Basic group effects question

jjas7

I'm still learning...

I want to have this effect apply to all groups all the time. Do I use a while statement?

on init

make_perfview
set_script_title("FX")
set_ui_height_px(350)
  declare const $SK_SLOT := 0
  declare const $FX := -1
  declare const $GROUP := 0
  declare ui_knob $RotatorKnob (0,1000000,1)
  set_knob_unit($RotatorKnob,$KNOB_UNIT_PERCENT)
  set_knob_defval($RotatorKnob,500000)
  make_persistent($RotatorKnob)
  set_knob_label($RotatorKnob,get_engine_par_disp($ENGINE_PAR_RT_SPEED,$GROUP,$SK_SLOT,$FX))
end on

on ui_control ($RotatorKnob)
  set_engine_par($ENGINE_PAR_RT_SPEED,$RotatorKnob,$GROUP,$SK_SLOT,$FX)
  set_knob_label($RotatorKnob,get_engine_par_disp($ENGINE_PAR_RT_SPEED,$GROUP,$SK_SLOT,$FX))
end on

Exactly.

on init

make_perfview
set_script_title("FX")
set_ui_height_px(350)
  declare const $SK_SLOT := 0
  declare const $FX := -1
  declare const $GROUP := 0

    declare $i := 0 { a variable to count each while loop }
    declare const $MAX_GROUPS := 11 { the absolute number of groups }

  declare ui_knob $RotatorKnob (0,1000000,1)
  set_knob_unit($RotatorKnob,$KNOB_UNIT_PERCENT)
  set_knob_defval($RotatorKnob,500000)
  make_persistent($RotatorKnob)
  set_knob_label($RotatorKnob,get_engine_par_disp($ENGINE_PAR_RT_SPEED,$GROUP,$SK_SLOT,$FX))
end on

on ui_control ($RotatorKnob)
  $i := 0
  while ($i < $MAX_GROUPS)
    set_engine_par($ENGINE_PAR_RT_SPEED,$RotatorKnob, $i ,$SK_SLOT,$FX)
    inc($i)
  end while
  { the above loop will set groups from 0 to 10. it may seem confusing because MAX_GROUPS = 10
    but remember that group IDs are zero based, so if you have 11 groups and want to
    change the settings in all groups, you will be setting engine parameters for groups 0 to 10 }

  set_knob_label($RotatorKnob,get_engine_par_disp($ENGINE_PAR_RT_SPEED,$GROUP,$SK_SLOT,$FX))
end on

from the above you can derive further ideas.

Thank you Gablux!

Actually, I received an error. Any idea why?

@Gablux Is there something missing in that line of code? Thanks!

Gablux

It seems there is a strange character after the closing parenthesis on that line, check that. It should be empty after the parenthesis close, just a return carrier to the next line

It was some mysterious scripting program error. It works now. Thank you so much @Gablux!
