Notes

  • Be careful using random numbers in multiplayer, each client will come up with a different result. See multiplayer tutorials for more general information about locality.
  • The number returned is unlikely to be a whole number.
    To return a whole number use either ceil or floor together with random.
x=floor(random 5) will return 0,1,2,3 or 4. x=ceil(random 5) will return 1,2,3,4 or 5.
