Where are docs about Game Constants?

Question

In the tutorial I'm seeing: Game.HOSTILE_CREEPS

var targets = creep.room.find(Game.HOSTILE_CREEPS);

No where in the docs do I see anything that tells me this is possible. Where would I find out more about these constants?

Answer 2

If you look at the docs: http://screeps.com/docs/Room.php#find

You'll see a little button with three dots in it, click it and it will show the list of constants. A lot of the functions have this additional info.

Answer 3

Try the doc for the find(...) function on the page for room

I would say those are pretty self explanatory
