[SOLVED] Compilation error while setValue to d_force in linearFF

[Noura]

Hello,

I’m creating a linear force field and facing some difficulties in setting values to its member data (for example in the d_force attribute).

Firstly, I declare a parameter “initForce” in my component header file:

typedef typename DataTypes::Coord::value_type Real;
Data<Real> initForce;

In the constructor of the component, I initialize it like this:

AwesomeComponent<DataTypes>::AwesomeComponent()
        : initForce(initData(&initForce, 0.0, "initForce", "initial applied stretch force to all points"))

Then, I create a linear force field:

forcefield::LinearForceField<defaulttype::Vec3dTypes> tmp_lff;
forcefield::LinearForceField<defaulttype::Vec3dTypes>::SPtr l_forceField;
l_forceField = sofa::core::objectmodel::BaseObject::create<forcefield::LinearForceField<defaulttype::Vec3dTypes>>(&tmp_lff, force_node->getContext(), &lff_objDiscr);

Now when I set the value to the force directly like this:

  
l_forceField->d_force.setValue(sofa::defaulttype::Vec3dTypes::Coord::value_type(1.0));

Everything is fine!

But, when I set the value using “initForce” parameter (which I read directly from the scene file)

l_forceField->d_force.setValue(initForce);

I got a compilation error:

...AwesomeComponent.inl:305: error: no matching member function for call to 'setValue'
    l_forceField->d_force.setValue(initForce);
    ~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~

Any hint how to pass the value through “initForce” parameter?

Thanks!

Solved!
Actually It should be simply :

l_forceField->d_force.setValue(initForce.getValue());
