Hi!

I try to implement passing delegates as arguments from script and call it from c++.

i use follow code to store script function -

void ScriptModuleCore::Network::SetDelegate(DelegateAS& delegateAS, asIScriptFunction* cb)
{
   asIScriptEngine* engine = ((ScriptMachine*)(core->Script()->Machine()))->Machine();
 
   if (delegateAS.callback)
   {
     delegateAS.callback->Release();
   }
 
   if (delegateAS.callbackObject)
   {
      engine->ReleaseScriptObject(delegateAS.callbackObject, delegateAS.callbackObjectType);
   }
 
   delegateAS.callback = 0;
   delegateAS.callbackObject = 0;
   delegateAS.callbackObjectType = 0;
 
   if( cb && cb->GetFuncType() == asFUNC_DELEGATE )
   {
      delegateAS.callbackObject     = cb->GetDelegateObject();
      delegateAS.callbackObjectType = cb->GetDelegateObjectType();
      delegateAS.callback           = cb->GetDelegateFunction();
 
      engine->AddRefScriptObject(delegateAS.callbackObject, delegateAS.callbackObjectType);
 
      delegateAS.callback->AddRef();

      cb->Release();
   }
   else
   {
      delegateAS.callback = cb;
   }
} 

follow code executes script function

asIScriptContext* ctx = GrabContext();
	
ctx->Prepare(script_func);			

ctx->SetObject(hack_callbackObject);

ctx->Execute();

All fine when we deal with just function. But if we pass delegate than we got assertion in AngelScript in follow function -

// internal
int asCScriptFunction::GetRefCount()
{
   asASSERT( funcType == asFUNC_DELEGATE );
 
   return externalRefCount.get();
}

Maybe i just doing something wrong when dealing with delegate from c++ or this is bug in AngelScript?

Hi!

Looks like problem is - i used delegateAS.callback = cb->GetDelegateFunction(); insteed i must store script function in manner i deal with just callback and i must rise reference count.

So now my function with storing scriptfunction looks like:

void ScriptModuleCore::Network::SetDelegate(DelegateAS& delegateAS, asIScriptFunction* cb)
{
	asIScriptEngine* engine = ((ScriptMachine*)(core->Script()->Machine()))->Machine();

	if (delegateAS.callback)
	{
		delegateAS.callback->Release();
	}

	delegateAS.callback = cb;

	if( cb && cb->GetFuncType() == asFUNC_DELEGATE )
	{
		delegateAS.callback->AddRef();
	}
} 

and now works perfect.

Thanks for help :)

I corrected code.
