getGameObject

API -

function test()
    local id = get('objectId');
    local app = getApp();
    local ob = app.getGameObject(id);
end
objectId = '';
return function()
    local app = getApp();
    local myObject = app.createGameObject(); --objects can be used for adding images
    objectId = myObject.id;
    async('test');
end

This is how you get objects to be shared between sub coroutines.
