I had written a full update but then my browser crashed and ate it.



I don't feel like spending another hour rewriting the whole thing so this is going to be quick.

First off, I made a mistake in part 6 that may cause in part 7. When our animation is defined in the constructor "mesh_Ascent" is not attatched to anything and wont be until we call the "addmesh" function in clbkSetClassCaps. This will cause what we are about...

So now our ShuttlePB looks like a Lunar Lander...

I know I said that we'd talk about animations next, but as I was writing this I realised that even doing something comparatively simple like making the EVA Hatch open and close requires us to understand a bit about the way that orbiter controls individual vessels.

PART 3: Call Back Functions

Call Back functions are used by the Orbiter core to update a vessel's state within the simulation and notify it...

Well it's been a while since I've tried something new in the world of programming! I am always learning new things, but I rarely decide to try and make the jump from programming in a very basic graphics engine such as GDI+ (which I've been using so far) into programming in a professional display engine like DirectX.

I found a good tutorial recently though (after a lot of looking), and I managed to create my first 3D program which displays a rotating pyramid lit by a point source of...

Authors Note:
I know little to nothing about c++ outside the bounds of Orbiter's API.

I'm writing this tutorial in the hopes that it will help other hobbiests, tinkerers, and budding addon developers avoid the stupid mistakes and general frustration I've subjected myself to.

Further More if you want the meshes and complete code used in this tutorial dowload my addon.

With that out of the way, Let's Begin...

So I got the lego shuttle Expidition for Christmas and it took me 2 days to finish it,so here is how it went(Photos will come later!!!)......
Day 1:There it was I was going crazy to build the lego shuttle,every lego in the house was had less pieces then it.I then ran over to get a scissor I then walked back(just to be safe.)when I finally got everything I started building.After a few minutes I stoped to hear my dog Missi run into the room."Go away Missi!" I yelled as I hid my legos...
