In RPG Maker, you have events on the map that can be triggered when the player is either standing on top of them or in front of them. When a player wishes to trigger an event, they press the "action" button, which by default is the Z or Enter key. When an event is triggered, they will execute the entire list of commands.
However, what happens if you want to allow a player to interact with an event in different ways? For example, if a player walks up to an event and talks to it normally, they might just have friendly conversation.
On the other hand, if a player walks up to an event and presses the A key, this might issue a challenge to the event to a mini-game, and the event will ask you if you're sure you want to do this.
This plugin allows you to separate an event's list of commands into different sections. Depending on how the event is triggered, a different section would run, allowing you to create unique behaviors when the player interacts with an event.
