Custom Events

Custom Event


A Custom Event is an event that can be called from this behavior (using the trigger event block), or as a response to messages that get sent by other behaviors (using one of the trigger event ... in ... blocks). The former is like a function call. The latter is different from function calls since sending out a message doesn't specify a recipient, so multiple recipients could exist.


Custom Blocks

Custom Block


Lets you create a regular Custom Block.

Global Custom Block

Custom Code

Arbitrary Code


Not an event. Lets you insert arbitrary code into your behavior at the "class" level. You could use this to define functions or add class-level fields, for example. Use code blocks within this wrapper.

Import Statements


Not an event. Lets you add import statements to the beginning of your behavior's "class". Use code blocks within this wrapper.
