Key Pressing and Entity Spawning

[bieux]

So, I was messing around with Abigail when I had the idea to make her spawn or despawn by the press of a button. I had no clue on how to do the key pressing and the spawning/despawning stuff, specially how I would make it despawn after pressing the button for the second time. Does anyone know how could this be done in a simple way? I deeply appreciate the help.

The code in this post works for the "press key" thing. You only have to add your code to spawn sth:
