Description

The instance part of the PythonScriptComponent. Allows for running a python script inside a NAP application. The python script has to implement a class with the name of the ClassName property. The class should implement:

• A constructor that takes the entity instance as an argument
• An update method that takes the total elapsed time and the delta time as float arguments.
• A destroy method that is called on destruction of the component that does not take any arguments.

Member Function Documentation

call()

bool call	(	const std::string &	identifier,
		utility::ErrorState &	errorState,
		Args &&...	args
	)

Tries to call a method in the python script with the specified number of input arguments. The identifier is the name of the python method to call. If the call fails the error will be logged in errorState.

Parameters

identifier	python method to call
errorState	contains the error if the call fails
args	variable number of input arguments.

Returns

if the call succeeded

get()

bool get	(	const std::string &	identifier,
		utility::ErrorState &	errorState,
		ReturnType &	returnValue,
		Args &&...	args
	)

Tries to call a method that returns a value in the python script with the specified number of input arguments. The return value will be stored in returnValue, the identifier is the name of the python method to call. If the call fails the error will be logged in errorState.

Parameters

identifier	python method to call.
errorState	contains the error if the call fails.
returnValue	the populated return value
args	variable number of input arguments.

Returns

if the call succeeded.

init()

bool init ( utility::ErrorState &  errorState )

overridevirtual

Initializes this component based on it's resource.

Parameters

errorState

contains the error when initialization fails.

Returns

if initialization succeeded.

Reimplemented from ComponentInstance.

update()

virtual void update ( double  deltaTime )

overridevirtual

Update this component

Parameters

deltaTime

the time in between cooks in seconds
