But structure of event is same all the time.

Event input

• self - entity trigger event is being processed on
• activator - who lets event go (usually player)
• parameters - instructions for trigger event, fetched from "targetparm" field of self.

Event rules

• Instructions are case insensative
• ';' is the separator between instructions
• If trigger instructions not begin with "SELECT ", "SELECT TARGETS;" is automatically added
• Empty instructions defaults to "SELECT TARGETS;CALL"
