Your First Mechanic — Building the Core Loop in Unity
Build one working mechanic in Unity — the heart of your game — using Claude Code to assist.
Email subject:Your First Mechanic — Building the Core Loop in Unity
Topics Covered
- •The core loop: the 1-3 actions a player repeats throughout your game. Everything else is scaffolding.
- •Example loops: Tap to jump (endless runner) → Swipe to match (puzzle) → Click to place (tower defence) → WASD to explore (RPG)
- •Build it ugly first: no art, primitive shapes, hardcoded values. Just make the mechanic feel right.
- •Input: Unity's new Input System. Ask Claude Code: 'Write a Unity C# script using the new Input System that handles [your input]'
- •Physics vs Transform: Rigidbody.AddForce for physics-simulated movement, Transform.Translate for direct control. Know which you need.
- •Playtest the mechanic alone: remove everything else. Does it feel good? Would you play this for 30 seconds?
