If you guys could, yanno, explain what you're talking about...? General rule of thumb, when you ask for help, do not assume that the person reading it is going to understand your references. I do not watch DBZ, nor do I care to do so. As such, without some details included, I read your post as:
"hey, I need this system that does something."
"Yeah, I need that too. It could be done with events?"
"Someone show me how?!"
So, I mean, unless you didn't actually want help, you should probably edit the OP and add a bunch of details and explanations. Assume that noone reading this has seen DBZ ever.. Hell, even a short youdoom video link with explanations and references to the video clip would be better than what's there now >.>
