Hello,

Please note that you can use `FMath::RandRange` function to get a random number in custom range:

```
static int32 RandRange
(
    int32 Min,
    int32 Max
)

```

However, it is also possible to move the actor instantly to the specified location with `AActor::SetActorLocation` function:

```
bool SetActorLocation
(
    const FVector & NewLocation,
    bool bSweep,
    FHitResult * OutSweepHitResult
)

```

For more complex movement logic you can use **AI Controlled Pawn**.

In Unreal Engine 4, AI functionality is implemented with the help of **Behavior Tree** object. In particular, it has **Move To** function:

With the help of **Get Random Reachable Point in Radius** node, you can get the TartgetPoint for Move To function:
