That seems to work!
By adding this method to my node's class:
int PointSample::knob_changed(Knob* k)
{
knob("tile_color")->set_value(0x00ff0000);
return 1;
}
the node is now green straight-away upon creation. The only downside
is the moment you touch any knob, it's going to pop right back to
green again! haha, a great prank to be sure, but probably not the
ideal solution.
I wonder though, would it be possible to implement it in the build function?
Currently it is:
static Iop* build(Node *node)
{
return (new NukeWrapper(new PointSample(node)));
}
But could we do something like this? This will break, because I'm not
sure how to correctly code it.
static Iop* build(Node *node)
{
new NukeWrapper b = (new PointSample(node));
b.knob("tile_color")->set_value(0x00ff0000);
return b;
}
