Can CSceneNodeAnimatorFollowSpline be set to not looping?

I want to use CSceneNodeAnimatorFollowSpline for animating my camera. But I don't want the animation to loop. Is there any way to know if the animation is finished so I can stop the animation?

Sorry, SceneNodeAnimatorFollowSpline misses a loop parameter so far. So for now you have to create your own animator. Just copy CSceneNodeAnimatorFollowSpline.cpp and .h rename the classes for a start.

Then derive your animator from ISceneNodeAnimatorFinishing instead of ISceneNodeAnimator.

And in animateNode you should probably change that line:

Code: Select all

const s32 idx = core::floor32( dt ) % pSize;

in something like that (untested):

Code: Select all

const s32 idx = core::floor32( dt );
if ( idx >= pSize )
{
    HasFinished = true;
    node->setPosition(Points[pSize-1]);
    return;
}

If you add this to the feature-tracker you increase the chance that we think of adding this to the engine.

thanks! I did as you said and derived a own Animator class. It works fine.
