GameThirsty, yes exactly, you'd set the position of some player positions head. An easy way to do it would be to use the custom movement plugin and layout a map in the layout editor. perhaps make a topic in the how do i section on the forum instead of posting here, so people wont have to go through 40 pages to find out how to do it. you'd want to move the player at the planar angle of the camera when the forward/backwards keys are pressed, and 90 degrees to the planar angle of the camera when the left/right keys are pressed. It'd probably be easiest to make the X-Y plane your floor.
Thank you for the help, I appreciate it greatly.
I am still not fully understanding how you mean to implement this, so I will recap what I think you mean.
To make an easy way to move the camera's position around the 3d world is to reference the players head camera to a sprite in a 2d plane. Give that sprite a custom movement behavior, and reference the sprite to make adjustments to the camera?
I will indeed be making a How to? Post here soon, I just want to get more information about it so I can make an example for everyone to use someday.
