Now we need to decide in the case of collisions if:
- Doors violently push anyone out of the way, possibly “crushing” them into walls or
- Force themselves back closed, turning any random NPC / obstacle on the other side into an unbeatable lock or
- Just trap an unfortunate NPC in a corner on the other side, or
- If they use the physics system to swing open, in which case they’ll look smooth but possibly bonk the player/actor going through them a few times and could potentially (and comically) insta-kill them if physics is feeling grumpy.
The frustratingly comedic unintended results of any choice makes for great organic marketing though.
Gamedev is magical.
Aside: Know what did this really well though? Resident Evil games after RE:4.
The ability to “slowly quietly open”, and then at any time decide to violently action-hero kick it open to send a zombie on the other side flying, was genius.
They might when folk gotta brick tho. :P
