How do you handle Booleans in Function parameters?

What's the best way to set a boolean in a Function call based on a variable value?

I can only see the "tick box" in the Function call dialog, which is only set by the programmer.

My current solution is a pair of if/else statements for each boolean:

• If sprite.boolean, call Function with the boolean tick-box ticked.
• Else call Function with the boolean tick-box unticked.

Now I'm thinking all the Booleans parameters should just be Numbers-but doesn't that defeat the purpose of having Boolean parameters at all?

Sorry, what I'm asking is how people deal with calling functions with boolean parameters when the boolean value isn't known.

Ideally boolean parameters wouldn't be a tick-box, but a value field, like string and number parameters are. That way you could use a variable value at runtime. Instead it's hard coded by the programmer.

E.g. Say function PrepareMeal has three booleans: eatsMeat, eatsVeg, eatsFish. And say the customer object has the same three boolean variables, but each customer has a different combination of true/false. You'd ideally pass through the customer objects' boolean values into a single function call, like "PrepareMeal(cust.eatsMeat,cust.eatsVeg,cust.eatsFish)", but functions don't accept variables for booleans.

So it seems like you either have two options:

1. Use a bunch of if/else statements calling the function with different combinations of booleans.

2. Use a Number parameter instead of a boolean, which can accept a variable.

Option 2 seems best, it just felt weird to not use boolean parameters for boolean variables.

So I thought I'd ask if there was a better approach to this before converting all these if/else groups to functions using numbers instead.
