I am creating a pen with twiggy trees and grass gekkos inside, so that if one wants to collect twigs and grass they can just go in and press spacebar. Yes this is probably inefficient but I'd like to make it, but I've got lots of questions about how twiggy trees and grass gekkos work. First of all, how do twiggy trees drop twigs? Is it that every time they grow they check to see if there is room around them to drop one? Or is it just a random chance to drop some? If a grass gekko is too close while it is growing to a new phase, will that stop it from dropping a twig? Additionally, what is the minimum distance other trees have to be to make sure that it will drop a twig? As for the gekkos, will grass turn into gekkos if there is already a herd in that area?
Thank you if you know the answer to any of these questions!
