Hello everybody.
Thanks again for your help^Mr.Grogger and for this awesome dialogue system.
For these who have isseus with the character who keep going to the last direction pressed, I have found a solution.
What you have to do is to simply set your charecter walkspeed to 0 on your Overlap event.
In your character blueprint, use your input key movement (Z, Right or whatever you press to move) and set your walkspeed to the original amount. It does the trick, you character won’t move by himself.
I think it’s pretty simple, but if you don’t understand this solution (Because my english is THAT bad), I can show you how I did. It’s not the best, I guess and it’s pretty messy and dumb, I suppose, but it works.
