	{
	 		this.itemIcon = reg.registerIcon("elisancecraft:coton_leggings");
	 	}
	 	if (this == ElisanceCraftMOD.coton_boots)
	 	{
	 		this.itemIcon = reg.registerIcon("elisancecraft:coton_boots");
	 	}
    }


public int getColor(ItemStack par1ItemStack)
    {
        if (this.getArmorMaterial() != ElisanceCraftMOD.enumArmorMaterialCoton )
        {
            return -1;
        }
        else
        {
        	if (this.getArmorMaterial() == ElisanceCraftMOD.enumArmorMaterialCoton)
        	{
        		NBTTagCompound var2 = par1ItemStack.getTagCompound();

        		if (var2 == null)
        		{
        			return 16777215;
        		}
        		else
        		{
        			NBTTagCompound var3 = var2.getCompoundTag("display");
        			return var3 == null ? 10511680 : (var3.[color=red]func_150297_b[/color]("color", 3)  ? var3.getInteger("color") : 16777215);
        		}
        	}
        	
        }



    }	

   public void func_82813_b(ItemStack par1ItemStack, int par2)
    {
        if (this.getArmorMaterial() != ItemArmor.ArmorMaterial.CLOTH && this.getArmorMaterial() != ElisanceCraftMOD.enumArmorMaterialCoton)
        {
            throw new UnsupportedOperationException("Can\'t dye non-leather!");
        }
        else
        {
            NBTTagCompound var3 = par1ItemStack.getTagCompound();

            if (var3 == null)
            {
                var3 = new NBTTagCompound();
                par1ItemStack.setTagCompound(var3);
            }

            NBTTagCompound var4 = var3.getCompoundTag("display");

            if (!var3.[color=red]func_150297_b[/color]("display", 10))
            {
                var3.setTag("display", var4);
            }

            var4.setInteger("color", par2);
        }
    }
}

My second question is about flower Generation. It's about the cotton flower. I would like it to spawn in savanna biomes only, and I searched a lot but found nothing, so, if someone could explain me how to do, it would be great .

func_150297_b is hasKey if that helps

Hamster_Furtif · July 3, 2014

Well, I used hasKey, but the function didn't work. It asked for a(nother) return statement at the end. What I a supposed to do ?

About the generation, here's all I've done:

package com.hamsterfurtif.elisancecraft.gen;

import java.util.Random;

import com.hamsterfurtif.elisancecraft.ElisanceCraftMOD;

import net.minecraft.world.World;
import net.minecraft.world.gen.feature.WorldGenerator;

public class WorldGenCoton extends WorldGenerator 
{
    private static final String __OBFID = "CL_00000189";

    public boolean generate(World par1World, Random par2Random, int par3, int par4, int par5)
    {
        for (int var6 = 0; var6 < 10; ++var6)
        {
            int var7 = par3 + par2Random.nextInt( - par2Random.nextInt(;
            int var8 = par4 + par2Random.nextInt(4) - par2Random.nextInt(4);
            int var9 = par5 + par2Random.nextInt( - par2Random.nextInt(;

            if (ElisanceCraftMOD.coton_sauvage.canPlaceBlockAt(par1World, var7, var8, var9))
            {
                par1World.setBlock(var7, var8, var9, ElisanceCraftMOD.coton_sauvage, 0, 2);
            }

        }

        return true;
    }
}

All the generation tutorials are about ores...

Hamster_Furtif · July 3, 2014

Well, I understood this :

If the armor is not made of cotton, then the function will return -1,

If the armor is made of cotton :

var2 equals the Armor's TagCoumpound (And to be honest, I don't really know what it means. I think it's if the armor is colored or not, and if it is, what color.)

If this Armor's TagCoumpound is null, th function will return the color 16777215.

Else,

var3 = var2.getCompoundTag("display");

and the function returns :

if var3 is null the function returns 10511680

if var3 isn't null AND var3.hasKey("color", 3) is true, the function returns var3.getInteger("color")

if var3 isn't null AND var3.hasKey("color", 3) if false, the function returns 16777215

Is all this right ?

Hamster_Furtif · July 3, 2014

Well, I suppose the method does not always return an int ?

And I guess It's because var3 isn't null, so the issue is in this part :

(var3.hasKey("color", 3)  ? var3.getInteger("color") : 16777215)

or in this one :

NBTTagCompound var3 = var2.getCompoundTag("display");

If it is in the first part, it's because

var3.hasKey("color", 3)

is not true, and then the function returns

var3.getInteger("color")

which is not an int.

So, the problem here is var3 ?

Hamster_Furtif · July 3, 2014

All the previous message was made to answer your question :

<<Do you actually know what the error message means ?>>

At the beginning of mine :

<<I suppose the method does not always return an int>>

Because I think that it want me to add a return statement to be sure the method will always return an Int.

And if it want to be sure that the method always return an int, it's because it currently doesn't. This is the point of my previous message.

If you're talking about the override thing, I just left it when I was doing a few test, that's all. I just suppressed it.

About var3 : I did not created all this, I copied it from the original code :

The vanilla version works very fine btw, so I don't know why I doesn't with Forge.

And this is where var3 comes from.

NBTTagCompound var3 = var2.getCompoundTag("display");

Hamster_Furtif · July 3, 2014

I suppressed the @Override.

Hamster_Furtif · July 3, 2014

I checked what @Override does, but what does it have to do with this method ? Should I override or not ?

And, what is wrong with my reasoning ?

Hamster_Furtif · July 3, 2014

Well, I think yes. I want to redefine superclass's method for my new class, so I have to Override. Isn't it the right thing to do ?

Hamster_Furtif · July 3, 2014

I want it to work not only with Leather but also with Cotton ! But it doesn't work, and I don't know why.

Hamster_Furtif · July 3, 2014

This is what I did, and it's not working !

Oh ! My mistake. So here's the exact code I used in vanilla, and it's working :

        	}

}

But the cotton is still not dyeable.

So, what should I do ?

Should I create a new class that extends RecipesArmorDyes ?

Or should I create a new class that implements IRecipie, and with the same content ?

One that extends RecipesArmorDyes... Less work..
