Thanks Theo for all the help and info. I will try what you’ve mentioned further on.
With your help I’ve finished the simplest timer example of ofEvent I was able to make and this time without another class as in my previous post. This example is supposed to be very easy to read and understand. The previous code had a custom event in case anyone wants to learn them.
Thanks again forum! 
I’ll leave the code here in case anyone is stuck at the beginning of ofEvents. You will need the fingers.mov video from the videoPlayerExample. This was made in of_v0073_win_cb_release .
