# Unity 3D applications

Unity 3D is an integrated cross-platform game engine that is used to build interactive 3D games, animations, visualizations, 3D models, etc.

Generally speaking, blockchain platform integration is carried out after the game clears it's development phase. Ontology provides two swift methods of integrating blockchain technology in Unity based games: `dAPI`, and `SDK` based integration.

* Integrating `dAPI` using the `Cyano` wallet Chrome plugin. These games must be compiled and rendered using `Web GL`. Here's a demo for web based games: <https://github.com/ontio-community/unity-dapi-demo>
* Integrating `dAPI` via the PC version of the wallet. The game must be PC compatible to be able to implement this method of integration.
* Integrating `dAPI` using the `C# SDK`. This method can be used for games that are mobile based, as well as other platforms. Demo code: <https://github.com/ontio-community/unity-demo>

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ont.io/guides-and-tutorials/integration-guides/dapps/unity-3d.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
