NxOgre Tutorials

Hi there,
i started to writing toutorials for NxOgre.
I'll try to write one a day

Here's come th first tutorial:
Simple Sample
That's what you can find in it:
* 1 What do you need
* 2 Compiling NxOgre
* 3 Creating new project
* 4 Initializing nxogre
* 5 Simple box on floor
* 6 Source code

It's quite nice; but you should put the classic one-line to create a body code in there, best before you explain NodeRenderable and Actor params. Otherwise it will confuse people when they see it done otherwise.

Classic? you mean that:
Actor* mActor = mScene->createActor("Spot", new Cube(1.0f), Vector3(0, 2, 0), "mass: 10");


I'll change it, it's better and shorter

Hey thanks for your work on this!

What do you think about it now betajen?

I hate theory but the first tutorial is almost only theory. Next will be more practical

I dunno. It's more there, and you are teaching some new things. But there are some things need to be fixed.

- You are copying some things directly from the guide. Which I don't mind, but you have to rewrite what you copied, or better still use the guide as inspiration and write your own.
- Some parts are quite complicated and hard to read; i.e. describing what the params.
- Some of your C++ code could be simplified and cleaned up.
- You need a proof-reader/editor that a natural English speaker to clean it up. i.e. bodys => bodies, u = you.

Take it as constructive criticism. I know how hard it is to write documentation, and even I have help with it.

that's right i just copyed a part about physx params
i have no idea how to write it myself. You made it to complicated, in physx some things are easyer, some not.
- Some of your C++ code could be simplified and cleaned up.
give me a line of my code that can be writen more simply.
I know that source code in wiki looks very poor(all code is black) but originaly it's look much better

sorry but im not from england, but anyway you using even more waird words like dunno

Wiki is a open source, maybe someone reading this will write it better.

There's a difference between a professional writing and something you'd write on a forum, IM, or e-mail.

The wiki should be something that is professional, easy-to-read, and grammatically correct.

I tried to fix it. It's the best I can do without rewriting the whole thing. I didn't mess with the last, larger bits of code.

I know that but my writing style is a bit chaotic

Anyway, thanks for your hard work reading it

I'll keep writing new toutorials

There is an error at the end of the SimpleSampleApplication::CreateScene


mNxScene->createActor(new Terrain(


i think its a good tutorial, thanks !

i used OgreNewt as a wrapper around the Newton physics library in a game i made last year. im going to re-do the game now with NxOgre because Newton has a major bug that i cannot work around. and this tutorial was a perfect starting point.

cheers !

thanks a lot for your tutorials, i's really helpfull

This is really useful, thanks.

One little thing which isn't great.
ExampleApplication.h - It's possibly the most annoying file i've ever come across and it took me a while to find tutorials which didn't use it, thanks to Nullsquared's softshadow demo.

Hi everybody!
I tried this tutorial and I compiled it with no errors. Then I ran it and i only had a black screen. So I thought I might have done a little mistake somewhere. So I copied the complete provided source code into my program and I had the same result (no compile errors but only a black screen after running). Does anybody know what I could have done wrong.
Any help would be appreciated.
Thanks in advance!

Oh, btw, I had to include the NxOgreStatic_d.lib instead of the NxOgre_d.lib, because after compiling NxOgre the NxOgre_d.lib did not exist. Only the NxOgreStatic_d.lib existed. Could that be the reason why it didn't run? If yes, what do I do?

The NxOgre_d.lib will be created if you choose "Debug" from the solution target instead of "Debug_static". ( drop-down list up high in the middle )

i ended up copying the files from sdk into NXOGRE_DIR/lib and /include respectively and renamed NxOgre_debug.lib to make things easier for future projects, and that worked, but i'm still getting these 2 errors:

c:\users\chris\documents\visual studio 2008\projects\nxogre test\nxogre test 1\nxogre test 1\definition.h(106) : error C2664: 'NxOgre::World::World(NxOgre::WorldPrototype *)' : cannot convert parameter 1 from 'const char [30]' to 'NxOgre::WorldPrototype *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
c:\users\chris\documents\visual studio 2008\projects\nxogre test\nxogre test 1\nxogre test 1\definition.h(113) : error C2661: 'NxOgre::World::createScene' : no overloaded function takes 3 arguments

I dont know what i can do to fix it, it happens when i follow the NxOgre Simple Sample tutorial on the wiki, copied it exactly and it still gives me that. not sure what to do really

i get the same problem, how you solve?

Because the tutorials you followed (this strange Simple Sample thingy) was written for an old and outdated NxOgre version. Have a look at the NxOgre portal and follow my tutorials there.

Hi:

I been following the first tutorial, when I compile the project he doesn't have any bug's but in runtime there is this error that is driving me crazy:


OGRE EXCEPTION(4:ItemIdentityException): An object of type 'Entity' with name '-Entity' already exists. SceneManager::createMovableObject at f:\codingextra\ogre\shoggoth_vc9\ogre\ogremain\src\ogrescenemanager.cpp (line 6136)

I manage to pinpoint the error to this line of code:
mCube2 = mRenderSystem->createBody(new NxOgre::Box(1, 1, 1), NxOgre::Vec3(0, 20, 0), "cube.1m.mesh");

Is in the second create cube line,(above) I suppose I have to give to the new shape a unique name but I don't know how do that.

Is there a way to do that????

I would appreciate any help.

Shinigami out.....
