Description:
This is a code that works only for CTF or death CTF. When a player carries the red/blue flag and dies, it will move the red/blue base to the player instead of the flag back to the red/blue base. Because the server has to have a different way of detecting when a player loses the flag, there can be an error in the position of the bases. This is why this script doesn't work well for open levels like JE. Still, it can be fun to change the overplayed gamemode CTF a bit :)

  //Change the global base variable to the new one
  if (jjObjects[NewBase].var[1] == BASE::BLUE)
    BlueBase = NewBase;

    RedBase = NewBase;
