func_rotating - Brush Entity

Attributes

• Name (targetname) - Property used to identify entities.
• Render FX (renderfx) - Gives objects special render effects. Think of it as modifying whatever the Render Mode puts out. The options are as follows:
  • 0 = Normal
  • 1 = Slow Pulse
  • 2 = Fast Pulse
  • 3 = Slow Wide Pulse
  • 4 = Fast Wide Pulse
  • 5 = Slow Fade Away
  • 6 = Fast Fade Away
  • 7 = Slow Become Solid
  • 8 = Fast Become Solid
  • 9 = Slow Strobe
  • 10 = Fast Strobe
  • 11 = Faster Strobe
  • 12 = Slow Flicker
  • 13 = Fast Flicker
  • 14 = Constant Glow
  • 15 = Distort
  • 16 = Hologram (Distort and Fade)
• Render Mode (rendermode) - Controls the type of rendering that is used for an object. Options are:
  • 0 = Normal
  • 1 = Color
  • 2 = Texture
  • 3 = Glow
  • 4 = Solid
  • 5 = Additive
• Pitch Yaw Roll (angles) - Sets the pitch (up / down), yaw (left / right) and roll (bank) respectively. The compass in WorldCraft / Hammer corresponds to Yaw. The settings are not always (or not all) used.
• Global Entity name (globalname)
• FX Amount (renderamt)
• FX Color (rendercolor)
• ZHLT Lightflags (zhlt_lightflags)
• Light Origin Target (light_origin)
• Rotation Speed (speed) - This is the maximum speed the rotating object will acheive.
• Volume (volume) - Sound volume from 0 to 10 (10 loudest).
• Friction (fanfriction) - (1-100) If the Acc/Dcc flag is enabled, this value determines the time it takes to reach full speed or to stop after being triggered. Higher values means less friction and higher acceleration.
• Fan Sounds (sounds) - The sound to make while moving. Values:
  • 0 = no sound (common/null.wav)
  • 1 = fast whine (fans/fan1.wav)
  • 2 = slow rush (fans/fan2.wav)
  • 3 = medium rickety (fans/fan3.wav)
  • 4 = fast beating (fans/fan4.wav)
  • 5 = slow smooth (fans/fan5.wav)
• WAV Name (message) - The path / filename of a custom movement sound to be played (overrides Fan Sounds).
• _minlight (_minlight) - Minimum light level.
• X Y Z - Move here after lighting (spawnorigin)
• Damage inflicted when blocked (dmg) - If the player blocks the entity's movement, this amount of damage will be dealt.

Flags

• Start On (1)
• Reverse Direction (2) - Set this flag to make the brush turn in the opposite direction.
• X axis (4) - If enabled, the rotation will be in the X axis.
• Y axis (8) - If enabled, the rotation will be in the Y axis.
• Acc/Dcc (16) - If enabled, the entity will accelerate and decelerate from maximum speed based on the Friction property.
• Fan Pain (32) - With this enabled, the player will be hurt when coming into contact with the brush.
• Not Solid (64)
• Small Radius (128) - Sets sound range to low.
• Medium Radius (256) - Sets sound range to medium.
• Large Radius (512) - Sets sound range to high. Default if none is set.

Notes

• Often used to create fans.
• An origin brush needs to be part of the entity to specify its axis of rotation.
• Rotates around the Z-axis by default.
• The equation below runs every 0.1s to apply acceleration/deceleration (conditional to Acc/Dcc (16) flag being enabled):

  velocity ±= speed * fanfriction/100

• spawnorigin and light_origin are two different ways to achieve the same effect: having the lighting come from a different place from where the entity is placed in-game. The former is a primitive method done on map load, peculiar to this entity, while the latter is standard across all brush entities with ZHLT and its derivatives. The latter is always preferred.
