Hello,

I am trying to implement different views for a spacecraft simulator using a LUA script. I managed to create 3 working views all with the same distance between spacecraft and observer. When I tried to create a 4th view with a larger distance it became a mess. I realized that if I centerorbit or lock after a chase/follow the gotodistance command is not applied. The thing is that everything works if I chose manually first one command and then the other one. I tried then to put waits and while(obs:travelling()) to force the same effect but it does not work. It is really strange. Maybe a command cancels another one.

Basically what I want each view to do is to set a chase/synchronous/follow, then maybe lock and centerorbit, and finally increase the observer distance to certain amount. Could you help me please?

this is one of the views that I have. It does not set the distance:

        obs:chase(spacecraft)
        actual_travel = obs:travelling()
        while actual_travel do
          actual_travel = obs:travelling()
          wait(0.0)
        end
        obs:gotodistance(spacecraft, 0.1, 0.0)
        obs:lock(planet)
        obs:centerorbit(planet,0.0)

The gotodistance command only works if is the last one. So, if I remove the last two lines and after setting this view I set another one with only this two commands, it works.

Thank you in advance.
