Hi, im sure you have solved it by now, but for the sake of there being at least one answer to your question:
Firstly I also am a noob.
I used this tutorial and found it very useful:
This is part4, where you learn to make melee and shooting attacks:
It is totally playmaker based.
As a noob I can summarize what he does as:
- Upon shoot button being pressed Creates a projectile object (which he saved as prefab previously) and adds velocity to this object in the correct direction.
-Upon spawning the object waits a set time before going to a state with 'destroy self' action.
-The object is tagged as projectile and enemies are FSMed to react on triggering the projectile tag.
Hope it helps someone.
