No worries ,as long as I can help you, it’s all good. First of all, I see there are some nodes in your blueprint that aren’t set up correctly
You should have it like this
then if you dont want to have an interface you can set the code like that
on branch false and on cast fail conect the is valid node and at the end you have to set the current Interact(It should look like the one above)
you dont need this code in the player controller, so you can delete it
And for the button code, if I understood correctly what you’re trying to do, try this. You don’t need so many Branch nodes or the Sequence , a FlipFlop should be enough
Let me know if it works!
