I'm not sure if this is a Unity or a Playmaker question, but here it is ... I am working on a simple prototype with Mario-like cannons, where every few seconds a new bullet prefab is created and shot across the screen. It seems that I have to have that prefab existing on the screen from the start to make the creation work though. I am wondering why this is, do I have to have a library of prefabs somewhere off the viewport in order to spawn them, or am I just overlooking something? Thanks for any advice on this.
