applyForceToPoint()

[li haoran]

Hello everyone!
I want to use the applyForceToPoint() function in the OpenSim::Force class. First I override the virtual functions clone() and getConcreteClassName() in the Force class. However, when I instantiate the object, the program reports an error saying that clone() and getConcreteClassName() are not overridden. Here is the partial code:

Code: Select all

class TugOfWarAddForce :public OpenSim::Force {
	OpenSim_DECLARE_ABSTRACT_OBJECT(TugOfWarAddForce, OpenSim::Force);
public:
	Object * clone()
	{}
	const std::string& getConcreteClassName()
	{}
	...
};
int main()
{
....
TugOfWarAddForce MyForce = new TugOfWarAddForce();
...
}

OpenSim::Force is an abstract class and thus cannot be instantiated. Perhaps you can use a class that derives from Force (see the inheritance diagram here: https://simtk.org/api_docs/opensim/api_ ... Force.html). There may also be some examples you could look at, depending on what you're trying to do.
