newbie questions? camera at the back of the charachter

hi first of all thanks for helping and sorry for my newbie questions…(python)

how can i set camera position at the back of my charachter?(third person shooter view)
just like “roaming raph” but it must be always at charachters back.

is there any world builder for panda 3d?is there any easy way to put 3d objects on the land where that we want?

camera is just an object like every thing else.
Reparent the camera to your character. Move camera backwards down the -Y axis.
