SWF::Builder::ActionScript - SWF ActionScript object.
$mc->frame_action(1)->compile( <<AS_END ); function move_mc(dx) { this._x += dx; } AS_END my $mc_i = $mc->place; $mc_i->on('KeyPress', '<Left>')->compile('move_mc(-5)'); $mc_i->on('KeyPress', '<Right>')->compile('move_mc(5)'); $mc_i->on('EnterFrame')->r_rotate(15);
SWF::Builder::ActionScript supports some simple actions and compiling ActionScript compatible with FlashMX.
Methods for movie clip to create a frame action and a clip action. These return an SWF::Builder::ActionSctipt object.
creates a frame action.
creates a clip action. See SWF::Builder::MovieClip for details of the events.
These method add some simple actions to $as and return $as itself.
tells the flash player to go to $frame.
tells the flash player to go to $frame and stop playing.
tells the flash player to play the movie clip.
tells the flash player to stop playing the movie clip.
sets a movie clip property.
moves the movie clip to ($x, $y).
moves the movie clip to (current X + $dx, current Y + $dy).
rotates the movie clip toward $r degree absolutely.
rotates the movie clip to +$dr degree right.
magnifies/reduces the movie clip.
shows the movie clip.
hides the movie clip.
changes the target movie clip for actions in &actionsub. $target is a target path string or a named movie clip instance. &actionsub is called with an ActionScript object whose target is changed. For example,
$mc_i->on('Press')->tellTarget( $mc_i2, sub { shift->r_rotate(15); });
rotates $mc_i2 to 15-degree right when $mc_i is clicked.
SWF::Builder::ActionScript has a FlashMX-compatible compiler for complex actions.
compiles $script_text. Options are as follows:
controls optimization.
bit 0: peephole optimization 1: calculate constant expressions 2: calculate math funcions with constant args and constant properties 3: evaluate a lefthand side of an assignment expression only once
Default is all on.
ATTENTION: FlashMX ActionScript compiler seems to evaluate a lefthand side of a compound assignment operator twice, while ECMA-262 provides to evaluate it once. For example, FlashMX compiles 'a[i++] += 2' as same as 'a[i++] = a[i++] + 2', which counts up i twice. Optimize bit 3 controls this. If you want the same as FlashMX, reset bit 3.
tells the compiler how to compile 'trace' action.
ignore all trace action.
evaluate the parameters of a trace action, but don't output anything. This is default.
output the value to another movie via a LocalConnection. You can use 'tracewindow.swf' at scripts directory as output window.
use ActionTrace tag.
sets the warning level.
0: deplicated actions. 1: useless operator in void context. 2: future reserved and other unsupported feature.
loads a script and compiles it. See compile method for %options.
Pragmas are not supported.
The compiler evaluates a lefthand side of an assignment expression once by default. See Optimize option.
