comet moving through an elliptical trajectory. 4. After winning the prize, an animation is displayed. After reading the functional requirements, let's see how to write the code: First look at the simple initialization code: Bool LotteryTurnTest: init () {if (! Layer: init () {return false;} auto bgSize = Director: getInstance ()-> getWinSize (); m_pBg = Sprite: create (LotteryTurn/bg_big.png ); m_pBg-> setPosition (Vec2 (bgSize. width/2, bgSize. hei

This article belongs to the HTML5 canvas painting series tutorial In the canvas, you can easily draw a circle using the arc method. Originally, the circle can be regarded as an elliptic with equal width and height, but there is no elliptical method in the canvas, we need to simulate it using other methods. First, we need to specify the parameters required to draw an elliptic. The basic geometric knowledge tells us that the elliptic requires the co

:.The above formula can be expressed as an implicit equation:Due to the symmetry of the elliptic, only the elliptical arc in the First quadrant can be considered. The formula for calculating the normal vectors of an elliptical arc is as follows:A point with a slope of-1 on an elliptical arc is divided into the upper and lower parts, as shown in Figure 2.3. In the

, a pointer, can be a turntable or a pointer, this article is a turntable. 2. When the turntable is turned, the speed is fast, slow, and then stopped. 3. When the turntable is being turned, various particle effects are animated, including the ring-like flashing stars and small comet moving through an elliptical trajectory. 4. After winning the prize, an animation is displayed. After reading the functional requirements, let's see how to write the code

I recently compiled the source code of the Android operating system based on the information I saw. The result is successful, but the process is tortuous. The first thing I want to talk about is the prerequisites. This is very important, at first, I took a lot of detours because I didn't meet the prerequisites.1, get the latest Android source code from the http://source.android.com compilation information, this is not the following compilation must be used,However, it is indeed more accurate in

Sometimes the code is too long to look at, especially when reading the source code, you need to fold the code that you don't care about first to look at the code that you are most concerned about. Vim comes with the code folding function.Foldmethod can be configured to define the folding mode. There are 6 optional methods: 1. Manual // manually define the folding mode. 2. indent // fold with indentation 3.
