user defined data

hi guys

i want to be able to add my own data to objects within blender, export them and then load/parse them within the sio2 engine. apparently tutorial 9 contains these details but i have been through it thoroughly and can't find anything. is it there and i am just very tired and need to try again tomorrow or was it left out for some reason? if so can someone possibly give me a place to start looking into it myself

thanks

User defined variables go in the Logic panel. Just click Add Property.

and check tutorial09 to see how you can retrieve them back...

I have been through tutorial 9 and managed to make a start. Within the custom_parser i use the void pointer 'userdata' to store a user defined property to be used later. this works fine.

unsigned char custom_parser( char *_root, char *_tok, char *_val )
{
....
float *temp;
sio2StringScanf( _val, "%f", temp);
sio2->_SIO2object->userdata = temp;
....
}

however when i come to read this value out of 'userdata' later on the value has changed is no longer correct.

am i right in thinking 'userdata' can be used in this way ? or does anyone have any ideas what is causing the value of 'userdata' to change?

Yes but the way you are using the float * is innacurate since it's an uninitiized local variable and will be probably replaced by the memory manager which would explain the change of value...
