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.

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.

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 OgreCharacterupdate(elapsedTime,
  input) void
• post self.raySceneQuery-gtforAll(
  worldFragment.singleIntersection.y lt
  self.mMainNode.getPosition().y )

18
OCL

• The FMOD sound system shouldn't be re-initialized
• context CFModInitSoundSystem() bool
• pre self.initialized false
• post self.initialized true

19
OCL

• The bubbles and buildings must be within the
  boundaries of the world
• context SampleApplicationcreateScene() void
• post self.buildings.getBoundingBox-gtforAll( getM
  inimum.x gt 0 and getMinimum.z gt 0 and
  getMaximum.x lt 10000 and getMaximum.z lt
  10000 )
• post self.bubbles.getBoundingBox-gtforAll( getMin
  imum.x gt 0 and getMinimum.z gt 0 and
  getMaximum.x lt 10000 and getMaximum.z lt
  10000 )

OCL

• Checking the win-condition for a level --
  theoretically we would load a new level after
  hitting all targets
• context OgreCharactertargetsRemaining() int
• result self.targetHit-gtcount(false)
• context OgreCharactercheckWin() bool
• result self.targetsRemaining 0
• context SampleListenerframeStarted(frameEvent)
  void
• post self.mChar.checkWin false

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
  years team with updated code. ?

37
Wheres the Keyboard?
using namespace OIS void AirplaneUpdate (Real
elapsedTime, Keyboard keyboard, Mouse mouse)
if ( keyboard-gtisKeyDown(KC_W) ).
airplane.h,c
38
LevelManager

• Sets up the world
• Bubbles
• Buildings
• Format follows
• int buildingPositionsMAX_LEVELMAX_BUILDINGS6
  
• //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

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 ExtendedFrameListenersetTextArea(OgreOve
  rlay olay)
• overlay olay
• //toggle GUI
• if (mInputDevice-gtisKeyDown (KC_F9)
  keyCountGUI gt 0.5)
• if (overlay-gtisVisible())
• overlay-gthide()
• else
• overlay-gtshow()
• keyCountGUI 0

46
Toggle Sound
F10

• (demonstration)

47
Toggle Sound

• if (mKeyboard-gtisKeyDown (KC_F10) mChar
  keyCountSound gt 0.5)
• bool enabled
• enabled mChar-gtToggleSound()
• keyCountSound 0
• if (enabled)
• status-gtsetCaption("Sound Enabled")
• else
• status-gtsetCaption("Sound Disabled")
• else if (keyCountSound gt 4.0)
• status-gtsetCaption("")

void AirplanetoggleSound() 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
