parent-child

I'm attempting to understand how to group / link child meshes to a parent. I want to be able to: drag the parent rotate child elements relative to the parent have parent rotation / translation do the right thing for children My only background in this is using LSL in Second Life to manipulate linked prims in an object. I am thinking I dont want to merge meshes, because I want to maintain control (hover, texture, rotation, scaling, etc) over each child. Any good tutorials on this out there? This is achieved with THREE.Object3D(), yes? thanks, Daniel The dragging will be a bit more tricky

I've been asking for this for a while. Can't believe there's not a single dev that wouldn't know the answer and I'm a little desperate In Sonata, I cannot make the url structure/pattern /parent/ID/child/list work. Went thru the very, rather poor, 4.6. CREATE CHILD ADMINS section in sonata docs, found only a few examples online and I can't make it work Can someone explain step by step how to set such structure up? I will use the example provided by Sonata in my explanation, a basic Post/Comment relation. You must have a parent/child link (oneTomany / manyToOne relation) between your entities

I currently have an operation in a module that is blocking, so I'm looking at making this into a child process that I fork instead. If I want to do that, then I of course need to modify the architecture of my module. The module requires that a dependency is injected by calling the module as a function, passing in the dependency, like so: var dependency = { name: "Bob" } require('worker')(dependency) Then in my worker module: module.exports = function (dependency) { // Outputs { name: "Bob" } console.log(dependency) } How can I turn this example into a child process being forked? When using

I need to get a list of attribute values from child elements in Python. It's easiest to explain with an example. Given some XML like this: <elements> <parent name="CategoryA"> <child value="a1"/> <child value="a2"/> <child value="a3"/> </parent> <parent name="CategoryB"> <child value="b1"/> <child value="b2"/> <child value="b3"/> </parent> </elements> I want to be able to do something like: >>> getValues("CategoryA") ['a1', 'a2', 'a3'] >>> getValues("CategoryB") ['b1', 'b2', 'b3'] It looks like a job for XPath but I'm open to all recommendations. I'd also like to hear about your favourite

I am getting the following error in C++: error C2614: 'ChildClass' : illegal member initialization: 'var1' is not a base or member Class Base { protected: int var1; public: Base() { var1=0; } } class Child : public Base { int chld; public: Child() : var1(0) { chld=1; } } I feel what I have done is as per OO protocol. Here var1 is a data member of Base class with protected as the access specifier. So It can be inherited and it would become private in child. Don't understand why am I getting the error? It doesn't work for the exact reason the error message provides you: you can only use

I've found the issue with using primitive type as an object @Id for JPA in conjunction with Spring Data JPA. I have parent/child relationship with Cascade.ALL on the parent side, and child has PK which at the same time is also parent's FK. class Parent { @Id private long id; @OneToOne(mappedBy = "parent", cascade = ALL) private Child child; } class Child { @Id @OneToOne private Parent parent; } So, when I run: ... Parent parent = new Parent(); Child child = new Child(parent); parent.setChild(child); em.persist(parent) ... everything works fine. But I used Spring Data JPA to persist the entity,
