batch importer - hartsantler - 09-08-2018
I am trying to figure out how to batch import multiple obj and collada files when wings starts up.
I'm new to erlang, and taken a look at the code in: e3d_obj.erl, wings_console.erl, wings_start.erl, wpa.erl, wpc_collada.erl, and wings_plugin.erl.
So far i have this code, which loads my obj, but then fails to update the view or show it in the Wings UI. What am i missing?
Code:
{ok, E3DFile} = e3d_obj:import("/home/username/test.obj").
St0 = wpa:get_state().
wings_import:import(E3DFile, St0).https://github.com/dgud/wings/issues/298

I'm not expert, so maybe my suggestion can not to work.
Import will return the new #st{}, then maybe you just need to update it by send that information to the main geometry window who handle most the command messages:
Code:
...
St = wings_import:import(E3DFile, St0),
wings_wm:send_after_redraw(geom, {update_state,St}).RE: batch importer - hartsantler - 09-08-2018
actually i'm getting an error from `wings_import:import(E3dFile, wpa:get_state()).`
the error is:
Code:
** exception error: no function clause matching
gb_trees:get_1(wings_shape,nil) (gb_trees.erl, line 244)
in function wings_shape:new/3 (wings_shape.erl, line 64)

Did you already tried to print out the value of St0 in the line bellow?
St0 = wpa:get_state().
RE: batch importer - hartsantler - 09-08-2018
printing St0 gives this:
Code:

{0,nil},

Yeap, it's a invalid (null) #st{}
