fps camera y axis is inverted

[PaulBird]

my fps camera y axis is inverted, does anyone else have this problem? anyways i tried to fix it by adding this:

Code: Select all

        scene::ISceneNodeAnimatorCameraFPS *camAnim;
        camera->addAnimator(camAnim);
        camAnim->setInvertMouse(true);
        camAnim->drop();
 

but now when i run it it just shows a black screen!
heres my whole .cpp file..

Code: Select all

#include <irrlicht.h>
#include "driverChoice.h"
 
using namespace irr;
 
#ifdef _MSC_VER
#pragma comment(lib, "Irrlicht.lib")
#endif

any help? thanks

hi

i guess this code under works but i think its not the recommend way und sometimes not safe.

Code: Select all

((ISceneNodeAnimatorCameraFPS*)*camera->getAnimators().begin())->setInvertMouse(true);

edit:

much better is to delete all animators from the camera
und create a new one like this

Code: Select all

        scene::ISceneNodeAnimatorCameraFPS* anim = (scene::ISceneNodeAnimatorCameraFPS*)smgr->createSceneNodeAnimator("cameraFPS");
        anim->setInvertMouse(true);
        camera->addAnimator(anim);
        anim->drop();

irr::scene::ISceneManager has no function named createSceneNodeAnimator() though :\

[zerochen]

maybe you use a old version from irrlicht
i use trunk

[PaulBird]

maybe you use a old version from irrlicht
i use trunk

well even if mine is a little old, i checked the most recently updated api and that function still isnt in the ISceneManager :\

[PaulBird]

or maybe the api docs arent updated?

[PaulBird]

could someone show me how to do this on 1.7.3 instead of 1.8? thanks!

You are passing an unitialized variable camAnim - that can't work. You can never do anything sane with unitialized pointers. To see errors it might also be easier if you wouldn't work in fullscreen while debugging, then your IDE can already give you hints where it crashs.

[blAaarg]

Also, I believe addCameraSceneNodeFPS() adds a camera that already has an FPS animator on it.

O.o i dont see the problem. i had already post two solutions:/
