Input System Interactions Explained | Press, Hold, Tap, SlowTap, MultiTap - Unity

Today we go over Interactions in Unity's New Input System. I go what makes an interaction, how it impacts the actions, the individual actions themselves, code overview, interaction priority and multiple interactions, and custom interactions.

First I explain what an interaction is within Unity's Input System. Then I go over how the event callbacks work in the Input System, which is important to understand how interactions impact it. Then, I'll be going over each interaction individually, Press, Hold, Tap, SlowTap, and MultiTap. I explain their behavior and how they call the event callbacks in the action. Then I provide a visual explanation on the different interactions to better solidify the point.

After the main explanation is done, I go over priority of interactions, specifically having the interaction on the action versus the binding, and what happens when there are multiple interactions on the same action or binding. There is a visual example provided for that as well.

Finally, I go over a custom interaction which can be added via code or through the Input Action Asset that you create.
