That’s pretty close yes.
Think of it as placing a row of cubes side by side… each cube is what I am spawning. But in order to know where on the X axis I should spawn the next one (so they are exactly the same distance apart), I need to know the size of the BoxCollision component on said Blueprint Cube.
Case in point…
In the editor I’ve set this to be 100x100x100, but I don’t want to hard code those values into the nodes that are spawning them, because if I wanted to change the size of the Blueprint Cube later on, this would break. So, by extracting this information from the Blueprint - before - I spawn them, I can then determine exactly where they should be placed and there’s no hard coded magic numbers.
I’m pleased you’re getting something out of this though!
