Defer in Verse

The defer expression delays the execution of code until the current scope exits. You can use the defer expression to handle cleanup tasks like resetting variables. Even when there is an early exit (such as return or break) from the current scope, the expressions in a defer block will run as long as defer is encountered before the exit.

The following code shows how to use defer to reset a variable to zero while still using that same variable as a return value. In this function, RoundScore is returned and the expressions in the defer block run immediately after.

This means you do not need to create a temporary variable to save the value of RoundScore before it gets reset to zero.

Verse

OnRoundEnd<public>() : void =
var ScoreThisRound : int = AddRoundScoreToTotalScore()
Print("Points scored this round: {ScoreThisRound}")
