When you concentrate on essentially the most tough elements of constructing a sport, it is unlikely that the standard door can be entrance of mind–unless you are a sport dev who’s tried doorways earlier than. A Twitter thread by indie dev Stephan Hövelbrinks, who’s engaged on Death Trash, revealed that doorways are notoriously inside sport growth, with builders on titles like The Last Of Us Part 2 and The Witcher 3 chiming in to agree.
Hövelbrinks explains that the most important points come up from doorways being “a dynamic funnel and block within the pathfinding, probably locked, probably destructible, however on the whole as a result of they sit probably between any sport interplay or character to character state of affairs from right here to there.”
Proving his level, locked doorways have been the reason for various game-breaking bugs, even in high-profile AAA games. Hövelbrinks factors out that some AAA devs keep away from utilizing doorways in any respect, resembling your entire Murderer’s Creed collection till Valhalla–though even Valhalla’s implementation of doorways was usually glitchy and not too popular with followers.
The Final of Us Half II co-game director Kurt Margenau wrote a Twitter thread on the topic, speaking about how tough it was to design doorways that labored with fight, stealth, and nonetheless fitted in with the sport’s sensible animations.
Margenau credit the tough sport physics the doorways required to developer Jaros Sinecky, who has already seen approval for his work on TLOU2’s impressive rope physics. Sinecky additionally contributed to the extremely detailed glass-breaking mechanic we investigated last year.
Different builders have chimed in as regards to doorways, with some merely commiserating on how tough they’re, and others explaining how they fastened door-related bugs, or just acquired round having to make use of doorways in any respect.

My answer was to make doorways solely visible: These faux doorways open/shut primarily based on the space to the closest character.
For the occasions after I want an unlockable door, they’ll solely be unlocked, they by no means revert to their locked state.
