- delete bin and obj directories/restart C#/rebuild
- documentation (variable dictionaries/program comments)-> demo by adding to Sandwich prg
(in Sel-Rep)
(2) Methods
Intro
- all subprograms, functions or procedures are called methods in C#
- Event handler methods vs user defined methods
- Why use -> songmethod (demo + then students use this version to create method )
- Using refactoring (right click highlighted code and extract method)

Flowcharting methods

Types of methods (private/public)
- void type
- type return
- with parameters

Examples
- simplemethods (windows app)
- counter (console app – note use of static)

- Extension (Optional)
- Having an event execute a method
- click lightning bolt in properties, find event you are interested in then type in method
name
- C# generates a method with name you specify
- it is possible to have one event handler respond to the same event on many different
controls
- Simple Example
- 3 buttons all using the same method
- Demo (RegForm)
- look at checkbox event CheckedChanged and RadioButtons event Click
- both point to ComputeCost_Changed
- The Sender Concept
- The list parameter pssed to any event handler is an object called sender
- This is actually the control that fired the event.
- By casting it to the appropriate object type you can interact with it just as you would
any
other control
- Demo (RadioButtons)

=> Methods Assignment (User defined methods) do first question with students (group assignment)

What is a class/object ****
- a description of a kind of object
- act a templates from which similar objects called instances are created

- when you want to create an object the new operator is used with the class name
or constructor (which have the same name as the class)
- creating an object is called instantiation/ every object is an instance of a class

- inheritance
- a way of incorporating all the methods and fields from one class into another
- eg. part time employee class (inherits from employee class)
- then adds new fields to extend the employee class

- Simple example -> buttons are objects of the button class in the toolbox

- border checking/ border disappearance (scroll effect)
- bouncing (Bouncing)

- Image Erasure Technique (ImageErasure)
- Why ? g.Clear(panel1.BackColor) vs FillRectange()
- reduce the size of the FillRectangle and observe results
RECORDED LESSON
=> Problem - Modify MovingFlipBook so that it animates using the ImageErasure technique
- you will need to convert images to transparent GIFs E-Learning Unit 12 Activity 3
- solution (DrawImageMovingFlipBook)

Collision Detection and Keyboard Events RECORDED LESSON
- looking at the 4 requirements for collision
- demo (CollisionDetectionDemo)

KeyBoard Events
- control must have focus to receive a keyboard event (panel cannot have focus must set focus on form in
Frm_Load )
- to detect keyboard events you need to set the forms KeyPreview to true (in properties)
- The KeyDown Event of Form (KeyBoardDetectionDemo)
- the property e.Keycode is used to determine which key is press down
- Keys.Right/Keys.Left
- FullyAnimatedKeyBoardDetection/FullAnimKeyBrdDetGrapBkg
- no pictureboxes used, everything is an image object, also using multi-colored bkg
Sound Effects
- playing sounds
- SoundDemo1
- need -> using System.Media/ add the Windows Media Player Control (COM
component)
- right click General/Items
- Load() stalls code until all audio loaded into mem/LoadAsync() loads on another thread
- SoundDemo2 (uses OpenFileDialog)

Sample Game (BeachBalls)/BeachBallsImageArray/BeachBallsImageArrayBkg (only fully explain last
example)

16) (5) Advanced Graphics and Animation E-Learning Unit 12, Activity 4

- DoubleBuffering RECORDED
LESSON
- Intro
- using SetStyle to double buffer (note placement in public Frm_)
- drawing is performed in a temporary off screen image
- after it completes the result is output to the screen
- double buffering reduces flicker caused by redrawing of controls
- only works for Paint event on component specified
- can work on a Panel also – but need to create a new class (see DynaGraphics)
- Examples
- Basic Animations
- Animation1 (remove double buffering lines and observe effect)
- note use of Using System.Drawing.Drawing2D
- note use of Invalidate() – forces a repaint (comment out observe)
- note this.CreateGraphics does not work here use e.Graphic
- Animation2 (multi-frame animation)
- Animation3 (keyboard movement + sound)
- Scrolling
- note use of this.DoubleBuffered=true

Form is 300 x 300 (each square
is one tile image of 100 x 100)
Colored area is all you see
(0-300x0-300) but off screen goes from –100 to 300
The program actually draws a larger image
For (int i=-100; i<400;I+=100)
For (int j=-100;j<400;j+=100)
g.DrawImage(background, x + i, y+j);
- stretch out form to get a peek behind the scenes
- comment if statements in DrawStuff() and observe results

- Mouse Movement
- Mouse
- note use of : this.DoubleBuffered=true; (New with VC#2005)
- note: use of timer for MouseDown (explosion)
-also note use of clientSize.Width and Height
- DynaGraphics
- double buffering on a panel

- Game Development
- The Basic Game Loop E-Learning Unit 12 Activity 5
- While (game is running)
Check for input (key/mouse)
Update all objects in the game (position)
Draw all the objects in the game
Refresh the screen (force a paint -> this.Invalidate())
- Sample Games (note use of Environment.TickCount)
- BabyGameKybrdVersion1/BabyGameKybrdVersion2/BabyGameMouseVersion
- SpaceShooterGame (note: use of ClientSize.Width/ClientSize.Height)

- note in BigGreenHead9 Color(r,g,b,opacity) (version 10 missing sound –
copy from V11)
- note in BigGreenHead11 use of arry of objects and foreach
=> Continue going through XNA101 Lessons

=> Review/Extension (KickingBaby1) – an array of Texture2D/also note Update() problem and use of
gameTime.ElapsedTime.TotalMilliSeconds
- demo how to convert sound code to XNA 3.1 SoundEffect class. Not possible for Song class – must be pure XNA 3.1

- drag to over temporarily
- inside button also uses two layers where 2nd layer adds hit state
- drag from over
- sample application (invisiblebuttonfinal.fla)

=> flash-creations.com + www.webwasp.co.uk/tutorials.index.php
(b) The Next Step ActionScripting AS3 E-Learning Unit 14
Activity 1
(1) Intro
- CS4 AS3 can only be placed in two places – Timeline/External AS Text File
- keyframes
- list of cmds that are executed as soon as the keyfrm is reached or a func
- Actionscript 2 migration see:
- www.senocular.com/flash/tutorials/as3withflashcs3
(2) Frame Actions (Timeline)
- put frame actions on separate layer
- Using actionscript to create non-linear movies (gotoAndPlay)
- make action that loops part of movie
(BeforeNonLinearMovie.fla/NonLinearMovie.fla)
- Using a frame label as the destination of a goto (NonLinearMovieUsingFrameLabel)

(3) Using Event Listeners with Buttons
- adding buttons to your animation to stop and continue playback RECORDED LESSON
- NewActionscriptPlayButtonAS3.fla
- note use of separate layer for frame actions
- note use of instance names
- name_btn (using this convention gives code hints use _mc for
mclips)
- name_btn.addEventListener(MouseEvent.CLICK,startit);
- note two types of functions
function say(e:MouseEvent):void { }
function add(n1:Number,n2:Number):Number{return n1+n2}
- click_to_play_as3.fla
- navigationAS3.fla (uses gotoAndStop)
- button_component_finished.fla (note difference between stop() and maps.stop() )
- label_finished.fla/tabbed_folders_finished.fla (uses mclips as btns)
- uses MOUSE_OVER/MOUSE_OUT/and currentLabel
- frame_labels_01.fla
- External Linking (url.fla/ActionScriptLinkButtonAS3.fla)
- make sure animated text initially added to btn is static text
- uses navigateToURL(new URLRequest(“http://www.yahoo.com”));

=> Minor Assignment (Four Box Problem)

(4) Putting it altogether E-Learning Unit 13 Activity 5
- (Brief Overview and demo) Not redone in AS3
- multiple scenes (add a new scene -> Window->Other Panels->Other Panels -> Scene)
- multiplescenes.fla
- note use of : gotoAndPlay(1,“scene 2”)) ** parameters reversed in AS3
- frame action (stop) must be on a keyframe
- Targeting scenes RECORDED LESSON
- duplicating scenes
- Examples (targetingscenes.fla/ gotoSceneFinal)

(5) Using Event Listeners with Movie Clips E-Learning Unit 14 Activity 2

- Intro
- NewMovieClipactionsAS3.fla (place another instance of eye on stage to compare)
- uses MouseEvent.MOUSE_DOWN and
MouseEvent.MOUSE_UP/OVER/OUT
- note naming convention: name_mc (use target in AS screen to choose
objects)

- NewMovieClipActionsInstanceNameAS3.fla (work thru similar example with
students)
- instancename.method -> eyeball_mc.play()/eyeball_mc.stop()
- note: (frame 1) eyeball_mc.stop() stops rotation/stop() stops movement
across
- changingimages.fla (note: use of mclip.gotoAndPlay(“frame”); (just demo ) in AS2
folder
- mcMouseOver.fla (see details below)
- note use of mclip.buttonMode=true (makes cursor switch to
finger)
- properties (no longer begin with underscore now box.x not box_.x)
- object property syntax -> object.property (theclip._alpha)
- where theclip is the instance name of the object
- some properties
.x (x pos), .y (y pos), .alpha (current alpha 0-1 ), .rotation (curr clip rot)
.width, .height, .mouseX,.mouseY, .scaleX, .scaleY
** .x,.y -> relate to registration pt of object left,top like in C# graphics
- only instances of button, clip and dynamic or input text can be changed during run
- Example
- propertiesAS3.fla
- eg. theclip.scaleX= -theclip.scaleX (performs horiz flip)
- note: +ve clockwise/-ve counter clockwise when using .rotation

- Nested Instances (paths to objects)
- Intro
- nestedAS3.fla (movie clip inside a movie clip- use double mc techn for
rectangle)
- then create circle symbol inside rect
- blue_mc.red_mc.x++;
- Practical Application
- NestedInstancesActionsAS3 (name front/back tires on main)

=> Minor Assignment (NestedInstancesProblem) also demo old version in AS2 folder

Additional Notes: (see mcMouseOver.fla above)
Basically illustrates how it is possible to use the same function for all movieclips passed to it by implementing
e.currentTarget

Circle_mc.addEventListener(MouseEvent.CLICK,fname);
Function fname(e:MouseEvent):void
{
e.currentTarget.alpha=.5;

}
recognizes movieclip that was passed

(6) Basic Actionscript Concepts

- variables (start off with simple example with students)
-using dynamic text and input text - show border and use naming convention –
>mytext_txt
*** New in CS4 can only use instance names (note use of .text property/parseInt( )/String( ) ***
- Examples
- must declare variables before use: var num:int / var num:Number (like double)
- math application ( NewestMathInputAS3.fla/ calculator-as3.fla )
- introduces .ToString() method just like C#
- .toFixed(2) formats to 2 decimal places
- incrementing a variable ( NewestVariables2AS3.fla)
- initialize counter outside of function for global scope
- LinkButtonAS3withVar.fla (optional)
- Dynamic Text (just demo)
- dynamicTxtAS3.fla/scrollingdynamicTxtAS3.fla
- note use of multi-line for dynamic text field
- illustrates loading external data
- uses URLLoader class
- Decisions E-Learning Unit 14 Activity 3
- intro ( NewestIf1AS3.fla) (note use of ==/ &&/||)
- Practical Application (cointoss)
- Math.random() -> 0-1/ (hi-lo+1)*Math.random()

(7) Advanced Actionscript Programming E-Learning Unit 15 Activity 1
RECORDED LESSON
- dragging a movie using startDrag()/stopDrag()
- true parameter causes shape to be picked up from its center
- drag1AS3.fla
- note use of e.target.startDrag()
- this allows function to be called from multiple objects as later illustrated below
- dragging and dropping
- dragdrop1AS3.fla
- note use of e.target.dropTarget!=null && e.target.dropTarget.parent=mclip
- practical application
- dragdrop_complete.fla
- see draganddropAS3.pdf for detailed instructions
- note target mclips on main stage have alpha set to 0
- they actually are the exact shape of holes
- note naming convention of mclips and targets
- note use of .removeEventListener

=> Traffic Signs Problem (due: day of practical test)

- Using Enter_Frame EventListeners E-Learning Unit 15 Activity 2
- hightlight concept of registration point when creating a mclip (default to top left)
- mc.addEventListener(Event.ENTER_FRAME,f)/function f (e:Event):void
- car1AS3.fla
- now .x, .y positions are located at the top,left position of an object like C#
- note the use of stage.stageWidth for wall detection
- car2AS3.fla
- note rotation calculation using inverse tangent
- randommovementAS3.fla
- if object moves away to quickly change fps or Math.random() >.9

- MouseInput.fla (tracks mouse movement using Event.ENTER_FRAME )
- mouseinputAS3.fla (mouseX/mouseY)
- note mouse positions are now top/left by default in reg
- do simple example to illustrate then discuss modification to have
illusion of movement control from center
- fox_mc.width/2
- frame_events.fla (note movie inside movie – wheel inside cycle)
- note difference between MOUSE_UP and MOUSE_OVER
- clock.fla (introduces getTimer() )
- customcursor.fla RECORDED LESSON
- note use of Mouse.hide()
-point_at_mouse.fla (note: math calc and functions/centre of rotation and reg point)
- Timer EventListeners
- intro
var myTimer:Timer = new Timer(10);
myTimer.addEventListener(TimerEvent.TIMER,f);
myTimer.start(); /myTimer.stop(); / function f (e:TimerEvent)
- car3AS3.fla/ timer_events.fla / stop_go_finished.fla (note use of Timer (400,1) )
delay,repeat

- Collision Detection
- hittestAS3.fla
- introduces hitTestObject(mclip) method to test for collisions
- discuss use of hitflag
- CollisionDetection.fla actual shape
- illustrates difference between hitTestObject and hitTestPoint(x,y,true)
- bouncingball.fla
- bouncing off mclip walls /note use of myTime.running
- Accepting keyboard input (attach EventListener to the stage)
- keyboardinput1AS3.fla (keyboard movement using KeyboardEvent.KEY_DOWN)
- function f (e:KeyboardEvent)
- keyboardinput2AS3.fla (incorporates ENTER_FRAME for smoother animation)
- Using the Sound Object (in Object Function folder) RECORDED LESSON
- triggering a sound from the library (soundAS3.fla) not on the timeline
- make sure to set its symbol linkage properties (right click in library)
- Export for AS and put name in class
- note use of SoundChannel class to stop sounds
- bounceAS3.fla
- uses multiple instances of mclip with embedded actions

Hint: create a chasing game incorporating ideas from randommovementAS3.fla/clock.fla
/hittestAS3.fla/keyboardinput2AS3.fla

- Recap Example (in EnterFrame folder)
- events.fla
- red box mclip has frame by frame animation embedded in it, also draggable
- the wheel has an embedded motion tween rotation
- the green box mclip is also draggable / the red oval is a button rotates the red box
- pressing keydown activates embedded red box frame by frame animation and tire
- a basic ENTER_FRAME move bike and TimerEvent rotates wheel
WORK PERIOD/REVIEW PERIOD
=> Practical Test

Building a Game E-Learning Unit 15 Activity 4
- Resources: FlashAS3GamePrgTutorial RECORDED LESSON
Books (Foundation Game Design/AS3 Game Prg U)
- Dynamically adding and removing Objects (do basic intro with students)
- movieclip must already exist in library with Class name
var fred:Smiley= new Smiley();
fred.x=200;/fred.y=300;
addChild(fred)/removeChild(fred);
- Examples
- DynamicObjects1AS3.fla (creating/removing a single object)
- DynamicObjects2AS3.fla (creating multiple objects)
- DynamicObjects3AS3.fla (moving a dynamic object)
- DynamicObjects4AS3.fla (moving an animated dynamic object)
- SpriteMovement.fla (moving an object referencing
.currentFrame)
- followhand.fla
- object points in same direction as mouse position
- uses functions that return values (not void)
- DynamicObjects5AS3.fla
- moving a dynamic object using the keyboard
- very smooth movement
- compare method to keyboardinput1/2AS3
- Controlling multiple movie clips
- need to use Arrays (demo using trace (myArray) )
var myArray:Array = new Array();
= new Array(“1”,”2”);
myArray[0]=”1”;
myArray.push(“3”); adds new element to end of array
myArray.splice(i,1) del from pos I one item – all items slide up array shrinks
myArray.length;
for (var i:int=0;i<myArray.length;i++)
Examples
- DynamicObjects6AS3.fla
- initially similar to DynamicObjects2AS3 where we
created multiple mclips in a for loop BUT now we must
access these clips after they are added to the screen and
change certain properties. This is where the use of
of Arrays come in.
- comment out cogs.push and drop timer to prove pt
var cogs:Array = new Array();
for (var i:int =0;i<10;i+=)
{
var newcog:Cog = new Cog();
cogs.push(newcog);
newcog.x=i*50+50;
newcog.y=100;
addChild(newcog);
}
for (var i:int =0;i<10;i+=)
cogs[i].y+=5;
- DynamicObjects7AS3.fla (simple hunt and click game)
- note use of
addEventListener(MouseEvent.MOUSE_DOWN,hit)
- NOT connected to a button or mclip but rather the stage
- uses second method of hitTest
- you feed it the location of a pt ***
- object.hitTestPoint(mouseX,mouseY,true)
- last para determines whether flash uses the bounding
box around the mc as the area for collision detection or
the exact shape (true means use exact shape)
- change to false to illustrate difference
=> Minor Assignment (create a simple game similar to DynamicObjects7AS3.fla) –add extra features (explosion,custom
cursor)
