Ue Input System

This covers Unreal Engine's Enhanced Input system end to end, from plugin setup through InputAction and InputMappingContext assets to C++ binding with the four callback signatures. The trigger and modifier reference is solid, covering the common patterns like Hold, Tap, Pulse, ChordAction, and Combo triggers, plus modifiers for dead zones and axis manipulation. The context check is smart, reminding you to verify whether CommonUI is handling input mode switching or if you're dealing with legacy input migration. It asks the right questions upfront about value types, platforms, and whether you need complex behaviors like hold-to-charge or combos. One thing to note is the modifier table gets cut off in the source, so you'll want the full reference doc for that.
