Selection | GameDev.net

Today I worked on mouse picking. I can click the exclamation mark using query masks and I have enabled a bounding box around the quest marker when I click it so that the selection is visible. Also I have a camera look working with the right mouse button but that is temporary until I get some camera movement implemented.

Here is the selection code:

    def select_object(self, evt):        scene_manager = self.screenMgr.getSceneMgr()        mouse_pos = CEGUI.MouseCursor.getSingleton().getPosition()        mouse_x = mouse_pos.d_x        mouse_y = mouse_pos.d_y        trans_x = float(mouse_x/self.screenMgr.getViewPort().actualWidth)        trans_y = float(mouse_y/self.screenMgr.getViewPort().actualHeight)                mouse_ray = self.game_camera.getCameraToViewportRay(trans_x, trans_y)                if self.ray_scene_query:            self.ray_scene_query.setRay(mouse_ray)        else:            self.ray_scene_query = scene_manager.createRayQuery(mouse_ray)                    self.ray_scene_query.setSortByDistance(True)        self.ray_scene_query.setQueryMask(self.EXCLAIM_MASK)                result = self.ray_scene_query.execute()                if len(result) > 0:            for item in result:                if item.movable:                    print item.movable.getName()                    item.movable.getParentSceneNode().showBoundingBox(True)                    CEGUI.WindowManager.getSingleton().getWindow("desptxt").setText(item.movable.getName()+" selected")                            self.ray_scene_query.clearResults()
