How to calculate and print the distance between two objects using BluePrints?
Simplest way between two Actors is to use the “Get Distance To” node, then use the “Print String” node.
Or that! 
While the DistanceTo node is great for two actors, this method is good for any two points so knowing this math is a must in my opinion. Some day you’ll be curious how far you are from a hit test location or such and this will come in very handy.
