Hi Everyone, Making a mod with a few others that has walkwalking - the actual physical walking along walls part has been implemented.
Basically it uses the normal of the surface you are walking on and the viewing direction of the player to construct the correct 'right' and 'forward' unit vectors, so that the players movement is constrained to the surface (using the cross product). The problem I am having now is that I want to change the camera angle to face the "forward" direction of the surface. I have hooked up the server-client code so that I can directly change the camera angle however my vector cross product calculations screw up because I am now changing the camera viewing angle and then using it to make a calculation which changes it again - e.g. circular madness. Thus I am sure it is possible because you see it done all of the time - but is there a way to construct at least one right angled vector from just one vector? The cross product requires 2 vectors, so I played with arbitrary vectors and rotations to the original direction of the normal to the surface - however I get problems where one wall's normal will eventually be co-linear to the vector I have chosen (which results in a zero vector). So I am not sure I really explained the problem all that well - I can go into more detail if anyone doesn't understand.
