Collect sequence of objects to end game

How do I create a blueprint that ends the game when three objects are collected in a specific order and increments a counter accordingly?

So when object A, then B then C is collected the counter increments to 3 but the objects can’t be collected in any other order and don’t increment the counter either?

Thanks for that franktech, is there a tutorial of this anywhere that I could follow in practice?

Additionally how would you do this without using blueprints, I’m no good as a programmer

Thanks for that, I’ll have a look much appreciated!

But I’m wondering if there is a tutorial out there specifically for sequencing pickups, I probably will struggle otherwise.

thanks for all your kind help anyhow, it’s much appreciated frank!

I’m struggling terribly I think if I add this it might clarify what I’m trying to do a bit and would appreciate some help:

4 triggers in map (a,b,c and d) if the player needs to go through the triggers in this order d-c-b-a.
Each time the player goes to a wrong trigger in the sequence a “wrong” sound is heard, however if they go through the right trigger a “right” sound is heard.

I’m really struggling with this, so help would be both massively appreciated and needed
