Develop a Probe plugin

[Vinh Nguyen]

Hello,

I am trying to write a probe plugin which calculates the muscle metabolic cost. My calculation has a small difference compared to the built-in Umberger2010MuscleMetabolicsProbe of OpenSim. I have my set up that works well for the plugin example tutorials. Now, with the same set up, I copy the code from Umberger2010MuscleMetabolicsProbe.h and Umberger2010MuscleMetabolicsProbe.cpp which are in OpenSim source code. Then,

1. Include: #include <string>
#include "osimPluginDLL.h"
#include <OpenSim\Simulation\Model\Probe.h>
#include <OpenSim\Simulation\Model\Model.h>
#include <OpenSim\Common\Object.h>

2. Replace all OSIMSIMULATION_API by OSIMPLUGIN_API

3. In RegisterTypes_osimPlugin.cpp, I have
Object::registerType(Umberger2010MusMetProbeNew() );
Object::registerType(Umberger2010MusMetProbeNew_MetabolicMuscleParameter());
Object::registerType(Umberger2010MusMetProbeNew_MetabolicMuscleParameterSet());

4. I have not implemented my calculation. Just want to test if it works.

When I build the solution, I get the errors:

Any help and advise would be great. Thank you in advance.

You need to define the move constructor and move assignment operator for Umberger2010MusMetProbeNew class, because they were not declared implicitly by the compiler.

Code: Select all

Umberger2010MusMetProbeNew(Umberger2010MusMetProbeNew &&) { ... };
Umberger2010MusMetProbeNew::operator=(Umberger2010MusMetProbeNew &&) {... return *this};

When you registered the new class you called (Object::registerType(Umberger2010MusMetProbeNew());) which creates an rvalue of type Umberger2010MusMetProbeNew and that is why the move operators are required.

Thank you, Dimitar.

I got it worked.
