Updating your mod to 1.8

[sham1]

Could someone give me a quick crash course on how to make the JSONs to work. Where to place the textures ect. What about switching states such as having a model that changes one texture depending if the block is on or off. Ktnxbye.

Hi

 

You may find this link useful

http://greyminecraftcoder.blogspot.com.au/p/list-of-topics.html

Especially the topics under "Blocks" and "Items".

 

This example project also has several working examples of blocks and items with custom textures and with the switching states you said.

Hello and thanks for your guide!

 

I still have some troubles. First, I used metadata to differentiate between colors of my item (pipe), but that does not work now. I create recipes like this:

 

GameRegistry.addRecipe(new ItemStack(WaterPipe.waterpipe, 1, 0), new Object[] {" B ", " I ", "DGD", Character.valueOf('B'), Items.brick, Character.valueOf('I'), Items.iron_ingot, Character.valueOf('G'), Items.glass_bottle, Character.valueOf('D'), new ItemStack(Items.dye, 1, 2)});
GameRegistry.addRecipe(new ItemStack(WaterPipe.waterpipe, 1, 1), new Object[] {" B ", " I ", "DGD", Character.valueOf('B'), Items.brick, Character.valueOf('I'), Items.iron_ingot, Character.valueOf('G'), Items.glass_bottle, Character.valueOf('D'), new ItemStack(Items.dye, 1, 1)});
GameRegistry.addRecipe(new ItemStack(WaterPipe.waterpipe, 1, 2), new Object[] {" B ", " I ", "DGD", Character.valueOf('B'), Items.brick, Character.valueOf('I'), Items.iron_ingot, Character.valueOf('G'), Items.glass_bottle, Character.valueOf('D'), new ItemStack(Items.dye, 1, 4)});

 

But when I place this block and try to get it's metadata via getMetaFromState(state) in onBlockActivated, it always returns 0.

 

 

 

 

And second, I have trouble getting textures for metadata blocks. I played with it for some time, but without success.

 

public static final String[] multiBlockNames = { 
    	MODID + ":" + "greenWaterPipe", MODID + ":" + "redWaterPipe", MODID + ":" + "blueWaterPipe", MODID + ":" + "blackWaterPipe",
    	MODID + ":" + "limeWaterPipe", MODID + ":" + "orangeWaterPipe", MODID + ":" + "cyanWaterPipe", MODID + ":" + "pinkWaterPipe"
};


@EventHandler
    public void init(FMLInitializationEvent event)
    {
    	if(event.getSide() == Side.CLIENT)
	{
		RenderItem renderItem = Minecraft.getMinecraft().getRenderItem();
		for(int i = 0; i < 8; i++)
		{
			renderItem.getItemModelMesher().register(Item.getItemFromBlock(waterpipe), 0, new ModelResourceLocation(MODID + ":" + ((BlockWaterPipe) waterpipe).getName() + "_" + i, "inventory"));
		}
		ModelBakery.addVariantName(Item.getItemFromBlock(waterpipe), multiBlockNames);
	}
    }

 

And textures are in folder assets\reaper_waterpipe\textures\blocks

named WaterPipe_0, WaterPipe_1, WaterPipe_2 ...

 

Here is except from BlockWaterPipe

 

private final String name = "waterpipe";

    protected BlockWaterPipe ()
    {
        super(Material.glass);
        GameRegistry.registerBlock(this, WaterPipeMultiItemBlock.class, "waterpipe");
        setUnlocalizedName(WaterPipe.MODID + "_" + name);
        setHardness(0.3F);
        setResistance(5.0F);
        setStepSound(Block.soundTypeGlass);
        setCreativeTab(CreativeTabs.tabDecorations);
    }

 

My modid is "reaper_waterpipe"

 

Any help would be greatly appreciated

 

 

Okay, I fixed all problems thanks to TheGreyGhost's examples, thank you a lot

But I have one question - is it possible to render block in hand in the same way as block placed down, when it is set to render with specialRenderer? I.e. if I create new model and assign it to block via TileEntityRenderer, can I make it so the model is rendered when in hand, too?

Yes you can, have a look at ironchests as it has updated to 1.8 and has its chests are rendering in the inventory

[nokel81]

I am trying to figure this out. I have a .json file :

 

{
  "parent": "builtin/generated",
  "textures": {
    "layer0": "MinePlus:items/itemIronNugget"
  },
  "display": {
    "thirdperson": {
      "rotation": [ -90, 0, 0 ],
      "translation": [ 0, 1, -3 ],
      "scale": [ 0.55, 0.55, 0.55 ]
    },
    "firstperson": {
      "rotation": [ 0, -135, 25 ],
      "translation": [ 0, 4, 2 ],
      "scale": [ 1.7, 1.7, 1.7 ]
    }
  }
}

 

 

and I added your line to init()

 

Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(YourItem, 0, new ModelResourceLocation(ModInfo.MOD_ID + ":" + ItemNames.ironNugget, "inventory"));

 

what should I put in YourItem? and what should I call the texture.png file? Thanks

[61352151511]

"layer0": "MinePlus:items/itemIronNugget"

Surely your texture.png should be called itemIronNugget

 

YourItem should be an instance of your item. The same way you do GameRegistry.registerItem(YourItem, Name) to register your item

[nokel81]

And I put the itemIronIngot.png file in /MineCraftModding/forge-1.8-11.14.1.1321-src/src/main/resources/assets/MinePlus/textures/items/itemIronNugget.png

 

right?

[61352151511]

If for some reason your working directory is called "forge-1.8-11.14.1.1321-src" then yes, I don't know why it wouldn't be called something more accurate like "MinePlus" but that's your decision. Yes that is the correct path to put the file in.

I'm trying to figure out how to use custom armor textures in 1.8.  Does anyone know how to do it in 1.8? I misunderstood my own code. I thought that setTextureName() sets armor texture name instead of item texture name.

[Ferrettomato]

I've been trying to learn Forge recently with the help of Wuppy29's book, but since that was written for 1.7.10, I've had to refer to this thread many times. I've been trying to register the JSON files for a block. The OP says that the following line can be used for both blocks and items:

Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(YourItem, metadata, new ModelResourceLocation("modid:items_registered_name", "inventory"));

But that method only works if the first parameter is an Item object. What am I supposed to do differently to register block models?

[CoderAtParadise]

YourItem when dealing with blocks becomes

Item.getItemFromBlock(YourBlock)

[Ferrettomato]

That worked, thanks!

ModelBakery.addVariantName(yourItem, new String[]{"different", "variant", "namesOfModelFiles"});

 

Im not the smartest, so im just trying to clarify something. but for this part of the code you input your .json file locations, correct? So you might replace "different" with "ModID:Cobblestone.json" and "variant" with "ModID:Cobblestone_mossy.json". I just want to make sure so im not missing anything.

The strings passed to

ModelBakery.addVariantName

are the names of the item models (without extensions) to load. If you pass the string

"ModID:Cobblestone"

, it will load the model file assets/modid/model/item/Cobblestone.json.

 

Side note: You don't need to explicitly create an array when calling vararg methods like

ModelBakery.addVariantName

. Simply pass the values and Java will create an array for you (this is the whole point of vararg methods).
