error in reference variable

[william5642]

Hi

I am trying to test event dispatcher and communication from main event to listener event so I created these two blueprints

But I get the following error:
Blueprint Runtime Error: "Accessed None trying to read property BossDiedRef". Node: Bind Event to On Boss Died Graph: EventGraph Function: Execute Ubergraph BP Event Listen Blueprint: BP_EventListen

How to fix this just to make event listener display only string message on the screen

how do they get into the scene?spawned or placed

Placed

[baobao4435]

then you could try putting a delay until next tick before binding the dispatcher.

I tried now to attach reference to the bind event but I get error from the reference variable

Your original boss ref is missing…use that one

have you used the straw tool to select the boss ref?

@baobao4435

have you used the straw tool to select the boss ref?

No. Selected the blueprint from the drop down menu
