Another thing: the Playmaker MOUSELOOK actions have the vertical axis inverted, and no option to have it opposite, it would be nice to have this option
Another action you could add to Playmaker is something universal like this:
Move forward - KEY
Move backward - KEY
Strafe left - KEY
Strafe right - KEY
Speed - NUMBER
Power - NUMBER
Move along - WORLD-SELF
So that any person can associate this action to any object in the scene (probably a camera, but it can serve many more functions) and have it move along X,Z in an easy way.
SPEED is a straight change to the position vector of the affected object, POWER is an applied force to the vector, so that it's coherent with physics in the scene.
This would make a flying camera very easy to make.
Maybe you could take straight away the script I posted and modify as an action of Playmaker and call it Mouselook3
Oh and expose the movement speed of course!
But make it time dependent and not framerate dependent!
