BlizzCon 2017: Overwatch Lead Engineer on the Fear of Teleportation, Battle Royale Mode, and More

At BlizzCon 2017, common hero shooter Overwatch received a brand new character so that you can play as – Moira – in addition to a brand new map referred to as BlizzardWorld. While updates like this are par for the course given Blizzard’s consideration to Overwatch, it made us marvel what the technical ramifications of such strikes are to a sport that’s been receiving regular updates since its inception. Gadgets 360 spoke to Tim Ford, Lead Engineer for Gameplay Systems on Overwatch at Blizzard to seek out out extra.

“If there’s one factor that all the time scares me in the case of new characters, [it] is teleportation,” says Ford. “Moira would not precisely teleport. She turns invisible and then she strikes. That’s nice. Sombra teleports. D.Va technically teleports as a result of she summons a mech and will get in that. Tracer teleports. Those heroes give us the most grief [as they’re susceptible to glitches and exploits that break the game]. At launch Reaper gave us a lot grief as a result of he teleports. So my first intuition in the case of new heroes is: ’Can she teleport? No? Cool. How many legs does she have?’”

“These are some of the issues. Orisa for instance is a quadruped [which is challenging] as a result of we’ve not achieved any animation methods for quadrupeds but, in order that’s going to be a tech concern proper there,” Ford explains.


In phrases of tech, Overwatch doesn’t use a third-party sport engine like Unreal or Unity. Instead, it makes use of a set of customized instruments developed at Blizzard. Ford shed mild on Overwatch’s engine.

“It’s a proprietary customized engine, the sport is in C++, our instruments are C++ and C#,” he says. “We have a very senior team who have been exposed to not only a lot of proprietary engines made within Blizzard but also, off the shelf engines that are available to the industry at large so we very much stand on the shoulder of giants when we make an engine for a game like Overwatch.”

“We have been in a position to take learnings from all the means like Quake World, to some of the earliest on-line video games, via Source [engine games], via a complete bunch of different applied sciences even studying up white papers from the groups behind Tribes,” he says.

BlizzardWorld is one of the new maps coming to Overwatch early subsequent 12 months.

With Overwatch being out there on the PS4, Xbox One, and Windows PC, it’s one of the uncommon Blizzard video games that’s not on the Mac. It’s odd contemplating that each different Blizzard title has graced Apple’s line of computer systems. Ford defined why Overwatch is not going to be making it to the Mac.

“We haven’t any plans of giving this sport on the Mac,” says Ford. “There are a number of expertise choices that Apple has made that has made it slightly troublesome for us to launch Overwatch in the means we would like it to be consumed, and that’s the reason we’ve not pursued it.”

On the subject of platform choices, we introduced up how the Xbox One model of Overwatch has extra achievements when in comparison with the PS4’s trophies – Sony’s reply to achievements.

“I am unable to provide you with the particular particulars, I do not recall of the high of my head,” he says. “But I do know they need to do with simply the totally different guidelines and preparations that every of the console producers have with respect to trophies and achievements so to talk. Yeah, that is all I can say intimately.”

The dialog strikes onto Overwatch’s netcode. Despite being a web based multiplayer sport, it’s been completely playable for us even through 3G and 4G connections, utilizing our telephones as hotspots. Ford tells us it was found early on improvement when he was visiting a pal in North Carolina, and couldn’t hook up with the W-iFi community.

“Whenever I related to his Wi-Fi the complete Internet would go down for the total home,” he says. “I attempted tethering from my telephone and performed from North Carolina connecting to servers in LA over my cellphone and it labored nice. I used to be taking part in on-line on-line with Phil Orwig, one of our internet code engineers and I informed him ‘I am taking part in on a cellphone proper now, the sport runs incredible, that is going to work’ we had that working years in the past actually early. I must play nonstop for per week straight to even get near our 2GB restrict.”

BlizzardWorld has callbacks to different Blizzard video games like StarCraft.

This would imply that if Blizzard determined to carry Overwatch to the Nintendo Switch, the internet code wouldn’t be the limiting issue. Ford replied in the affirmative.

“No plans to bring it to the Switch. Though netcode wouldn’t be the problem there,” he says.

With video games like Playerunknown’s Battlegrounds and Fortnite have popularised the Battle Royale style, we needed to ask if Blizzard had plans to carry one thing just like Overwatch.

“That would be really fun. We certainly fantasise what Battle Royale would be like in the Overwatch universe. But we have nothing to announce as of now. It’s cool to see genres like that pick up steam and really see how industries react to a new genre as the case may be,” he says, then hints at potential technical limitations.

“That’s a factor [the net code] when you talk about games at that scale, that’s absolutely a factor. It’s certainly an exciting assignment for me as an engineer who has worked on game architecture and net code to solve that problem. Overwatch as it is today works with 12 players.”

Finally, we requested if Blizzard had plans in place emigrate PS4 and Xbox One Overwatch gamers to the next-generation of consoles. He left us with this.

“We’d try to do right by the players under the constraints of the first party platforms that’s the best answer I can give. It’s too speculative at this point. One guiding value for us that’s been doing really well is do right by players.”
