I have a mod where a pickaxe changes its textures between night and day. It worked in 1.8 but I am converting it to 1.10. The old methods don't work and I currently am trying to find a way to do so.

 

This was the code responsible for doing this in 1.8.

@Override
public void onUpdate(ItemStack item, World world, Entity player, int num, boolean bool) {
if (world.getWorldTime() % 24000 < 12000) {
dayTime = true;
}
else {
dayTime = false;
}
}

@Override
public ModelResourceLocation getModel(ItemStack stack, EntityPlayer player, int usesLeft) {
if (dayTime)
  return new ModelResourceLocation(MyMod.MODID + "myPickaxe", "inventory");
else
  return new ModelResourceLocation(MyMod.MODID + "myPickaxe2", "inventory");
}

 

Here is my first try at it.

public CustomPickaxe() {
	super(MyMod.myToolMaterial);
	this.setCreativeTab(CreativeTabs.COMBAT);
	this.setUnlocalizedName("myPickaxe");

	this.addPropertyOverride(new ResourceLocation(MyMod.MODID,"dayTime"), new IItemPropertyGetter()
	{
        @SideOnly(Side.CLIENT)
        public float apply(ItemStack stack, @Nullable World worldIn, @Nullable EntityLivingBase entityIn)
        {
        	if(entityIn == null){
        		return 0.0F;
        	}
        	if(worldIn == null){
        		worldIn = entityIn.worldObj;
        	}
  
        	if (PickaxeHelper.isDayTime(worldIn)) {
        			return 0.0F;
        		}else {
        			return 1.0F;
        		}
        }
	});

}




}

And the model file is.

{
    "parent": "item/handheld",
    "textures": {
        "layer0": "fundamentals:items/myPickaxe"
    },
    "overrides": [
        {
            "predicate": {
                "dayTime": 0
            },
            "model": "fundamentals:item/myPickaxe"
        },
        {
            "predicate": {
                "dayTime": 1
            },
            "model": "fundamentals:item/myPickaxe2"
        }
    ]
}

 

 

 

 

{
    "parent": "item/handheld",
    "textures": {
        "layer0": "fundamentals:items/myPickaxe"
    },
    "overrides": [
        {
            "predicate": {
                "fundamentals:dayTime": 0
            },
            "model": "fundamentals:item/myPickaxe"
        },
        {
            "predicate": {
                "fundamentals:dayTime": 1
            },
            "model": "fundamentals:item/myPickaxe2"
        }
    ]
}

Still getting a purple block.  Maybe I am not registering the textures right?

 

Located in Init() in MyMod.java

ModelBakery.registerItemVariants(myPickaxe, PickaxeHelper.getModel("myPickaxe"), PickaxeHelper.getModel("myPickaxe2"));

 

GetModel's declaration.

public static ModelResourceLocation getModel(String name) {
	return new ModelResourceLocation(MyMod.MODID + ":"+name, "inventory");
}

 

 

Well, I ended up figuring it out.

 

Thank you for your help, especially with the predicate.
