Quick, Easy Steps To Animate A Character in the Unity Engine

Animating Characters in Unity
Unity is one of the premier game engines of the modern age. While perhaps not as powerful as the celebrated Unreal Engine, Unity has been the toolset for thousands of talented game developers and is officially the most popular third-party game development software.

Games like Hollow Knight, Cuphead, Rick and Morty: Virtual Rick-ality, Escape from Tarkov, and Outer Wilds have defined what gaming is capable of.

So how does someone like you take advantage of what Unity has to offer, namely Unity animations?

Characters are the heart and focal point of any game, and good animation is key to a game’s success and level of fun. You can ensure fluid and realistic movements of characters by using the Unity Animator.

Let’s see just how to animate a character in Unity.

Animation


Animation in Unity is probably more straightforward than you might think. Let’s break down some of the critical concepts behind Unity animation to introduce you to the process.

Animation Clips


Animation clips are what make up the brunt of your Unity animation. These are internal or external files placed into Unity to create animation.

These animation clips are an easier way of pinning applicable animations together to create a cohesive whole. Once clips are imported or created within the engine, we move onto animation controllers, giving us better instructions to the engine as to what characters should do next.

Animation Controllers


Animation controllers are, you guessed it, tools that allow you to dictate movements for your character. Animation controllers do this by organizing your various animation clips and assigning them to different commands. Every time you press the ‘X’ key, you could have an animation cycle between crouching and standing up.

Unity makes animator controllers for you once you start inputting animation information, creating clips, and utilizing state machines to make all of this work.

Wait, State Machines?

State machines refer to the fact that in animation, objects or figures perform actions all the time. As such, they’re in a series of states. Characters can be in a state of running, walking, swimming, you name it.

State machines refer to the overall package of all of the aspects of states. The transition between actions, the actions themselves, and different variables make up a state machine.

For example, from an idle position, your character can’t perform a running jump. However, they can perform a regular jump. The state machine is a flowchart of sorts that shows you what is achievable from any given state. State machines are vital aspects of Unity animation.

How to Animate A Character in Unity

Now that we know a little more about the importance of Unity animation, let’s see what some beginning steps toward animating characters are.

Unity Animation


2D animation usually has characters that move from left to right on the screen. Think of all of the early Mario games as fantastic examples of 2D games. To bring a 2D model to life, you’ll first need a few things.

With Unity 3D animation, you need to be more mindful of your surroundings in-game, as characters move in three dimensions, rather than in two different directions.

What You Need to Start Unity Animation


Ideally, you’re going to want somewhat of a primer course on some animating techniques, along with some familiarity with Unity’s user interface. Knowing the user interface is arguably one of the best ways to succeed when using something like the Unity animator.

You should experiment around and create a character of your own. Once you have a character and a simple grasp of some animator mechanics, we can dig right into the animation process.

Sample Animations

Remaining Idle


Unity - Remaining Idle
Remaining idle is one of the most basic animations a character has. Although they may not be doing much during this state, nearly every other animation flows from the idle state. They’ll need a different state, like running, everything grows from the idle state to achieve a running jump.

Creating a subtle and effective idle animation, like breathing, is simply a matter of manipulating your character model’s rigging throughout a few frames. If you’re successful in your animation of the idle state, you will have created a convincing, living, breathing character.

Walking


Unity - Walking
The way your character primarily moves around needs to be animated well if you’re going to have a convincing animation project.

You’re going to need to create a new file dedicated to your walk animation. You need to record each different pose that a character makes when you manipulate their limbs—think of it as like stop motion animation.

Animators move pieces into place, stop, and take pictures and splice them all together to give the appearance of action. Although this animation is more complicated, it’s more or less relatively similar.

Make sure that your walking is convincing, as it’s easy to overlook something and have your walking animation show your character entirely off the ground by accident when walking.
