Final of Us 2 Dev Reveals How Troublesome It Is to Add Doorways to Video games


Various builders have taken to Twitter to elucidate how troublesome it’s to insert sections involving using doorways in video video games. Apparently, one thing so simple as opening and shutting doorways can break immersion, make the sport clunky, and trigger all kinds of visible and gameplay issues.

What sparked the dialog was a tweet mentioning the above by Loss of life Trash developer Stephan Hövelbrinks. A number of different builders, together with former BioWare designer Damion Schubert and The Final of Us Half II co-director Kurt Margenau, chimed in. Probably the most detailed clarification of the problem got here from Margenau, who tweeted just about The Final of Us II:

We knew that doorways in a stealth situation would add some degree of participant authorship to the house and provides extra alternatives to flee conditions. They block line of sight and sluggish enemies down. This was in step with wanting the participant to re-establish stealth extra usually. However we’re additionally a sport that’s extremely polished animation-wise. If a participant goes to open a door, it may well’t simply magically fly open, the character has to achieve to the doorknob and push it open. However what about closing it behind you? How do you do this whereas sprinting?

We performed round with a number of prototypes to permit the participant to manually shut the door behind them. They have been all not nice. We tried holding buttons, every kind of bizarre schemes. Then how do you animate it? Don’t need to suck the participant into an animation whereas escaping. Lengthy story brief: in fight rigidity the doorways will slowly robotically shut. That is essentially the most player-favoring, as participant door opening slows you down little or no, we don’t even take management away, however they block AI extra successfully. In non-combat rigidity, the doorways keep open, so you’ll be able to see the place you may have explored with out them re-closing. Oh, and, they’re physics primarily based in order that they slam shut behind you when opening them violently i.e. sprinting by means of them.

Margenau concluded his thread by revealing that Naughty Canine ended up creating a brand new physics object, distinctive to its engine, which gamers can push however also can push the participant. Moreover, the developer designed an “insane partial reaching-to-doorknobs” layering system that balances animation constancy and responsiveness.
