Unity Input System Guide

Player controls define how the game feels.

Bad controls destroy gameplay even if everything else works.

Why Use the New Input System

Unity’s new input system supports:

• Mobile touch
• Keyboard
• Gamepad
• VR controllers
• Multiple devices simultaneously

This flexibility makes cross-platform development easier.

---

Designing Input Actions

Create actions like:

• Move
• Jump
• Interact
• Attack

Map them to different devices.

Example concept:

playerInput.actions["Jump"].performed += ctx => Jump();

Separate logic from devices.

---

Cross Platform Advantage

With one system you can support:

• iOS
• Android
• PC
• Console
• WebGL

Minimal code changes required.

---

Final Thoughts

Controls should feel natural across platforms.

Design inputs as systems, not hardcoded keys.
