animations not playing when model is added to render_2d

C++ coding using Panda3D

loading a (model + animation) and setting it’s parent to be other than _render causes animations not to play. for example if the parent is render_2d the animations will not play.

this works fine:

// Load panda
NodePath pandaActor = window->load_model(window->get_render(), "/c/Panda3D-1.7.2/models/panda.egg");
pandaActor.set_pos(init_pos.get_x(), init_pos.get_y(), init_pos.get_z());
// Load the walk animation
window->load_model(pandaActor, "/c/Panda3D-1.7.2/models/panda-walk");
window->loop_animations(0);

this doesn’t work:

// Load panda
NodePath pandaActor = window->load_model(window->get_render_2d(), "/c/Panda3D-1.7.2/models/panda.egg");
pandaActor.set_pos(init_pos.get_x(), init_pos.get_y(), init_pos.get_z());
// Load the walk animation
window->load_model(pandaActor, "/c/Panda3D-1.7.2/models/panda-walk");
window->loop_animations(0);

i found that the reason is the following call:

window->loop_animations(0);

it calls:

auto_bind(get_render().node(), _anim_controls, hierarchy_match_flags);

and so only nodes under the _render nodepath will have their animations bound. probably the method: loop_animations() should be overloaded to accept any node path.

any other solutions?

A fine idea. However, loop_animations() is just intended to be a simple convenience method. All it does is make two function calls, after all, which you can just as easily call directly, in your slightly unusual case.
