In-World Arcade: Pre-made Characters

In the In-World Arcade, developers can find a collection of pre-made characters created by the community. These characters come with different personalities and informational topics, providing developers with a diverse pool of characters to choose from. These pre-made characters can be interacted with and serve as a great starting point for developers in their game development journey.

Through a simple interface, developers can bring their characters to life and give them unique attributes and qualities.

Exploring the In-World Workspace

The In-World Workspace is where developers can organize and manage their characters. It provides a central hub for creating and assigning characters to specific scenes within the game. By assigning characters to different scenes, developers can create complex interactions and dynamic conversations between characters. The common knowledge pool further enhances the dialogue options, allowing characters to have a broader range of topics to discuss and making them more engaging for players.

Once the integration is complete, developers can test their characters within the Unreal Engine environment. They can interact with the characters, initiate conversations, and observe how the characters respond. This testing phase allows developers to fine-tune the character's behaviors, dialogue options, and overall performance within the game. In-World provides a range of examples and templates to help developers get started and explore the full potential of their characters.
