Hi. I am newby on the blueprints side of the UE4. I cant fix the issue three full days allready. Help me please, my head is blowing. I need to communicate two different blueprints - to send the variable from one blueprint to the other blueprint to move the component of second blueprint. The first one is Widget blueprint(slider).
I made it to change the parameter value of material collection. Then i want to the same widged sent the variable - a value of that slider to a different actor blueprint - simple actor blueprint, that will be placed in the level (there are may be several actors of this blueprint on the level).
And one of its component - NiagaraSystem will be moved according to SliderValue of the Widget. I dont know what to do - i watched tens of videos, tried Blueprint Interface, Casting, and all other stuf that i found on the youtube and forums. I am doing something wrong - nothing works. Guys, help me please. And I am a beginner, I would really like you to answer me in detail, otherwise I just won’t understand.
Above, here called Widget Reference - you can create it by right clicking the Return Value pin on the Create Widget node and then, ideally, give it a meaningful name.
When it comes to using a setup you described above, the most convenient way to pass data from the widget to the actor would be through a dispatcher, as seen in the image above. A slider already has one so there’s no need to add a custom one:
This way, whenever the slider’s value changes, this event in the actor will execute. You will want to connect the white execution wire of that event to the Set Relative Location node.
