Create a template object in C++ based on the template of another object

[hugtalbot]

In a base class like ODESolver.h, I want to create a GravityForceField in the create() function where DataType is the type of the MO of the context.
Any idea on how to proceed?

Have a look on the sofa::core::ObjectFactory::CreateObject function, and see if it fits your need

If recommand using simpleapi for that.

BaseObject::SPtr addBoxROI(BaseObject::SPtr target)
{   
       Node::SPtr node = dynamic_cast<Node*>(target->getContext());
       return createObject(node, "BoxROI", {{"template", target->getTemplateName()}} );
}
