working more on spider-behavior and finally adding some sound effects. the sound isn't particularly _good_ yet, but it exists, at least!

pathfinding for large agents: the spider patrols by default and chases you when you're in a place that it can reach (it can't fit through smaller doorways)
eventually this will have some stealthy line-of-sight stuff, but for now the spider just has magic awareness

went down a rabbit-hole thinking about how to get the ambient light level to change as you moved long distances, ended up with a baked lightmap

started adding support for a moving camera - this is harder than usual in this game, because of the lighting system!
getting more and more interested in making the whole game one continuous/seamless map, instead of doing room-transitions...

kinda dry, but i've been making a custom language for dialogue/scenario authoring for the past few days. sorta like yarn spinner, where you can mix "coding-script" logic and "theater-script" dialogue. it's finally executing some code! video of this script running in the next post

making a map editor, partly to make it faster to set up rooms, but also so i can auto-generate these red sectors...
sectors are always rectangles, so any two points inside the same sector are guaranteed to have line-of-sight to each other. this should allow a much faster raycasting strategy!
