I already made an IA Interact with an E key. I also got it to work to open and closing Doors. Now I wanted to make my inventory system and followed every step from the Tutorial of Ryan Laley from his Inventory System Tutorial. I’m now by Part 13 from his Tutorial.
But now I have the Problem that the “E” Key is only working for picking up Items but not anymore for opening / closing doors. I also tried to ask ChatGPT but he is talking non-sense and wants me to rebuild like everything from that what I’ve done so far so he is definitely no solution. I’m pretty new to all this developing stuff and started to learn the UE with ChatGPT.
I’m working on UE 5.7 and only with Blueprints. I can also post some Screenshots of my FirstPersonCharacter BP and my Inventory System and all that stuff if it would be helpful. But I’d really appreciate some help for how I can make it work to open/close doors AND picking up Items with the “E” Key since I need the Input Key for several things like also for interacting with NPC’s and so on.
You can check the thread below, where I used to have am issue with the door opening and o fi ally solved it, it contains a big part of my code that you can use and help yourself.
Hey there @McTeppichTV! I would recommend learning about Blueprint Interfaces. They are the most effective way to cleanly manage contextual interactions like this.
This post from Clockwork sums up the resources I usually recommend plus one more that combines both:

This is my “E” Event Interact for the Pickup. If the “Event Interact” is connected then the Pickup system doesn’t work. Only if I connect the “InputAction Interact” but then the doors aren’t working anymore.
It only fires when I connect the “InputAction Interact” from the pin “pressed” with the Exc. from “Get”. While “Event Interact” is connected it doesn’t fire.
Actually I’m writing a SP Game but I didn’t found any good tutorials for an SP Inventory System. The most Tutorials are just showing very simple Inventory Systems or the Videos are like 2h on Yt. So I just built it like Ryan Laley showed it in his Tutorials. Idk if it somehow impacts the whole Coding and writing when I make a Inventory System for the MP but actually doing a SP game.
It’s picking the correct actor. My problem is just that I can’t interact with them. I made a few tests earlier with ChatGPT and the problem was that it doesn’t recognize my Inventory System. It’s recognize the Actors and all that stuff but not my Inventory System.
I don’t think you can do a ‘get component by class’ on the player character? Not sure without testing it, but I think only your player type has that component.
You can check ( with a print of course ), if it finds that component.
If not, you either need to cast to your player type, or use an interface to get a reference to the component.
Is that a generic player character parameter, or already your player type?
It finds the Component. It is a generic player character. The standard one from the First Person Level from UE. I didn’t made my own one yet if it is that what you mean.
I also tried to cast it with “Get player character” and connect the “Get Player Character” node with “Get Component by Class” and still the same result.
I now added the Set and now it’s working. Such a simple solution omg. I really was struggling with this like for 2 Days… Now I can pickup the Flashlight and it goes into the Inventory AND I can open / close the doors. Omg I really thank you and appreciate your help and your patience. Really, thank you.
