Hello all,

I have created a program that creates a scene using basic shapes
loaded as X files and then multiplied using `Clone object`.
I have programmed certain keys to clone,scale,rotate and
move each object manually rather than in a program run.
It`s sort of a 3D construction program. Problem is that I
do not know how to save and reload the created scene so that
when reloaded all the cloned objects can remember their
position, scale, rotation and texture data.
Each scene can be made up of hundreds of objects and I would
like to know if their is a way to save all together as a scene,
allowing for future reloading whilst remembering positions,sizes,
rotation and texture data as originally created.
Thanks in advance for any help you can give. ( Code supplied ).

Yes, it's absolutely possible!

You can look at this : http://forum.thegamecreators.com/?m=forum_view&t=173880&b=1

It's an old abandoned project, but if you look at the code.It's fairly simple written.Good example of save and load routines.

I think you can make the same approach.Make an array with all your objects, their properties as scale, position, texture used and so on.Save it to a file, then load it in similar way.

I gtg to work but when go back i'm gonna look at your code and try to do it work that way if you are unable to do it yourself.It's a good challenge for me, because i lack of determination to start a project for some reason.It's frustrating.I get rusty, but that's not the main reason i can't code...

It should be as simple as,

- open a file
- write the model's filename
- write the x, y, and z position as floats
- write the x, y, and z rotation as floats

When loading, just loop through reading the data and load and position each object. Store the data in a UDT array and when you come across duplicate models just clone the new one from the first one you loaded.

Thanks for the advice given here.
Sadly my experience with arrays is nil.
Luskos, I would like your help to develop the code
necessary for making my project work.
Any progress that you make I would be interested in seeing.
My email address is: [email protected]
As you have not left an email address for me to contact you
I would appreciate it if you could email me directly,
so that I can work in with you.
Thanks again to all for helping me.

Arrays - get to know arrays and love them...
They will be your best friend when programming games!

An example UDT array might be,



Hope that helps.

KISTech example explained it very well.Looking at your code you are gonna need UDT like this:


It covers every object type, but spheres.
