TimerEvent Class
Reference
#include <xsi_timerevent.h>
A TimerEvent represents a system timer and allows you to specify the interval and the delay time at which a timer elapses. Timers in Softimage are independent of the timeline clock and can be used to produce recurrent work accurately. For example, you can implement an autosave mechanism with a TimerEvent.
The TimerEvent class derives from EventInfo and can be managed like a regular Softimage event. Use PluginRegistrar::RegisterTimerEvent to register them and Application::GetEventInfos to access them. Timer events can be suspended with muting and resumed by un-muting (see EventInfo::PutMute). You can reset a timer with TimerEvent.Reset.

CString LoadTimerEventPluginHelper();

CString strEventPlugin = LoadTimerEventPluginHelper();
// Iterate over the all event objects.
Application app;
CRefArray eventInfoArray = app.GetEventInfos();
for (LONG i=0; i<eventInfoArray.GetCount(); i++ )
{
EventInfo eventInfo = eventInfoArray[i];
CString strName = eventInfo.GetName();
bool bTimerEvent = eventInfo.IsA( siTimerEvent );
app.LogMessage( str + L":" + CString(bTimerEvent) );
}
// Unload the plugin and deletes it
app.UnloadPlugin( strEventPlugin, true );

CValue retVal;

// Tell the wizard to register the following timer event
eventWizard.PutParameterValue(L"siOnTimer", true );
eventWizard.PutParameterValue(L"siOnTimer", CString(L"MyOnTimerEvent") );
// For the purpose of this example we use internal commands that are
// part of the Event Wizard implementation to generate a plug-in
// containing the new events

| ) |
Stops and re-starts this TimerEvent with new timer values.
| in_interval | This value specifies, in milliseconds, the amount of time to wait between each timer invocation. If the value is 0, the event timer is stopped (muted) after the first invocation. The timer can be re-started again by un-muting the event. If the value > 0, the timer will elapse indefinitely. |
| in_delay | The delay value, in milliseconds, is the amount of time to wait until the timer is first invoked. If the delay is set to 0 (default), the timer starts immediately. |
