If

With the if expression, you can make decisions that change the flow of the program. As with other programming languages, the Verse if expression supports conditional execution, but in Verse, the conditions use success and failure to drive the decision.

For example, you can write code that defines the fall height a player can drop before taking damage.

|  | var PlayerFallHeight : float = CalculatePlayerFallHeight() |
| --- | --- |
|  |  |
|  | # Players take damage if they fall more than 3 meters |
|  | if (PlayerFallHeight > 3.0): |
|  | DealDamage() |
|  |  |
|  | # Reset the player’s fall height |
|  | ZeroPlayerFallHeight() |

In this example, if PlayerFallHeight is greater than three meters, then the condition succeeds and DealDamage() is executed before the player’s fall height is reset. Otherwise, the condition fails so the player doesn’t take any damage but the player’s fall height is reset.
