Comparing Variables

Script variables can be compared with literal values and other variables.

Variables Are Conditions

Variables and their comparison operators are naturally usable in conditions:

var alive = Var.Define("Is Alive", true);
On.Ready(If(alive).Then(Debug.Log("I live, therefore I must!")));

Operators Only

Comparisons can be performed entirely with operators < <= == != >= > ! ++ --.

Where To Use Comparisons

Variables and their comparison operators can be used as conditions whereever a ConditionBlock is accepted. For example:

• If(conditions).Then(actions)
• While(conditions).Do(actions)
• OR(conditions)
• AND(conditions)
• NOT(conditions)
• ...

Numerical Literal Comparison

This is true because compare's value is >= 0.1:

var compare = Var.Define("compare", 0.123456789);

On.Ready(If(compare >= 0.1)
        .Then(Debug.Log($"{compare.Value} is >= 0.1"))
        .Else(Debug.Log($"{compare.Value} is < 0.1"))
);

Numerical Variable Comparison

This is true because compare's value is not equal to other's value:

var compare = Var.Define("compare", 0.123456789);
var other = Var.Define("other", 0.1);

On.Ready(If(compare != other)
        .Then(Debug.Log($"{compare.Value} is != {other.Value}"))
        .Else(Debug.Log($"{compare.Value} is == {other.Value}"))
);

Numerical Truth

This is true because compare is a non-zero value:

var compare = Var.Define("compare", 0.001);

On.Ready(If(compare)
        .Then(Debug.Log($"{compare.Value} is true."))
        .Else(Debug.Log($"{compare.Value} is false.")),
);

Boolean Comparison

This example uses the ! negation operator and will execute the Else branch because truth is true.

var truth = Var.Define("a fact", true);

On.Ready(If(!truth)
        .Then(Debug.Log($"It's a fact. (True)"))
        .Else(Debug.Log($"It's an alternative fact!! (False)"))
);
