# TagManagerBlock

## Importing the class

It might be required for you to import the package if you encounter any issues (like casting an Array), so better be safe than sorry and add the import at the very top of the file.
```zenscript
import crafttweaker.api.tag.TagManagerBlock;
```


## Implemented Interfaces
TagManagerBlock implements the following interfaces. That means all methods defined in these interfaces are also available in TagManagerBlock

- [ITagManager](/vanilla/api/tag/ITagManager)&lt;[Block](/vanilla/api/block/Block)&gt;

## Methods

:::group{name=exists}

Checks if a tag already exists. Does the same as calling `.exists` on a tag directly

Returns: Whether this tag already exists  
Return Type: boolean

```zenscript
TagManagerBlock.exists(location as ResourceLocation) as boolean
```

| Parameter    | Type                                                       | Description                        |
| ------------ | ---------------------------------------------------------- | ---------------------------------- |
| Localisation | [ResourceLocation](/vanilla/api/resource/ResourceLocation) | The resource location to check for |


:::

:::group{name=exists}

Checks if a tag already exists. Does the same as calling `.exists` on a tag directly

Returns: Whether or not this tag already exists  
Return Type: boolean

```zenscript
TagManagerBlock.exists(name as string) as boolean
```

| Parameter | Type   | Description                        |

:::

:::group{name=getAllTags}

Retrieves a list of all tags currently registered.

Return Type: stdlib.List&lt;[MCTag](/vanilla/api/tag/MCTag)&lt;T&gt;&gt;

```zenscript
// TagManagerBlock.getAllTags() as stdlib.List<MCTag<T>>

myTagManagerBlock.getAllTags();
```

:::

:::group{name=getTag}

Retrieves a tag by its name. Will also be called by the BEP.

 Note that this method does _not_ yet create the tag if it does not exist. Adding something to the object created by this tag will create it for the game.

Returns: A Tag object.  
Return Type: [MCTag](/vanilla/api/tag/MCTag)&lt;T&gt;

```zenscript
TagManagerBlock.getTag(location as ResourceLocation) as MCTag<T>
```
