(To follow up on http://www.gamedev.net/topic/591814-funcdefs-to-member-functions/ and http://www.gamedev.net/topic/607706-lambda-functions/ and http://www.angelcode.com/angelscript/sdk/docs/manual/doc_adv_coroutine.html ...)

I'm wondering how to allow a script to spawn a coroutine where the function signature (of the function to call in the newly-spawned script context) is not fixed/known ahead of time (and provide those parameters).

Using the script funcdef syntax, a script can create a function handle to a function-signature that I can't anticipate ahead of time. I'd like the script to then be able to spawn a coroutine using that handle as the starting point, and provide whatever params that function needs.

Is there any precedent for doing this? Or is it best to limit the script-side spawning of coroutines to a function signature that takes no params, or predefined-ahead-of-time number/type of params?

Thank you.

That seems really elegant... I'll have to investigate (I'm not using the dictionary add_on quite yet)!

Thank you very much.

I've created a CScriptDictionary object in C++, filled it in with some elements, and called script with that param.. and was able to print out all the dictionary keys.

Is there any guidance in the documentation which would be helpful as to the type id to use for this CScriptDictionary signature?

void Set(const std::string &key, void *value, int typeId);

So far I used asTYPEID_SCRIPTOBJECT when passing an std::string& to a script string (registered with the add_on), and asTYPEID_APPOBJECT when passing a void* to an application object registered as a reference type with script. Is that correct? Would I use asTYPEID_OBJHANDLE in any situation?

Thank you very much.

I got the below working, but it appears that if the dictionary (that's passed to the coroutine) contains some application-defined value types, modifying the value type in the dictionary in the coroutine affects the dictionary that was passed into MyCoRoutine() once SpawnCoRoutine() returns.

Before I execute "MyCoRoutine" from C++, I probably have to manually create a 2nd CScriptDictionary instance, fill it in element-by-element (creating copies of application-registered value types), and pass that instance to MyCoRoutine?

void MyCoRoutine(dictionary @dict)
{
   ... do some processing as a co-routine
}
 
void main()
{
   dictionary values = {{'first', 1}, {'second', 2}, {'third', 3}, {'etc', 4}};
   SpawnCoRoutine(MyCoRoutine, values);
}
