New page

The '''do...until''' loop is a loop construct similar to the [[while loop]], but runs at least once.

==Syntax==
The syntax of the '''do...until''' loop is exactly what you would expect from its name:
'''do {'''
...
'''} until ('''''condition''''');'''
Note that UnrealScript doesn't "do...''while''", that means it loops until the condition is ''True''. (or while it is ''False'')

Like in any other loop construct you can use [[break]] and [[continue]] to exit the loop or jump to the next iteration.

==Quirks==
In [[Unreal Engine 1]] and [[Unreal Engine 2|2]] the compiler wasn't too strict when checking the '''until''' statement. You could omit it, essentially creating an infinite loop that had to be exited with the '''break''' or [[return]] statement. This "feature" was removed in [[Unreal Engine 3]].

A variation of the '''do...until''' loop is avaiable in all engine generations. Like with the other loop constructs, you can specify a single statement instead of the code block after the keyword '''do''':
'''do'''
''statement''''';'''
'''until ('''''condition''''');'''
Note that the statement needs to be terminated with a semicolon, similar to the non-block version of the [[If statement]] that requires a semicolon after its statement even if an '''else''' statement follows. It is strongly recommended to enclose even a single statement in curly braces to prevent potential misunderstandings and oversights.
