I also make a resize to change the size of the image to fit the screen. public static int resize = 1; public static int backgroundWidth = resize * Images.Background.Width; public static int backgroundHeight = resize * Images.Background.Height; Then I take the width and height and move it over to the Game1.cs (The main

问题 I'm trying to create a shallow copy of a struct Board (a chessboard). Before saving a move to the board, I need to check if that move puts the mover in check. To do so, within the Move method (method of a pointer), I dereference the pointer, update and check this possible board for Check. When I change the value of a single value of the Board type (such as possible.headers = "Possible Varient" ) the original b Board is not changed. But here when I call a method updateBoard() it updates both

问题 I want to be able to choose between .mouseover and .click events based on Modernizr's touch/no-touch output. if (Modernizr.touch) { $(el).click(stuff); $(el).click(stuff); } else { $(el).mouseover(stuff); $(el).mouseover(stuff); } But I don't want to write out all that stuff twice. Is it possible to define something so that I can just call: if (Modernizr.touch) {correctEvent = click} else {correctEvent = mouseover} $(el).correctEvent(stuff); $(el).correctEvent(stuff); 回答1: Yes, this is easy

问题 Well, I've started with iPod/iPhone programming using Head First iPhone Development (O'reilly) and I'm typing code out of the book. There are two problems, one is programming related and the other is not. I don't understand the format of objective-c methods. I'm getting an few errors now, based on source code from the book. Which leads me to my next issue. Some of the code is buggy. I think so because I couldn't get the code to run without modifying it. The book has some typos in the text

问题 I read a lot of posts about async methods, but still... I'm a little confused about this. So maybe someone can help me with my case. Right now my code doesn't throw any error, but I know that my code is not good, cause I use async void and I can't wait for all my task to be completed. So, can someone please help me edit this code: In my form class, I create Relation: Relation rel = new Relation(cb_MachineToConnect.Text); In Relation class: public Relation(string machineAddress) { isAsctive =

问题 I am a bit new to Ruby and am writing a program from scratch... I'm getting an error and I can't figure out where it is coming from. I've spent over an hour and i'm sure it's something stupidly simple. I have other similar pages that work fine, but there's some issue with the instance variable. It's almost an identical problem as the link provided. Here's my error: Showing C:/Users/kevin/Desktop/ruby_test/sites/simple_cms/app/views/sections/_form.html.erb where line #4 raised: undefined

问题 I have multiple arrays whose sizes need to be determined by the user input. These arrays should be accessible in the main method as well as the stepTwo() method. However, I am stuck. The user input doesn't come until the main method, but if I declare the arrays in the main method, then I can't access the arrays in the stepTwo() method. I would prefer not to pass the arrays as parameters to stepTwo() as I tried that before but came up with multiple errors. Any suggestions? See below for
