Questions on the starting point of createFlyCircleAnimator()

Hello, I am new to Irrlicht and 3D modelling and I am a university student from Hong Kong.

I have a question on Irrlicht is that "can we set the starting point and the ending point when using the fucntion createFlyCircleAnimator()? ". In fact, I want to attach the camera to this flying node. But the starting point of the camera is not suitable for me.

Can anyone help me a bit? Thanks.

Here are some of my code:

cam = smgr->addCameraSceneNode(0, core::vector3df(0,80,-100), core::vector3df(0,0,0));

anim =smgr->createFlyCircleAnimator(core::vector3df(0,80,0), 100.0f, 0.0001f,core::vector3df(0.f, 1.f, 0.f));

cam->addAnimator(anim);

There's no method to do that at the moment, but Irrlicht is very easy to modify. Features get added when somebody wants to add them...

Thanks for your reply.

May be I just set the camera point by point to solve this problem.

or you can hack it a little

if you check the irrlicht's createFlyCircleAnimator method, you'll see, that the original method needs start time.
if you set it time - something or + something, it will start at the other place
i made 3 stars at the top of my characters head with this method xD

oops...you mean you change the .h file yourself ?

"attach the camera to this flying node" you mean like in tech demo source code?

In SVN 2105 on the trunk, createFlyCircleAnimator() now has a startPosition parameter that allows you to specify a start position in multiples of a circle, from 0.0f to 1.0f.

Comment, suggestions, Alyson Hannigan's phone number all welcome.

You are right

I try to modify them and put into in my application.

It sounds good. With these improvements, Irrlicht can be more efficient.

I don't know about Irrlicht, but if I ever get Alyson Hannigan's phone number, you can forget about seeing any patches from me for the next decade or so.
