2. Project Statement • GlobalFlyer allows a player to fly a Wright brothers-style airplane in 3D space using the OGRE graphic rendering engine and the FMOD sound system.

3. Iteration Plans • Fixup • 1: Get music and sound effects working again • 2: Get collision detection with buildings working • 3: Update Ogre library versions • Visual Environment • 1: Add hovering objects to the world • 2: Add proximity detection to hovering objects • 3: Modify texture of hovering objects based on proximity • User Interface • 1: Add mouse control of camera • 2: Add visually-appealing digital readouts of data the user might want • 3: Add the ability to toggle sound, gui, etc.

5. The Plan and Analysis

6. Plan for Iteration 3

7. Comparisons of Effort

10. Earned Value • EV= Budgeted cost of Work Performed over Budgeted at Completion • Shows our the gradual completion of tasks over time

11. Schedule Performance Index • SPI= Budgeted Cost of Work Performed over Budgeted Cost of Work Schedule • Shows that we are always on or ahead of schedule

12. Schedule Variance • SV= Budgeted Cost of Work Performed minus Budgeted Cost of Work Schedule • Show how far ahead of schedule (or right on target) we were

13. Cost Performance Index • CPI= Budgeted Cost of Work Performed over Actual Cost of Work Performed • Show us under budget and over budget but finally ending under (just barely)

14. Cost Variance • CV= Budgeted Cost of Work Performed minus Actual Cost of Work Performed • Show just how much over and under budget we were

15. OCL

16. OCL • Areas that lend themselves well to OCL specifications • The airplane cannot fly beneath the ground • The FMOD sound system shouldn't be re-initialized • The bubbles and buildings must be within the boundaries of the world • Checking the win-condition for a level, theoretically we would load a new level after hitting all targets

17. OCL • The airplane cannot fly beneath the ground • context OgreCharacter::update(elapsedTime, *input) : void • post: self.raySceneQuery->forAll( worldFragment.singleIntersection.y < self.mMainNode.getPosition().y )

18. OCL • The FMOD sound system shouldn't be re-initialized • context CFMod::InitSoundSystem() : bool • pre: self.initialized = false • post: self.initialized = true

19. OCL • The bubbles and buildings must be within the boundaries of the world • context SampleApplication::createScene() : void • post: self.buildings.getBoundingBox->forAll( getMinimum.x >= 0 and getMinimum.z >= 0 and getMaximum.x <= 10000 and getMaximum.z <= 10000 ) • post: self.bubbles.getBoundingBox->forAll( getMinimum.x >= 0 and getMinimum.z >= 0 and getMaximum.x <= 10000 and getMaximum.z <= 10000 )

20. OCL • Checking the win-condition for a level -- theoretically we would load a new level after hitting all targets • context OgreCharacter::targetsRemaining() : int • result = self.targetHit->count(false) • context OgreCharacter::checkWin() : bool • result = self.targetsRemaining = 0 • context SampleListener::frameStarted(frameEvent) : void • post: self.mChar.checkWin = false

21. Testing Code void Sound::Play() { debug ("Sound::Play 1"); if (m_pSound != NULL) { debug ("Sound::Play 2a"); m_soundChannel = FSOUND_PlaySound(FSOUND_FREE, m_pSound); } else { debug ("Sound::Play 2b."); } debug ("Sound::Play 3 (last)"); }

22. Testing Output Airplane::Airplane (only) Airplane::GetPosit (only) Airplane::GetRelVeloc (only) Airplane::GetVeloc (only) Airplane::checkWin (only) Airplane::inObstacle 1 Airplane::inObstacle 2 Airplane::inObstacle 3a Airplane::inObstacle 3b. Airplane::inObstacle 4a Airplane::inObstacle 4b. Airplane::inObstacle 5a Airplane::inObstacle 5b. Airplane::inObstacle 6 (last)

23. Exceptions to C1 Sound::InitSoundSytem 3a -- would need an invalid version of fmod Sound::InitSoundSytem 4a -- would need a bad version of fmod Sound::Load 3a -- fmod would have to screw up to hit this case Sound::Mute 2b. -- fmod would have to screw up to hit this case Sound::Pause 2b. -- fmod would have to screw up to hit this case Sound::SetLoop 2b. -- fmod would have to screw up to hit this case bool Sound::Load(char *strName) { debug ("Sound::Load 1"); bool retval = false; // set to 'true' if successfully loaded // if FMOD isn't loaded, or strName is invalid, we can't load a sample if (initialized && strName) { debug ("Sound::Load 2a"); m_pSound = FSOUND_Sample_Load(FSOUND_FREE, strName, 0, 0, 0); // make sure we got a valid sound pointer if (!m_pSound ) { debug ("Sound::Load 3a"); // bad news, bail out with an error message DisplayError(); ……..

35. New Featuresand Updates

36. Library Update Ogre has updated from 1.2.3 to 1.4.0 during the year. We thought it might be nice to start next year’s team with updated code. 

37. Where’s the Keyboard? using namespace OIS; void Airplane::Update (Real elapsedTime, Keyboard *keyboard, Mouse *mouse) { … if ( keyboard->isKeyDown(KC_W) …)…. …} airplane.{h,c}

38. LevelManager • Sets up the world • Bubbles • Buildings • Format follows: int buildingPositions[MAX_LEVEL][MAX_BUILDINGS][6] = { … {//level 2 {5000, 0, 6000, 50, 950, 3000}, // x, y, z, width, height, length {10000, 0, 6000, 50, 950, 3000}, // 1 {6000, 0, 5000, 3000, 950, 50}, // 2 {6000, 0, 10000, 3000, 950, 50}, {6000, 1000, 6000, 3000, 50, 3000}, {0, 0, 0, 0, 0, 0}, // 5

41. Camera Controls if (mKeyboard->isKeyDown (KC_F1) && mExCamera) { mExCamera->SetTightness (1.0f); } else if (mKeyboard->isKeyDown (KC_F2) && mExCamera) { mExCamera->SetTightness (0.1f); } else if (mKeyboard->isKeyDown (KC_F3) && mExCamera) { mExCamera->SetTightness (0.05f); } else if (mKeyboard->isKeyDown (KC_F4) && mExCamera) …….. extended_frame_listener.cpp

42. Camera Controls

43. Sight & Sound • bind keys to toggle cockpit and sound • create guard variable to ensure only a single toggle per click

44. Toggle Cockpit F9

45. Toggle Cockpit Void ExtendedFrameListener::setTextArea(…Ogre::Overlay* olay){ overlay = olay; … } //toggle GUI if (mInputDevice->isKeyDown (KC_F9) && keyCountGUI >= 0.5) { if (overlay->isVisible()) { overlay->hide(); } else { overlay->show(); } keyCountGUI = 0; }

46. Toggle Sound (demonstration) F10

47. Toggle Sound if (mKeyboard->isKeyDown (KC_F10) && mChar && keyCountSound >= 0.5) { bool enabled; enabled = mChar->ToggleSound(); keyCountSound = 0; if (enabled) { status->setCaption("Sound Enabled"); } else { status->setCaption("Sound Disabled"); } } else if (keyCountSound >= 4.0) { status->setCaption(""); } void Airplane::toggleSound() { soundEnabled = !soundEnabled; musicSound.Mute(); if (soundEnabled) { if (crashed) { crashSound.Mute(); } else { engineSound.Play(); } } else { if (crashSoundStarted) { crashSound.Mute(); } else { engineSound.Stop(); } } }

48. Protection from Rapid-Fire • key press was registering every frame (up to 250 times per second) • Introduced timer to guard against this rapid-fire toggling • once toggle is registered, cannot be registered again for 0.5 second
