  • How to determine which cells in a grid intersect with a given triangle?

    - by Ray Dey
    I'm currently writing a 2D AI simulation, but I'm not completely certain how to check whether the position of an agent is within the field of view of another. Currently, my world partitioning is simple cell-space partitioning (a grid). I want to use a triangle to represent the field of view, but how can I calculate the cells that intersect with the triangle? Similar to this picture: The red areas are the cells I want to calculate, by checking whether the triangle intersects those cells. Thanks in advance. EDIT: Just to add to the confusion (or perhaps even make it easier). Each cell has a min and max vector where the min is the bottom left corner and the max is the top right corner.

  • Mallocing an unsigned char array to store ints

    - by Max Desmond
    I keep getting a segmentation fault when i test the following code. I am currently unable to find an answer after having searched the web. a = (byte *)malloc(sizeof(byte) * x ) ; for( i = 0 ; i < x-1 ; i++ ) { scanf("%d", &y ) ; a[i] = y ; } Both y and x are initialized. X is the size of the array determined by the user. The segmentation fault is on the second to last integer to be added, i found this by adding printf("roar") ; before setting a[i] to y and entering one number at a time. Byte is a typedef of an unsigned char. Note: I've also tried using a[i] = (byte)y ; A is ininitalized as follows byte *a ; If you need to view the entire code it is this: #include <stdio.h> #include <stdlib.h> #include "sort.h" int p_cmp_f () ; int main( int argc, char *argv[] ) { int x, y, i, choice ; byte *a ; while( choice !=2 ) { printf( "Would you like to sort integers?\n1. Yes\n2. No\n" ) ; scanf("%d", &choice ) ; switch(choice) { case 1: printf( "Enter the length of the array: " ) ; scanf( "%d", &x ) ; a = (byte *)malloc(sizeof( byte ) * x ) ; printf( "Enter %d integers to add to the array: ", x ) ; for( i = 0 ; i < x -1 ; i++ ) { scanf( "%d", &y ) ; a[i] = y ; } switch( choice ) { case 1: bubble_sort( a, x, sizeof(int), p_cmp_f ) ; for( i = 0 ; i < x ; i++ ) printf( "%d", a[i] ; break ; case 2: selection_sort( a, x, sizeof(int), p_cmp_f ) ; for( i = 0 ; i < x; i++ ) printf( "%d", a[i] ; break ; case 3: insertion_sort( a, x, sizeof(int), p_cmp_f ) ; for( i = 0 ; i < x ; i++ ) printf( "%d", a[i] ; break ; case 4: merge_sort( a, x, sizeof(int), p_cmp_f ) ; for( i = 0 ; i < x ; i++ ) printf( "%d", a[i] ; break ; case 5: quick_sort( a, x, sizeof(int), p_cmp_f ) ; for( i = 0 ; i < x ; i++ ) printf( "%d", a[i] ; break ; default: printf("Enter either 1,2,3,4, or 5" ) ; break ; } case 2: printf( "Thank you for using this program\n" ) ; return 0 ; break ; default: printf( "Enter either 1 or 2: " ) ; break ; } } free(a) ; return 0 ; } int p_cmp_f( byte *element1, byte *element2 ) { return *((int *)element1) - *((int *)element2) ; }

  • Set text equal to string and pass to receipt printer at a different size on iOS

    - by Max Roper
    I am using the StarIO SDK to print text to a receipt printer and I am trying to get a certain line of text larger than the rest. I have some help from their support but I can't really get it to go. -(void)print{ NSMutableString *final=[NSMutableString stringWithFormat:@"-----"]; [final appendFormat:@"\n\nLevel:%@ Section:%@ Row:%@ Seat:%@", [response_dict objectForKey:@"level"], [response_dict objectForKey:@"section"],[response_dict objectForKey:@"row"],[response_dict objectForKey:@"seat"]]; There is a bunch of other stuff that is printing, but that is the line that I would like to be a different size than the rest. The StarIO support said that I should try and pass that to this... -(IBAction)PrintText { NSString *portName = [IOS_SDKViewController getPortName]; NSString *portSettings = [IOS_SDKViewController getPortSettings]; [PrinterFunctions PrintTextWithPortname:portName portSettings:portSettings heightExpansion:heightExpansion widthExpansion:widthExpansion textData:textData textDataSize:[textNSData length]]; free(textData); } Would love some help if possible. :) Thanks so much. This is the main bit I think I would need from the StarIO Text formatting doc... - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { array_hieghtExpansion = [[NSMutableArray alloc] init]; [array_hieghtExpansion addObject:@"1"]; [array_hieghtExpansion addObject:@"2"]; [array_hieghtExpansion addObject:@"3"]; [array_hieghtExpansion addObject:@"4"]; [array_hieghtExpansion addObject:@"5"]; [array_hieghtExpansion addObject:@"6"]; array_widthExpansion = [[NSMutableArray alloc] init]; [array_widthExpansion addObject:@"1"]; [array_widthExpansion addObject:@"2"]; [array_widthExpansion addObject:@"3"]; [array_widthExpansion addObject:@"4"]; [array_widthExpansion addObject:@"5"]; [array_widthExpansion addObject:@"6"]; array_alignment = [[NSMutableArray alloc] init]; [array_alignment addObject:@"Left"]; [array_alignment addObject:@"Center"]; [array_alignment addObject:@"Right"]; } return self; } and int heightExpansion = [pickerpopup_heightExpansion getSelectedIndex]; int widthExpansion = [pickerpopup_widthExpansion getSelectedIndex];

  • Trouble assigning a tr1::shared_ptr

    - by Max
    I've got a class that has a tr1::shared_ptr as a member, like so: class Foo { std::tr1::shared_ptr<TCODBsp> bsp; void Bar(); } In member function Bar, I try to assign it like this: bsp = newTCODBsp(x,y,w,h); g++ then gives me this error no match for ‘operator=’ in ‘((yarl::mapGen::MapGenerator*)this)->yarl::mapGen::MapGenerator::bsp = (operator new(40u), (<statement>, ((TCODBsp*)<anonymous>)))’ /usr/include/c++/4.4/tr1/shared_ptr.h:834: note: candidates are: std::tr1::shared_ptr<TCODBsp>& std::tr1::shared_ptr<TCODBsp>::operator=(const std::tr1::shared_ptr<TCODBsp>&) in my code, Foo is actually yarl::mapGen::MapGenerator. What am I doing wrong?

  • Create unique identifier for different row-groups

    - by Max van der Heijden
    I want to number certain combinations of row in a dataframe (which is ordered on ID and on Time) tc <- textConnection(' id time end_yn number abc 10 0 1 abc 11 0 2 abc 12 1 3 abc 13 0 1 def 10 0 1 def 15 1 2 def 16 0 1 def 17 0 2 def 18 1 3 ') test <- read.table(tc, header=TRUE) The goal is to create a new column ("journey_nr") that give a unique number to each row based on the journey it belongs to. Journeys are defined as a sequence of rows per id up until to end_yn == 1, also if end_ynnever becomes 1, the journey should also be numbered (see the expected outcome example). It is only possible to have end_yn == 0 journeys at the end of a collection of rows for an ID (as shown at row 4 for id 3). So either no end_yn == 1 has occured for that ID or that happened before the end_yn == 0-journey (see id == abc in the example). I know how to number using the data.table package, but I do not know which columns to combine in order to get the expected outcome. I've searched the data.table-tag on SO, but could not find a similar problem. Expected outcome: id time end_yn number journey abc 10 0 1 1 abc 11 0 2 1 abc 12 1 3 1 abc 13 0 1 2 def 10 0 1 3 def 15 1 2 3 def 16 0 1 4 def 17 0 2 4 def 18 1 3 4

    - by Max Gontar
    Hi! There is an email service ExactTarget with web service API. There are samples (in php though) for sending email to whole list instantly, or to single subscriber by triggered action. It's pretty hard to get in it's documentation, and I couldn't find explanation how to send email to a single subscriber instantly without having some triggering actions. Any help or advice will be great. Thanks.

  • undefined reference to static member variable

    - by Max
    Hi. I have this class that has a static member. it is also a base class for several other classes in my program. Here's its header file: #ifndef YARL_OBJECT_HPP #define YARL_OBJECT_HPP namespace yarlObject { class YarlObject { // Member Variables private: static int nextID; // keeps track of the next ID number to be used int ID; // the identifier for a specific object // Member Functions public: YarlObject(): ID(++nextID) {} virtual ~YarlObject() {} int getID() const {return ID;} }; } #endif and here's its implementation file. #include "YarlObject.hpp" namespace yarlObject { int YarlObject::nextID = 0; } I'm using g++, and it returns three undefined reference to 'yarlObject::YarlObject::nextID linker errors. If I change the ++nextID phrase in the constructor to just nextID, then I only get one error, and if I change it to 1, then it links correctly. I imagine it's something simple, but what's going on?

  • Spring 3 - Theme with separate JSP

    - by Max
    Hi, I'm trying to rewrite some Spring 1.2 code to Spring 3.0 one. Currently I'm stuck with JSP resolved by URL problem. Application uses separate JSP files with different layouts for serving the same model from the same controller. The JSP is switched using interceptor, that intercepts the url and changes the view. For example: /design_one/mypage.htm -> MyPageController -> /design_one/mypage.jsp /design_two/mypage.htm -> MyPageController -> /design_two/mypage.jsp Is there a way to make same or similar functionality using something better than raw interceptors?

  • MS Exam 70-536 - How to throw and handle exception from thread?

    - by Max Gontar
    Hello! In MS Exam 70-536 .Net Foundation, Chapter 7 "Threading" in Lesson 1 Creating Threads there is a text: Be aware that because the WorkWithParameter method takes an object, Thread.Start could be called with any object instead of the string it expects. Being careful in choosing your starting method for a thread to deal with unknown types is crucial to good threading code. Instead of blindly casting the method parameter into our string, it is a better practice to test the type of the object, as shown in the following example: ' VB Dim info As String = o as String If info Is Nothing Then Throw InvalidProgramException("Parameter for thread must be a string") End If // C# string info = o as string; if (info == null) { throw InvalidProgramException("Parameter for thread must be a string"); } So, I've tried this but exception is not handled properly (no console exception entry, program is terminated), what is wrong with my code (below)? class Program { static void Main(string[] args) { Thread thread = new Thread(SomeWork); try { thread.Start(null); thread.Join(); } catch (InvalidProgramException ex) { Console.WriteLine(ex.Message); } finally { Console.ReadKey(); } } private static void SomeWork(Object o) { String value = (String)o; if (value == null) { throw new InvalidProgramException("Parameter for "+ "thread must be a string"); } } } Thanks for your time!

  • Port a Rails App from Windows to Mac or Linux

    Hello I've been a Rails developer on Windows for quite some time now, but I recently completed my biggest project yet (it's quite extensive, took me over a year to build) but I am having trouble deploying it. The combination of it's size, complexity and a windows environment is making it needlessly complex to deploy. I am thinking about getting an old mac mini and using it just for rails development. Either that or install unix on another box. Is there any way I can port my app to this mac or linux machine, without having to start over? I can't find any resources on the internets about this.

  • JList with JScrollPane and prototype cell value wraps element names (replaces with dots instead of s

    - by Tom
    I've got a Jlist inside a JScrollPane and I've set a prototype value so that it doesn't have to calculate the width for big lists, but just uses this default width. Now, the problem is that the Jlist is for some reason replacing the end of an element with dots (...) so that a horizontal scrollbar will never be shown. How do I disable with "wrapping"? So that long elements are not being replaced with dots if they are wider than the Jlist's width? I've reproduced the issue in a small example application. Please run it if you don't understand what I mean: import javax.swing.*; import java.awt.*; public class Test { //window private static final int windowWidth = 450; private static final int windowHeight = 500; //components private JFrame frame; private JList classesList; private DefaultListModel classesListModel; public Test() { load(); } private void load() { //create window frame = new JFrame("Test"); frame.setSize(windowWidth, windowHeight); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setUndecorated(true); frame.getRootPane().setWindowDecorationStyle(JRootPane.PLAIN_DIALOG); //classes list classesListModel = new DefaultListModel(); classesList = new JList(classesListModel); classesList.setPrototypeCellValue("prototype value"); classesList.setSelectionMode(ListSelectionModel.SINGLE_SELECTION); classesList.setVisibleRowCount(20); JScrollPane scrollClasses = new JScrollPane(classesList, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED, JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED); for (int i = 0; i < 200; i++) { classesListModel.addElement("this is a long string, does not fit in width"); } //panel JPanel drawingArea = new JPanel(); drawingArea.setBackground(Color.white); drawingArea.add(scrollClasses); frame.add(drawingArea); //set visible frame.setVisible(true); } } Even if you force horizontal scrollbar, you still won't be able to scroll because the element is actually not wider than the width because of the dot (...) wrapping. Thanks in advance.

  • How do I change text color on the selected row inside a ListView/GridView? (using Expression Dark th

    - by Thiado de Arruda
    I'm using theExpression Dark WPF Theme(http://wpfthemes.codeplex.com/) with a ListView(view property set to a GridView) to display some user data like the following : <ListView Grid.Row="1" ItemsSource="{Binding RegisteredUsers}" SelectedItem="{Binding SelectedUser}" > <ListView.View> <GridView> <GridViewColumn Header="Login" DisplayMemberBinding="{Binding Login}" Width="60"/> <GridViewColumn Header="Full Name" DisplayMemberBinding="{Binding FullName}" Width="180"/> <GridViewColumn Header="Last logon" DisplayMemberBinding="{Binding LastLogon}" Width="120"/> <GridViewColumn Header="Photo" Width="50"> <GridViewColumn.CellTemplate> <DataTemplate> <Image Source="{Binding Photo}" Width="30" Height="35"/> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView> </ListView.View> </ListView> The rows have white text with a dark background and white background when selected, however the text color doesnt change when selected and it makes very difficult to read, I would like the text to have a dark color when the row is selected. I have searched for a way to style the text color but with no success, here is the control template for the ListViewItem : <Border SnapsToDevicePixels="true" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="2" x:Name="border"> <Grid Margin="2,0,2,0"> <Rectangle x:Name="Background" IsHitTestVisible="False" Opacity="0.25" Fill="{StaticResource NormalBrush}" RadiusX="1" RadiusY="1"/> <Rectangle x:Name="HoverRectangle" IsHitTestVisible="False" Opacity="0" Fill="{StaticResource NormalBrush}" RadiusX="1" RadiusY="1"/> <Rectangle x:Name="SelectedRectangle" IsHitTestVisible="False" Opacity="0" Fill="{StaticResource SelectedBackgroundBrush}" RadiusX="1" RadiusY="1"/> <GridViewRowPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" Margin="0,2,0,2" VerticalAlignment="Stretch" /> </Grid> </Border> The trigger that changes the background color simply applies an animation to change the 'SelectedRectangle' opacity, but I cant change the text color on the same trigger(I tried using a setter for the foreground color on the ListViewItem, but with no success). Does someone have a clue on that?

  • Managed HttpListener vs C++ Network Lib - Requires admin rights?

    - by Max
    So, I have noticed that starting an HttpListener is considered impolite according to Win 7. I cannot do so without administrative rights without adding myself to some URL reservation list. In theory, this is alright, but I'd like to make my program as little invasive as possible. My main other alternative is something like the c++ Network Library, which utilizes boost. This is probably not as simple as a HttpListener though. Will this circumvent the admin rights requirement for listening to some HTTP url? How does windows handle http listening? Right now I'm just listening to http://+:xxxx/url, I guess it's fully possible to just create a Socket listening at port xxxx and provide my own/third party http implementation?
