Change Color on Mouse Click. How!?

Hi all,

I want to change the color of a model when the user right clicks on mouse.

The following is my code:

[code] #include “Scripts/Utilities/Sample.as”

Node@ mushroomNode;
StaticModel@ mushroomObject;
Material@ My_Mat;
ValueAnimation@ My_Color;

bool My_Click = false;
bool My_Click2 = false;
int Clk = 1;

void Start()
{
SampleStart();
CreateScene();
SetupViewport();
SubscribeToEvents();
}

void CreateScene()
{
scene_ = Scene();
scene_.CreateComponent(“Octree”);

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;
light.brightness = 2.0f;

    My_Mat = cache.GetResource("Material", "Materials/wire_255013019.xml");
    My_Color = ValueAnimation();

            mushroomNode = scene_.CreateChild("Mushroom");

                    mushroomNode.position = Vector3(0.0f, 0.0f, 300.0f);

            mushroomNode.rotation = Quaternion(0.0f, 0.0f, 0.0f);
            mushroomNode.SetScale(0.5f);
            mushroomObject = mushroomNode.CreateComponent("StaticModel");

            mushroomObject.model = cache.GetResource("Model", "3D_Models/Shoe_3.mdl");
            mushroomObject.ApplyMaterialList();

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


cameraNode = scene_.CreateChild("Camera");
cameraNode.CreateComponent("Camera");
cameraNode.position = Vector3(0.0f, 20.0f, 0.0f);

}

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

void MoveCamera(float timeStep)
{
if (ui.focusElement !is null)
return;

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.Rotate(Quaternion(MOUSE_SENSITIVITY * mouseMove.x, MOUSE_SENSITIVITY * mouseMove.y, 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);

if (input.keyDown['Z'])
    mushroomNode.position = Vector3(0.0f, 0.0f, 400.0f);
if (input.keyDown['X'])
    mushroomNode.position = Vector3(0.0f, 0.0f, 500.0f);


    if (input.mouseButtonPress[MOUSEB_LEFT])
    {
            My_Click = !My_Click;
            if (My_Click)
                    Clk = 0;
            else
                    Clk = 1;
    }


    if (input.mouseButtonPress[MOUSEB_RIGHT])
    {
            My_Click2 = !My_Click2;
            if (My_Click2)
                    My_Color.SetKeyFrame(0.0f, Variant(Color(0.0f, 0.0f, 0.1f, 1.0f)));
            else
                    My_Color.SetKeyFrame(0.0f, Variant(Color(1.0f, 0.0f, 0.1f, 1.0f)));

            mushroomObject.model = cache.GetResource("Model", "3D_Models/Shoe_3.mdl");
            My_Mat.SetShaderParameterAnimation("MatDiffColor", My_Color);
            mushroomObject.ApplyMaterialList();
    }

}

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

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

class Rotator : ScriptObject

{
Vector3 rotationSpeed;
void Update(float timeStep)
{
node.Rotate(Quaternion(rotationSpeed.x * timeStep * Clk, rotationSpeed.y * timeStep * Clk, rotationSpeed.z *$
}
}

String patchInstructions = “”;[/code]

Everything works fine, but the color doesn’t change on right click.
What is the problem !!?

At first look you never apply your material to your StaticModel

[quote=“Dave82”]At first look you never apply your material to your StaticModel

I have imported this .obj model by AssetImporter. It creates a .txt file containing the list of 3 .xml material files.
So, I apply the materials with :

But I want to change only one of those .xml material files.

So, what should I do !!?

Have a look at ValueAnimation documentation and samples 30_LightAnimation/31_MaterialAnimation. Then ponder if it actually suits your needs.
If not, simply get your material and modify its color:

Thanks @Mike for your reply.
I’ve used sample codes from examples 30 and 31, but no help.

If I use this code:

Do I have to run

to be applied !? or not !?

Calling ApplyMaterialList() once in CreateScene() is enough, calling it after resets the materials, the exact opposite of what you want to achieve (apply new color value).

Thanks @Mike for your reply.
This solved the problem.
