So I have a blueprint which will fire when the enemy AI Senses the player. The problem is he is a melee character and I only want him to attack when he is within melee range of the player character. Still fairly new to blueprints so any help would be appreciated. Here’s what I have so far.

if((ActorLocation - EnemyLocation).Size() \<= MeleeRange)

```
{

     //execute your code

}

```

make these nodes:

1. Vector - Vector (GetActorLocation - TargetCharacter-\>GetActorLocation)
2. GetVectorLenght (or Size or however it is called (long time since I did BP, I do c++ now))
3. \<= (floats)
4. Branch

Put one into 2

Put 2 into 3, with your melee range second

And execute your melee logic on the true branch

Hope this helps
