~~Title: OnPeriodicTimer~~
<pageheader/>

The **OnPeriodicTimer** event can be implemented by a [[:scripting:script_add-ins|script add-in]] to have Opus call your script at regular intervals. The **[[..:scripting_objects:dopus|DOpus]].SetTimer** method can be used to create timers, and your **OnPeriodicTimer** method will be called regularly for each timer you create.
