• 3D Mesh Collision Help

  - by BlackAfricano

  I am new to XNA (I have only been working in it for a countable number of weeks) as well as to these forums (I have only made 1-2 other posts), so this may seem like a strange request, but I am wondering if anybody knows about more advanced collision in XNA. So far I have only been able to figure out BoundingSphere's which seem to be the simplest of the methods, and I was thinking of looking more into BoundingBoxes because the game I have is a 2-3D platformer. The problem I realized was that if I wanted to get any more advanced than stages in the shape of a box, I would face some immediate dilemmas. I was hoping somebody here was knowledgeable on the subject and could inform me where I could get started learning how to do something like this: https://www.youtube.com/watch?v=ekMD_Gtt8d4 Although the game in this video isn't very pretty, the mesh collision looks like what I'm looking for. I am hoping for the most complete solution, if possible.

• Interface hierarchy design for separate domains

  - by jerzi

  There are businesses and people. People could be liked and businesses could be commented on: class Like class Comment class Person implements iLikeTarget class Business implements iCommentTarget Likes and comments are performed by a user(person) so they are authored: class Like implements iAuthored class Comment implements iAuthored People's like could also be used in their history: class history class Like implements iAuthored, iHistoryTarget Now, a smart developer comes and says each history is attached to a user so history should be authored: interface iHistoryTarget extends iAuthored so it could be removed from class Like: class Person implements iLikeTarget class Business implements iCommentTarget class Like implements iHistoryTarget class Comment implements iAuthored class history interface iHistoryTarget extends iAuthored Here, another smart guy comes with a question: How could I capture the Authored fact in Like and Comment classes? He may knows nothing about history concept in the project. By scalling these kind of functionallities, interfaces may goes to their encapsulated types which cause more type strength, on the other hand explicitness suffered and also code end users will face much pain to process. So here is the question: Should I encapsulate those dependant types to their parent types (interface hierarchies) or not or explicitly repeat each type for every single level of my type system or ...?

• Sudden Breakthroughs (Miracles at work)

  - by MobileDev123

  Lot of things has been discussed that can be taken as negative things about programmers work. Lets discuss about something good and unexpected things that happen to programmers. Example: (After R&D of two days and a lot of disappointments) You just spend an hour with your PM to explain that some feature due to some problem you are unable to release this module in today's beta... after a lot of arguments you are given an hour to make your app work without this module. You sit on your workstation to make a release and all of a sudden you find what turns out to be a silly little problem.... (you solve it and prepare a desired build) did you face miracle (= sudden, positive surprises?) in your life?? what was your reaction in case you have come through such experience?? (N.B. I know my English is not that good and that's why I'm open to every linguistic mistakes needed to be corrected)

• How can I build this payment receipt/booking application?

  - by Festus

  I'm planning to build a payment receipt/booking application for a media company with several branches in different locations. The application should be able to move data across the network/internet to a central database where the administrator/accountant in a different location will be able to see the result of the entire job for the day from each branch. Application will run on windows environment. Will be able to send result of the booking to a Point Of Sales printer for print output. Now, I'm confused about choosing the right programming language to accomplish this task. I'm between beginner/intermediate level in PHP, I know HTML/CSS and JavaScript. I have tried to do this in PHP but, I'm face with several challenges and I fear for the POS part since PHP application run on the web browser. I don't know if python will be best suited for this and how long will it take someone with my experience level to pick up python. Any suggestion will be highly appreciated.

  Au diable l'interview Technique d'avant embauche en entreprise Un développeur estime que cette pratique est ridicule et sa réussite tient plus de la chanceQuel programmeur ne se souvient pas de ses premiers entretiens d'embauche en entreprise ?

• Intersection of player and mesh

  - by Will

  I have a 3D scene, and a player that can move about in it. In a time-step the player can move from point A to point B. The player should follow the terrain height but slow going up cliffs and then fall back, or stop when jumping and hitting a wall and so on. In my first prototype I determine the Y at the player's centre's X,Z by intersecting a ray with every triangle in the scene. I am not checking their path, but rather just sampling their end-point for each tick. Despite this being Javascript, it works acceptably performance-wise. However, because I am modeling the player as a single point, the player can position themselves so that they are half-in a cliff face and so on. I need to model them as as a solid e.g. some cluster of spheres or a even their fuller mesh. I am also concerned that if they were moving faster they might miss the test altogether. How should I solve this?

• How can I calculate the angle between two 2D vectors?

  - by Error 454

  I am working on some movement AI where there are no obstacles and movement is restricted to the XY plane. I am calculating two vectors, v, the facing direction of ship 1, and w, the vector pointing from the position of ship 1 to ship 2. I am then calculating the angle between these two vectors using the formula arccos((v · w) / (|v| · |w|)) The problem I'm having is that arccos only returns values between 0° and 180°. This makes it impossible to determine whether I should turn left or right to face the other ship. Is there a better way to do this?

• Impact of migrating home page from HTTP to HTTPS on search results

  - by 2Stroke SEO

  I've had to change one of my site's home page to HTTPS from HTTP. I had plenty of links coming into the HTTP page and was performing well in Google against many of my targeted search phrases. I did a 301 redirect from the HTTP page to transfer the link juice to the HTTPS page (and to prevent duplicate content issues) but my search rankings have tanked which indicates no link juice has been transferred. My PageRank has vanished - which I'd expect - but I'm really surprised that the SERP rankings fell off the face of the earth. Anyone have any ideas how I can recover from this? I've waited a couple of months since the changes took effect just in case Google was taking time to check it out.

• Is it legal to develop a game usung some version of D&D, something similar to Baldurs Gate?

  - by Max

  For a while now I've been thinking about trying my hand at creating a game similar in spirit and execution to Baldurs Gate, Icewind Dale and offshoots. I'd rather not face the full bulk of work in implementing my own RPG system - I'd like to use D&D rules. Now, reading about the subject it seems there is something called "The License" which allows a company to brand a game as D&D. This license seems to be exclusive, and let's just say I don't have the money to buy it :p. Is it still legal for me to implement and release such a game? Commercially or open-source? I'm not sure exactly which edition would fit the best, but since Baldurs Gate is based of 2nd edition, could I go ahead an implement that? in short: what are the issues concerning licensing and publishing when it comes to D&D? Also: Didn't see any similar question...

• Someone who needs inspiration [on hold]

  - by Anestis

  My apologies if it is not a code problem. However, it is a problem that concerns programming. As a recently graduated Computer Systems Engineering I have gained some basic knowledge with programming using JAVA. I have realised 2 things, the first one is that I realy liked programming and the second is that I am not good at all. More specifically, I struggle on problem solving and when i face complex tasks I feel lost. Every day , I spend some quality time doing simple exercises in order to be more familiar with JAVA. My target is to become a good programmer and find a job on a software company. I am afraid maybe " I dont have it" thats why I am asking you , what should I do? Should i give up? Thanks in advance, Anestis

• what do you do when you are stuck at programming and you don't have access to internet? [migrated]

  - by minusSeven

  This is a question most of us have faced while programming. Getting stuck! It might be a programmatic problem or tool problem, most of us eventually face it. You know something is supposed to work some way but just doesn't. You tried a number of things to solve it but isn't helping and you are not sure why. I once remember being stuck hours at programming job. Eventually I figured out for some reason or other my IDE wasn't recompiling my new changes in some of the classes .This is just an example but I am sure most you have faced similar situation. So how would you go about solving it if you didn't have access to Google or Stack Exchange? Lets be honest, using internet you aren't solving the problem, somebody else is doing it for you. So if you didn't have access to internet or a friend who might help, how would you go about solving it?

• Raphael js text positioning: centering text in a circle

  - by j-man86

  Hey everyone, I am using Raphael js to draw circled numbers. The problem is that each number has a different width/height so using one set of coordinates to center the text isn't working. The text displays differently between IE, FF, and safari. Is there a dynamic way to find the height/width of the number and center it accordingly? Here is my test page: http://jesserosenfield.com/fluid/test.html and my code: function drawcircle(div, text) { var paper = Raphael(div, 26, 26); //<< var circle = paper.circle(13, 13, 10.5); circle.attr("stroke", "#f1f1f1"); circle.attr("stroke-width", 2); var text = paper.text(12, 13, text); //<< text.attr({'font-size': 15, 'font-family': 'FranklinGothicFSCondensed-1, FranklinGothicFSCondensed-2'}); text.attr("fill", "#f1f1f1"); } window.onload = function () { drawcircle("c1", "1"); drawcircle("c2", "2"); drawcircle("c3", "3"); }; Thanks very much!

• Paragraph formatting in a WPF RichTextBox?

  - by David Veeneman

  I need to apply paragraph formatting to a selection in a rich text box. My RTB will behave the same way as the rich text boxes on StackOverflow--the user can type text into the RTB, but they can also enter code blocks. The RTB will apply very simple formatting to the code block--it will change the font and apply a background color to the entire block, similar to what you see in the code block below. Changing the font is pretty straightforward: var textRange = new TextRange(rtb.Selection.Start, rtb.Selection.End); textRange.ApplyPropertyValue(TextElement.FontFamilyProperty, "Consolas"); textRange.ApplyPropertyValue(TextElement.FontSizeProperty, 10D ); Now I need to apply some paragraph-level formatting. I need to set the paragraph margin to 0, so I don't get a blank line between code lines, and I need to set the paragraph background color. Here's my problem: I can't figure out how to get the paragraph elements from the selection, so that I can apply formatting. Any suggestions? An example of how to apply the Margin and Background properties would be incredibly helpful. Thanks!

• WPF: disable inheritance of properties

  - by Maximilian Csuk

  Hi! I would like to use a TabControl as the main navigation in the application I am working on. So I would like to make the font in the headers of the TabItems bigger and also give it another background-color. However, I do not want this to be inherited. For example, if I use this code: <TabControl FontSize="18pt"> <TabItem Header="Tab 1"> <Button>Button 1</Button> </TabItem> </TabControl> The font in the button is also 18pt big. I know that this is normal dependency property behaviour because the property is inherited, but that's not what I want in this case. I would like to change the TabItems without changing anything in the children. Isn't that possible? Because re-setting all children to default values is a PITA. Thanks for your time.
