i'm using ogre 1.8 on the iphone xcode4

i'm trying to animate the camera from point A to point B.
for start all i want is to move the camera say from 0,0,100 to 0,0,150 within x seconds.

i looked at the forum and the sample and did the following:

Code: Select all

void OgreFramework::InitCameraAnimations()
{

    mCamNode = m_pSceneMgr->getRootSceneNode()->createChildSceneNode("camera node");
    mCamNode->attachObject(m_pCamera);

    Ogre::Animation* mCamAnim = m_pSceneMgr->createAnimation( "Camera Animation", 10 );
    mCamAnim ->setInterpolationMode( Ogre::Animation::IM_SPLINE );
   // mCamAnim->setRotationInterpolationMode(Animation::RIM_SPHERICAL);

    Ogre::NodeAnimationTrack* mCamTrack = mCamAnim->createNodeTrack( 0, mCamNode );

   // mCamTrack->setUseShortestRotationPath( true );

    Ogre::TransformKeyFrame* mCamKey;
   
    mCamKey= mCamTrack->createNodeKeyFrame( 0 );
    mCamKey->setTranslate( Ogre::Vector3(0, 0, 100) );
  
   mCamKey= mCamTrack->createNodeKeyFrame( 10 );
   mCamKey->setTranslate( Ogre::Vector3(0, 0, 150) );

    //mCamKey->setRotation( Ogre::Quaternion(0.1,0.1,0.1,0.1) );

    mCamAnimState = m_pSceneMgr->createAnimationState( "Camera Animation" );
}

and then when i want to start the animation im doing :

Code: Select all

mCamAnimState ->setEnabled( true );

the effect im getting is that the animation is happening but immediately!
not during the 10 seconds i entered.

what could the problem be?

thanks alot !

mCamKey= mCamTrack->createNodeKeyFrame( 10 );

what if i want the animation to be x seconds no matter what the FPS is ?
can i do this using the method above?

does the function

Code: Select all

createAnimation( "Camera Animation", 10 );

also takes frames and not seconds?


unrelated Q:
regarding masterfalfon's post, is it better to use displayLink rather than NSTimer on iphones?

thanks

dowi wrote:hi again

i tried a lot of different settings for the FPS and played with

setEnabled
setLoop
setTimePosition
addTime

divided timeSinceLastFrame by 1000 to make it [sec]

and non of the above worked for me : (

if still get the animation i want but it happens immediately
from keyFrame(0) to keyFrame(last)

do you guys can think of a way to solve this or work around it?
thanks in advance
