unity-3d-math

What problem does it solve?

This Skill addresses common and subtle errors in Unity's 3D math operations, ensuring your game logic is precise and avoids hard-to-debug issues related to coordinate spaces, rotations, and floating-point comparisons.

Core Features & Use Cases

• Coordinate Space Correctness: Differentiates between TransformPoint, TransformDirection, and TransformVector.
• Quaternion Safety: Prevents gimbal lock and direct component modification errors.
• Floating-Point Precision: Guides on using Mathf.Approximately and sqrMagnitude for reliable comparisons.
• Use Case: Prevent a character from rotating incorrectly due to gimbal lock by ensuring all rotations are interpolated using Quaternion.Slerp instead of Euler angles.

Quick Start

Use the unity-3d-math skill to correct the quaternion multiplication order when combining rotations.
