Barrel Animation — Unity Physics Sandbox

A small Unity project demonstrating a physics-driven rolling barrel: a Rigidbody game asset that the player drives with force and torque, paired with a custom low-poly collision mesh. Built as a focused exercise in the Blender → Unity game-asset pipeline and in Unity's rigidbody physics.

• Engine: Unity 2022.3.49f1 (LTS), built-in render pipeline
• Language: C#
• Source art: Blender (modelling, UV unwrap, albedo texture bake)

RollingObject (Assets/scr/NewBehaviourScript.cs) reads the Horizontal and Vertical input axes and drives the barrel through physics rather than transform manipulation:

• AddForce applies translational movement in the input direction.
• AddTorque applies rotation on the perpendicular axis, so the barrel visually rolls in the direction it travels instead of sliding.

Both moveSpeed and rotationSpeed are serialized fields, tunable in the Inspector without recompiling.

The barrel ships as two meshes, which is the point of the exercise:

Using the render mesh directly as a collider is expensive and, because Unity requires convex mesh colliders for moving rigidbodies, unreliable. Authoring a dedicated low-poly collider is the standard fix and keeps the physics cheap and stable.

1. Install Unity Hub and Unity 2022.3.49f1 (LTS).
2. Clone the repo and open the project folder in Unity Hub.
3. Open Assets/Scenes/SampleScene.unity and press Play.
