[SOLVED] Examples on Player.setUp or setModelview to "roll" the camera (psi angle)

[koshman86]

Hello, I'm having troubles with setting the camera "roll" rotation (like a spinning airplane), or (it's equivalent) setting arbitrary camera Up direction.

Are there any examples on it?

 

The problem is, I made a camera flying round the Earth, and I set direction of radius-vector as Up direction using PlayerSpectator.setUp(). Camera is moved by (camera)Node.setPosition(). At certain positions (e.g. 1000;0;1000), I get camera suddenly "reversing" backwards, and if I keep pressing "forward" it reverses again, and again, so moving like stairsteps (shifting slowly up or down). As I found, there appears some exchange of x<->z coordinates of camera. I tried to catch the change, and it seems to happen outside my code. When I remove setUp(), the "reversing" vanishes.

 

I also tried to use PlayerSpectator.setModelview() (seems to have no effect), and (camera)Node.setRotation() (only sets direction and fails to roll the camera).

Solved by replacing:

 

SetDirection()

SetUp()

 

to

 

SetUp()

SetDirection()

 

, the camera stopped "reversing".
