As an alternative to blend trees for the sake of animating the tools for the character later on, I show how to play directional animations from code by creating an animations set that can decide which direction to return based on a facing input direction.

01:41 - Unity Animator Component
04:27 - Creating Animation Clips
06:28 - Directional Animation Set ScriptableObject
12:10 - Setting Animation from PlayerController Script

In this video, we create states to hold some of our character logic and link those states to the animation sets using dictionaries. However, dictionaries are not serializable in unity out of the box so we can use a free plugin to have a serializable version of a C# dictionary to suit our purposes working in the Unity editor.

20:56 - Migrating Dictionary Code to a New Class
23:43 - Making New Dictionary Class Serializable
24:37 - Wrapup

Setting up player logic for switching between walk, use, and idle animation states purely through code in Unity. This approach overcomes the weaknesses of blend trees for four directional animation by allowing transforms to be animated without blending between the values set in each directions animation. It'll be helpful when we equip our tools to the character's hand later.

This tutorial shows you how to define tools and tool types as scriptable objects, equip them to a players harvesting slot, and allow harvesting of a resource node based on whether the tool being used is of the correct tool type or not. This is part of my bigger series on making a resource harvesting game in Unity. You can get the scripts, demo, and art on Itch.io below!
