This document provides guidance and challenges for designing and building a space shooter game. The previous challenge was to design and build the basic mechanics of a space shooter using provided assets. The current challenge is to expand that game by adding features like multiple lives, saving and restoring gameplay, and an ending or reward. It also provides guidance on pitching game ideas to peers by outlining what to include in the pitch and feedback. The document then contrasts using drag and drop forms versus coding in GameMaker Language, and provides examples of functions and variables that can add complexity. It concludes by discussing concepts like flow and choice that can enhance narrative gameplay.

Week 4 Decisions & Flow
- 1. Decisions PITCHING & SWOT FEEDBACK GML FLOW AND CHOICE
- 2. Challenge LAST WEEK Design and build a Space-Shooter game Use the provided collection of assets and mechanics to design and build a space-shooter game. Assets include space ships, asteroids, planets, backgrounds and aliens. Mechanics include controlling free movement of an object on screen, random generation of objects, floating across the screen, firing bullets or lasers, breaking an object into pieces, and explosions. THIS WEEK Top & Tail the Space-Shooter game Challenge 1 produced the mechanics and gameplay for a space-shooter. You should now use that structure to create a space-shooter game. A player should be able to start, quit, save and restore the game. They should have multiple lives to allow them to survive, and there should be an end to the game with some form of reward for or acknowledgement of success.
- 3. Pitches Present your game idea to a small group (4-5) of other students Speak about your idea for 3 minutes Draw on paper or show images on screen if it helps Bring a copy of the proposal to help you Include the aesthetic, dynamic and mechanics Use references and other games to establish the idea in your audience’s mind Explain your tagline Respond as part of group to other pitches for up to 2 minutes Provide written feedback to each pitch Strengths: Any element of the idea that caught your attention and you liked Weaknesses: Anything they might want to cut out of the idea or that they could fix Opportunities: Anything you think could be added to the idea – missing elements Threats: What could go wrong
- 4. GML: Forms vs Code
- 5. Action Equivalents All the actions in the Drag and Drop are available as code equivalents
- 6. GameMaker Language (GML) Code is easier to read and understand Code allows complex actions Code is managed as the forms were, attached to events Variable: a word that stores a number or word Variables hold property values (speed, direction, etc) and can be changed by code Functions: Commands that to do something (like destroy an instance or change rooms) or that return a value (like which key was pressed)
- 8. keyboard_check() arguments vk_nokey keycode representing that no key is pressed vk_anykey keycode representing that any key is pressed vk_left keycode for left arrow key vk_right keycode for right arrow key vk_up keycode for up arrow key vk_down keycode for down arrow key vk_enter enter key vk_escape escape key vk_space space key vk_shift either of the shift keys vk_control either of the control keys vk_alt alt key
- 9. Added functionality ROOM VARIABLES room_exists room_first room_last room_next room_previous room ROOMS IN ACTION room_speed room_height room_width room_persistent room_caption room_get_name room_goto room_goto_next room_goto_previous room_restart
- 10. Flow and choice
- 11. Flow A challenging activity that requires skill Activity provides clear goals and feedback The outcome is uncertain but can be influenced by your actions Csikszentmihalyi, Mihaly (1990). Flow – The psychology of optimal experience. London: Harper
- 12. Effects of Flow A merging of action and awareness: spontaneous, automatic action/reaction Concentration on immediate task without mind wandering: focus on here-and-now Loss of awareness of self, of ego – at one with the situation Distorted sense of time (game time slows down, real time speeds up) Experience of the activity becomes an end in itself

- 22. Decisions: Value judgements Resource trades. You give one thing up in exchange for another, where both are valuable. Risk versus reward. One choice is safe. The other choice has a potentially greater payoff, but also a higher risk of failure. Choice of actions. You have several potential things you can do, but you can’t do them all. The player must choose the actions that they feel are the most important at the time. Short term versus long term. You can have something right now, or something better later on. The player must balance immediate needs against long-term goals. Dilemmas. You must give up one of several things. Which one can you most afford to lose? Meaningless decisions Obvious decisions Blind decisions
