如何在运行时更改camerascenendefps键绑定

一种可能性是从一个普通的相机节点开始，然后附加一个SceneNodeAnimatorCameraFPS

irr::scene::ICameraSceneNode* camera;
irr::scene::ISceneNodeAnimatorCameraFPS* ca;

camera = _smngr->addCameraSceneNode();
irr::core::array<irr::SKeyMap> keyMap;
keyMap[0].Action = EKA_MOVE_FORWARD;
keyMap[0].KeyCode = KEY_UP;
keyMap[1].Action = EKA_MOVE_FORWARD;
keyMap[1].KeyCode = KEY_KEY_W;
keyMap[2].Action = EKA_MOVE_BACKWARD;
keyMap[2].KeyCode = KEY_DOWN;
keyMap[3].Action = EKA_MOVE_BACKWARD;
keyMap[3].KeyCode = KEY_KEY_S;
keyMap[4].Action = EKA_STRAFE_LEFT;
keyMap[4].KeyCode = KEY_LEFT;
keyMap[5].Action = EKA_STRAFE_LEFT;
keyMap[5].KeyCode = KEY_KEY_A;
keyMap[6].Action = EKA_STRAFE_RIGHT;
keyMap[6].KeyCode = KEY_RIGHT;
keyMap[7].Action = EKA_STRAFE_RIGHT;
keyMap[7].KeyCode = KEY_KEY_D;

ca->setKeyMap(keyMap);
camera->addAnimator(ca);

如果你以后想改变键绑定，那么只需改变正确的Keycode并使用

ca->setKeyMap(keyMap);

。

编辑:你也可以访问由场景管理器附加的动画器

camera = _smngr->addCameraSceneNodeFPS();
irr::core::list<irr::scene::ISceneNodeAnimator*>::ConstIterator al = camera->getAnimators().begin();
irr::scene::ISceneNodeAnimatorCameraFPS *a = (irr::scene::ISceneNodeAnimatorCameraFPS*)*al;

irr::core::array<irr::SKeyMap> keyMap;
keyMap[0].Action = EKA_MOVE_FORWARD;
keyMap[0].KeyCode = KEY_UP;
keyMap[1].Action = EKA_MOVE_FORWARD;
keyMap[1].KeyCode = KEY_KEY_W;
keyMap[2].Action = EKA_MOVE_BACKWARD;
keyMap[2].KeyCode = KEY_DOWN;
keyMap[3].Action = EKA_MOVE_BACKWARD;
keyMap[3].KeyCode = KEY_KEY_S;
keyMap[4].Action = EKA_STRAFE_LEFT;
keyMap[4].KeyCode = KEY_LEFT;
keyMap[5].Action = EKA_STRAFE_LEFT;
keyMap[5].KeyCode = KEY_KEY_A;
keyMap[6].Action = EKA_STRAFE_RIGHT;
keyMap[6].KeyCode = KEY_RIGHT;
keyMap[7].Action = EKA_STRAFE_RIGHT;
keyMap[7].KeyCode = KEY_KEY_D;

a->setKeyMap(keyMap);
