Hi
I’am learning how to use Unreal engine 4 blueprints, so I’am copy some BluePrints from the project Content examples which display how to use Blueprint
Right now, i’am using the blueprint_communication, i’am at the first exercice with BP_Light_Bulb_Basic and BP_Generic_Button. I create a copy of each of this instance BP_Light_Bulb_Basic3 and BP_Generic_Button2
I think I reproduce with succes the blueprints but I don’t know the trigger “Toggle Light” " is not trigger. I got the color switch from red to green but the customEvent on “Toggle ligh” on BP_Light_Bulb_Basic3 is not trigger.
So what I did , it’s on the original BP_Generic_Button i plug my custom Light (BP_Light_Bubl_Basic3) and the BP_Generic_Button can’t event call my generic light trigger. So I think I miss something on the process . Do i have to record the custom trigger somewhere on "BP_Generic_Button " ? Is their someone who can help ? If theirs a tutorial for this project ?
The same thing happens for an “event dispatcher” 
Thanks!
