Re: libseed-list Clutter.Animator.set_key - g_value_set_float: assertion `G_VALUE_HOLDS_FLOAT (value)' failed

["Alan Knowles" <alan akbkhome com>]

Try this..

var start_value = new GObject.Value(imports.gi.GObject.TYPE_FLOAT);
var end_value = new GObject.Value(imports.gi.GObject.TYPE_FLOAT);

start_value.set_float(200);
end_value.set_float( 300);

in your version, the start_value was set to a Javascript number, which gets converted to a DOUBLE type 

otherwise you could do:

animator.set_key(rec, "x", 2, a, [ imports.gi.GObject.TYPE_FLOAT,  start_value]);
animator.set_key(rec, "x", 2, b,  [ imports.gi.GObject.TYPE_FLOAT,  end_value] );
