You're Welcome
I see,
So here is what you have at the moment according to the events that you posted not sure if its what you were trying to do though:
Every 3 seconds you create the object "Spr_StarBad"
Then you have on the event that you highlighted:
"Spr_StarBad" on created >>>> wait 8 seconds and set Bullet Speed and Angle
So if you wanted to create every 8 seconds then that is not what was happening as you creating that object every 3 seconds then the Objects don't move because probably they start with Bullet speed = 0 then 8 seconds later you make them move. So you could have easily two objects created and waiting to be move between each spawn.
You may wanna read this to help you understand more about how the events work:

I hope it helps
