In this video, I’m working on my dice roller app project by creating the animated roll mechanic. 🎲
I’ll show you how I:
✅ Created the dice roll animations
✅ Set up the Unity Animator to control them
✅ Creating a blend tree
✅ Got everything working together for a smooth roll effect

The Main Issues:
1. Gimbal Lock
This occurs when using Euler angles (the X, Y, Z rotation values you see in the inspector). When one axis reaches ±90 degrees, you lose a degree of freedom and rotations can become unpredictable or take unexpected paths.
2. Quaternion Flipping/Quaternion Ambiguity
Quaternions can represent the same rotation in two ways (q and -q both represent the same rotation). When Unity interpolates between rotations, it might choose the « wrong » quaternion representation, causing the rotation to take the long way around (Greater than 180 degrees instead of the shorter path).
3. Euler Angle Interpolation Problems
When you animate or lerp Euler angles directly, Unity treats each axis independently. This causes issues like:
Rotating 350° to 10° goes the long way (through 340° of rotation) instead of the short way (20°)
Unpredictable rotation paths when multiple axes change simultaneously
This is a big step toward making the dice roller feel polished and fun to use. Follow along if you’re into Unity projects, animation setup, or game dev tutorials!
