I'm trying to make my first mod, which adds explosive arrows, similar to what Notch does in this video:

I know Java and Eclipse well enough, I just don't know Forge's API. I'm using Forge 1.15.2. If someone could point out the steps that I need to take in my code to accomplish this, as well as give me a rough idea of how I should go about it, that would be awesome. To be clear, I'm not overriding what arrows already do. I want to add a new type of arrow, with its own crafting recipe, texture, and name.

I'd start with the TippedArrow class, and ArrowEntity class.

Yeah, I figured that much out.

For the moment I currently have a generic item with the arrow's texture named "Explosive Arrow", and a class that extends the ArrowEntity class. I suppose what I want to do is figure out how to connect the two so I can shoot my arrow like a normal arrow, then add explosions in later.

Do you have createArrow() in your ArrowItem class? It should reference your arrow entity in there.

I didn't make a class for my item. Here's my definition in code:

public static final Item explosive_arrow = 
			new Item(new Item.Properties().group(ItemGroup.COMBAT))
			.setRegistryName(new ResourceLocation(ModProps.MOD_ID, "explosive_arrow"));

I suppose I should make a class that extends Item, shouldn't I?

Edit: I've made a class that extends ArrowItem, and overrode the createArrow method, but I still can't fire my arrow in survival mode. Do I need to register my explosive arrow as an entity?

In ArrowItem#createArrow:

public AbstractArrowEntity createArrow(World worldIn, ItemStack stack, LivingEntity shooter)
 {
      ArrowEntity arrowentity = new ArrowEntity(worldIn, shooter);
      arrowentity.setPotionEffect(stack);
      return arrowentity;
   }

Use your arrow Entity instead.

I've already been doing that, it's still not working.
