Do You want triggers?
Heres how I do it!
Flow: Interface sends a message between trigger and pawn(or any actor interface is attached to)
This works for me since I’m pulling player names, locations, etc. and sending that information out to other places
Make function inside blueprint interface, no input or output needed
Spawn/ Attach as child, attach to actor/pawn
Heres an example if you just plan on sending the message to yourself
Click blueprint properties and add interface on the right, do this for both trigger and actor.
Below I’m using interface to send a message directly into my actor with inputs.
Set up trigger
Iv set it to trigger for players
Find target, send message (function name is message)
You can use find all actors with interface instead of find all actors of class
Heres an example for self-message.
This is a learning process for me too, if anyone has a better way post below!
