is the same code?

C++ coding using Panda3D
#1

Hi!
i try to translate a python code into a c++ code but I have done something wrong. The python code is this:

md = base.win.getPointer(0) 
x = md.getX() 
y = md.getY()
rotVel = 0.2
if base.win.movePointer(0, base.win.getXSize()/2, base.win.getYSize()/2):
    base.cam.setH(base.cam.getH() -  (x - base.win.getXSize()/2)*rotVel)
    base.cam.setP(base.cam.getP() - (y - base.win.getYSize()/2)*rotVel)

i have written this:

NodePath mouse = framework.get_window(0)->get_mouse();
int x = mouse.get_x();
int y = mouse.get_y();
GraphicsWindow* gw = framework.get_window(0)->get_graphics_window();
NodePath cam_group = framework.get_window(0)->get_camera_group();
if (gw->move_pointer(0, gw->get_properties().get_x_size()/2, gw->get_properties().get_y_size()/2)) {
    cam_group.set_h(cam_group.get_h() - (x - gw->get_properties().get_x_size()/2 * VEL_ROT));
    cam_group.set_p(cam_group.get_p() - (y - gw->get_properties().get_y_size()/2 * VEL_ROT));
}

These are not the same code: with the c++ code my environment jumps to the right and left at random (maybe is the camera that rotates?)

Where is the error?

thansk!

oki i find a solution:

GraphicsWindow* gw = framework.get_window(0)->get_graphics_window();
NodePath cam_group = framework.get_window(0)->get_camera_group();
int x = gw->get_pointer(0).get_x() - gw->get_properties().get_x_size() / 2;
int y = gw->get_pointer(0).get_y() - gw->get_properties().get_y_size() / 2;
if (gw->move_pointer(0, gw->get_properties().get_x_size()/2, gw->get_properties().get_y_size()/2)) {
    cam_group.set_h(cam_group.get_h() - (x * VEL_ROT));
    cam_group.set_p(cam_group.get_p() - (y* VEL_ROT));
}

Is a better solution exist?
