logic_timer is a point entity available in all Source games. fires an output at regular or random intervals. It can optionally alternate between a "high" and a "low" output.

Tip:Use with logic_case for extremely random events.

Keyvalues

Name (targetname) <string>

The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.

Use Random Time (UseRandomTime) <boolean>

Makes the entity fire at random intervals. Range of values is restricted by the next two KVs.

Minimum Random Interval (LowerRandomBound) <float>

If "Use Random Time" is set, this is the minimum time between timer fires. The time will be a random number between this and the "Maximum Random Interval".

Maximum Random Interval (UpperRandomBound) <float>

If "Use Random Time" is set, this is the maximum time between timer fires. The time will be a random number between the "Minimum Random Interval" and this.

Refire Interval (RefireTime) <float>

If "Use Random Time" isn't set, this is the time between timer fires, in seconds. Make sure output delay times are less than this value.

Start Disabled (StartDisabled) <boolean>

Stay dormant until activated (with theEnableinput).

Flags

Oscillator : [1]

(alternates between OnTimerHigh and OnTimerLow outputs)

Tip:It will start with OnTimerLow, and all the odd-numbered refires will be OnTimerLow.

Inputs

RefireTime <float>

Set a new Refire Interval.

ResetTimer

Reset the timer. It will fire after the Refire Interval expires.

FireTimer

Force the timer to fire immediately.

Enable

Enable the timer.

Note:Enabling the entity resets its timer.

Disable

Disable the timer.

Toggle

Toggle the timer on/off.

LowerRandomBound <float>

Set a new Minimum Random Interval.

UpperRandomBound <float>

Set a new Maximum Random Interval.

AddToTimer <float>

Add time to the timer if it is currently enabled. Does not change the Refire Interval.

SubtractFromTimer <float>

Subtract time from the timer if it is currently enabled. Does not change the Refire Interval.

Outputs

OnTimer

Fired when the timer expires.

OnTimerHigh

Fired every other time for an oscillating timer.

OnTimerLow

Fired every other time for an oscillating timer.
