facets, as a visual designer, has been trying to integrate visual design and user experience closely. Choose some of the recent cases you have done to share and discuss with you. I hope you will give us valuable advice. Based on the above user analysis and existing materials, start creative analysis.

can destroy the enemy spaceships as stored as possible. To simplify the problem, the beam cannon can shot at any area in the space, and the attack area is rectangular. the rectangle parallels to the coordinate axes and cannot rotate. it can only move horizontally or vertically. the enemy spaceship in the space can be considered as a point projected to the attack plane. if the point is in the Rectangular Attack Area of the beam cannon (including bord

the class, the code will be further simplified. interface IRenderable{ function render();} class RenderProcess implements IProcess{ private var targets:Vector. Then some code of our spaceship class will become like this: class Spaceship implements IRenderable{ public var view:DisplayObject; public var position:Point; public var rotation:Number; public function render():void { view.x = position.x;

Test instructions: Because of the insane destruction of nature, people realize that after about 2,300 years, the earth can no longer live, and then set up new green space on the moon so as to emigrate when needed. Surprisingly, the 2177 winter due to unknown reasons, the Earth's environment has been a chain collapse, the human must in the shortest possible time to move inland to the moon.The existing n space stations are between the Earth and the Moon (ref. 1). n), M public transport spacecraft

daily use, we added the syntax sugar of the null merge operator (??). If a variable exists and the value is not NULL, it returns its own value, otherwise it returns its second operand. Spaceship operator (combination comparator) (PHP 7) The spaceship operator is used to compare two expressions. When $ A is less than, equal to, or greater than $b, it returns-1, 0, or 1, respectively. The principle of compa

the type of the function return value. The available types are the same as the types available in the parameter declaration. The above routines will output: Array([0] = 6[1] = 15[2] = 24) Null merge operator (PHP 7) Because of the large number of simultaneous use of ternary expressions and isset () in daily use, we added the syntax sugar of the null merge operator (??). If a variable exists and the value is not NULL, it returns its own value, otherwise it returns its second operand.

Pid = 1, 5091 Problem DescriptionRecently, the gamma galaxies broke out Star Wars. each planet is warring for resources. in the Star Wars, Planet X is under attack by other planets. now, a large wave of enemy spaceships is approaching. there is a very large Beam Cannon on the Planet X, and it is very powerful, which can destroy all the spaceships in its attack rang

; Using PHP 7 We can use: Use Framework\module\{foo, Bar, Baz}; Or, if you are more inclined to multi-line style: Use framework\module{ Foo, Bar, Baz}; Null merge operator This solves a common problem in PHP programming, when we want to assign the value of a variable to another variable, if the latter actually has a setting, it provides a different value for it. Typically used when we process user-supplied input. Before PHP 7: if (Isset ($foo)) { $bar = $foo

, data communication, so this road is also a white dashed line, you see that word outlet outlet is an expression used to represent a controller's attribute to the view communication, so we're going to create a outlets to view in the controller, what about the model and view? The purpose of this course is that they will never communicate with each other. I'm sure you all understand why the model doesn't communicate with view, because model and user interface are irrelevant, you can have a model o

the results of the data dispersion are less than the cache hit ratio. There is also a problem, if the single-core situation, once the task is more, it processing speed will be more and more slow.Entity Component System, we separate the data and functions, render contains the data, by classifying the data, and then sent to different tasks for processing. As shown below, this is a combined architecture diagram.Consider a practical example of how much performance it has improved. As shown, the tra

1. Scalar type declarationThere are two modes: mandatory (default) and strict mode. You can now use the following type parameters, whether in forced or strict mode: string (String), Integer (int), floating-point number (float), and Boolean (bool).2. return value type declarationThe return type declaration indicates the type of the function return value. The available types are the same as the types available in the parameter declaration.PHP function arrayssum (array []):array{returnarray_map( f

of the response, the key is , we can get the response data from the ResponseText property of the Xhr object, then stitch the template and render the DOM. But in the IMG, IFRAME, script these tags, we are deprived of control, we set the SRC attribute, the browser is responsible for sending requests, the server returns the response is directly loaded back to the DOM, we do not interfere with the opportunity to modify the data. What about ? It's like launching a

The famous Schwartzian conversion in Perl, whose background mainly involves sorting problems: For example, sort alphabetically by file name, with the following code: Copy CodeThe code is as follows: Use strict; Use warnings; My @files = Glob "*.xml"; #perl中文件操作符glob提供相当于shell中的通配符的功能 My @sorted_files = sort @files; #sort (), sorted by default alphabetical order For example, depending on the length of the file name, the code is as follows: Copy CodeThe code is as follows: Use strict; Use
