Hi, please excuse the extreme beginner question, but I am trying to make a pluggin that updates only when the animation is playing. I've tried this:-

main(doc,op)
{
var number,on_off,coffee_tag,store_t,sec,last_time;

doc->SetFps( 25 );

coffee_tag=op->GetFirstTag();

while(coffee_tag)
     {if(instanceof(coffee_tag, CoffeeExpressionTag)) break;
     coffee_tag=coffee_tag->GetNext();
     }
if(!coffee_tag) return;

if(!(coffee_tag#ID_USERDATA:2)) return;

// GET TIME
var t = doc->GetTime();
var sec = t->GetSecond();

if (sec == last_time)return;

number=coffee_tag#ID_USERDATA:1;

println (number);

{
last_time == sec;
}

}

but no joy, any pointers would be greatly appreciated.
Many regards Conor

What kind of plugin? An Expression Tag? We need some more information. The code you show here looks more like code from a Coffee Tag or Coffee Node.

Generally, store values like last_time OUTSIDE the main function.

Hi Jack
it's a Coffee tag, eventually I hope to make a pluggin that saves the user data from my coffee tag to a text document for each frame of my animation, but as you can see it is baby steps at the moment.
If I want to store last_time outside the main function, should this go at the end of the script?

With a COFFEE tag you would do something like this:

> \> var lasttime; \> \> main(doc,op) \> { \>      if (!lasttime) lasttime = doc->GetTime(); //initialize lasttime \> \>      var time = doc->GetTime(); //current document time \> \>      if (time->IsEQ(lasttime)) \>           println("equal"); //times are equal \>      else \>           println("not equal"); //times are not equal, animation is playing \> \>      lasttime = doc->GetTime(); //write current time back to lasttime \> } \>

lasttime is a global variable, outside of main(doc,op).

In a plugin you can store the time in a local class variable. Rule of thumb, avoid global variables.
