Hello I'm trying to register a simple C structure from an external engine and then I want to access one as a global from a script. Currently I have... scriptEngine->RegisterObjectType("CgVector2D", sizeof(CgVector2D), asOBJ_VALUE | asOBJ_POD | asOBJ_APP_CLASS ); scriptEngine->RegisterObjectProperty("CgVector2D", "float x", offsetof(CgVector2D, x) ); scriptEngine->RegisterObjectProperty("CgVector2D", "float y", offsetof(CgVector2D, y) ); scriptEngine->RegisterGlobalProperty("CgVector2D myGlobalVector", &myGlobalVector); Then in my script I do... myGlobalVector.x = 100; myGlobalVector.y = 100; When I've run the script there's no change in my global vector. I'm not sure about the offsetof() bit, does this work on structures? I check all the return values and nothing throws an error. On a side note I also tried to do... scriptEngine->RegisterGlobalProperty("float myGlobalVector.x", &myGlobalVector.x); scriptEngine->RegisterGlobalProperty("float myGlobalVector.y", &myGlobalVector.y); But it failed registering the Y as the name was already in use. Any ideas? Thanks Scott

Thanks for the reply.

I had checked the different test files and the examples but I must have missed something. I went back and put the code back in (I'd commented it out while carrying on with writing code) and now it works fine.

My gut feeling is I was inspecting the wrong variable in the debugger. It's all working now though. Thanks!
