I just tried AngelScript and I must admit that I like it, but there is one small problem :) Angelscript string str = "Some String"; void Update() { Print(str); } C++ engine->RegisterGlobalFunction("void Print(string &str)",asFUNCTION(PrintRef), asCALL_CDECL); Now everytime I execute it, i get an error which points me here: void asCScriptString::Release() { if( --refCount == 0 ) delete this; } if I change like this: string str = "Some String"; void Update() { Print(str+""); // Print(str plus "") } It works perfectly. Any ideas?
