Invoke Event

The following nodes are available for triggering events:

Node Name	Description
DidaInvokeEvent	The most commonly used event trigger node; also used to access the EventSubsystem

For example, you can use the DidaInvokeEvent node directly within a blueprint.

concept-invoke-event

Below is an explanation of the relevant parameters:

Parameter	Description
Outer	Used as the `Outer` to instantiate the `Payload`, as well as to access the `EventSubsystem`.
Event	The event to be triggered.
Channel	If not `None`, only listeners with either no channel or the same channel will be triggered.
Payload	Specifies the type of payload parameters to be used.

Once a payload is selected, parameters defined with meta=(ExposeOnSpawn) in the payload will be listed.

concept-invoke-payload

When the node executes, it instantiates the payload and assigns the specified parameters, with the provided object as its Outer.

Additionally, UDidaEventLibrary provides non-K2Node versions of various functions, which can be used as needed.
