Our system has a function looks like this:

MyObject* getAnotherObject(std::function<int(int)> get_strategy);

This function need to be called from script side, but we prefer to allow get_strategy being implemented from script side. I immediately got some problems:

1, Is it ever possible to call a script function on the half way of native callback? Does AngelScript allow to do that?

2, How to obtain the running AngelScript context from the function wrapper side? I only find GetEngine() in asIScriptGeneric that give you corresponding engine, but don't know how to get context.

3, The C++ function probably should be registered as MyObject@+ getAnotherObject( CallbackFunc@ ), where the callback function probably looks like funcdef int CallbackFunc( int );. However, at the time C++ function is registered, the funcdef to callback function does not exist, as source code is compiled after C++ type registration. How should I solve this?

@WitchLord If I can ensure there is only one context for each engine, can I get the context from engine→RequestContext()?

What is the behavior of the context pooling implemented in CScriptEngine?

And do I need to fill the context callbacks, or just leave them blank?
