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
- targetname <target_source>
- 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.
