Knockback NavMesh Agents (AI Series 51)

In this tutorial repository and accompanying video you will learn how to knock back NavMeshAgents using Physics & Forces!

Youtube Tutorial

Quickstart

This repo uses the Scriptable Object Gun System as of branch part-14 to handle shooting. This was then modified to add knockback. There's nothing specific to this system required to make the knockback effect work. It just was a launching point to allow this to focus on the knockback instead of implementing a bunch of systems from scratch.

  1. Import Unity Particle Pack (free)
  2. Click play!

Everything should be working from there.

Key Classes

While I highly recommend you check out the video for a complete understanding, I also understand that's not everybody's cup-of-tea. Here are the key classes if you just want to explore:

  1. IKnockbackable.cs - Interface to allow arbitrary objects to be knocked back
  2. EnemyMovement.cs - Implements IKnockbackable to handle how to get knocked back.
  3. KnockbackOnCollision.cs - Applies force to IKnockbackables OnCollisionEnter
  4. GunScriptableObject.cs - Applies force to IKnockbackables when bullets make impact
  5. KnockbackConfigScriptableObject.cs - Houses the configuration for the knockback effect as well as calculating the
