Original Post
I've posted earlier a thread about the same thing, but it still doesn't work.. The camera moves wrong, and I use this code to move forward/backward: and here is demo of how it moves wrong: http://members.lycos.nl/gideon715/map_test.html (click on the link on that page, with lycos you can't post the link to the file in one time :S)
[source lang="cpp]
void Bcamera::RotLeft(Bfloat angle) {
rotation.angle -= angle;
if (rotation.angle < 0) rotation.angle += 360.0f;
}
void Bcamera::RotRight(Bfloat angle) {
rotation.angle += angle;
if (rotation.angle > 359.0f) rotation.angle -= 360.0f;
}
void Bcamera::MoveForward(Bfloat distance) {
position.x -= (float) sin(rotation.angle * PI / 180) * distance;
position.z -= (float) cos(rotation.angle * PI / 180) * distance;
}
void Bcamera::MoveBackward(Bfloat distance) {
position.x += (float) sin(rotation.angle * PI / 180) * distance;
position.z += (float) cos(rotation.angle * PI / 180) * distance;
}

// (current matrixmode: GL_MODELVIEW)
glRotatef(current_cam->rotation.angle, current_cam->rotation.x, current_cam->rotation.y, current_cam->rotation.z);
glTranslatef(-current_cam->position.x, -current_cam->position.y, -current_cam->position.z);
