The player input mapping is configured inside IMC_Default, located in RetroHorrorEngine/Input/Mappings

This asset is referenced from the player BP.

Some bindings are fixed to an InputTag inside IC_MainCharacter, which pairs an input binding with a specific ability.
Player abilities will be granted by AbilitySets (either at start or when a weapon is equipped). This will bind a specific ability to an InputTag


The default AbilitySet is assigned on the PlayerState and the included abilities are given when the game starts.
