Hi All

First I want to move the variable mover form 50 to 0 in between clock values of
0 and 5.
Then as the clock values increase from 5 to 10 I want mover to go from 0 to 50.
Then as the clock values increase from 10 to 15 I want mover to go from 50 to
100.
Then as the clock values increase from 15 to 20 I want mover to go from 100 to
50.

I have found the section
3.2.1.2 Internal Animation Loop

 For new scenes, we recommend you do not change the Initial_Clock or Final_Clock
from their default 0.0 to 1.0 values. If you want the clock to vary over a
different range than the default 0.0 to 1.0, we recommend you handle this inside
your scene file as follows...
#declare Start    = 25.0;
#declare End      = 75.0;
#declare My_Clock = Start+(End-Start)*clock;
Then use My_Clock in the scene description. This keeps the critical values 25.0
and 75.0 in your .pov file.
I rename most of these so as not to interfere with pov internal values.



//----start code segment----
#switch(MyClock)
  #range(0,5)//centre to full left
    #local MinClock= 0;
    #local MaxClock= 5;
    #local MinMove = 50;
    #local MaxMove = 0;
  #break
  #range(5,10)//full left to center
    #local MinClock= 5;
    #local MaxClock= 10;
    #local MinMove = 0;
    #local MaxMove = 50;
  #break
  #range(10,15)//center to right
    #local MinClock= 10;
    #local MaxClock= 15;
    #local MinMove = 50;
    #local MaxMove = 100;
  #break
  #range(15,20)//right to center
    #local MinClock= 15;
    #local MaxClock= 20;
    #local MinMove = 100;
    #local MaxMove = 50;
  #break
  #else
    #error concat("MyClock=",str(MyClock,0,0),".\n")
#end

#local Mover=
(MinMove+(MaxMove-MinMove))*(MyClock/(MinClock+(MinClock-MaxClock)));;
//----end code segment----

I would like to leave the switch statement alone as this is the controlling
element and will allow for further development later. I trying to develop a
single equation to calc the output.

Any help would be appreciated and great fully received. Thank you.
