Camera Pos Dir
Hey!

I can't figure out camera handling after going through the tutorials. I want my camera during fighting to be set next to the player looking at a certain spot next to the monster he is battling.

I've experimented with something like this:
Code:
Vec pos = (50,30,50);
Vec dir = (0,0,0);

Cam.setPosDir(pos, dir);

I thought it was gonna set the camera in position x=50, y=30, z=50 and looking at point (0,0,0) on the map.

Apparently it doesn't and I'm having problems setting camera height (y coordinate), it doesn't seem to work.

Could anyone also explain "Vec up" of the Cam.setPosDir() function? I have no idea what it's responsible for as the only thing I figured out is it tilts the camera to the right...

Thanks,
Kiekos

RE: Camera Pos Dir
Dir is not position that camere looking at, but direction of camera rotations.

You can use something like this:
Vec pos = (50,30,50);
Vec target = (0,0,0);

Vec dir = pos-target; // or target-pos pfft can't remeber, too lazy to check
dir.normalize();
Cam.setPosDir(pos, dir);

Also there is Cam.setFromAt() function, that should do that what you want.

RE: Camera Pos Dir
Thanks for the quick feedback! It seems like Cam.setFromAt() should do the trick but it doesn't work because why would it work at the very first attempt? It never does... -.-

Code:
Vec pos    = (0,30,0 );
Vec target = (20,0,20);

Cam.setFromAt(pos, target);
Cam.updateVelocities().set();

So... As far as I know... It should set the camera to position (0,0) at height = 30 and make it look at point (20,20) at height = 0, right?

Well, the only thing that works is the position of the camera (0,0). Its height always equals zero (I cannot modify it, idk why) and it's not looking at the point I want it to.

Damn it...

RE: Camera Pos Dir
Vec pos(0, 30, 0);
or Vec pos=Vec(0, 30, 0);
You're initializing it wrong wink
