Custom event?

[GaryP]

I was reading somewhere you could create a custom event for an object.  Is this true, and how is it done?

Like a custom death onDeath something happens.

I suspect you are talking about eventhandlers.     You can attach them to a unit and when the relevant thing happens (for example the unit fires or gets hit) then the eventhandlers calls a script.    Check the EdDepot for more details.
