hello,
you can add an expression to you the knobChanged of your node, like:
set cut_paste_input [stack 0]
version 7.0 v5
push $cut_paste_input
NoOp {
name NoOp1
knobChanged
"\nn=nuke.thisNode()\ntc=n\['tile_color']\nk=n\['color'].getValue()\nenumColor
= \[ \[1, 0, 0] ,\[0, 1, 0] ,\[0, 0, 1] ,\[1, 1, 0] ]\nr =
enumColor\[int(k)]\[0]\ng = enumColor\[int(k)]\[1]\nb =
enumColor\[int(k)]\[2]\nhexColour = int('%02x%02x%02x%02x' %
(r*255,g*255,b*255,1),16)\ntc.setValue(hexColour)\n"
tile_color 0xff000001
selected true
xpos -262
ypos -214
addUserKnob {20 User}
addUserKnob {4 color M {red green blue yellow ""}}
}
Hope this help!
