Simultaneous automatic and manual rotation of object

Hi all,

I want to set up a scene, where a model is rotating automatically. Besides, the user will be able to rotate the model manually by mouse movement.
In other words, the total rotation will be the “automatic rotation + mouse rotation”.

The following is the code I’ve written:

[code]#include “Scripts/Utilities/”

Node@ mushroomNode;

void Start()

void CreateScene()
scene_ = Scene();


Node@ lightNode = scene_.CreateChild("DirectionalLight");
lightNode.direction = Vector3(0.6f, -1.0f, 0.8f); // The direction vector does not need to be normalized
Light@ light = lightNode.CreateComponent("Light");
light.lightType = LIGHT_DIRECTIONAL;

    mushroomNode = scene_.CreateChild("Mushroom");
    mushroomNode.position = Vector3(0.0f, 0.0f, 300.0f);
    mushroomNode.rotation = Quaternion(0.0f, 0.0f, 0.0f);
    StaticModel@ mushroomObject = mushroomNode.CreateComponent("StaticModel");
    mushroomObject.model = cache.GetResource("Model", "3D_Models/Shoe_2.mdl");

    ScriptInstance@ instance = mushroomNode.CreateComponent("ScriptInstance");
    instance.CreateObject(scriptFile, "Rotator");
    Rotator@ rotator = cast<Rotator>(instance.scriptObject);
    rotator.rotationSpeed = Vector3(10.0f, 20.0f, 30.0f);

cameraNode = scene_.CreateChild("Camera");

cameraNode.position = Vector3(0.0f, 30.0f, 0.0f);


void SetupViewport()
Viewport@ viewport = Viewport(scene_, cameraNode.GetComponent(“Camera”));
renderer.viewports[0] = viewport;

void MoveCamera(float timeStep)
// this function moves the object, not the camera. Only its name is camera !!
if (ui.focusElement !is null)

const float MOVE_SPEED = 10.0f;
const float MOUSE_SENSITIVITY = 0.05f;

IntVector2 mouseMove = input.mouseMove;
yaw += MOUSE_SENSITIVITY * mouseMove.x;
pitch += MOUSE_SENSITIVITY * mouseMove.y;
pitch = Clamp(pitch, -90.0f, 90.0f);

 mushroomNode.rotation = Quaternion(pitch, yaw, 0.0f);

if (input.keyDown['W'])
    cameraNode.Translate(Vector3(0.0f, -5.0f, 0.0f) * MOVE_SPEED * timeStep);
if (input.keyDown['S'])
    cameraNode.Translate(Vector3(0.0f, 5.0f, 0.0f) * MOVE_SPEED * timeStep);
if (input.keyDown['A'])
    cameraNode.Translate(Vector3(5.0f, 0.0f, 0.0f) * MOVE_SPEED * timeStep);
if (input.keyDown['D'])
    cameraNode.Translate(Vector3(-5.0f, 0.0f, 0.0f) * MOVE_SPEED * timeStep);
if (input.keyDown['Q'])
    cameraNode.Translate(Vector3(0.0f, 0.0f, -5.0f) * MOVE_SPEED * timeStep);
if (input.keyDown['E'])
    cameraNode.Translate(Vector3(0.0f, 0.0f, 5.0f) * MOVE_SPEED * timeStep);


void SubscribeToEvents()
SubscribeToEvent(“Update”, “HandleUpdate”);

void HandleUpdate(StringHash eventType, VariantMap& eventData)
float timeStep = eventData[“TimeStep”].GetFloat();

class Rotator : ScriptObject
Vector3 rotationSpeed;

    void Update(float timeStep)
            node.Rotate(Quaternion(rotationSpeed.x * timeStep, rotationSpeed.y * timeStep, rotationSpeed.z$


String patchInstructions = “”;[/code]

But unfortunately, it doesn’t rotate the object automatically.
But if I comment out the following line:

which is responsible for rotating the object by mouse, it works.
It means that either automatic or manual rotation works, but not both at the same time.

How can I make them both work at the same time !!?

“Rotator” rotate object but after that you rewrite rotation by “mushroomNode.rotation”. You need use “node.Rotate()” instead “node.rotation”.

Thanks @1vanK for your reply.
This solved my problem :wink:
