Description
- Description:
- Breaks the code execution out of scope {} named name. nil is returned. Scope name can be assigned using scopeName command.
Since Arma 3 v1.47, breakOut can be used to return a value. It is the closest SQF comes to having "return"-like operation.

- Program Flow
Syntax
- Syntax:
- breakOut name
- Parameters:
- name: String - name of the scope (previously set with scopeName)
- Return Value:
- Nothing
Alternative Syntax
- Syntax:
- value breakOut name Template:since
- Parameters:
- value: Anything - a value to return
- name: String - name of the scope (previously set with scopeName)
- Return Value:
- Anything
Examples
- Example 1:
scopeName "main"; while {true} do { scopeName "loop1"; while {true} do { scopeName "loop2"; if (condition1) then {breakTo "main"}; // Breaks all scopes and return to "main" if (condition2) then {breakOut "loop2"}; // Breaks scope named "loop2" sleep 1; }; sleep 1; };- Example 2:
call { scopeName "main"; call { 123 breakOut "main" }; 345 }; // call returns 123

breakOut can still be used if multiple scopes share identical names. It will simply break out of the nearest scope that matches the name parameter you've used. For example:
call { scopeName "Main"; //Parent Main call { scopeName "Main"; //Child Main "String" breakOut "Main"; //Will break out of child main and return "String" to parent main }; };Therefore you are able to consistently reuse scope names such as "Main", "Child", "Primary", "Secondary", etc throughout functions without worrying about having to ensure you create unique names for each scope.
