Instead of 6 separate compares to 6, use for loop.
- make array of dices that has all reference to them, die 1croll die2croll …
- then make for each loop that goes trough that array
- then get correct reference from array and compare it
- index will be first die that has 6
And generally convert this logic to forloop, work more with arays. Make blueprint function library, create there some pure functions. All that helps with limiting clutter and spaghetti code (this name fits perfectly for blueprints).
