In this video, I’m going to explain all 10 Input Modifiers in Unreal Engine in under 3 minutes.
Input Modifiers are a part of Unreal’s Enhanced Input system for defining the inputs of your game. Input Modifiers take the raw values that come directly from the inputs and modify those values in some way before passing them on to the Input Triggers.
The Dead Zone Modifier is used to fix the issue of thumbsticks not being exactly centered. Starting from the exact center of the thumbstick, and going outward in all directions to the value set by the Lower Threshold property, this will create what is called a “dead zone” around the center where no input will be registered.
The Negate Modifier will multiply the value of any input by -1. This is commonly used to have the input affect the opposite direction of an axis. For example, it is commonly used to invert the aim or look controls, causing downward movement of the input to have the player look up, and vice-versa.
