DESCRIPTION

Dive into Greenfoot game design by reviewing unique games that combine action and strategy. Learn about the aims, characters, inputs, controls, game rules, and the structure of various levels. Examine the mechanics of converting carbon dioxide into oxygen in action-based gameplay and the strategic challenge of trash collection within a time constraint.

Presentation Transcript

  1. Planning

  2. Reviewing Greenfoot games • Play 3 Greenfoot games and make notes about the following: • Aims of the game • Characters: • Inputs/Controls • Rules of the game • Levels • Variables

  3. Global Men • Has two separate parts to the game so far:Action Game Part: - Turning carbon dioxide molecules into two oxygen molecules and a carbon molecule by special equipment- Becoming familiar with the controlsStrategy Platform Part:- Collecting trash in a limited time frame- Figuring out the invisible maze in the map using the visuals as cluesControls (In case no one cares to read the tutorial)Left Movement ? Left Key, ARight Movement ? Right Key, DJump ? Up Key, W, SpacebarUse Handheld Protonic Equipment ? JUse Ranged Protonic Equipment ? K • http://www.greenfoot.org/scenarios/1033

  4. Glacier Defence • Defend one of the polar ice caps from our pollution, in a 20-wave strategy-based game! • http://www.greenfoot.org/scenarios/1094

  5. Animal Diet • This is a game made for a school project. The idea was to make something educational. “I didn't have much time to work on it, but I consider this to be just a PROTOTYPE and I'll keep working on it as soon as I have some free time. ““I'll also work on the game art and by the time I'm done it will look much different.”http://www.greenfoot.org/scenarios/3768

  6. MIND MAP Gaming Ideas • Type of game (maze, platform, shooter) • Theme/background • Characters • Inputs/ controls • Rules of the game • Levels/Missions • Variables

  7. Creating your game • Use Fireworks to make all the: • characters/actors /objects • Backgrounds • Intro screen • Gameover screen • Collect sound effects – findsounds.com

  8. Storyboarding • http://dogtrax.edublogs.org/2011/12/16/more-video-game-storyboarding-the-student-perspective/ • http://www.youtube.com/watch?v=k-9pkB05IlQ • http://www.youtube.com/watch?v=3fk0uWer6IQ • http://www.youtube.com/watch?v=Q10ZO-8ByAc

  9. Actors Name for your game Levels Inputs Aims/Rules What variables? Write about sound effects Choose an environment

  10. Rule Planning Events Actions • Right/left click • Left/right/up/down arrow • Space Bar • Lives = 0 • Collision with another object (state the object) • Point in Direction (north, south, east, west) • Move (number of steps) • Set Location (x, y) • Rotate (degrees) • Change score – increase or decrease • Change lives • Change Y or X position • Remove/show • Play sound

  11. Inputs, processing, outputs Planning

  12. Success Criteria • Calculate the ….. • Display ………..on the screen • Be able to know the end of the game…. • Start game…. • Know that level/score/time the player is on • Fun to play… • Good graphics…

  13. What makes a good game? • Is it fun to play? • Does it have different levels? • Does it keeps a score? • Can you can play with friends? (multiplayer) • Does it have a point? – story or narrative • Does it have good quality graphics? – backgrounds & characters • Does it have a goal or task? • Is it easy to play? • Does it use suitable sound & music? • Does it have easy to use controls? • Do you like the characters? • Is there enough help and guidance?

  14. Algorithms Planning • Using Pseudo code descriptions

  15. Programming Tools: • Defining inputs/process/outputs • Flowchart • Pseudocode Chapter 2- Visual Basic Schneider

  16. Inputs/Process/output table

  17. What is a flowchart? • Logic diagram to describe each step that the program must perform to arrive at the solution. • A popular logic tool used for showing an algorithm in graphics form. Chapter 2- Visual Basic Schneider

  18. Continue flowchart • Programmer prepares flowchart before coding. • Most common flowchart symbols are: Start Selection/ decision Process Input / output Chapter 2- Visual Basic Schneider

  19. Purpose of Flowcharting: • An aid in developing the logic of a program. • Verification that all possible conditions have been considered in a program. • Provides means of communication with others about the program. • A guide in coding the program. • Documentation for the program. Chapter 2- Visual Basic Schneider

  20. Example of Flowchart to show changing the score Start Initialize Score counter = 0 If Collides with Asteroid No Yes Current Score Increment score Display Score

  21. Desk Checking • The process of testing the flowchart with different data as input, and checking the output. • The test data should include nonstandard data as well as typical data. Chapter 2- Visual Basic Schneider

  22. What is a Pseudocode? • A program design technique that uses English words. • Has no formal syntactical rules. Chapter 2- Visual Basic Schneider

  23. Example of Pseudocode: • Determine the average grade of a class: Declare variable score Set score variable to 0 If spaceship collides with the asteroid Get the current score Increment the score Output/display new score on the stage
