Program Ogre animasi sederhana

Hallo sobat blogger,
Kali ini saya akan meng share mengenai program membuat animasi sederhana pada Ogre 3d. Program ini cuman animasi sederhana. Anda cukup mengganti objek .mesh nya saja yang sudah saya tandai dengan warna biru. Selamat mencoba.

#include "ExampleApplication.h"

//--awalan untuk animasi pindah tempat----
#include <deque>
using namespace std;
//-----------------------------------------

class MoveDemoListener : public ExampleFrameListener
{
public:
MoveDemoListener(RenderWindow* win, Camera* cam, SceneNode *sn, deque<Vector3> &walk)
: ExampleFrameListener(win, cam, false, false), mNode(sn), mWalkList(walk)
{

//---tempat pemberian nilai awal untuk variabel-variabel yg digunakan
mWalkSpeed = 8000.0f;
mDirection = Vector3::ZERO;
//-----------------------------------------------------------------------

}

//--Fungsi ini dipanggil untuk memulai perpindahan objek ke posisi selanjutnya dalam mWalkList.
bool nextLocation()
{
if (mWalkList.empty()) return true;

mDestination = mWalkList.front(); // ini untuk mendapatkan posisi depan deque
mWalkList.pop_front(); // ini untuk menghapus posisi depan deque

mDirection = mDestination - mNode->getPosition();
mDistance = mDirection.normalise();

Vector3 src = mNode->getOrientation() * Vector3::UNIT_Z;
if ((1.0f + src.dotProduct(mDirection)) < 0.0001f)
{
mNode->yaw(Degree(180));

}
else
{
Ogre::Quaternion quat = src.getRotationTo(mDirection);
mNode->rotate(quat);
mWalkSpeed = 10000.0f;

}
return true;
}


bool frameStarted(const FrameEvent &evt)


{mNode->yaw(Radian(evt.timeSinceLastFrame));
if (mDirection == Vector3::ZERO)
{
//--gerakan animasi awal atau masih ada titik lokasi yang belum dikunjungi
if (nextLocation())
{
mWalkSpeed = 1000.0f;
mCamera->setPosition(Vector3(-4000,1500,2500));
mCamera->lookAt(Vector3(300,1000,1000));
}
}
else

mNode->translate(mDirection * move);
}
