Update: 18/01/18
The IDLE state prototype is currectly working, not all of the glowy nice shapes have been added yet but that will happen later.
The effect has some of the needed setup to change to the CHARGING state. I've used blueprint timelines to animate the orbs movement, because of this I can then alter the speed etc from within blueprint based on a state I set.

There is currently an issue on the looping, they start and stop abruptly with no obvious reason why. I will hopefully solve this soon, in the meantime on to figuring out how to change the colour of particle systems within blueprint!
