Basics of Writing Code 4 Practice Time in Verse

Return to your magic potion code from the last exercise. You will want to run the healing code when the player drinks a healing potion, and the damage code when they drink a damaging potion.

First You Write Some Code ...

1. Sounds like you'll have to answer a question about the type of potion, so you can create a new variable to keep track of that, a string called PotionType.

        var PotionType: string = "heal"
   

   var PotionType: string = "heal"

   Copy full snippet(1 line long)

2. Now you can ask if the variable PotionType is equal to another string. When you ask if PotionType is equal to "heal", the answer will be yes. The healing code would then run.

   |  |  |
   | --- | --- |
   |  | if (PotionType = "heal"): |
   |  | set PlayerHealth = PlayerHealth + PotionHealAmount |
   

   if (PotionType = "heal"): set PlayerHealth = PlayerHealth + PotionHealAmount

   Copy full snippet(2 lines long)

3. Now write a similar if expression for the damage code.

   |  |  |
   | --- | --- |
   |  | if (PotionType = "damage"): |
   |  | set PlayerHealth = PlayerHealth - PotionDamageAmount |
   

   if (PotionType = "damage"): set PlayerHealth = PlayerHealth - PotionDamageAmount
