Hey again @BaBuuuuuu!
So you can get rid of that “Cast to Planet” node because planet is set, you can just attach it to the “Target” node. That’s what the “NOTE” on the cast is trying to tell you- it’ll save you a small amount of processing power.
Also, have you tried it this way?
As far as the operations, no, they shouldn’t be looped, you should specify what array element, and what value, then subtract the value from the previous value, set members of struct, then set struct. No loop!
