Event in Blueprint

There is something I like to do in my Blueprint.

I like to activate a event action in a Blueprint, that is not place in my game, at least until the game is load up.

I like to make it were, when a egg spawn if it is a white one and it hit or overlaps my character, it will activate a flipbook
sprite and then go back to old flipbook sprite. But if it is a color egg it will add points. If you can give me some answer
to make this possible, ill will be so happy. Please don’t recommend the video Braid that’s don’t help with spawn items
that can activate flip book in character blueprint.

Thanks for taking a time to read this.
