You can'y store live objects in Memory, store the id of game objects.

something like:

var newstorePlaces = new Array();

for (var i in storePlaces) {

var sp = storePlaces[i];

newstorePlaces.push(sp.id);

}

creep.memory.places = newstorePlaces;

and then Game.getObjectById() to get the objects back again.

Hi,

Are any screeps players at 33c3? and if so do you want to meetup and complain about how much forgetting to check for undefined is annoying you?
