So, I’m tring to make the default projectile stick only to a certain type of wall (wich is an actor) and for that I thougt about using a bolean and a branch where the wall checks (on overlap with a collision box I placed around it) if it is the projectile and sets the variable to true. Now, I placed a branch in the projectile blueprint that, if true, it stops the movement and if false i is destroyed, but I can’t get to connect the two bolean I created at the wall blueprint at the projectile blueprint as the target for the branch.
