How can i make a interaction checker if the player has already interacted with A then he can interact with B?

Hi.

I want to create a system in Unreal Engine 5.4 where Interaction B checks whether Interaction A has already been triggered. If A is triggered then you can Interact with B than C…Its a very big help if somebody know this, I need it for a Horror game.

Can you provide more details? Interaction is a bit vague.

I think what you’re describing is similar to an interaction(hit or overlap event) with actors like in-game items or objects.

So, if you’re trying to make a system where interacting with A triggers B, and then interacting with B triggers C (and so on), there are several ways to approach this.

One approach could be using Delegates or Interfaces.

For example, when A is interacted with, you could use a Delegate event or an Interface function to activate B. Then, when B is interacted with, you trigger C in the same way, and so on.

There are other similar methods available, so I recommend checking documentation or searching for different approaches to see what best fits your needs.

So here is a blueprint and here I want that when this whole code runs after the delay there is a boolean variable. and the other blueprint looks the same like this but you should add that if that value is true, that is, the code has run, then the second one can run too
