The way I did doors is they split in half and they can be open or closed, but they take up the same space either way, and the only thing that changes is whether other things can move into that block.

If a peep is inside a door block when it closes, that's fine - they can still move either direction. They don't stop the door opening or closing either.

It's not realistic, but so far, I have not found any disaster side-effects.

There is one thing that's making me reconsider "door in the middle of block" and instead doing it like minecraft, and that's what effect an open door would have on mob pathing since it's halfway between blocks and blocks travel between them

But I can probably work around it

#EniBlockGame

you can collide with entities (and so the door) now. took a while to figure out how to do efficiently

at the start of each tick, for each entity that has physics, collision boxes are stored for all collidable entities nearby. this prevents ordering issues and having to calculate collision boxes multiple times, which is expensive since it requires firing an event

atm its stored per chunk but i can go more fine grained later if it becomes a performance issue

#EniBlockGame #GameDev #IndieDev

finally wrapped my head around how to make blocks with different orientations so i could have east/west facing doors

and immediately got stuck again trying to figure out the implementation for making them 2 blocks talls :|

which is frustrating since i'm so close to being done with this dang door!
