O3DECon 2021

Esteban will walk the audience through how to build the engine and a default game. Esteban will cover different options the engine can be configured with. He will also go over different workflows available to build the game. This workshop is aimed at an audience that wants to get started on the Engine to either contribute to the engine or start building a game. This workshop will not dive deeply into the technical, but instead will be introductory and practical. For a deeper presentation on the internals of the build system, consider the "O3DE Build System" Session.

A birds' eye view of the systems that make up the O3DE Editor. This talk provides an overview of the underlying systems and frameworks that power the Open 3D Engine Editor, including the structure of its code, its usage of the Qt Widgets library for UI, and its integration with the O3DE component entity framework and Atom renderer.

Editor Extension - Is there a tool in the Editor that is missing what you need, or have you always wanted to build your own tool from scratch? This talk will teach you how to create your own custom tool in both C++ or Python. Once you learn the necessary APIs for communicating with the Editor, you will only be limited by your imagination.

For a general overview of the Editor, please consider attending the Editor 101 Workshop.

Sourcegraph has indexed over 2M open source repositories and counting to bring code search to the open source universe and code literacy to a much wider audience. By using Sourcegraph, developers can search, understand, and automate throughout their codebases. We will show you how you can improve your developer experience and optimize workflows as you contribute to the O3DE project; using Sourcegraph features like code search, code intelligence (go to definition; find reference), batch changes, IDE integrations, and more. By the end of this workshop, you’ll be able to use Sourcegraph to help you increase code reuse, improve code reviews, and understand who and what is being contributed to the O3DE project.

In this workshop Luis Sempé provides an introduction to game development using Script Canvas, the visual scripting solution in O3DE. He will provide some background around the event-driven and entity/component nature of O3DE, he will guide you through a few introductory game systems and discuss common patterns and pitfalls.

Input is what differentiates interactive experiences from all other entertainment mediums. Regardless of genre or platform, every game is driven by some form of player interaction with a physical input device. But there are many different types of input devices, each of which can produce a wide range of input data, and the way this data is delivered to an application is rarely consistent across devices or platforms. As a cross platform game engine, we want to provide platform independent access to input data from any supported device, using a common interface that should be:
- Platform/device agnostic
- Extensible
- Efficient

In addition, input data should be:
- Obtainable by subscribing to receive events that are dispatched whenever an input device emits new data.
- Obtainable by polling the current state / value of an input device at any time.
- Able to support custom data payloads that add no overhead unless used.

Lastly, most games require support for one or more of the following:
- Input mapping, so that different types of input devices can be used to produce the same in-game actions (eg. keyboard space bar or gamepad A -> "Jump").
- Input contexts, so that different sets of input mappings are active depending on the in-game context (eg. running around vs driving a car vs flying a plane).
- Local user identification, so that different users can interact with the game at the same time (eg. local multiplayer, either co-op or versus).

In this talk, we will take a moment to navigate the open-source world through the Open 3D Engine project. We will talk about special interest groups, getting involved, finding help, working with the community, advancing ideas, and features in a distributed decision environment.
