One: iOS sandbox knowledgeFor security reasons, the iOS system puts each application and data into a sandbox, and the app can access only the files in its sandbox directory, network resources, etc. (with exceptions such as system contacts, cameras,
Arctangent) As you may have guessed, it is simply the inverse function of the tangent function. We only need to input the opposite side and the adjacent side.To obtain the corresponding angle. There are two functions in flash that can calculate
Display list
It can be said that Starling followed the same rules as the native Flash display list. The display object in the Starling will not
Access its stage property until it is added to the display list. In previous programming, we have been
Random
Afternoon nothing to do, got a random cut jigsaw effect, not to make judgments, just a cutting method of calculation, later finishing should be a finished product, hehe ~ principle is to use bitmap to cut the map, used to do too much to cover
The elastic motion in the animation is similar to the Single Pendulum Motion or the spring (Hu Ke's law F = kx) vibration in the classical physical mechanics.
Let's take a look at the following simulated Demonstration:
Rule:The ball first
The effect of the three-day music spectrum:
Includes five classes:
MusicControl class, which is used to control music, including the control of music loading and playback.
ID3Control class, used to extract information related to music files,
It is much smaller than the system's built-in components, and supports progress bar display (it is useful to show the buffer progress when making a player). It also supports triangle volume adjustment display.
Example:
Package {import flash.
The last part mentioned the basic concepts such as node, cost, and valuation formula. With this knowledge, we can start our journey!
For example, this is a grid with five rows and eight columns. The yellow node is the start point, the red node is
Just wrote a part

Collision detection can be divided into two categories: Collision Detection of objects and objects, and Collision Detection of objects and points.
To facilitate the test, first write a box class (generate a small rectangle)
Package {import flash.
In as3, only vector graphs support 9-grid scaling, and bitmap setting scale9grid does not work;
Solution: 1. Split the bitmap into a vector image, cut it into 9 points, and merge it;Bitmapslice9.zip.

The Code posted here is intended for those who need it, rather than providing the source code for others. Therefore, we apologize. This algorithm does not use a hash table as a storage container with the traditional 2D array. The advantage of this
Recently in a three-dimensional topology of the power system, using LineSegment to draw the connection between the device cable. In order to make the picture more vivid, it is necessary to add particle moving effect on the line to simulate the flow
If you do not consider the security factor (anyone can connect FluorineFx for video recording without logon authentication), the server does not need to write a line of code, you only need to create a subdirectory under the apps directory as an

Because the project needs to use Flash to develop 3D animation, it reminds me of the several popular Flash 3D libraries that I never knew where to find PV3D and Away3D, it is said that PV3D has high performance but is not flexible. Away3D is
