Unity Input System (new)

Read input through Unity's Input System package (com.unity.inputsystem 1.x; Unity 6.3 LTS ships 1.20) — action-based, device-agnostic, rebindable. Targets Unity 6.3 LTS. This is the modern replacement for the legacy Input.GetAxis/Input.GetKey Input Manager.

When to use

• Use when setting up movement/jump/fire input, defining an .inputactions asset with action maps and control schemes, wiring a PlayerInput component, reading a Vector2 stick/WASD value, or handling gamepad + keyboard + touch from one set of actions.
• Use when Packages/manifest.json contains com.unity.inputsystem or the project has an *.inputactions asset.

When not to use: rebindable-control architecture across engines → input-systems (this skill is the Unity-specific API). Moving the character once you have the input vector → unity-physics / unity-csharp-scripting.
