Memory Deduction Games

  1. 1. Brain Games Working with Arrays and Game Objects IT 7220 - March 9, 2009 Monday, March 9, 2009 1
  2. 2. Agenda Syllabus Updates ✦ A word about the Midterm ✦ Guest Lecturer March 23 ✦ Quick poll ✦ Greeting Cards ✦ Rosenzweig Chap 4 - Memory and Deduction ✦ Games HOT: Publishing in Flash; Perkins Chap 17 ✦ Lab and Group Work ✦ Monday, March 9, 2009 2
  3. 3. Midterm - March 23 Two Parts: ✦ An essay part where you will submit a ✦ Word document A Flash part where you will submit a Flash ✦ movie Monday, March 9, 2009 3
  4. 4. Guest Lecturer Dr. Moon-Heum Cho ✦ Candidate for our tenure-track faculty search ✦ Will talk for 1-hour before the exam ✦ Would like to know something about you ✦ Monday, March 9, 2009 4
  5. 5. Quick Poll By a show of hands: How many Doctoral students? ✦ How many Master’s students? ✦ How many EdSpec students? ✦ How many non-IT majors? ✦ Monday, March 9, 2009 5
  6. 6. Greeting Cards http://itlab2.coe.wayne.edu/tboileau/ IT7220WI09/GreetingCard/index.html Points Criterion available Create a greeting card using Flash 50 The card must include text and graphics 10 Provide a way to navigate back and forth between 15 pages (if a 2-page card) or replay (if an animation) Publish and upload the html & .swf files to our web 15 server Send the .fla file to me via Blackboard 10 Total 100 Monday, March 9, 2009 6
  7. 7. Rosenzweig Chap 4 Two game shell frameworks are provided: ✦ ✦ Simple memory game - player watches and repeats a sequence ✦ Deductive logic game - feedback is provided to get better on each turn Both frameworks rely on the use of data ✦ structures to keep track of game elements Principal data structures are arrays and objects ✦ Monday, March 9, 2009 7
  8. 8. Arrays as Data Structures Recall that an array in ActionScript is used to store a list of values; ex: a list of characters Arrays can store many types of objects including display ✦ objects such as movie clips and sprites (e.g., matching game in Chapter 3) You can also mix the types of types of values stored in arrays ✦ for example: [7, “Hello”] Arrays are a common and indispensable data structure for ✦ games Monday, March 9, 2009 8
  9. 9. Common Array Functions Function Example Description push myArray.push(“Wizard”) Adds a value to the end of an array Removes the last value of an array and pop myArray.pop() returns it unshift myarray.unshift(“Wizard”) Adds a value to the beginning of and array Removes the first value in an array and shift myArray.shift(“Wizard”) returns it myArray.splice(7,2,”Wizard”, Removes items from a location in the array splice ”Bard”) and inserts new items there Returns the location of an item, or -1 if it is indexOf myArray.indexOf(“Rogue”) not found sort myArray.sort() Sorts an array Monday, March 9, 2009 9
  10. 10. Data Objects Data objects are used when we need to keep track of (and store) multiple attributes in order to describe an object using dot syntax. An example in a game is character type, level and health Objects are dynamic: you can add new properties whenever you ✦ need to Properties can be of any variable type and do not need to be ✦ assigned; you just need to assign a value to them as in the example Monday, March 9, 2009 10
  11. 11. Data Objects and Arrays Data objects and arrays work well together ✦ Objects organize all of the attributes and ✦ methods needed to describe and use a thing Arrays help to organize and keep track of ✦ collections of objects in a game Monday, March 9, 2009 11
  12. 12. Memory Game Monday, March 9, 2009 12
  13. 13. Memory Game Source: http://www.freegames.ws/games/kidsgames/simon/simon.htm Monday, March 9, 2009 13
  14. 14. Memory Game MemoryGame.fla MemoryGame.as Monday, March 9, 2009 14
  15. 15. Memory Game ActionScript files (game class) are starting to ✦ get a little longer--this one is 167 lines Code is arranged in logical blocks ✦ Design rationale and description by ✦ Rosenzweig is provided in the text Tips for modifying the basic game are on page ✦ 137 Monday, March 9, 2009 15
  16. 16. Deduction Game Game concept comes from a 2- ✦ player board game Original concept dates back ✦ over a 100 years to a game called “Bulls and Cows” Object is to place five colored ✦ pegs in sequence to match a hidden pattern (code) using deductive logic Involves strategy to break the ✦ “code” in the least number of turns Monday, March 9, 2009 16
  17. 17. Other Deduction Games Monday, March 9, 2009 17
  18. 18. Deduction Game http://www.netrover.com/~jjrose/deduction/deduction.html Monday, March 9, 2009 18
  19. 19. Deduction Game Deduction.fla Deduction.as Monday, March 9, 2009 19
  20. 20. Deduction Game More robust strategy, similar to matching game i.e., ✦ 3 frames are used: intro, play, gameover Deduction game class contains about 200 lines of ✦ code Code is arranged in logical blocks ✦ Design rationale and description by Rosenzweig is ✦ provided in the text Game is modifiable to support use of different story ✦ lines and graphics in adventure game genre Monday, March 9, 2009 20
  21. 21. HOT: Publishing in Flash We have already talked ✦ about publish settings, under the file menu in Flash Flash allows for publishing ✦ content in a variety of options including: Web, CD, EXE/APP, QuickTime, and as image files Publish profiles can be ✦ created for different project types Monday, March 9, 2009 21
  22. 22. HOT: Publishing Formats Tabs available in publish ✦ settings are determined by the outputs selected Projector functionality is ✦ controlled using fscommand(), typically in first frame of movie (see exercise 3 p 476 and table on p 479) Monday, March 9, 2009 22
  23. 23. HOT: Publishing Flash Select “Top Down” load ✦ order to load layers from top--best practice is to place AS in top layer Select “Protect from import” ✦ to ‘discourage’ people from gaining access to your code “Generate size report” ✦ provides a frame-by-frame report of the size of all objects in your project Monday, March 9, 2009 23
  24. 24. HOT: Size Report Size report for Deduction.fla Monday, March 9, 2009 24
  25. 25. HOT: Publishing HTML Setting Dimensions to ✦ Percent allow the SWF file to scale with the HTML page it is opened within Setting Dimensions to ✦ Match Movie sets the HTML tags to the size of the stage Monday, March 9, 2009 25
  26. 26. HOT: Publishing Summary Flash provides the ability to export graphics as ✦ image files Publish settings are summarized on pp ✦ 484-493 Perkins provides guidelines for optimizing ✦ movies on pp 494-495 Monday, March 9, 2009 26
  27. 27. Lab and Group Work Monday, March 9, 2009 27
