How can I make tier rewards?
Specifically what I want to do is make first, second, and third place rewards, so for example, first place is when you collect up to 8, or all 10 points, second place 5 to 7, and third is 2 to 4, and anything under that you won't get a reward. I've tried using a calculator, and an X/or gate, but it didn't work.
A couple of ways, you were on the right path with calculators.
Use < & > Calculators to check if the value is above, below or between 2 values,
> 7 for 1st, so 8 or above the calculator = True,
< 2 for no reward, so 1 or below the calculator = True
For the between check you would use 2 calculators in to a & Gate, so,
< 8 and > 4 calculators to & Gate, 5 to 7 the & Gate = True
< 5 and > 1 calculators to & Gate, 2 to 4 the & Gate = True
Another option is to use a selector with Or Gates, put your value minus 1 in to the active port of the selector, then connect the appropriate outputs to or gates.
