Irrlicht Engine

Use your debugger to see what's really happening, then if you are still stuck, provide all usefull information you got while using the debugger.
If you never used a debugger before, I strongly suggest you take some time to learn how to use it; it will make your life much more easier in the future ...

Don't limit the frame rate. Instead, calculate the new position of your vehicle depending of the time elapsed since the last frame.

What do you want to do exactly ? Select a node when you click on it probably (that seems the most logical to me) ?
Then, why don't you simply check when you click with the mouse ? Don't need to calculate this all the time in a loop.

where pos is on the command i will need to place the x and y co ...

Don't do that: Just use the remove (or removeAll) function from your node.

Use getRotation from ISceneNode.

The mouse coordinates cannot be converted simply to a 3D position (because there is one dimension more). Instead, the mouse position can give you a ray that start from the camera position and goes 'inside' your screen. With that ray, you'll have to check for the collisions with other object.

Take a ...

Make this rectangle the size of your texture:

@mmh771: Both are perfectly correct ! This doesn't change anything.

Don't use a FPS camera. A standard camera will do the trick.
Look at the API documentation for the camera and you will see that there is a SetTarget method which you can use to specify the target viewed by the camera.

And BTW, don't cross-post !!

Show the code where the errors are and post the exact error messages.

BTW: Is it a better way to make a class instead to call a function?
Depends. If you want to add a class just for adding a class, then no, it is useless. I think you first need some more experience in object oriented programming ...

Show the code of both situations where you are calling this function. And check the solution of hybrid too (did you miss it ?).

it loaded but i cann't see that

What do you mean ? How did you check that it was loaded ? And what is the problem ?

Post code also so we can see what you are doing wrong.

@andrei25ni: what is the problem with using WinMain instead of a main ?

Also, changing "return (0);" into "return 0;" won't change anything.

And finally, it is perfectly legal to use "createDevice (EDT_SOFTWARE, dimension2d<s32>(640,480), 32, false, false, false,0);" when creating your device ...

In your main, you are declaring a local variable of device:

IrrlichtDevice *device =
createDevice (EDT_SOFTWARE, dimension2d<s32>(640,480), 32, false, false, false, 0);

So, at this point your global variable device is still a NULL pointer. Thus, in your event receiver (outside the scope of main ...

He meant that you'll need two sprites: one that contains your character without the weapon, and one containing only the weapon. Then you need to blit them separately on the screen (of course, you use a colorkey in order to avoid blitting everything that cannot be blitted).
