- The correct title of this article is return. The initial letter is shown capitalized due to technical restrictions.
return value;
return value;| • type | value | – | value or variable to be returned by the function, the type must be the same as that to be returned by the function. |
Used to return execution to the previous scope along with a value.
Functions
- Exits the function and continues script execution in the previous scope.
Events
- Causes the script to crash. Events cannot return a value. Use the next form of this keyword instead.
return;
Used to prematurely return execution to the previous scope before reaching the end of the function/event. You do not need to use this at the end of an event or function, as it is assumed by the compiler.
Functions
- Exits the function and continues script execution in the previous scope.
Events
- Exits the event and removes it from the event queue. If there is another event in the queue, that event is triggered.
Caveats
- There is a bug in the compiler and it will let you return a value with events, which when encountered at runtime will cause the script to crash.
- Do not try to return a value in the event scope if you do not wish your script to crash.
Examples

llOwnerSay("Goodbye");
