Uniform

Swift 中的枚举类型可以辅助实现特定的类或者结构体的功能。swift支持类型嵌套，把需要嵌套的类型的定义写在被嵌套的类型的{ } 中。 考虑下面的情景，某市的中学生需要定制校服，根据学生的年纪和款式定制不同的校服，所以在定制校服计划时就要考虑所有的年级和款式，年级和款式有多个值，这里就形成了一个类型的嵌套。可以使用枚举类型，先来定义一个嵌套有枚举的结构体： struct SchoolUniform { enum Style:String { case Sports = “运动服”,Suit = “中山装” } enum Grade:String { case One = “初一”，Two = “初二” , Three = “初三” } let myStyle:Style let myGrade:Grade func customize() { print(“我的年级\(myGrade.rawValue) 我的款式\(myStyle.rawValue)”) } } let uniform4XiaoMing = SchoolUniform(myStyle: .Suit, myGrade: .One) //使用默认构造器。 uniform4XiaoMing.customize() //会输出“我的年级初一我的款式中山装” 每个学生的条件只能符合枚举中的其中一项

I'm using jquery uniform on one of the project I'm working on. Since this is admin panel, I truly don't have option to show. I will explain my problem What I'm trying to do is quite simple. I'm adding some form elements (like select, check box, text input) to the page with ajax. Every single thing works except re-styling those dynamically added form elements. function step2 () { $.post( siteUrl + "includes/ajax/members/add-subscription.php?do=step2", $("#selectedSubscribers").serialize(), function( data ) { $('.step2_content').html(data); $.uniform.update(); }); } Anyone experienced similar

How fast is glUseProgram()? Is there anything better (faster)?: Here are my thoughts: Use 1 universal shader program, but with many input settings and attributes (settings for each graphics class) Use more than 1 shader for each graphics class What state are uniforms in after changing the shader program? Do they save values (for example, values of matrices)? Here are what I consider the benefits of #1 to be: Doesn't use glUseProgram() And the benefits of #2: No matrix changes (for example, if class Menu and class Scene3D have different Projection matrices) What of the two options is better

I have a simple translation animation in an Android game I am developing. When I test it on several devices, it runs at very different speeds on 10-inch tablets, 7-inch tablets and smartphones. What is the "state of the art" way of getting a uniform animation speed on different devices? Thanks, I finally decided to use display.metrics to get the pixel density of the devices. Then I adjust the translation motion speed by dividing by the density value. Still wondering if this is the "state of the art" way of controlling animation speed on various devices??? Animation duration should be same on

If we have a Map<T, Integer> , let's say the Integer value represents "how many" Ts there are. Thus, I want to uniformly select a T based on its Integer value. If the map contains Strings with "a"=4 and "b"=6, then I want it so that 40% of the time "a" is selected and 60% of the time "b" is selected. Most importantly, I'd like this in O(n), n being two (not ten) in my previous example. I originally made an ArrayList containing the keys by how many values it had (and simply returning any random index), but this process is not only very slow, but completely counterintuitive for what the Map<T,
