Re: Smoothly rotating to another angle on pano nodes

[James C. W. <jfc...@ya...>]

Sorry for the late reply; holidays and all that. 
 
Thanks for the clarifaction. One problem that I've discovered with the "check if current direction ~ target direction and then angle the camera to precisly equal the target" is that if I pan myself while the program is running, the program loses track of where it's going, and hits the 80 EL pan limit, slowely spinning on the vertical access. Obviously, to make any of this effective the panorama must be frozen from player control. But since there's not any way to do that yet, I need to use the one that won't hit a dead end, and right now that's the version that checks how many times the function has run...Any suggestions?
 
Thanks,
  James

You don't need to "contact" the local variables, you pass the ones you 
need to set from outside as arguments. From inside, they are treated 
indentically to local variables. Like this:

function autoPan(tarAZ, tarEL, time)
   local rate = 0.025
   local iterCount = time/rate
   --...
   pipmak.schedule(
     rate,
     function()
       --do something involving tarAZ, tarEL, time, rate, iterCount, ...
     end
   )
end

and then you call it as

autoPan(270, 4, 1)
