It's weakness-it's mostly useless on its own.Let's take a look at some examples.First,let's start with two rectangular shapes and push them together.A new file,two rectangles converted to symbols,given instance names of rect1 and rect2 and a dynamic text field named txt_hit.Frame 1 gets this code: This means you can have many objects using this hitTest-ing at frame rate. Simple and Easy Its strength-it's light and doesn't really require much math and as such is barely noticeable processor-wise. It's mainly oriented to flash game developers, but anyone who bumps stuff in flash can find use of it. But unless you'll be pushing rectangular shapes without any rotation into each other, it won't do much work. The main method for Collision Detection in flash is using hitTestObject. Test to see if every element in an array of numbers is less than 7 with Array.This is intended to introduce all collision detection principles in flash, their strengths, weaknesses and workarounds. This test method should have a Boolean for a return type. The method which contains the test criteria will accept three arguments, an element of the array, the index of that particular element, and a reference to the array itself. Each method will return a Boolean true or false depending on whether or not the specified criteria is met. What: These two methods accept two parameters, the name of a method to call which will specify your test criteria and an (optional) object which defines the scope in which the method resides. Search for a nonexistent element with Array.indexOf():ĮVERY/SOME: when: You want to determine if every (Array.every()) or at least one (Array.some()) element in an array meets certain criteria. Private var _testArray:Array = new Array(5, 6, 7, 8, 9, 8, 7, 6) įind the index value of 7 in an array of numbers with Array.lastIndexOf(): While indexOf() will start searching at the beginning of the array and return the index number of the first found element, lastIndexOf() will start searching at the end of the array and return the index number of the first found element (working backwards).įind the index value of 7 in an array of numbers with Array.indexOf(): The methods will return an integer value which is either the index number of the found element or a -1 if the element is not found. These methods take two arguments, a value to search for and a (optional) beginning index number. The latest version, ActionScript 3.0, released together with Flash CS3, emphasizes. Calling the API functions, can easily be done. ActionScript is similar to JavaScript with its syntax and functionality. SWC file to the libs folder of your flex project. What: These two methods work much the same way String.indexOf() works. I just ported the service to an ActionScript 3.0 API to open it up for other Flash and Flex developers Get your SWC library here. INDEXOF/LASTINDEXOF: when: You want to determine if an array contains a specified element.
#FLASH ACTIONSCRIPT 3.0 METHODS HOW TO#
This is just a quick look at what these new Array methods do and when and how to use them. Undocumented in the Flex 2 documentation, they have now been disclosed in the revamped Adobe Actionscript 3 livedocs. In addition to those, Actionscript 3 provides seven new very powerful methods to consider: every(), filter(), forEach(), indexOf(), lastIndexOf(), map(), and some(). In it, youll find a schematic guide to using. Thats where this video tutorial comes in. But having the program isnt enough you need to know how to use it. It is ideal for interactive designers, graphic designers, and developers. However, be aware that most of these articles pertain to the Flash and AIR.
#FLASH ACTIONSCRIPT 3.0 METHODS SOFTWARE#
Actionscript 2 provided the concat(), join(), pop(), push(), reverse(), shift(), slice(), sort(), sortOn(), splice(), and unshift() methods to manipulate arrays. Adobe Flash Creative Suite 4, or CS4, Professional software is the industry-leading authoring environment for creating engaging interactive experiences. Many of the features of ActionScript 3.0, which make it so easy to use, are. So that may be a bit melodramatic, but an application without arrays is like a class without methods (or clouds without water) - they are just that important.
And the Word was grouped with other Words to form arrays. Actionscript 3 Array Methods (from onebyonedesigncom) New Array Methods in Actionscript 3 devon o wolfgang
