Programming games Cannonball due. Drawing & printing example. Acquiring video or sound Homework: Catch up: complete projects (rps, Bo, cb). Start video or audio. Plan your project.

Cannonball extension You may consider adding sound to cannonball for your sound/video project. Can use –coding or –sound in frame

Flash terms Create.fla and.as files using Flash development environment. This is development time. Runtime (aka execution time) –Test program using the development environment. This does create a.swf file. –Publish creates.html file and.swf file

Development time Bring instances of movie clip symbols in Library to the Stage. –Give instance names –ActionScript refers to instances by name Can File/Print –May not do what you want… –I copy and paste code into Word or Dreamweaver

Drawing & printing Adding content, namely a movie clip symbol to Stage at runtime –Various calculations –Use Properties of symbol (right mouse click) to set up: Export for ActionScript Print during runtime –Can set up to print several pages. My example just prints one page.

Demonstrate Drawing example Note: this is a ‘stub’ for a bigger application.

Features Create wall symbol. Change settings to Export for ActionScript. Set up handling for mouse click on board. –One handler for 1 st click and another for 2 nd click –Use ev.localX and ev.localY to get coordinates. –Use Math.atan2(…) and Point.distance(…) Use PrintJob

Making your own video for Flash playback Shoot video Upload to computer [Edit] Produce.flv Create Flash movie and test Publish Flash movie –Upload.html,.swf, and all the.flv files to the server

Initial steps Shoot (?) video Upload to computer

Producing.flv Just like images, there are different encodings for videos. –wmv, mov, avi, dv, …. Adobe Flash CS4 Media Encoder will accept many different types and produce an.flv file (an.flv version of the same video clip) –Can set quality settings Tradeoff: size (space on server, loading time) versus quality

Start queue Creating the.flv file takes a while…. You can do more than one encoding at a time. –The name of each file is the same name, with filetype.flv Use the pre-set settings OR get into more detail –Higher quality means larger files

Acquire video Find website with video (or audio) go to –Enter URL of site –Check off agree to terms, filter (movies or audio) –click on get files –be patient –choose from list.

Sound Two (at least) methods for incorporating sound into Flash All coding: create Sound objects, set source of sound, play. Can manipulate volume, pan, etc. using Soundchannel. Also, register and handle events, including when sound has been loaded. Frame: associate [start of] sound with frame.

Acquire sound Many types of sound. For coding method, need mp3 Find on-line sound editors. Need to know location (URL) of sound file(s).

Coding method import flash.media.Sound; import flash.net.URLRequest; var urlname:String = "missle.mp3"; var requestsf:URLRequest = new URLRequest(urlname); var msound:Sound = new Sound(requestsf); // at appropriate place in the code msound.play(); This file is located in the same folder on my computer. It doesn't have to be.

Frame method File/Import/Import to Library –Select sound file(s). Click on appropriate frame in timeline In property panel, select Sound [file]. –You can select a set effect and/or edit the sound.

Cautions In either method, need to be aware that sound lasts certain amount of time. Be careful about starting sound again and again (unless that is what you want)

Examine source Sound added to frame –Bo the barking dog –consider for collapsing/exploding target Code –Play sound as event handler for button click –Play random choice of tune from [short] list. Note: pause, pan, volume features. These require other objects.

Homework Decide on video or audio –Create or acquire video clip(s) –Create or acquire audio clips. Can use Common Library / sounds. –Keep in mind: this is a short assignment. –You can incorporate sound or video into your final project. Think about what you want to do for your project –Check with me AND make proposal to blog.
