actionscript, that infuriatingly intractable marshmellow fluff... so far i have only understood the most basic of concepts, but now i will try to learn it well.
Contents
trace
var message = "Hi there"; trace (message); // prints "Hi there"
var message = "yellow"; trace ("big " + message + " truck"); // prints "big yellow truck"
conditionals
var message = "yellow"; trace ("big " + message + " truck"); // prints "big yellow truck" if (message == "yellow") { trace ("yes, i did say big yellow truck."); // prints "yes, i did say big yellow truck" }
loops
this sequence... trace (101); trace (102); trace (103); trace (104); trace (105); |
is equal to:
var x = 101; trace (x); x = x + 1; trace (x); x = x + 1; trace (x); x = x + 1; trace (x); x = x + 1; trace (x); |
is also equal to:
var x = 101; while (x <= 105) { // as long as x is less than 105... trace (x); x = x + 1; // ...continue to trace x but add one each time } |
they all print:
101 102 103 104 105 |
functions
sample:
function area(height, width){ return height * width; } area1 = area(10,15); area2 = area(10,20); area3 = area(10,20);
event based execution
someObject.onSomeEvent = someFunction;
for example:
skaGirl.onRelease = dirtyskanking; // the object named skaGirl will dirtyskank when mouse is released function dirtyskanking () { this._parent._rotation = 360; // defines the rotation of the dirtyskanking. }
sample
quiz
button1.onRelease = function () { // on pressing button 1 this._parent.q1answer = 1; // assigning 1 to q1 answer this._parent.gotoAndStop("q2") // after which we go to frame labelled as q2 }
tips
- use frame labels rather than frame numbers. a starting frame could be init.
