Cleaner creep spawn allocations

[brisberg]

Just saw an interesting idea for announcing creep spawns:

https://github.com/simon-watiau/screeps/blob/master/src/population/CreepsIndex.ts#L370

I can have the spawn requests include a reference to the mission requesting it, or some callback function. That way the spawn can directly call the mission when it successfully spawns a creep, to pass them the creep name.

Might be weird because the creep won't exist until next tick.

Yeah kinda nice

The requestors can setup the initial creep memory:

That's definitely better than the hacks I was using before to try to "catch" and detect the new creeps.

Yeah looks like Game.creeps[] will contain the new creep as soon as the Spawn.spawnCreep() call succeeds

Just tested in the simulator. This definitely works, the only caveat is that the spawned creep does not get an ID until next tick. Likely because it needs to be written to the DB to be assigned an ID.

Still very useful, I should use callbacks like this in more places.
