"create a custom block with datapack and tell me where to loate everything"

In Minecraft Forge, you can create a custom block by extending the Block class and overriding necessary methods. You can then register the block in your mod's registry. Here is an example:

```java
/* Custom block class */
public class CustomBlock extends Block {
    public CustomBlock(AbstractBlock.Properties props) {
        super(props);
    }
}
```

You can then register this block in your mod's registry:

```java
public static final RegistryObject<Block> CUSTOM_BLOCK = BLOCKS.register("custom_block",
            () -> new CustomBlock(Block.Properties.copy(Blocks.DIRT)));
```

For the datapack, you need to create a new folder in the `data` directory of your mod's resources. This folder should be named after your mod's modid. Inside this folder, you can create the following directories: `blocks`, `items`, `recipes`, `loot_tables`, and `tags`.

For example, the location of the blockstate file for your custom block would be `src/main/resources/data/<your_modid>/blockstates/custom_block.json`.

The block model file would be located at `src/main/resources/data/<your_modid>/models/block/custom_block.json`.

The item model file (if your block has an item form) would be located at `src/main/resources/data/<your_modid>/models/item/custom_block.json`.

The loot table file would be at `src/main/resources/data/<your_modid>/loot_tables/blocks/custom_block.json`.

The recipe file would be at `src/main/resources/data/<your_modid>/recipes/custom_block.json`.

For tags, you can add your block to existing tags or create new ones. The tags are located in `src/main/resources/data/<your_modid>/tags/blocks` and `src/main/resources/data/<your_modid>/tags/items`.

Remember to replace `<your_modid>` with your mod's actual modid.

-- A custom projectile in Minecraft Forge is a new entity class that extends the ProjectileEntity class or any of its subclasses (e.g., ArrowEntity, SnowballEntity, etc.).
