javascript - Should I use fixed or dynamic time step in a networking game? -


i developing online networking game using box2d js , vert.x server->client framework.

i have searched pros , cons of each , believe dynamic time step better since not assume each client has same processing power, however, there (many) people think fixed time step better.

please enlighten me.

you can throw determinism out window if timesteps not synchronized. when are, determinism difficult.

spending less computation on simulation have real costs may not apparent. each different setting (and in case of dynamic timesteps/iterations, each different individual execution) resulting behavior on same input can different. can have user run on slow hardware can potentially cheat through levels.

determinism perhaps marginally less important outside of multiplayer engine context, not having deterministic system make more difficult reason pretty (gameplay mechanics, game difficulty, exploits) can impact every kind of game can think of. imagine puzzle game wasn't deterministic.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
