  • How to program a cutting tool for 3D model in game

    - by Jesse S
    I'm looking for a resource to figure out how to program a function to cut a 3d model in game. Example: Enemy/NPC is sliced into 2 pieces with a sword. His body is not hollow, you can see bloody texture where normally a 'polygon hole' would be. The first step is to actually 'cut/slice' the model, then add in polygons to fill the hole in the model. I know this can be done in 3D modelling software, but I'm not sure how to go about doing this in a game, code-wise. I do not wish to use 'pre cut-up" models, the code will determine where the cut is. Any pointers in the right direction would be greatly appreciated.

  • Microsoft XNA code sample wont work with blender model

    - by FreakinaBox
    I downloaded this code sample and integrated it into my game http://xbox.create.msdn.com/en-US/education/catalog/sample/mesh_instancing It works with the model that they supplied, but throws and exception whenever I use one of my models. The current vertex declaration does not include all the elements required by the current vertex shader. TextureCoordinate0 is missing. I tried pluging my model into their original source code and same thing. My model is an fbx from blender and has a texture. This is the function that throws the error GraphicsDevice.DrawInstancedPrimitives( PrimitiveType.TriangleList, 0, 0, meshPart.NumVertices, meshPart.StartIndex, meshPart.PrimitiveCount, instances.Length );

  • Basic/research RTS engine/model

    - by XTF
    Does a basic/research RTS engine/model exist that can be used as a basis for further experimentation/research? I'd like to avoid reinventing the wheel if possible. I'm aware of Spring Engine and Stratagus, but those are real game engines and may not be the best to experiment with and learn from. Ideally the docs for the model would answer questions like: How exactly do units move? (constant velocity? constant acceleration? constant force?) How is pathfinding handled? Does every grid cell become an A* graph node (may be expensive)? Does it consider threats? How are groups handled? (w.r.t pathfinding and movement) How is combat handled? I'm mostly interested in the low-level model details (for now), not the graphics etc. I've read a lot of the other quesions (and answers/references) tagged RTS but I haven't found my answer yet.

  • Two view App with root template view

    - by Tieman
    Hi I was wanted to do Application witch have a root template view with a nice logo on top or something adn load other views just below (here is what I have right now: Test App ) But I have a little problem. If I'll remove a comment in file TestAppDelegate.m on line 58 //[currentView release]; Application will crash with bunch of errors when I try to switch views. But if I comment this line Project analyzer is telling me that I have a potential leak with currentView variable. Can somebody spare some time and see in that code what I did wrong?

  • DDD and MVC: Difference between 'Model' and 'Entity'

    - by Nathan Loding
    I'm seriously confused about the concept of the 'Model' in MVC. Most frameworks that exist today put the Model between the Controller and the database, and the Model almost acts like a database abstraction layer. The concept of 'Fat Model Skinny Controller' is lost as the Controller starts doing more and more logic. In DDD, there is also the concept of a Domain Entity, which has a unique identity to it. As I understand it, a user is a good example of an Entity (unique userid, for instance). The Entity has a life-cycle -- it's values can change throughout the course of the action -- and then it's saved or discarded. The Entity I describe above is what I thought Model was supposed to be in MVC? How off-base am I? To clutter things more, you throw in other patterns, such as the Repository pattern (maybe putting a Service in there). It's pretty clear how the Repository would interact with an Entity -- how does it with a Model? Controllers can have multiple Models, which makes it seem like a Model is less a "database table" than it is a unique Entity. So, in very rough terms, which is better? No "Model" really ... class MyController { public function index() { $repo = new PostRepository(); $posts = $repo->findAllByDateRange('within 30 days'); foreach($posts as $post) { echo $post->Author; } } } Or this, which has a Model as the DAO? class MyController { public function index() { $model = new PostModel(); // maybe this returns a PostRepository? $posts = $model->findAllByDateRange('within 30 days'); while($posts->getNext()) { echo $posts->Post->Author; } } } Both those examples didn't even do what I was describing above. I'm clearly lost. Any input?

  • ASP.NET MVC 2 loading partial view using jQuery - no client side validation

    - by brainnovative
    I am using jQuery.load() to render a partial view. This part looks like this: $('#sizeAddHolder').load( '/MyController/MyAction', function () { ... }); The code for actions in my controller is the following: public ActionResult MyAction(byte id) { var model = new MyModel { ObjectProp1 = "Some text" }; return View(model); } [HttpPost] public ActionResult MyAction(byte id, FormCollection form) { // TODO: DB insert logic goes here var result = ...; return Json(result); } I am returning a partial view that looks something like this: <% using (Html.BeginForm("MyAction", "MyController")) {%> <%= Html.ValidationSummary(true) %> <h3>Create my object</h3> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%= Html.LabelFor(model => model.ObjectProp1) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Size.ObjectProp1) %> <%= Html.ValidationMessageFor(model => model.ObjectProp1) %> </div> div class="editor-label"> <%= Html.LabelFor(model => model.ObjectProp2) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.ObjectProp2) %> <%= Html.ValidationMessageFor(model => model.ObjectProp2) %> </div> <p> <input type="submit" value="Create" /> </p> </fieldset> <% } %> Client side validation does not work in this case. What is more the script that contains validation messages also isn't included in the view that's returned. Both properties in my model class have Required and StringLength attributes. Is there any way to trigger client side validation in a view which has been loaded like this?

  • Eclipse Outline View - Visible JavaScript Categories in Eclipse?

    - by leeand00
    I just found an option in the little white down arrow in Eclipse that reads "Visible Categories..." How can I use this? It seems to me that it could be used to only show functions that have an @category in their comments, but I haven't been able to make that work. If it did work it would be incredibly useful for separating out Unit Tests from their common-functions and separating them from the setUp and tearDown methods, so what is it really for? By the way I'm editing a Javascript file in the Eclipse "Javascript Editor", I don't know if that makes any difference or not.

  • Android Custom View Constructor

    - by Mitch
    I'm learning about using Custom Views from the following: http://developer.android.com/guide/topics/ui/custom-components.html#modifying The description says: Class Initialization As always, the super is called first. Furthermore, this is not a default constructor, but a parameterized one. The EditText is created with these parameters when it is inflated from an XML layout file, thus, our constructor needs to both take them and pass them to the superclass constructor as well. Is there a better description? I've been trying to figure out what the constructor(s) should look like and I've come up with 4 possible choices (see example at end of post). I'm not sure what these 4 choices do (or don't do), why I should implement them, or what the parameters mean. Is there a description of these? Thanks. Mitch public MyCustomView() { super(); } public MyCustomView(Context context) { super(context); } public MyCustomView(Context context, AttributeSet attrs) { super(context, attrs); } public MyCustomView(Context context, AttributeSet attrs, Map params) { super(context, attrs, params); }

  • Rails: Skinny Controller vs. Fat Model, or should I make my Controller Anorexic?

    - by Nick Gorbikoff
    I know similar questions have been answered before - such as: Where should logic go, where to do certain tasks, etc. But I have a more specific question - How far should I take this axiom: "keep your controller skinny, make your model fat!" Here is an example: For instance let's say I have multiple source of verification data. A good example would be a VIN number - I can verify it against, manufacturers data source, DMV's data source, also my local databases - to see what I have on record. So I have a model called Vin and vins_controller. Inside the model I have 5 methods: check_against_local_db, check_against_dmv, check_against_car_maker_1, check_against_car_maker_2, etc. In my controller keeping with the REST, in action show - I have a simple case statement which looks at the params[:source], and based on source specified - will call specific check method. Now here is the question: Should I leave the logic that governs which data source to call in controller or should I move it to model and then in controller just do something like check_vin(source, vin)? Should I make my controller anorexic?

  • Asp.Net MVC2 Model Binding Problem.

    - by Pino

  • Integrate IPhone Safari like view in Android?

    - by sunil
    The main concept goes like this. I have four listviews with its own data loaded at the same time. Only one listview will be visible to the user. Now, when the user presses a button, not only the current listview but also other three listviews should be minimized and then user can just scroll just as in Gallery and select the listview that one wants to open. I hope you all have understood what I want. Let me know if someone have some idea of implementing such a User Interface in Android. Thanks & Regards Sunil

  • Model Binding to a List using non-sequential indexes. Can I access the index later?

    - by Kid A
    I'm following Phil's great tutorial on model binding to a list. I use input names like this: book[5804].title book[5804].author book[1234].title book[1234].author This works well and the data gets back to the model just fine, populating a list of books. What I'm looking for is a way to get access in the model to the index that was used to send the books. I'd like to get that number, "5804." This is because the index is of semantic importance. If I can access it, it saves me from setting another property on the object (book ID). Is there a way to see, either on the FormCollection or on the model after UpdateModel is called, what the index was when it was sent up?

  • avoid preselection of a view when focus is gained android

    - by Sephy
    Hi all, I don't know if the title is very clear, but my issue is as follows : I have an activity with a listview, and on top of this listview, i have a searchfield (edittext). The issue is that when i try debugging on a phone, the virtual keyboard gets out straight after the screen displays the activity... And of course, it's hidding half of the list... So, is there an attribute or something I can use to prevent this from happening?(I still want to keybord to appear when i click the edittext though...) thank you

  • iOS: Gesture recogniser for smooth scrolling and flicking a View

    - by AppleDeveloper
    I am building an iPad app where I needed to allow resizing views functionality using divider view provided between two views. This divider view is just a 20px height view between two half screen content views - please refer attached images. When user scrolls this divider view up or down, both content views changes their sizes appropriately. I have extended UIView and implemented this using touchMoved delegate as code given below in touchesMoved delegate. It works fine. The only thing is missing with TouchMoved is you can't flick divider view to top or bottom directly. You have to scroll all the way to top or bottom! To support flicking the view I have tried UIPanGestureRecognizer but I don't see smooth scrolling with it. When I handle split position change in UIGestureRecognizerStateChanged state, just touching divider view flick it to top or bottom. Handling split position change in UIGestureRecognizerStateEnded does the same but I don't see content view resizing with dividerview scrolling! Could someone please tell me how could I achieve both smooth scrolling of divider view with resizing content views(like touchMoved) and flicking the view. Any alternative approach would also fine. Thanks. - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; if (touch) { CGPoint lastPt = [touch previousLocationInView:self]; CGPoint pt = [touch locationInView:self]; float offset = pt.y - lastPt.y; self.parentViewController.splitPosition = self.parentViewController.splitPosition + offset; } } - (void)handlePan:(UIPanGestureRecognizer*)recognizer { CGPoint translation = [recognizer translationInView:recognizer.view]; CGPoint velocity = [recognizer velocityInView:recognizer.view]; if (recognizer.state == UIGestureRecognizerStateBegan) { } else if (recognizer.state == UIGestureRecognizerStateChanged) { // If I change split position here, I don't see smooth scrolling dividerview...it directly jumps to the top or bottom! self.parentViewController.splitPosition = self.parentViewController.splitPosition + translation.y; } else if (recognizer.state == UIGestureRecognizerStateEnded) { // If I change split position here, the same thing happens at end and I don't see my divider view moving with my scrolling and resizing my views. self.parentViewController.splitPosition = self.parentViewController.splitPosition + translation.y; } } Initial screen Increased top view size by scrolling divider view Top view is totally hidden here but I have to scroll divider view all the way to top. I want to flick the divider view so that it directly goes from any position to top

  • android: Check if a View is bringed to front

    - by user329692
    Hi Guys! I made a custom component which simple extends a WebView This component is used into activities that are loaded from a tabhost. This component creates a timertask too. I'd like to execute the task only if the activity that contains the component is visible. Ex: public class MyWebView extends WebView { public MyWebView(Context context, AttributeSet as) { super(context,as); /** More code **/ TimerTask ttask = new TimerTask() { @Override public void run() { if (iamvisible) doStuff(); } }; timer = new Timer(); timer.schedule(ttask, refreshInterval * 1000, refreshInterval * 1000); } } How can I set the iamvisible variable? I tried overriding onWindowFocusChanged and onWindowVisibilityChanged but with no luck Regards in advance

  • How to prevent modal view controllers flashing when changing

    - by KP Overflow
    I have three view controllers, let's call them A, B and C. When a button is pressed on view A, view B is shown using presentModalViewController:animated: When the finish button is pressed on screen B, it dismisses itself. View A is notified whereupon it immediately shows view C, again using presentModalViewController:animated: The problem is that view A's content is momentarily flashed on the screen between view B closing and view C opening. I can get around this by making view A blank and moving it's current content to a new view, D. (For various reasons, I don't want view B to own view C, that's why it's not opening it) Am I over-complicating this? I'm sure there is a smarter way to go? ThanksT

  • Initializing Detail View from nib with parameters passed from Root View

    - by culov
    I'm have a map view with a number of annotations on it... once the callout is clicked, i need to pass several parameters to the DetailViewController, so ive been trying to do this through the constructor. I've debugged a bit and discovered that the arguments are being passed properly and are being received as expected within the constructor, but for some reason whenever I try to change the values of the IBOutlets I've positioned in the nib, it never has an effect. Here's what im passing (btw, im getting a "No initWithNibName : bundle : header' method found" warning at this line): DetailViewController *dvc = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil header:headerText]; [self.navigationController pushViewController:dvc animated:YES]; Now heres my constructor: - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil header:(UILabel*)headerLabel { if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) { self.headerTextView = headerLabel; NSLog(@"header:%@", headerLabel.text); } return self; } Once again, the problem is that headerLabel.text is printed properly in the console, but the line self.headerTextView = headerLabel; doesnt seem to be doing what I want it to do. Thanks!

  • How to handle authorization in the view layout

    - by mathk
    Authorize attribute are good to do some access control base on Action but suppose that I have some UI element in the layout that should note be output unless the user is authorize. I could possibly set some boolean in the ViewBag but that is not the good solution I guess. Somewhere in the Layout.cshtml: @if (ViewBag.IsAuthorized) { <li>@Html.ActionLink("Index", "Admin")</li> } Let me know if there is a better solution. Thanks.

  • Multiple View application and Navigation Bar

    - by byronh
    Hi. I'm working in a iphone view-based application. The application works this way: First view is a welcome view with buttons for load other views. Second view is a map that shows the location using gps. Third view is a search engine that loads some information to show on the map and on a list (This has two button to load map or table). Fourth view is a table view that shows the results and then loads the detail on another view and load a web site on another view. My problem is with this view, because i don't know how can implement a navigation bar in this view that loads the detail and the web view. Thanks for your help. Byron H.
