C# Lerping from position to position

阅读更多关于 C# Lerping from position to position

问题 I need to make a picture box to lerp from position to position (like you can do that in unity). How can I do that , is there a built-in function? thanks :) 回答1: Linear interpolation (lerp) is actually a pretty easy function to implement. The equation is float Lerp(float firstFloat, float secondFloat, float by) { return firstFloat * (1 - by) + secondFloat * by; } A higher order Lerp just wraps lower order lerps: Vector2 Lerp(Vector2 firstVector, Vector2 secondVector, float by) { float retX =

问题 here is my next question and i hope some one can help me :-) Is it possible to position a msgbox in wsh/vbs? alt text http://www.4freeimagehost.com/uploads/a9b04cde0527.jpg I need the msgbox everytime in the foreground.

约瑟夫问题约瑟夫问题（有时也称为约瑟夫斯置换，是一个出现在计算机科学和数学中的问题。在计算机编程的算法中，类似问题又称为约瑟夫环。又称“丢手绢问题”. 问题来历据说著名犹太历史学家 Josephus有过以下的故事：在罗马人占领乔塔帕特后，39 个犹太人与Josephus及他的朋友躲到一个洞中，39个犹太人决定宁愿死也不要被敌人抓到，于是决定了一个自杀方式，41个人排成一个圆圈，由第1个人开始报数，每报数到第3人该人就必须自杀，然后再由下一个重新报数，直到所有人都自杀身亡为止。然而Josephus 和他的朋友并不想遵从。首先从一个人开始，越过k-2个人（因为第一个人已经被越过），并杀掉第k个人。接着，再越过k-1个人，并杀掉第k个人。这个过程沿着圆圈一直进行，直到最终只剩下一个人留下，这个人就可以继续活着。问题是，给定了和，一开始要站在什么地方才能避免被处决？Josephus要他的朋友先假装遵从，他将朋友与自己安排在第16个与第31个位置，于是逃过了这场死亡游戏。问题分析：我们使用循环链表来解决问题。定义一个头结点，一个尾节点。然后定义一个被删除的元素的标记del。从第一号开始，隔2号，3号死亡，删除三号，剩余的元素组成一个新的循环链表，3号的下一个4号继续开始循环，跳过5号，6号死亡。一直循环下去，直到剩余俩个人为止（因为剩余俩个人的时候报号没有3了，所以就不会死了）

阅读更多关于 CKEditor 4: How to get and set the cursor / caret position?

问题 I am looking for a way to do 2 very basic things. I just want to retrieve the position of the caret in the text. Then I want to position the caret in a specific position in the text. The purpose is to be able to programmatically modify the text. I have found many people who were trying to do various similar things but not quite what I wanted. In fact, most solutions are looking into the HTML, finding ranges and DOM elements. Maybe that is the way to go but I haven't found a working solution.

CSS基础语法：例如 p{ color:red; background-color: green; } css的四种引入方式: 1 行内式是在标记的style属性中设定CSS样式。这种方式没有体现出CSS的优势，不推荐使用。 <p style="color:red;background-color:green">hello liuliu</p> 2 嵌入式是将CSS样式集中写在网页的<head></head>标签对的<style></style>标签对中。格式如下 <style> p{ color:red; background-color: green; } </style> 3 将一个.css文件引入到HTML文件中 <link rel="stylesheet" href="first.css"> 4 将一个独立的.css文件引入HTML文件中，导入式使用CSS规则引入外部CSS文件，<style>标记也是写在<head>标记中，使用的语法如下： <style> @import 'first.css'; </style> 注意：导入式会在整个网页装载完后再装载CSS文件，因此这就导致了一个问题，如果网页比较大则会儿出现先显示无样式的页面，闪烁一下之后，再出现网页的样式。这是导入式固有的一个缺陷。使用链接式时与导入式不同的是它会以网页文件主体装载前装载CSS文件
