Is there any chance your door is starting at 0,0,0 in the world? That’s seems like a very odd thing to do, adding actor location to actor location. Why not add a manual offset for your test? Like 10,0,0. No need to rotate your level or anything.
When you say “I created my vector graph for that direction” I am not sure what you mean. I don’t see any manual vector orientation anywhere in your blueprint, it’s adding its own location to itself which is strange. I’ll have to check out the tutorial to make sure it really suggests that.
