We will use this to trace from the player's location to 255 units in front of the character. If anything collides with the trace, we will face the pawn to the right based on the pawn's rotation. This simple check will be enough to make our bot run along the walls indefinitely; so, perform the following steps:
Pull the Return Value pin from GetActorLocation and drop it. Then, search for Vector + Vector.
We now need to select Get Controlled Pawn and pull Get Actor Forward Vector from it. This contains vector information going in the direction that is in front of our pawn.
So we will multiply Return Value by 255. This is the vector we want to add to the actor's location. This results in adding 255 units in the direction ahead of the pawn's current location.
Now, we need to take the results of the addition of the End pin for the LineTraceByChannel node. This will trace directly in front of our pawn:
Pull from the Vector + Vector node again, and this time we will plug it into the Dest pin for...
