10 Tips for First-Person Game Animation in Blender

Before we get into the technical stuff of setting up game projects and animation, I want to take share some of the interesting tips and tricks that I found while researching the topic of first-person game animation.

I will also share some resources that you can check out if you want to learn more beyond what’s covered in this course. 

First up, some general do’s and don’ts. 

In first-person games, gameplay comes first

While we want our animations to look cool, it’s more important to make sure that they communicate the action without getting in the way of the player. 

A short, snappy, but otherwise boring animation can actually be better than a fancy one with lots of anticipation and flourish because your player is going to be watching it hundreds - if not thousands of times. 

It might be fun the first couple of times, but after that, the distraction or extra time it takes can be frustrating. You don’t want to make your player wait around an extra second every time they do an action just so you can show off your cool skills. 

That said, we want to try to use the limited time we have and make things feel fluid, natural and fun. Just be aware that it’s a secondary goal. 

Check out this video by New Frame Plus on the animation of Smash Bros characters to see how you can strike a great balance between style and function. They use the fact that they only have a few frames to inform the style and end up with a really satisfying result. 

I’d also highly recommend his video on Overwatch's first-person animation and how the different animation styles for different characters can convey personality

It’s a perfect example of how, if you’re really careful, you can have your cake and eat it too when it comes to style vs. functionality. I’m going to try to strike a good balance in this course, but feel free to lean a little more one way or the other if you think mine is either too boring or too fast. 

Animate the first frame, but don't use it in-game

A common technique for making your animations feel snappy to the player is to not start on the first frame. When animating, you obviously need that first frame of idleness to make sure the transition feels natural, but in the game, you can start on the second frame and jump the player right into the action as soon as they hit that button. 

Don't block your game player's view

Talking about not frustrating the player: don’t block whatever they are trying to look at with your animations. This GDC talk by David Helsby about the first person animation of Destiny refers to the Combat Corridor, the area down the middle of the screen that the player is focused on. 

Try to keep that clear as much as you can so that they don’t miss anything important. 

Framing the reticle

In that same talk, David also mentions the idea of framing the reticle. It’s a nice touch that just feels good and instead of blocking the player you’re helping them stay focused on that most important area

Don't make your player sick when animating the camera

Another great lesson from him is why you should be super careful when animating the camera. When we run, our head stays somewhat stable but still rotates and moves a noticeable amount. 

But if you try to animate that, you’re going to make your players sick because their sense of balance while sitting and what they’re seeing in the game don’t line up - that misalignment is what triggers motion sickness. 

If any of you have trouble reading while riding in a car, you know what I mean. It's ok to translate it a bit for effect if you really need a camera shake but stay far away from rotation, especially while walking, running, or when the player is directly in control of the action. 

If you need to throw some in for effect during a cutscene as I did for my shot of the robot getting up in my first-person animation course, that's fine, but do it sparingly. 

Use two cameras with separate focal lengths

I also thought it was interesting that in Destiny and a lot of other first-person shooter games, there is a second camera for the character with its own field of view. 

Maybe your game has an adjustable field of view, or maybe you decide that you need to change the focal length later. Well, if you only use one camera, all that hard work you’ve done on the animations is suddenly out the window because it totally alters how it looks and feels. 

The solution: have one camera for the player with a set field of view! We just copied Destiny and used 77 because it felt good, and then a second camera for everything else that can be freely adjusted to your liking without messing stuff up. 

Parent the gun root and the left hand to the right hand

Technically it works either way to have the hand parented to the gun or the gun parented to the hand, but I found it easier to work with the gun parented to the hand so that all of the character’s movements are in one action and all of the gun’s movements are in another. 

Overall, you’ll end up with fewer actions to deal with and it will be more intuitive to animate. You can then parent the left hand to the right hand or the gun so that it follows along. 

Use actions for each animation

The next question is whether to animate it all in one long action or break it up into multiple actions. While it’s another case of you can technically do either, I found it a lot easier to manage by making a different action for each movement and then using the NLA editor to arrange them into a sequence. That way the actions for the character and the actions for the gun won’t get out of sync or confused as you work your way through them. Just be sure that you keyframe ALL the important values including constraint influences so that when you change something in another strip down the road things won’t get all funky. 

Save important poses in the pose library

As you work, save a pose in the pose library for the default poses like idle for each weapon, iron sights, etc. so you can easily revert back to them at any time. Since it’ll be different from your resting pose, you won’t be able to Alt+G and Alt+R your way back to safety. 

Structure your files for fewer headaches

Lastly, we need to structure our assets so that they import well into Unity or Unreal. In the course, I show you how to link two separate asset files into a new animation file using proxies or the new library overrides, and then take the baked animation data back into the individual files for cleaner exporting. This is the way to go if you’re working with a team or a huge number of assets, but if you’re just doing a few simple animations for one character with only a couple weapons, then it might not be worth that extra hassle and you can just do it all in one file and not worry about it.
