Ninja Input
Ninja Input is a focused layer on top of Unreal Engine's Enhanced Input System. It cleanly separates input handling from your Character and Pawn code, while giving you a fast, extensible path in Blueprints or C++.
Out of the box, it includes a robust Input Manager, a library of Input Handlers, GAS hooks, an animation-aware input buffer, input remapping, and support for player user settings.
Main Features
Enhanced Input integration
Works directly with Epic's actions, triggers, modifiers, and mapping contexts. Keep using your existing EI assets.Input Manager component
Centralizes mapping context install/uninstall, handler dispatch, and lifecycle hooks to cut boilerplate.Handler collection
Ready-made handlers for common patterns (pressed/held/repeat, axis driving, toggles, gameplay events), extendable in BP/C++.GAS integration
Activate/cancel abilities and fire gameplay events with minimal glue. Plays nicely with Ninja GAS and Ninja Combat.Animation-based input buffer
Buffer windows aligned with montages/notify windows to avoid dropped inputs during transitions.User settings & modifiers
Built-in settings for invert XY and sensitivity (mouse X/Y, gamepad), with matching Input Modifiers that read from the settings object.Input remapping pipeline
End-to-end remapping workflow (UI → ViewModels → save/apply) on top of Enhanced Input. See the remapping setup.Editor integration
Contextual asset menus and a Project Settings page for quick configuration.
