While making the custom elements for Spiders' Domain (one of my entries to MaGDL), I went with a very naive logic to check if they could spawn things on a particular tile. It amounted to asking whether the entity could move to that tile, and then whether or not there was something like a tunnel or a door there that should prevent something from spawning anyway. The end results included a "queen" which cannot spawn anything if placed in the bog-standard "roach queen spawner" position of stuck against a force arrow and unable to move--because, of course, that makes it fail the "move there" check.

Well, DROD clearly already has logic somewhere that tests a tile properly for whether or not a roach queen would be capable of putting an egg there. Rather than trying to reinvent that particular wheel in scripting, it'd be nice to just have a command that looks at a tile using said logic and outputs a 0 or 1 to _ReturnX or something to indicate whether or not an egg could be spawned there.

Could be part of a more general command that can also check:
-Can a double be placed here
-Can tarstuff babies spawn here
-Can waterskippers spawn here

In some senses I'm so ahead of the curve that I've already sort of done this. I've got a "Wait for open move" command waiting for a merge, which can handle most of the checks for if something can spawn somewhere. Currently it only looks at movement types, but it could be expanded to do other things.

In fact, part of the impetus for implementing this was because the spider queens in your MaGDL entry.
