Time for action – Dealing with Accessed None

To test this we need to purposely create an Accessed None, so let's do that now. We'll add a PostBeginPlay function to our BrokenActor.

1. Let's say we wanted to know the speed of a Projectile. We could add a variable and write a function like this in our PostBeginPlay:

   var Projectile MyProjectile;
   
   simulated function PostBeginPlay()
   {
       local float ProjectileSpeed;
   
       ProjectileSpeed = MyProjectile.Speed;
       `log("ProjectileSpeed:" @ ProjectileSpeed);
   }

2. Compile the code and run the game.

3. Exit the game and check the log:

   [0004.99] ScriptWarning: Accessed None 'P'
   	BrokenActor BrokenMap.TheWorld:PersistentLevel.BrokenActor_0
   	Function BrokenGame.BrokenActor:PostBeginPlay:004F
   [0004.99] ScriptLog: ProjectileSpeed: 0.0000

4. We're getting an Accessed None warning and the speed is logging as 0. That doesn't seem right, especially when the default for the Projectile class is 2000. Let's add another log to see what's going on:

   var Projectile MyProjectile;
   ...
