Hello all,
I'm trying to make my camera shake when the player is in the game's elevator... I've tried the Follow Spline animator, and it worked, BUT it never stopped. It wouldn't even stop when I removed the animator!

So any suggestions or ideas would be greatly appreciated...
Thanks very much~ John DiSanti

Hm, are you sure it never stops? Anyway you could try to use another camera while player uses elevator. And then switch back to the main cam.

Nice idea, I'll give that a go!

No problem, John. BTW - what is your project? Will it be released soon? Maybe some screenshots?..

I've wrote shake animator some time ago. Don't really know if it will help, but.. here's the code:

Code: Select all

class IShakeItAnimator : public ISceneNodeAnimator
{
    public:
        IShakeItAnimator(u32 ShakeTime, u16 Amp);
        virtual ~IShakeItAnimator() {};
        virtual void animateNode(ISceneNode *node, u32 timeMs);
    private:
        vector3df startPosition;
        u32 mStartTime;
        u32 mTimeToShake;
        u16 Amplitude;
        s8 Direction;
};

IShakeItAnimator::IShakeItAnimator(u32 ShakeTime, u16 Amp)
{
    mStartTime = 0;
    mTimeToShake = ShakeTime;
    Amplitude = Amp;
    Direction = 1;
}

void IShakeItAnimator::animateNode(ISceneNode *node, u32 timeMs)
{
    if (!mStartTime)
    {
        mStartTime = timeMs;
        startPosition = node->getPosition();
    }
    u32 passedTime = timeMs - mStartTime;
    if (passedTime > mTimeToShake)
    {
        node->setPosition(startPosition);
        return;
    }

    float progress = float(passedTime) / float(mTimeToShake);
    node->setPosition(vector3df(node->getPosition().X + ((1-progress)*Amplitude)*Direction, node->getPosition().Y, node->getPosition().X));
    Direction *= -1;
}

Of course it's very basic (and it shakes in X direction only:). It behaves like "single dinosaur's step;)" - first maximum impact, then amplitude goes to zero in given time.

Awesome work melon2005! I'll put that to good use!
Was it just me or were the Irrlicht forums really unbarably slow for a few days?

Puh, I've been working pretty hard on it... you can take a look on my new website:

I just finished the first level too.

your web address is not working

for shake animator: I use it for "world" node - and I'm not sure if it will work for anything else. But I'm sure it's easy to adapt.

Ooopps!!

bug in setPosition : use Z for Z, not X ?
