Conditional Statements (if)

The if statement in Femscript is used to execute code based on a condition. It provides a way to handle decision-making logic in your scripts. Unlike in some other languages, the condition in Femscript is not just a boolean expression—it is a block of code. The value of the condition is determined by the result of the last operation in the block.

An optional else block can be used to execute code when the condition evaluates to false.

Syntax

Conditionals in Femscript use the following structure:

1
2
3
4
5
if { condition } {
    # Code to execute if condition is true
} else {
    # Code to execute if condition is false (optional)
}

The condition is a block enclosed in {} that can contain multiple operations. The value of the condition is determined by the last operation inside the block.

Examples

Basic Example

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
person = {
    name = "Joe";
    age = 17;

    if { age >= 18 } {
        message = format("{name} is an adult.");
    } else {
        message = format("{name} is a minor.");
    }
};

print(person.message); # Outputs: Joe is a minor.

In this example:

  1. The condition { age >= 18 } evaluates to false.
  2. The else block is executed.

Complex Conditions

Condition can perform multiple operations:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
x = 35;
y = 34;

if {
    total = x + y;
    total > 10 # This line is returned as the condition's value
} {
    result = format("{total} is greater than 10.");
} else {
    result = format("{total} is 10 or less.");
}

print(total); # Outputs: 69
print(result); # Outputs: 69 is greater than 10.

Here:

  1. The total variable is calculated within the condition block.
  2. The result of the block (total > 10) determines which branch of the if statement is executed.
