Enums

Enums are a set of constants. Calling an enum outputs as a number. In the below, PowerupType.Wall will output as 0, PowerupType.DamageBoost outputs as 3.

enum PowerupType
{
    Wall,
    JumpBoost,
    SpeedBoost,
    DamageBoost
}

You can get a random enum value by casting.

PowerupType powerup = <PowerupType>RandomInteger(0, 3)

You can also store arbitrary values in enums (do note that this means you won't be able to cast integers to enums anymore):

enum DeathResponses {
   Annoyed = "Ouch, that hurt!",
   Disappointed = "Back to the drawing board..",
   Angry = "Now you've done it."
}

enum StatusFlags {
   Poisoned = 1,
   Frozen = 2,
   Stunned = 4,
   Confused = 8,
   Enraged = 16
}
