Problems moving camera in program

[darthneo]

Hi everyone,
Okay i am trying to make the camera move when you press W but when it runs as a program it comes up with that microsoft error crap and says it needs to be closed here is a few parts of my code

Code: Select all

class MyEventReceiver : public IEventReceiver
{
      public:	virtual bool OnEvent(SEvent event)	
      {
              if (event.KeyInput.Key) 
               {
                    if(event.KeyInput.Key == KEY_KEY_W)
                    {
                      camera->setPosition(core::vector3df(300,1000,-2100));
                    }
               } 
      }
};

now here is my camera settings:

Code: Select all

	scene::ICameraSceneNode* camera = 
		smgr->addCameraSceneNodeFPS(0, 100.0f, 300.0f, -1, 0, 0, false);
	camera->setPosition(core::vector3df(300,1000,-2100));
 	scene::ISceneNodeAnimator* anim = smgr->createCollisionResponseAnimator(
		selector, camera, core::vector3df(30,50,30),
		core::vector3df(0,-1,0), 
		core::vector3df(0,0,0));
	camera->addAnimator(anim);
	anim->drop();

now here is the error i am getting from windows:

example.exe has encountered a problem and needs to close. we are sorry for the inconvenience.

i get that everytime i press W running my program

i have tried changing the code i have tried to repostition my camera and i still get the same thing if i leave it blank i dont get any error (but nothing heppens).

does any one see anything wrong with my code? or any other way i can get the camera to rotate?

--edit--
i forgot to say of course i am using irrlicht engine and Dev C++ compiler

First your camera is already a fps cam, so you can define the keymap to response on the "W" key (look at the docu for addCameraSceneNodeFPS for this)...

Second your camera is not global so the camera pointer in your event receiver is probably 0 (NULL) !!!
(I wonder that you don't get an "variable not defined" error while compiling the prog)

Another thing you might want to do is check that the event you are getting is actually a key input event. It might also be useful to check that the key is pressed down or released so you don't do the same thing twice when the key is pressed.

Okay i am trying to make the camera move when you press W

This may or may not be of use to you, but here's what I use to specify which keys move my camera in simple demos:

Code: Select all

	SKeyMap keyMapArray[4] = {
		{EKA_MOVE_FORWARD,	KEY_KEY_W},
		{EKA_MOVE_BACKWARD,  KEY_KEY_S},
		{EKA_STRAFE_LEFT,	 KEY_KEY_A},
		{EKA_STRAFE_RIGHT,	KEY_KEY_D},
	};
	smgr->addCameraSceneNodeFPS(0, 100.0f, 100.0f, -1, &keyMapArray[0], 4);
