FPS Camera Speed Not Scaled When Dynamically Changed

[kkrizka]

Hi there,

I am trying to change the move speed of a FPS camera depending on its proximity to another object. Basically as the camera gets closer, it starts to slow down.

Here is how I accomplished it:

Code: Select all

core::list<ISceneNodeAnimator*>::ConstIterator anims=camera[0]->getAnimators().begin();
ISceneNodeAnimatorCameraFPS *anim=(ISceneNodeAnimatorCameraFPS*)*anims;
anim->setMoveSpeed(newCameraSpeed/1000);

Here is the problem that I had:
When I create the FPS camera, the constructor scales the move speed by 1000. However when I change the speed, the scaling does not happen and I have to do it myself. This seems a bit counter-intuitive to me, because I expect the scale of the move speed to be the same no matter from where I set it.

So I'm wondering, is there a reason why changing the speed does not scale the move speed automatically?

I think this is a bug which was "copied" from the old camera to the new animator...

Alright, should I open a bug report concerning this?

Also I've found another bug. When you remove the event reciever while holding down the one of the arrow keys, it still continues to move even after you let go of the arrow key. The reason for this is that since the animator no longer receives any events, it has no idea that you let go off the button and the array that holds the key presses still have a "true" value. A solution for this is to override the setEventReceiverEnabled function, and if the arguments is "false", then call allKeysUp().

I guess you found this: http://irrlicht.sourceforge.net/phpBB2/ ... hp?t=27742

There, rogerborg gives a partial solution -- it really helps with keyboard input (arrow keys), but no help been found with mouse movement: indeed, when you move the mouse and at the same time you do setEventReceiverEnabled(false); then you will not be able to use the mouse because camera takes it to the center of the screen -- all the time, until you do setEventReceiverEnabled(true); and then leave the mouse in piece .

That is a pity, indeed
