In a tile based game, how could a tile identified as just a "road tile" in an array determine what kind of road tile it should be (horizontal road, vertical road, left turn, etc)? So, the array that describes the map would be like this: There are generic grass tiles and generic road tiles. However, when the map is actually rendered f...
Does the byte[] array size reflects the same size of bytes to be transmitted if I need to transmit the file via a webservice? E.G: byte[] testarray = new byte[100000] means that its size if transmitted will be approx 100,000 bytes (100kB)? thanks ...
Hello! I am using Codeigniter to pass an array of data from a controller into a model for insertion into the database. The code in the controller looks like this: $result = $this->items_model->add( array( 'ite_owner' => $this->post('user'), 'ite_type' => $this->post('type'), 'ite_value_1' => $this->post('va...

NSArray chemConstantArray = [[NSArray alloc] initWithObjects:0.0021400, 0.0012840, 0.0010700, nil]; Gives me four errors: Incompatible type for argument 1 of 'initWithObjects:' Invalid initializer Statically allocated instance of Objective-C class 'NSArray' x 2 Which makes sense, as floats are not objects, but how can I make an arr...
Hi I have an array filled with instances of a custom class which contains two String properties, firstname and lastname. Both have a getter method which is equal to the name of the property itself. There is also a method for retrieving the Full name of a person called "getFullName". Consider the example below. CustomClass *person = [[...
I'm struggling with this, I am still new to javascript and am trying the jquery $.inarray function as I need to be able to find a value in an array so that I can return other values from the same array "line", such as its ID. When I try to use jquery's inarray function, like this, I just get back -1, saying that it doesn't exist when I...
OK let's say I want to take this piece of text: text ex 1. 6, 6, 6, 6, 6, 6, 6, 6, 95, 95, 95, 51, 6, 60, 60, 60, 60, 60, 60, 6, 95, 95, 95, 51, 6, 60, 35, 35, 35, 35, 60, 6, 6, 6, 95, 95, 6, 60, 35, 35, 35, 35, 60, 60, 6, 6, 6, 6, 6, 60, 35, 35, 35, 35, 35, 60...
Basically the title says it all. Why does using a primitive data type work in the second "for-each" loop when I am looping over an array of objects. Is there a casting back to the primitive equivalent of the Integer object occurring behind the scenes? import java.util.Arrays; import java.util.Collections; public class CodeTestingClas...
Let's say I have a function like this (it's only an example, so do not offer me better ways to create 0,1,2,... style array): def createArray(size: Int): Array[Int] = { for (i <- 0 until size) yield i } But the compiler get upset with some mysterious type mismatch error: (fragment of compare-images.scala):39: error: type mismatch; ...
Question very simple - say, i got function, which receives array as its arguments void calc(double[] data) how do "split" this data in two subarrays and pass to sub functions like this calc_sub(data(0, length/2)); cals_sub(data(length /2, length /2)); i hope, you got the idea - in c++ i would write this void calc(double * data, in...
Hello, I am loading an image using the OpenEXR library. This works fine, except the image is loaded rotated 180 degrees. I use the loop shown below to reverse the array but sometimes the program will quit and xcode will give me an EXEC_BAD_ACCESS error (Which I assume is the same as an access violation in msvc). It does not happen every...

Hi everybody, I´m fetching my database for images to create a gallery. Every row appear inside a <li>. My question is, is it possible, that the first <li> have a class (for example, "visible"), and all the other <li> have a class named "hidden". So the first $row would have a different class than the following... Hope I made myself clear...
Given an Array Literal inside a JavaScript Object, accessing its own object's properties does not seem to work: var closure = { myPic : document.getElementById('pic1'), picArray: [this.myPic] } alert(closure.picArray[0]); // alerts [undefined] Whereas declaring an Array Item by accessing an other JavaScrip...
I have an array with a series of event IDs organized like this: $event['year']['month']['day'] = $event_id (full structure below). Basically, I want to output the next 5 events (or so) from a given date (such as today). I've gone through the PHP manual, but haven't found a suitable solution. I suppose I could just iterate through each ...
I think this is a general Java question, but it does involve some Android stuff. So here's the deal: I've got a JNI wrapped version of MPG123 for Android, and I can pull PCM data from an MP3 file on the SDCard. I'd like to pull a chunk this data, do an analysis on it using another class I wrote, then push it into a queue. Ideally, I'd...
I want to add multiple BigInteger values to an ArrayList. All I have found is examples that repeatedly add single values, each expressed on their own line of code. I'm looking for something like ArrayList<BigInteger> array = {bigInt1, bigInt2, bigInt3}; and instead it's: ArrayList<BigInteger> array = new ArrayList<BigInteger>(); arra...
I am trying to accept input of two integers, separated by a space: 3 5 and save that into an integer array. I do this 3 times, but I am having trouble converting this from string to integers. Here is my loop: for i in 1..3 puts "What is point " + i.to_s + " ?" # asks for input s.push gets.split(" ") end Then, I want to have...
