# Contains() Methods

v4.0

{% hint style="info" %}
Example code here is from `GameStatList.cs`, though similar methods are on other list classes as well.

Methods for specific list types are below.
{% endhint %}

{% hint style="info" %}
The common methods can be found in `GameModuleListExtensions.cs`
{% endhint %}

## `Contains()`

You can also get a `bool` if a list contains a specific object, or object by gameId, or even if the list contains an `objectType`.

{% hint style="info" %}
Remember, the `objectType` of a Game Module object is the name of the folder the Scriptable Object is in.
{% endhint %}

```csharp
if (gameStatList.Contains(Stat)) // Pass in a Scriptable Object type
    DoSomething();
    
if (gameStatList.Contains(GameStat)) // Pass in a Game Module Object type
    DoSomething();
    
if (gameStatList.Contains(uid)) // Pass in the Uid of the Object
    DoSomething();
    
if (gameStatList.ContainsGameId(gameId)) // Pass in the run-time GameId of the object
    DoSomething();
    
if (gameStatList.ContainsObjectType(objectType))
    DoSomething();
    
if (gameStatList.ContainsName(objectName))
    DoSomething();
    
if (gameStatList.ContainsDuplicates()) // Checks for duplicates of any uid
    DoSomething();
    
if (gameStatList.ContainsDuplicates(uid)) // Only checks for duplicates of this uid
    DoSomething();
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://infinitypbr.gitbook.io/magic-pig-games/game-modules-4/module-documentation/game-module-lists/contains-methods.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
