Description: Decrements (decreases) tag by specified amount, percentage , tag value or script variable until OUTPLO (output low span) reached then resets counter to OUTPHI (output high span) minus the delta of the last increment above OutpLo. It carries over and difference between OutpLo and the last increment calculation. Repeats continuously. Similar to LOOPMINUS, but when OutpLo reached, next value is exactly is not necessarily equal to OutpHi. This makes for smother animation of rotation if the increment is not an even multiple of the output span.
Syntax: <SETVAL>tagname=%ROTATEMINUS arguementr
Arguments: number or tagname
Examples:
<SETVAL>counter=%ROTATEMINUS
1
# decrements tag named counter by 1
# until OutpLo
reached
# then resets
counter to OutpHi
# minus whatever
remainder there was in the
# decrement below
OutpLO. Repeats.
<SETVAL>tag2=%ROTATEMINUS 1%
#
decrements tag2 by 1 percent of output
# span until
OutpLO reached
# then resets
counter to OutpHI
# minus whatever
remainder there was in the
# decrement below
OutpHi. Repeats.
<SETVAL>tag2=%ROTATEMINUS
@tag1
#
decrements tag2 by value of tag1
# until OutpLO
reached
# then resets
counter to OutpHI
# minus whatever
remainder there was in the
# decrement below
OutpLO. Repeats.
