Pop-up Turret

Thing type 111, Pop-up Turret, is a stationary enemy that periodically shoots at the player. It is used in Egg Rock Zone Act 2. Upon spawning, it is retracted into the ground, but it pops up when the player approaches it, shoots once, and moves down, popping up again periodically so long as the player is near it. The Angle of the Thing (or UDMF Argument 1) sets the delay between shots, in tics. An Angle (or Arg 1 value) of 0 or less will set it to the default value, which is 69 tics (slightly less than two seconds).
