game.end_round

This function ends the round when called.

Example

if game.round_time_limit > 0 and game.round_timer.is_zero() then
   game.end_round()
   --
   -- That's right: the round timer doesn't automatically end the round. Bungie 
   -- probably set it up that way so that Invasion could use the timer for each 
   -- individual phase.
