SensorToolkit 2 – Free Download

SensorToolkit is a collection of ‘sensor’ components that detect objects and sense the world around them. It elegantly manages the complexities of object detection so you can focus on the fun stuff.

“Sharing is caring”

SensorToolkit is a powerful abstraction over the built-in Unity functions like Raycasts, Overlaps and Trigger Colliders. Each sensor is a standalone component that you can put on your GameObjects and configure. They can be queried for what they detect, and provide additional information such as a targets visibility or shape.

Documentation

Upgrading from v1

Discord

Features:

• Works in 2D and 3D.

• Many sensor types: Raycasting, Volumetric, Steering, Line of Sight and more.

• Lightweight and modular. Sensors are independent components that feel native to Unity.

• Easy to integrate with your project. Add a sensor component, configure it and you’re done.

• Unopinionated and flexible, design your game however you want.

• Many filtering options and querying functions for fine-tuning what to detect.

• Detect individual colliders or rigid bodies composed of multiple colliders.

• Advanced line-of-sight implementation can calculate partial visibility.

• Test sensors in the editor and confirm their configurations before running the game.

• Upgraded steering behaviour based on ‘Context-Based Steering’ method.

• Zero garbage generated.

Who is this for:

SensorToolkit is designed for all users, regardless of how you use Unity it’s built to make your life easier. Non-programmers will love SensorToolkit because you can compose complex detection behaviour without writing a line of code. The kit is integrated with Playmaker and there are more integrations on the way. Programmers will love SensorToolkit because it’s a powerful foundation on which to build AI behaviours. It will manage the complexities of object-detection and provide you a clean and simple interface. Furthermore the widgets and debugging inspectors will help you find configuration issues quickly. You’ll reduce boilerplate, and keep your scripts lean and neat.

Integrations:

– Playmaker

– Behavior Designer

Difference from v1:

This is a significant update from v1 of SensorToolkit. The basic structure is the same, but it’s reformulated to greatly increase its flexibility. Almost all of the code has been rewritten based on feedback I’ve received and my experience using it over the last 4 years.
