Smooth FPS camera

[oconv]

yeah, much smoother

thanks alot

isn't

Code: Select all

  if (cursorpos.X < 0.5f || cursorpos.X > 0.5f ||
    cursorpos.Y < 0.5f || cursorpos.Y > 0.5f)

the same as

Code: Select all

  if (cursorpos.X != 0.5f || cursorpos.Y != 0.5f)

if so, and I'm not completly dumb, why not use the other option?

[Guest]

why dont u just test out ur option and let us know of any differnece

FYI: I´ve just used Warui´s hack on ver. 0.8 - and it still does magic.

it sure does, dunno why it hasn't been made official.

Yes, I saw the same thing. That would be a better way of checking cursorpos.

You can use this code to set the fov using degrees instead of radians:

Code: Select all

3.14159f / (180f / (180 - degrees))

Simply replace "degrees" with the desired number of degrees (1-180) that you want your fov to be.

Regarding the smooth mouse code, I would also love to see this or a similar code being implemented to the official game engine. It is a requirement for any serious 3D app using the mouse for camera movements.

[yes]

sounds like it is using radians instead of degrees. radians are fractions of pi.

1.4 rads is very close to 90 degrees.

In case anyone doesn't understand how to use it... use this funtion.
Thanks to wintran.

Code: Select all

// Myth
void setFOVdegrees(ISceneNode *cam, const float degrees)
{
 cam->setFOV(3.14159f  / ( 180.0f / (180 - degrees)));
 return;
}

It gives sqrt: DOMAIN EXPECTION ERROR at runtime.

Any idea why?
