Entity Description

An entity that fires a timer event at regular, or random, intervals. It can also be set to oscillate between a high and low end, in which case it will fire alternating high/low outputs each time it fires.
  • An oscillator's first output will be an OnTimerHigh output.
  • Use with logic_case for extremely random events.
  • Could be used to deploy env_headcrabcanisters at random intervals, instead of using fixed delays on the inputs.

Keyvalues

Defines the name that other entities refer to this entity by.
  • hammerid [Episode Two Update]
<integer readonly> This id is used for debugging purposes in Hammer.
  • StartDisabled
<boolean>
  • UseRandomTime
<boolean> If set, fires randomly at an interval from the last trigger.
  • LowerRandomBound
<float> If UseRandomTime is set, this is the minimum time between timer fires. The time will be a random number between this and the UpperRandomBound.
  • UpperRandomBound
<float> If UseRandomTime is set, this is the maximum time between timer fires. The time will be a random number between the LowerRandomBound and this.
  • RefireTime
<float> If UseRandomTime isn't set, this is the interval between timer fires, in seconds.
