Hello guys plzz help me out in correcting the code

Code: Select all

//PLZZ LET THE OBJECT BE SYDNEY.MD2 OR ANY BUILT IN OBJECT THAT COMES WITH IRRLICHT GAME ENGINE I DONT HAVE ANY DOWNLOADED OBJECT

//PLZ HELP THE NEW BIES IT WONT BE A TOUGH JOB FOR YOU GUYS I WOULD BE VERY THANKS TO U

//USE OF MASTEVENT RECEIVER CLASS OR YOUR OWN ANY CLASS IS APPRECIATED

//SUGGESTION ARE APPRECIATED

// THANKS A LOT IN ADVANCE

// I AM VERY WEAK IN THIS RECEIVER CLASS PLZZZ HELP OUT

plzz explain me some thing about event reciver class  i dont understand even after reading 4th tuitorial

what are the following lines for

core::vector3df v = node->getPosition();
v.X += event.KeyInput.Key == KEY_KEY_W ? -2.0f : 2.0f;

plz explain me about that a bit and about this lines especially that 2.0f and v.x 


and following lines in main and tell me how to connect and initialize that node

if (anms)	
{
	   
	   
       anms->setAnimationSpeed(30);   
	   
	   anms->setRotation(core::vector3df(0,180.0f,0));   
	   
	   anms->setMaterialTexture(0, driver->getTexture("../../media/sydney.bmp"));
}


     smgr->addCameraSceneNodeFPS(0, 1);
	 
	 device->getCursorControl()->setVisible(false); 

And again in advance thanks a lot for any help granted

[prajay.shetty]

plzz tell me something about evenreciver and those nodes

[spooky_paul]

when you are creating a piece of software you realize that you spend more on debugging the code than actually writing it. the best thing that you can do now is to learn proper debugging. posting an industrial-sized code snippet and asking other people to do your work wont get you anywhere.

[Dances]

an industrial-sized code snippet.

I actually don't think that is very large. I have many c++ files that are 500 lines or more.. they get somewhat hard to navigate, though.

That being said I agree his snippet is long enough no one will bother to read it.

I do like the teminology, though XD

[spooky_paul]

thanks, but all i was trying to do is to point him in the right direction

[bitplane]

v.X += event.KeyInput.Key == KEY_KEY_W ? -2.0f : 2.0f;

plz explain me about that a bit and about this lines especially that 2.0f and v.x

it's called a "ternary if" or "conditional operator", it allows an if statement as an expression. use it like this:
condition ? result_if_condition_is_true : result_if_condition_is_false

for example, in english:
increase x by ( -1 if c is true, or +1 if c is false )

in c:

Code: Select all

x += (c == true) ? -1 : 1;

[GameDude]

Dosen't negative move it left and positive move it right?
