Irrlicht Engine

Hi,
I plan to make a 2D game using the Irrlicht engine.

So for in the prototype i have used an orthographic projection (left) with the camera fixed looking down the Y-axis.

Now, the issue is the coordinate system is completely different from the coordinate system in 2D libs where the origin is ...

Yes, dummy node technique sounds nice. I will experiment with it. Also, the i had a feeling that the positions were being reset and stuff, but your info has claried it for me thanx.

Hi,
I have been trying to rotate a quad around it center but SetRotate() rotates it relative to the upper left vertex
So i tried this way..

//translate the quad by a set offset to locate your origin for rotation
core::vector3df tpos = quad->getPosition();
tpos.X += 5;
tpos.Y += 5;
quad ...

Ohh i c, yes the nodes could be loaded twice. So i will have to limit the call to once only.
Thanx very much for giving me this info.

Hi,
I am loading a scene in an .irr file by calling LoadScene().

If i call it twice before the game loop begins, does the scenemanager load the scene twice in memory ??

I checked the output window in vs2010, it shows the App, loading the files and textures only once. But i wanted to make sure ...

I will experiment with your code as well. But as u said the sleep function can waste CPU cylces.
Could there be a way without calling sleep .

Thanx for all your answers again.

I realize that using frame rate independent movement would be good.
But i am working on a networked game. So i want to make sure that all clients are running at same frame rates. Thats why i want to lock it.

I will try the yield function technique above. Any other suggestions would be welcome ...

Hi,
How can i lock the irrlicht frame rate to a chosen value ?

Thank u very much.

That getElementFromID() is called from the root element. Which u have brought to my attention.

Thank you again.

Hi,
I have created a user interface using the GUI editor and outputted an xml file with the ui settings.


After i load it into the GUIEnvironment using LoadGUI(), how can i access the individual GUI elements ?


Would i have to create the element that i want to access manually (using the ...

Ok. i tried what u said earlier . It creates a new instance. Thanks for your help .

Thanks for the reply.

Ok, so you mean, calling getSceneManager() first time, returns the default sceneManager.

Then calling it again return a new instance of the sceneMgr ?

Hi,
does the call to :

'

get a ptr to a new sceneManager, or is the there only a single instance of the scenemanager.

I have seen the irrlicht 2d tut, but can it provide features which a conentional 2d engine like haaf's game engine would provide,
Mainly,
2d lighting effects,
2d camera.

Thnx in advance.

Hi, besides the built in GUI system in Irrlicht, are there any alternative GUIs for Irrlicht. ?

Thanx in advance.
