## Reference

### NodeTypeName

Gets the type name for this text processor node.
Returns "TextProcessorNode" to identify this as a text processing node type.

#### Returns

**Type:** `string`

***

### NeedRemoveTextInBrackets

Gets or sets whether to remove text enclosed in brackets from the input.
When enabled, content within `[]`, `()`, `{}` brackets will be filtered out.

#### Returns

**Type:** `bool`

***

### NeedRemoveSubstring

Gets or sets whether to remove specified substrings from the input.
When enabled, strings listed in substringsToRemove will be filtered out.

#### Returns

**Type:** `bool`

***

### NeedRemovePlayerName

Gets or sets whether to remove the player name from the input text.
When enabled, the current player name will be added to the removal list.

#### Returns

**Type:** `bool`

***

### NeedRemoveSentenceStream

Gets or sets whether to process the input as sentence streams.
When enabled, text will be broken down into individual sentences for processing.

#### Returns

**Type:** `bool`

***

### NeedRemoveEmojis

Gets or sets whether to remove emoji characters from the input text.
When enabled, all emoji symbols will be filtered out from the text.

#### Returns

**Type:** `bool`

***

### SubstringsToRemove

Gets or sets the list of specific substrings to remove from the input text.
Contains custom strings that should be filtered out during text processing.

#### Returns

**Type:** `List<string>`

***

### ProcessBaseData

Processes the input data through various text filtering and cleaning operations.
Applies the configured text processing operations in sequence based on the enabled options.

```csharp theme={"system"}
protected override InworldBaseData ProcessBaseData(InworldVector<InworldBaseData> inputs)
```

#### Parameters

| Parameter | Type                             | Description                         |
| --------- | -------------------------------- | ----------------------------------- |
| inputs    | `InworldVector<InworldBaseData>` | The vector of input data to process |

#### Returns

**Type:** `InworldBaseData` - The processed text data as an InworldDataStream, or an error if processing fails

***

## Serialized Fields

The following fields are configurable in the Unity Inspector:

* **needRemoveTextInBrackets** (`bool`) - Whether to remove text enclosed in brackets (default: true)
* **needRemoveSubstring** (`bool`) - Whether to remove specified substrings (default: true)
* **needRemovePlayerName** (`bool`) - Whether to remove the player name (default: true)
* **needRemoveSentenceStream** (`bool`) - Whether to process as sentence streams (default: true)
* **needRemoveEmojis** (`bool`) - Whether to remove emoji characters (default: true)
* **substringsToRemove** (`List<string>`) - List of specific substrings to remove

## Important Notes

### Text Processing Operations

* **Bracket Removal**: Filters out content within `[]`, `()`, `{}` brackets
* **Substring Filtering**: Removes custom strings and optionally the player name
* **Sentence Streaming**: Breaks text into individual sentences for processing
* **Emoji Removal**: Filters out all emoji symbols from text
* **Sequential Processing**: Operations are applied in order based on enabled options

### Configuration

* **Default Settings**: All processing options are enabled by default
* **Custom Substrings**: Use `substringsToRemove` list for additional filtering
* **Player Name Integration**: Automatically adds player name to removal list when enabled
* **Error Handling**: Returns appropriate error data if input validation fails
