| ==adventure games' formula==
| |
| * take a popular fiction game. E.g. a detective novel/
| |
| * create:
| |
| ** a background story
| |
| ** a map for the players to move around it
| |
| ** objects to manipulate
| |
| ** characters to interact with
| |
| ** '''a plot tree with several outcomes'''
| |
|
| |
| [[File:game-map.svg|thumb|Plot tree]]
| |
|
| |
| * add: descriptions, dialogues, error messages and a vocabulary for the players
| |
|
| |
| ''game development then becomes much like planning and writing a piece of short fiction, except multiple outcomes must be conceived''.

| ==the city==
| |
| Can we create a web-based game, that can played within the physical space of the city, using mobile phones?
| |
|
| |
| The city game can become a way of exploring a space, a city, an excuse to drift (dérive), experience and perceive the city differently from our day-to-day understanding of it.

| ===discussion===
| |
| How is this game constructed?
| |
| * '''scenes'''; Each scene contains:
| |
| ** number. E.g. <code>scene_2</code>
| |
| ** title
| |
| ** msg
| |
| ** img (option),
| |
| ** question
| |
| ** connect(ing scenes)
| |
|
| |
| * html template (empty tags) that are replace as the game progresses
| |
|
| |
| What can be changed in this game?
| |
|
| |
| === assignment===
| |
| Design a new game, that has to although existing in the Internet, has to interfere with real-life.
| |
|
| |
| It has to interfere with the real world, the physical reality of the player.
| |
|
| |
| The game should help the player discover the space of the square: the details, sounds, movements, the people.
| |
|
| |
| Keep it simple.
| |
| Have fun!

| ==Adventure: with text user input==
| |
| '''The same adventure, but with added user input interaction'''
| |
|
| |
| === Code explained ===
| |
| The HTML page is divided in 2 divs:
| |
| * $('div#form') - a div w/ a form that receives user input
| |
| * $('div#scene') - a div that contains text, image and buttons for each scene
| |
|
| |
| On start:
| |
| * $('div#form') is SHOWN.
| |
| * $('div#scene') is HIDDEN (css display:none)
| |
|
| |
| On $("form#userQuestions").submit():
| |
| * userName, userLocation are STORED and REPLACE in scenes object %%userName%% and %%location%%
| |
| * $('div#scene') is FILLED with values from scene_1, with the FUNCTION: replace_scene('scene_1');
| |
| * $('div#form') is HIDDEN.
| |
| * $('div#scene') is SHOWN (css display:block)
| |
|
| |
| User is on scene 1:
| |
| * every time the user CLICKS a button: $("button").click()
| |
| ** a next_scene is CREATED from the clicked button 'name' attribute
| |
| ** replace_scene() for the next_scene
