Description

Description:
Breaks the code execution out of scope {} named name. nil is returned. Scope name can be assigned using scopeName command.
An unknown scopeName name will cause a `Generic error in expression` script error
An empty scopeName name will leave the current scope immediate



Since Arma 3 v1.47, breakOut can be used to return a value. It is the closest SQF comes to having "return"-like operation.
Groups:
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.
