Op_create_object & Registerobject()

by Lateral Punk · in Torque Game Engine · 11/14/2006 (8:25 pm) · 2 replies

So I fell upon this strange bug where the callback to a guictrl::onAdd to script wasn't working for my PlayGui. Basically PlayGui.gui is exec'd during startup, but it seems that inside of

const char *CodeBlock::exec(U32 ip, const char *functionName, Namespace *thisNamespace, U32 argc, const char **argv, bool noCalls, StringTableEntry packageName, S32 setFrame)

under the case OP_CREATE_OBJECT, a call to currentNewObject->registerObject() is missing. And as a result, onAdd is not being called.

Am I to understand that OP_CREATE_OBJECT is called for .gui instantiated objects & OP_ADD_OBJECT is used for .cs instantiated ones? I would think we want registerObject() to be called for .gui scripts too no?

Am i missing something?

No, you are way off base.

Regardless of where in script you create an object, OP_CREATE_OBJECT does the new, then fields, other objects, etc are set with seperate opcodes, then OP_ADD_OBJECT is called to actually register it.

This is the correct way to do it and you will cause big problems by registering the object in OP_CREATE_OBJECT.

Hey Tom,
thanks for the response. Can you explain then why a script callback to Playgui::onAdd(%this) does not happen then? Try putting that script funciton into your project, and put an echo statement, let me know if you see the echo.
