And what is an Event?
An event is a chunk of script that an object runs, the process of triggering an event can arise from different circumstances. Some events come about because of the world - collision events, for example, are triggered whenever an agent that responds to boundaries hits a surface that it can not pass through.
Other events can arise from user/creature interaction - pickup and drop events, for example, occur whenever the object is picked up or dropped. Other events can be defined so that they occur at a user defined time - an activate 1 event, for example, usually occurs from a click on the object, and timer events can be used to allow periodic running of a script.
