Setting Up Your Rec Room AI Environment

Preparing the Game Map

Before we dive into the nitty-gritty of AI circuits, let's set the stage. Start by cloning your existing Game map. This clone will be the playground for your AI, allowing you to craft a rich, layered experience. Imagine it as building a secret underground world for your AI to roam, while your human players enjoy the main stage above.

Make sure there's ample space between the original and cloned maps. The more distance, the better, to avoid any audio or visual crossover. You don't want your players hearing AI sound effects from below or accidentally triggering AI actions.

Key Considerations for Map Preparation:

• Vertical Separation: Keep a good vertical distance to avoid audio bleed and prevent accidental AI activation.
• Map Coverage: Ensure the cloned map covers the entire playable area of the original map, allowing AI to navigate freely.
• Wall Integration: Clone the walls as well, using your maker pen. This keeps your AI characters within bounds and adds to the realism of your world.

Baking the NavMesh for AI Navigation

The NavMesh is like a roadmap for your AI, telling it where it can go. With your map cloned, it's time to bake this essential navigation tool.

Here's how to bake the NavMesh:

1. Open the Room Settings menu.
2. Head to the AI tab.
3. Hit the Bake NavMesh button. Once done, a translucent white box will appear around your cloned map, indicating the AI's navigable area.

If you've moved or changed the AI's NavMesh, you might see purple areas on the map, marking new pathing zones. Remember, if you adjust the clone while baking, don't forget to clone the walls too, or your AI might take an unexpected dive off the map!

After baking, you may need to adjust the NavMesh to ensure your AI can explore the entire map. Use the "Manipulate" tool in your maker pen to expand the NavMesh to cover new areas. Don't forget to rebake after changes to make them stick.

Troubleshooting NavMesh Issues:

• NavMesh Not Appearing: Double-check that your cloned map is correctly aligned within the room's boundaries.
• AI Stuck in Place: Refine the NavMesh by adding or removing obstacles, and ensure the "Show in room" box is checked in settings.

AI Components and Circuitry in Rec Room

Spawning the Rec Room AI: The Spawner Component

The Spawner Component is your gateway to bringing AI characters into your game world. It controls where, when, and how your AI appears, adding a dynamic flair to your Rec Room experiences.

Key Steps to Spawning AI with Spawner Component:

1. Enable Beta Content in Room Settings to access the Spawner Component.
2. Add the Spawner Component to your cloned map where you want your AI to appear.
3. Configure the Spawner using your Maker Pen, setting the object to spawn and choosing "disengaged" behavior for non-aggressive spawns.
4. Select an AI type like Melee Goblin or Mouse Bot, depending on your desired AI behavior.
5. Detach the Spawner Component and move it to the AI circuitry area for easier manipulation.

Don't forget to tag your AI for easy circuit manipulation later. This helps with pathing and navigation.

Building the AI Circuitry: Core Components

The real magic happens with Rec Room's circuitry. By connecting various components, you can control your AI's behavior, movement, and interactions. It might seem complex, but breaking it down makes it manageable.

Essential Circuit Components for AI Behavior:

• Event Receiver: Triggers actions based on game events, set to "Update 30Hz" for smooth AI updates.
• Rec Room Object Get All With Tag: Identifies AI objects by tags, making them easy to manipulate.
• Is Valid: Checks if an object exists before further operations, avoiding errors.
• Rec Room Object Get First With Tag: Finds the first object with a specified tag.
• From Rec Room Object: Retrieves data from objects, converting it for use in other circuits.
• Vector3 Split & Create: Manages position data, crucial for AI movement.
• Add: Adjusts coordinates, like the Y-axis for AI positioning.
• Lerp: Ensures smooth transitions in character movement.
• Set Transform: Positions and rotates AI objects.
• Get Position: Reads an object's world position.
• Raycast: Detects objects in a line, useful for player detection.
• Get Closest: Identifies the nearest player.
• Subtract: Used in vector calculations for navigation.

To smooth out AI rotations and prevent jittering, add a Lerp to your circuit. It's a simple yet effective way to ensure your AI moves naturally.

Integrating Key Components for AI Success

Linking Objects for Dynamic AI Movement

Want your AI to move in interesting ways? It's all about connecting the right components. Trigger volumes, Rec Room objects, Vector3s, AI paths, and Event Receivers are your building blocks.

Step 1: Trigger Volume Connections

Start by connecting the trigger volume to your AI's animation controller or monster. This connection will animate your AI when a player enters the trigger volume, whether it's a monster roaring or an AI character speaking.

Step 2: Building AI Patrol Points

Connect an AI path to your AI, establishing patrol points for them to follow when no players are around.

Place these points logically within your map, ensuring they're within the playable area for effective patrolling.

Smooth Movement and Following Techniques

To take your AI's movement to the next level, clone your Vector3 Split and follow these steps:

• Place the clone above the set transforms.
• Connect the velocity to the Vector3 Split, ensuring smooth chasing movements.

Create additional components like "From Rec Room Object," a boolean, and an "if" chip to enhance your AI's responsiveness and interaction.

Enabling Room Authority for AI Spawning

To ensure everyone can enjoy your AI characters, enable room authority for AI spawning. Use an event definition and ensure beta content is enabled in settings. This setup allows AI to spawn smoothly and interact with players as intended.

Creating a Basic Line of Sight (LOS) AI Character

A good line of sight is crucial for your AI to effectively interact with players. Use a trigger and raycast to establish this connection, ensuring your AI can see and respond to players in its environment.
