Get a Line Trace by Channel node and place it right after the Triggered pin of your IA. Then get the player character’s location with the Get Actor Location node and plug it into the Start pin of the line trace node. Then get the Get Actor Forward Vector node, multiply it with something like 200 using the multiplication node and add the actor’s location to it using the addition node, then plug the result into the End pin of the line trace node. Connect the Return Value of the line trace to the Condition pin of a Branch node and trigger your Add Movement Input nodes after it’s False pin.
Hope this helps!
