  1. Programming games Flash concepts. Coin toss. Filezilla: upload your project(s) Homework: Enjoy Spring Break.

  2. Flash • Environment for creating and testing Flash application • including writing code and creating graphics • When you are done, you PUBLISH to produce a pair of files: .swf and .html. • Many features in Flash: more than we will do.

  3. ActionScript 3.0. • We will NOT do ActionScript 2.0. • Significant changes in the language.

  4. Flash features • Stage • Timeline • frames • layers • Properties panel • Tool panel • Window/Actions: where you write code for a layer of a frame in a timeline.

  5. Flash object • Movie clip • Timeline: 1 to any number of frames • code in any frame • Note: many of our movie clip symbols will have just one frame. • Button • 4 frames: up, over, down, hit • Graphics • We mainly will create movie clip symbols and place instances of them on the Stage at specific frames.

  6. Coin toss • Create 2 movie clip symbols and move instances to the Stage and NAME INSTANCES. • head • tail • Look at Window/common libraries/buttons and get a button • alter this button to display FLIP. • name the button instance • Write code in the [only] frame of the main movie (Scene 1) to • set up event handling for hitting the button • simulating random coin toss by making either head or tail visible and the other not visible.

  7. Techniques • Use rectangle/oval tool and keep shift key down to make a circle. • In Library panel, right click on head, duplicate, rename tail to get same size. • Use segmentation to erase parts… • Change magnification to make larger to ease drawing.

  8. NAME things • Move instances of symbols to Stage. • You need to give the instances names in order to reference them in ActionScript. • While selected, in Properties panel, give a name. • It can be the same as the movie clip symbol name. In some applications, you may have more than one.

  9. Buttons • I will show you 3 ways to make buttons. • common library • do it yourself (rock paper scissors) • components • This is Common Library way. Need to change Enter to Flip.

  10. Change symbol in Library

  11. Changing text… • Need to unlock the text layer • Pick up T tool • make change • return to Scene 1

  12. Notice • When you change something in the Library, all instances of it change on the Stage. • Need to give the button instance on Stage a name: flipbtn.

  13. Add coding • Click off of any object so nothing is selected. • Windows/Actions • Write code

  14. Testing • Go to Control/Test movie/In Flash Professional • When it works, File/Save As

  15. Improvement • Keep track of counts of heads and tails. • Create 2 TLF read only and 2 selectable text fields • Expand Character panel to change size and font and other features. • Use x and y in Properties panel to line up. • Name the selectable text fields. • Modify code.

  16. 2 + 2 text fields

  17. Changing code • The text in the text field must be changed to a number before adding 1 to it and then changed back to text. • The text is referenced using the name of the text field with .text

  18. Homework • [Finish and show coin toss with counts. Add anything else you want.] • Enjoy break! • You can do tutorials, practice drawing. • You can look ahead to rock-paper-scissors, Bo the barking dog, etc.
