PHP ʖ²ἯTH º󍋼/A SWFAction Description ¾¯¸漯B swfaction() creates a new Action, and compiles the given script into an SWFAction object. So what's left? The compiler recognises the following tokens: break for continue if else do while There is no typed data; all values in the SWF action machine are stored as strings. The following functions can be used in expressions: Returns the number of milliseconds (?) elapsed since the movie started. Returns a pseudo-random number in the range 0-seed. Returns the length of the given expression. Returns the given number rounded down to the nearest integer. Returns the concatenation of the given expressions. Returns the ASCII code for the given character Returns the character for the given ASCII code Returns the substring of length length at location location of the given string string. Additionally, the following commands may be used: Duplicate the named movie clip (aka sprite). The new movie clip has name name and is at depth depth. Removes the named movie clip. Write the given expression to the trace log. Doubtful that the browser plugin does anything with this. Start dragging the movie clip target. The lock argument indicates whether to lock the mouse (?)- use 0 (FALSE) or 1 (TRUE). Optional parameters define a bounding area for the dragging. Stop dragging my heart around. And this movie clip, too. Call the named frame as a function. Load the given URL into the named target. The target argument corresponds to HTML document targets (such as "_top" or "_blank"). The optional method argument can be POST or GET if you want to submit variables back to the server. Load the given URL into the named target. The target argument can be a frame name (I think), or one of the magical values "_level0" (replaces current movie) or "_level1" (loads new movie on top of current movie). Go to the next frame. Go to the last (or, rather, previous) frame. Start playing the movie. Stop playing the movie. Toggle between high and low quality. Stop playing all sounds. Go to frame number num. Frame numbers start at 0. Go to the frame named name. Which does a lot of good, since I haven't added frame labels yet. Sets the context for action. Or so they say- I really have no idea what this does. x y xScale yScale currentFrame - (read-only) totalFrames - (read-only) alpha - transparency level visible - 1=on, 0=off (?) width - (read-only) height - (read-only) rotation target - (read-only) (???) framesLoaded - (read-only) name dropTarget - (read-only) (???) url - (read-only) (???) highQuality - 1=high, 0=low (?) focusRect - (???) soundBufTime - (???) =ד 1. swfaction() example ?php $s = new SWFShape(); $f = $s- addFill(0xff, 0, 0); $s- setRightFill($f); $s- movePenTo(-500,-500); $s- drawLineTo(500,-500); $s- drawLineTo(500,500); $s- drawLineTo(-500,500); $s- drawLineTo(-500,-500); $p = new SWFSprite(); $i = $p- add($s); $i- setDepth(1); $p- nextFrame(); for($n=0; $n 5; ++$n) {$i- rotate(-15); $p- nextFrame();} $m = new SWFMovie(); $m- setBackground(0xff, 0xff, 0xff); $m- setDimension(6000,4000); $i = $m- add($p); $i- setDepth(1); $i- moveTo(-500,2000); $i- setName("box"); $m- add(new SWFAction("/box.x += 3;")); $m- nextFrame(); $m- add(new SWFAction("gotoFrame(0); play();")); $m- nextFrame(); header('Content-type: application/x-shockwave-flash'); $m- output();? =ד 2. swfaction() example ?php $m = new SWFMovie(); $m- setRate(36.0); $m- setDimension(1200, 800); $m- setBackground(0, 0, 0); /* mouse tracking sprite - empty, but follows mouse so we can get its x and y coordinates */ $i = $m- add(new SWFSprite()); $i- setName('mouse'); $m- add(new SWFAction(" startDrag('/mouse', 1); /* '1' means lock sprite to the mouse */ ")); /* might as well turn off antialiasing, since these are just squares. */ $m- add(new SWFAction(" this.quality = 0; ")); /* morphing box */ $r = new SWFMorph(); $s = $r- getShape1(); /* Note this is backwards from normal shapes.
