Introduction

What the plugin does and what it leaves to you.

Footstep System plays footsteps based on two things: the state your character is in, and the surface it is standing on.

Walking on grass and sprinting on metal are two rows in a data asset. You fill the rows in, and the plugin does the rest.

What it does

Looks footsteps up in a Footstep Database asset by state and surface.
Finds where each foot lands in your animations and places the notifies for you.
Fires an On Footstep event with everything it worked out, so you can add your own logic.
Lets you attach Footstep Actions to a single surface, written entirely in Blueprint.
Works in multiplayer, and the default mode sends nothing over the network.

It does not ship any states. States are Gameplay Tags you write yourself, so the plugin never assumes what a walk or a sprint means in your game.
It does not ship any surfaces. Those come from your own physics settings.
It does not ship sounds or effects. It plays yours.
