Hello everybody!!!
I am new in this area of programming I have evolved much more ...

Well, I'm here with a doubt with the camera.
-I did it, but I said in part as:
camera.pan = player.pan;
then the camera turns to the player right?
more I only rodasse camera, and the player remains, there I said this:
camera.pan = 10, / / the 10 is just one example
only when I turn the camera with this statement:
camera.pan + = 2 * (mouse_force) * time_step;
the camera rotates, but is not on axis with the player.

- and also when I turn the camera near a wall, it passes through the wall, Fasso and I to cross it in the wall?

if someone can help me, I will be very grateful.

camera code:

function camera()
{
...
while(1)
{
...
camera.x = player.x - 350 * cos (player.pan);//APROXIMA A camera.y = player.y - 350 * sin (player.pan); //DESLOCAMENTO
camera.z = player.z + 450; //VISAO ABAIXO OU ACIMA DO HEROI
camera.pan = player.pan; //O HEROI GIRA JUNTO COM A CAMERA
camera.tilt = -35;
wait(1);
}
}

sorry for my bad English, is that I'm from Brazil

this is not good:
camera.x = player.x - 350 * cos (player.pan);//APROXIMA A camera.y = player.y - 350 * sin (player.pan); //DESLOCAMENTO

You have written the camera.y stuff like a comment:

camera.x = player.x - 350 * cos (player.pan);//APROXIMA A
camera.y = player.y - 350 * sin (player.pan); //DESLOCAMENTO

Now it should work.

no ....

You should not have understood me, my error is not with the operation, but the way he works,
and is verdadena time that I put here in the forum that error happened there more to write my code this way:

camera.x = player.x - 350 * cos (player.pan);
camera.y = player.y - 350 * sin (player.pan);
camera.z = player.z + 450;
camera.tilt = -35;

waiting for answers...
