Teman-teman gw dpt info nie dari forum tetangga ni source code biar bs bergerak

Code:: #include "ExampleApplication.h" #include using namespace std; class MoveDemoListener : public ExampleFrameListener { public: MoveDemoListener(RenderWindow* win, Camera* cam, SceneNode *sn, Entity *ent, deque &walk) : ExampleFrameListener(win, cam, false, false), mNode(sn), mEntity(ent), mWalkList(walk) { // Set default values for variables mWalkSpeed = 35.0f; mDirection = Vector3::ZERO; } // MoveDemoListener /* This function is called to start the object moving to the next position in mWalkList. */ bool nextLocation() { if (mWalkList.empty()) return false; mDestination = mWalkList.front(); // this gets the front of the deque mWalkList.pop_front(); // this removes the front of the deque mDirection = mDestination - mNode->getPosition(); mDistance = mDirection.normalise(); Vector3 src = mNode->getOrientation() * Vector3::UNIT_X; if ((1.0f + src.dotProduct(mDirection)) < 0.0001f) { mNode->yaw(Degree(180)); } else { Ogre::Quaternion quat = src.getRotationTo(mDirection); mNode->rotate(quat); } // else return true; } // nextLocation() bool frameStarted(const FrameEvent &evt) { if (mDirection == Vector3::ZERO) { if (nextLocation()) { // Set walking animation mAnimationState = mEntity->getAnimationState("Walk"); mAnimationState->setLoop(true); mAnimationState->setEnabled(true); } } else { Real move = mWalkSpeed * evt.timeSinceLastFrame; mDistance -= move; if (mDistance <= 0.0f) { mNode->setPosition(mDestination); mDirection = Vector3::ZERO; // Set animation based on if the robot has another point to walk to. if (! nextLocation()) { // Set Idle animation mAnimationState = mEntity->getAnimationState("Idle"); mAnimationState->setLoop(true); mAnimationState->setEnabled(true); } else { // Rotation Code will go here later } } else { mNode->translate(mDirection * move); } // else } // if mAnimationState->addTime(evt.timeSinceLastFrame); return ExampleFrameListener::frameStarted(evt); } protected: Real mDistance; // The distance the object has left to travel Vector3 mDirection; // The direction the object is moving Vector3 mDestination; // The destination the object is moving towards AnimationState *mAnimationState; // The current animation state of the object Entity *mEntity; // The Entity we are animating SceneNode *mNode; // The SceneNode that the Entity is attached to std::deque mWalkList; // The list of points we are walking to Real mWalkSpeed; // The speed at which the object is moving }; class MoveDemoApplication : public ExampleApplication { protected: public: MoveDemoApplication() { } ~MoveDemoApplication() { } protected: Entity *mEntity; // The entity of the object we are animating SceneNode *mNode; // The SceneNode of the object we are moving std::deque mWalkList; // A deque containing the waypoints void createScene(void) { mSceneMgr->setSkyDome(true, "Examples/CloudySky", 5, 8); // Set the default lighting. mSceneMgr->setAmbientLight(ColourValue(1.0f, 1.0f, 1.0f)); // Create the entity mEntity = mSceneMgr->createEntity("Robot", "robot.mesh"); // Create the scene node mNode = mSceneMgr->getRootSceneNode()-> createChildSceneNode("RobotNode", Vector3(0.0f, 0.0f, 25.0f)); mNode->attachObject(mEntity); // Create the walking list mWalkList.push_back(Vector3(550.0f, 0.0f, 50.0f )); mWalkList.push_back(Vector3(-100.0f, 0.0f, -200.0f)); mWalkList.push_back(Vector3(0.0f, 0.0f, 25.0f)); // Create objects so we can see movement Entity *ent; SceneNode *node; ent = mSceneMgr->createEntity("Knot1", "knot.mesh"); node = mSceneMgr->getRootSceneNode()->createChildSceneNode("Knot1Node", Vector3(0.0f, -10.0f, 25.0f)); node->attachObject(ent); node->setScale(0.1f, 0.1f, 0.1f); ent = mSceneMgr->createEntity("Knot2", "knot.mesh"); node = mSceneMgr->getRootSceneNode()->createChildSceneNode("Knot2Node", Vector3(550.0f, -10.0f, 50.0f)); node->attachObject(ent); node->setScale(0.1f, 0.1f, 0.1f); ent = mSceneMgr->createEntity("Knot3", "knot.mesh"); node = mSceneMgr->getRootSceneNode()->createChildSceneNode("Knot3Node", Vector3(-100.0f, -10.0f,-200.0f)); node->attachObject(ent); node->setScale(0.1f, 0.1f, 0.1f); /*Plane plane(Vector3::UNIT_Y, 0); MeshManager::getSingleton().createPlane("ground", ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME, plane, 1500,1500,20,20,true,1,5,5,Vector3::UNIT_Z); Entity *ent2 = mSceneMgr->createEntity("GroundEntity", "ground"); mSceneMgr->getRootSceneNode()->createChildSceneNode()->attachObject(ent2); ent2->setMaterialName("Examples/GrassFloor"); ent2->setCastShadows(false);*/ // Set the camera to look at our handiwork mCamera->setPosition(90.0f, 280.0f, 535.0f); mCamera->pitch(Degree(-30.0f)); mCamera->yaw(Degree(-15.0f)); } void createFrameListener(void) { mFrameListener= new MoveDemoListener(mWindow, mCamera, mNode, mEntity, mWalkList); mFrameListener->showDebugOverlay(true); mRoot->addFrameListener(mFrameListener); } }; #if OGRE_PLATFORM == OGRE_PLATFORM_WIN32 #define WIN32_LEAN_AND_MEAN #include "windows.h" INT WINAPI WinMain(HINSTANCE hInst, HINSTANCE, LPSTR strCmdLine, INT) #else int main(int argc, char **argv) #endif { // Create application object MoveDemoApplication app; try { app.go(); } catch(Exception& e) { #if OGRE_PLATFORM == OGRE_PLATFORM_WIN32 MessageBox(NULL, e.getFullDescription().c_str(), "An exception has occurred!", MB_OK | MB_ICONERROR | MB_TASKMODAL); #else fprintf(stderr, "An exception has occurred: %s\n", e.getFullDescription().c_str()); #endif } return 0; }

Cara Penggunaan:
Source File yang dibuat menggunakan nama MoveDemo.cpp
Pada bagian
mSceneMgr->setSkyDome(true, "Examples/CloudySky", 5, Cool

;
adalah ..., 5, 8 ); bukan Cool

Saya
akan mencoba jelaskan sedikit tentang coding tersebut. Bagian-bagian
ini bisa dirubah, it's depends with the object. Hal lain yang perlu
diingat adalah animasi dari objek dalam source ini hanya dipanggil/dijalankan.
Untuk membuat animasi pada objek gunakan aplikasi 3d modeling seperti
blender3d, 3ds max, dll. Klo ada salah mohon dimaafkan, namanya juga
belajar... Wink

Berikut adalah sedikit penjelasannya:

Spoiler:

Buat yang mau mengetahui dan belajar langsung tentang logika program ini, bisa melihat link ini
atau mau belajar tentang tutorial ogre lain lihat link ini

Selamat Mencoba & Semoga Berguna
