Thanks&regards

Could you be a lot more specific about what is not displaying? Anything? The robot? The animation?

Hi ,
Yes , I am trying to dislay robot animation only
1) I took the robot.mesh and robot.skeleton files form the ogresdk and i have saved in my application
2)I created the entity and sene node

Code: Select all

  animtedEntityl=OgreFramework::getSingletonPtr()->m_pSceneMgr->createEntity("robot","robot.mesh");
       animateSceneNode=OgreFramework::getSingletonPtr()->m_pSceneMgr->getRootSceneNode()->createChildSceneNode("robotnode",Ogre::Vector3(0.0f, 0.0f, 25.0f));
       
    animateSceneNode->attachObject(animtedEntityl);

created the walk list
Create the walking list

Code: Select all

 mWalkList.push_back(Ogre::Vector3(550.0f,  0.0f,  50.0f ));
        mWalkList.push_back(Ogre::Vector3(-100.0f,  0.0f, -200.0f));

I have the created the objects

Code: Select all

Ogre::Entity *ent;
        Ogre::SceneNode *node;
        
        ent = OgreFramework::getSingletonPtr()->m_pSceneMgr->createEntity("Knot1", "knot.mesh");
        node = OgreFramework::getSingletonPtr()->m_pSceneMgr->getRootSceneNode()->createChildSceneNode("Knot1Node",

        node->attachObject(ent);
        node->setScale(0.1f, 0.1f, 0.1f);

Thanks. And what is the issue? Do you see any errors in the log? Have you tried debugging it?

[Ananditha Roy]

Hi ,

Issue is robot not animating . Its is not showing any error also . Just displaying the robot image and three knot.mesh . Thats it.
Do i need to call the frameRenderingQueued method separately . If so what will be the parameter i need . Sorry for not providing the all info at once

[masterfalcon]

Yes, you'll need to override frameRenderingQueued and call addTime on each animation that you want to update.
