What I Learned Building the Apex Legends Wingmang in VR
What I Realized Constructing the Apex Legends Wingmang in VR 6

Within the decade that I’ve spent finding out and reporting on VR I’ve had the fortune of experiencing a variety of VR sport design—a craft which remains to be removed from ‘discovered’. And whereas I’ve no intention of changing into a sport designer by occupation, I assumed it may be a great studying train to attempt my hand at designing one thing in VR to raised perceive the challenges and alternatives therein. And right here I’d wish to share a bit about what I realized by that course of.

For context, this was a private mission conceived on my own and my developer pal Henry Ventura. We got down to see how successfully we may translate a weapon from a non-VR sport right into a working VR model that maintained the weapon’s ‘character’.

We seemed to the arsenal of Respawn Leisure’s Apex Legends (and its cousin Titanfall) for inspiration. The sport’s iconic weapons are all fairly superbly modeled and animated, giving us an awesome blueprint of each operate and ‘character’ to work from. We selected the Wingman revolver, and right here’s what we got here up with in lower than a day of growth time.

This was constructed with Unreal Engine four working on PC; sadly we gained’t be distributing a demo construct.

What I Realized

Though I helped a bit with textures and sounds, my function on this mission was primarily interplay course—that’s, directing the way in which the weapon, and its varied interactions, ought to really feel.

Select Your Weapon

The primary a part of the method was, in fact, selecting which weapon we have been going to construct. When you have been constructing an precise VR sport with weapons, the kind of weapons you select to make use of can massively affect the remainder of the sport due to how their interactions will dictate each the participant’s consideration and the sport’s total pacing.

The selection of the Wingman revolver was extremely influenced by its one-handed operation. Whereas two-handed weapons can positively be enjoyable in VR video games, additionally they demand extra of the participant’s consideration and consequence within the participant having one much less hand to work together with the surroundings round them.

With the Wingman particularly, the reload gave us an awesome bang for our buck as a result of the participant will get to make use of each palms for the reload without having to dedicate the off-hand fully to the weapon. It’s clear that Valve’s Half-Life: Alyx was additionally constructed round this concept, as the sport options solely single-handed weapons—even going as far as turning a shotgun (just about all the time a two handed weapon) right into a shotgun-pistol.

Character Performing

A serious purpose of this mission was to deliver the Wingman’s important ‘character’—the way in which you think about that it might really feel—into VR. If we have been constructing from scratch, we’d have to spend time determining what that character needs to be. On this case, Respawn already did a lot of that heavy lifting by giving us a really clear imaginative and prescient of the gun’s feel and appear by animations and sounds that we drew upon.

I used to be really fairly shocked how successfully we have been capable of deliver the character of the gun into VR. The Wingman is a hefty gun that looks like one thing an skilled gunslinger would confidently use. Our completed VR model, particularly with physics-driven gun-spinning as an non-obligatory flourish, actually does make one really feel like a badass gunslinger.

Our success in successfully translating the gun’s character into VR is fascinating in itself as a result of it means that designing VR weapons within the ‘conventional manner’ (ie: by animating the way you’d like them to feel and appear) could possibly be an equally legitimate place to begin for figuring how the weapon ought to behave in VR. Within the conventional technique, it’s an animator’s imaginative and prescient which defines the texture; that artistry, it seems, can act as glorious ‘idea artwork’ for a way a gun needs to be designed to really feel in its VR incarnation.

A rigorously designed weapon in VR can make the participant themselves really feel a sure manner. It isn’t nearly pointing the gun at enemies to make them disappear. A VR gun could be virtually like a ‘costume’ that provides gamers license to ‘play act’ in a manner inspired by the sport designer.

Slightly secret… the fan-firing seen within the video (when the off-hand fires the gun by pulling the hammer again) isn’t an actual mechanic, it was the results of ‘performing’. We got here throughout the concept whereas actually taking part in round with the gun and performing out a fantasy.

After we realized how enjoyable it ‘felt’ (regardless that we have been pretending the mechanic existed), we knew we needed to embody it. Since this was prototype, there was no have to construct out the precise mechanic when it may merely be ‘carried out’ to get the purpose throughout. Pretend it ’til you make it.

Communication Throughout Improvement

Whereas we have been growing and testing the Wingman interactions, I discovered it was typically troublesome to articulate precisely what sort of adjustments I’d wish to see. I take it that is regular for all sport design, however it appears very true for VR given the immense freedom that the participant has to work together with objects.

In lots of circumstances certainly one of us could be utilizing the Wingman in VR whereas the opposite watched through screenshare. This work moderately effectively to attempt issues out and discuss them on the fly, however at occasions I used to be wishing that we may merely each be in VR and searching on the identical factor collectively. Merely with the ability to level with my finger in 3D area and have my very own model of the gun to (once more) ‘act out’ how sure issues ought to work, would have sped up growth and made for clearer communication.

Capturing the Video was a Surprisingly Giant Activity That Might Have Been Optimized

I’ve a newfound appreciation for the Valve developer who live-captured the entire pictures for the Half-Life: Alyx trailer, which actually does a great job of promoting what the expertise looks like once you’re really inside it.

We actually wished to have one steady sequence that might each show the total operation of the gun and actually present what it felt like. Between choreographing the actions and training the gun spins and aiming, it took a number of hours to get a shot we have been lastly proud of—and this was solely a 30 second video!

Merely utilizing the gun in a manner that you simply naturally would in VR, and capturing the output display, seemed fairly unhealthy as a result of there was numerous head motion and the cropped discipline of view meant it was laborious to inform what the framing would appear to be to the spectator.

Our course of was to have certainly one of us utilizing the gun in VR whereas screensharing to the opposite. The particular person exterior of VR would assist direct every take to make sure that issues have been framed effectively and that there wasn’t an excessive amount of digicam motion from the spectator’s perspective. In hindsight, there’s just a few issues we may have finished in a different way to hurry up the method and find yourself with a greater consequence.

Whereas the reside course was definitely useful, our greatest stumbling block was the talent wanted for execution! Aiming had no assists and gun-spinning was fully-physics primarily based, so a significant portion of the time it took was merely the apply essential to do all of it with no errors (all whereas guaranteeing the top actions didn’t affect framing). We had tons of takes that have been virtually proper, however we frequently missed a barrel or had another minor stumble.

It definitely would have saved us time if we had scripted the barrels to register a success with every set off pull (no aiming required). Whereas this dangers trying unhealthy if the intention is too far off, it might have given us a a lot bigger margin of error to work with, and allowed us to spend extra time perfecting different features of the shot.

One other helpful change would have been to mission a frustum onto the surroundings that matched the sphere of view of the spectator digicam. This is able to have allowed the particular person in VR to see precisely what portion of the motion could be captured within the last output, and in addition supplied clear suggestions to indicate how a lot the spectator digicam was being moved when the top was moved. A smoothed spectator digicam (as seen in some VR video games) would have helped too.

The tip-all-be-all resolution could be to document the actions by the sport engine in order that we may make minor changes after which re-render the scene after the actual fact. This is able to even have given the choice to render the video in larger constancy (which might be particularly helpful for anybody making a manufacturing VR trailer).

I’m actually proud of how the mission turned out. Not solely was the gun enjoyable to make use of, however I gained a brand new appreciation for the challenges and alternatives of a small slice of VR sport design.

Whereas VR is able to rather more than simply shooters, there continues to be an enormous demand for VR video games primarily based on gun fight. If the business goes to be beholden to that demand, I’d personally like to see extra consideration paid to the ‘character’ and interactions of VR weapons.

To me, the interactions that occur inside arms attain are among the many most compelling elements of a VR sport. VR weapons needs to be considered much less as laser pointers that trigger injury to distant enemies and extra as interactive instruments.

Pondering before everything about how the participant will work together with the gun (somewhat than how the gun will work together with enemies)looks like an important a part of designing a VR gun with character.

Whereas we caught with a design rooted in actuality, this mission has additional satisfied me that there’s an enormous untapped alternative for inventive ‘sci-fi’ weapons that work in completely novel methods which might be uniquely enjoyable in VR. If weapons are going to be the important ‘device’ the participant is given in lots of VR video games, I’d like to extra considering exterior of the lifelike assault rifle, SMG, sniper, shotgun paradigm.
