Please note that this is the old documentation on the last version of Skript I released in 2014.
For up-to-date documentation, please visit the SkriptLang docs, the Skript Hub docs, or the skUnity docs.
Table of Contents
The following is a listing of all possible events you can use to start a trigger with. Each trigger can only have one single event, i.e. you cannot create triggers that are called when any of several events occurrs.

Please also note that the ‘on’ at the start of an event is entirely optional but it just looks better in my opinion, and that most events don't have examples since there is only one way to use them.
