Title: serialize related questions
Post by: John Tribe on March 01, 2013, 12:05:46 am

1. is serialize() save transformedCenterData and size information?
2. is there a way to force save this data
3. is ID change when deserialize and add to world? If not, what you suggest to make relation with another data .. like game Data?
4. is call compile and build,  clear some information? (e.g. position, rotation)

sorry for the stupidity

• Center and rotation pivot will be saved. Translations, rotations, scale etc. won't.
• No. You have to save this yourself if you need it.
• I don't get the question...
• compile() doesn't but build() recalculates the center and the rotation pivot. Translations and rotations will remain untouched but their actual outcome may change because of the recalculated center.

About 3 :

I have the hero and monster object the all of them have they own object3d. and if i save the object3d[] array of all of them(as one array) and hero objects and monster objects i save as gameObjects[] array, then when i loading i need to create mapping with the heros , monster objects and objects3d ,first i thought that id is unique, but isn't. Do you have any ideas? I can use name field for this, but i would like to leave this for display purpose. 

Thanks for help

Even if the id would have been stored in the file, you can't ensure that it will be unique after loading because you might have saved multiple objects with the same id.

How do you store your objects? Make sure that you aren't storing them in reduced mode.
