Unity Physics: Build a Rube Goldberg Machine (No Code)
Unity

Learn Unity physics by building a playful Rube Goldberg machine, no coding required. Across short, hands-on lessons you’ll plan a chain reaction, block out scenes with primitives, add Rigidbody, Hinge and Spring Joints, and troubleshoot common issues like axes, gravity, jitter and edge rails. Finish with a working sequence and a short demo clip for your portfolio. Ideal for beginners or designers wanting a physics refresher.
