Looks like the "point" you need to target should be related to the position of your mouse's cursor. I suspect you're doing a top-down manic pedestrian shooter where you control the shooter with keys and the direction of the projectiles with where your mouse is.
You must tell Playmaker/your game where the cursor is in your scene or screen view with a raycast of some sort.
Then, either directly use the coordinates or use a gizmo that automatically sticks to the projected cursor's coordinates and use that gizmo Game Object as a target.
