  • Cocos2d-x v3 invalid conversion from 'cocos2d::Layer* [on hold]

    - by Hammerh5
    Hello guys I'm learning cocos2d-x v3 right but most of the code that I can find is to the version 2. My specific error is this one, when I try to compile my cocos2s-x 3 project this error shows. invalid conversion from 'cocos2d::Layer to Game* [-fpermisive]* What I want to do is create a new game scene in the following code: //Game.cpp #include "Game.h" Scene* Game::scene() { scene *sc = CCScene::create(); sc->setTag(TAG_GAME_SCENE); const Game *g = Game::create(); //Here is where the conversions fails. sc->addChild(g, 0, TAG_GAME_LAYER); return sc; } Of course this is my header file //Game.h #include "cocos2d.h" #include "Mole.h" #include "AppDelegate.h" using namespace cocos2d; class Game: public cocos2d::Layer { cocos2d::CCArray *moles; float timeBetweenMoles, timeElapsed, increaseMolesAtTime, increaseElapsed, lastMoleHiTime; int molesAtOnce; cocos2d::CCSize s; bool isPaused; public: CCString *missSound, *hitSound; static cocos2d::Scene* scene(); virtual bool init(); void showMole(); void initializeGame(); void onEnterTransitionDidFinish(); void onExit(); void onTouchesBegan(const std::vector<cocos2d::Touch *> &touches, cocos2d::Event *event); void tick(float dt); cocos2d::CCArray* getMoles(bool isUp); //LAYER_CREATE_FUNC(Game); }; #endif /* GAME_H_ */ I don't know what's wrong I suppose this code works fine in Cocos2d-x v2. It's maybe some changes in the C++ version ?

  • new line in a multi-line string

    - by Zka
    Trying to override a tostring in one of my classes. return string.Format(@" name = {0} ID = {1} sec nr = {2} acc nr = {3}", string, int, int ,int); // types But the thing is, the result isn't aligned when printed out: name = test ID = 42 sec nr = 11 acc nr = 55 Trying to add \n just prints it out without formating. Guessing it has something to do with @"" which I'm using for multi-lining. Would like it to print out : name = test ID = 42 sec nr = 11 acc nr = 55

  • Open Source multi-touch API's?

    - by daft
    I'm looking for a good open source multi-touch API to use in a project we might get. So far I've found PyMT, but haven't really seen any comments on the maturity of that product, so any input in that regard would be much appreciated. I'd also like some other suggestions on API's that might be of interest, since googling have only given so much, and as with PyMT, it is quite difficult finding opinions on the frameworks out there. Many thanks.

  • Django Multi-Table Inheritance VS Specifying Explicit OneToOne Relationship in Models

    - by chefsmart
    Hope all this makes sense :) I'll clarify via comments if necessary. Also, I am experimenting using bold text in this question, and will edit it out if I (or you) find it distracting. With that out of the way... Using django.contrib.auth gives us User and Group, among other useful things that I can't do without (like basic messaging). In my app I have several different types of users. A user can be of only one type. That would easily be handled by groups, with a little extra care. However, these different users are related to each other in hierarchies / relationships. Let's take a look at these users: - Principals - "top level" users Administrators - each administrator reports to a Principal Coordinators - each coordinator reports to an Administrator Apart from these there are other user types that are not directly related, but may get related later on. For example, "Company" is another type of user, and can have various "Products", and products may be supervised by a "Coordinator". "Buyer" is another kind of user that may buy products. Now all these users have various other attributes, some of which are common to all types of users and some of which are distinct only to one user type. For example, all types of users have to have an address. On the other hand, only the Principal user belongs to a "BranchOffice". Another point, which was stated above, is that a User can only ever be of one type. The app also needs to keep track of who created and/or modified Principals, Administrators, Coordinators, Companies, Products etc. (So that's two more links to the User model.) In this scenario, is it a good idea to use Django's multi-table inheritance as follows: - from django.contrib.auth.models import User class Principal(User): # # # branchoffice = models.ForeignKey(BranchOffice) landline = models.CharField(blank=True, max_length=20) mobile = models.CharField(blank=True, max_length=20) created_by = models.ForeignKey(User, editable=False, blank=True, related_name="principalcreator") modified_by = models.ForeignKey(User, editable=False, blank=True, related_name="principalmodifier") # # # Or should I go about doing it like this: - class Principal(models.Model): # # # user = models.OneToOneField(User, blank=True) branchoffice = models.ForeignKey(BranchOffice) landline = models.CharField(blank=True, max_length=20) mobile = models.CharField(blank=True, max_length=20) created_by = models.ForeignKey(User, editable=False, blank=True, related_name="principalcreator") modified_by = models.ForeignKey(User, editable=False, blank=True, related_name="principalmodifier") # # # Please keep in mind that there are other user types that are related via foreign keys, for example: - class Administrator(models.Model): # # # principal = models.ForeignKey(Principal, help_text="The supervising principal for this Administrator") user = models.OneToOneField(User, blank=True) province = models.ForeignKey( Province) landline = models.CharField(blank=True, max_length=20) mobile = models.CharField(blank=True, max_length=20) created_by = models.ForeignKey(User, editable=False, blank=True, related_name="administratorcreator") modified_by = models.ForeignKey(User, editable=False, blank=True, related_name="administratormodifier") I am aware that Django does use a one-to-one relationship for multi-table inheritance behind the scenes. I am just not qualified enough to decide which is a more sound approach.

  • django multi-language (i18n) and seo

    - by fumer
    hi, I am developing a multi-language site in django. In order to improve SEO, i will give every language version a unique URL like below, english: www.foo.com/en/index.html french: www.foo.com/fr/index.html chinese: www.foo.com/zh/index.html However, Django looks for a "django_language" key in user's session or cookie to determine language in default, so,Despite which language user chose, URL is always the same. for instance: http://www.foo.com/index.html how to resolve this problem ? thank you!

  • Open Source or Low Cost Layer 7 ("Content") Switch?

    - by Rob
    I have several web servers that host a number of different applications and web sites. I want to make it easy to host apps or parts of web sites on different servers (e.g. example.com/foo might be on one physical server and example.com/bar might be on another). We do this Apache redirects right now, but that gets messy fast and in any case we have other problems we want to solve, such as throttling requests from individual clients, and reducing dependency on specific physical hosts. Is there an open source or low cost layer 7 switch that would be suitable for this sort of task? I was hoping to find something like a stripped down Linux VMware guest/appliance built for this purpose, but haven't seen anything suitable out there so far.

  • How to Test a Multi-Tenant App with support for multiple domains

    - by asifch
    HI, we are building a multi-tenant application, which will support that each tenant can have a unique top level domain, the application is build using the asp.net 3.5 and SQL servr 2005, while each tenant will have different database. I have seen a number of questions about the similar applications on the StackOverFlow, but none of them is related to the Testing, I want to know is how one can test the application in a development environment, specially How can we test that each customer connects to his own DB based on the URL. how can we emulate different domains on the local system. like abc.com and xyz.com all goes to dev machine's IIS. Any recommendations which might help us in the developing process of such an application.

  • Injecting tenant repositories with StructureMap in a multi-tenant MVC applicaiton

    - by FreshCode
    I'm implementing StructureMap in a multi-tenant ASP.NET MVC application to inject instances of my tenant repositories that retrieve data based on an ITenantContext interface. The Tenant in question is determined from RouteData in a base controller's OnActionExecuting. How do I tell StructureMap to construct TenantContext(tenantID); where tenantID is derived from my RouteData or some base controller property? Base Controller Given the following route: {tenant}/{controller}/{action}/{id} My base controller retrieves and stores the correct Tenant based on the {tenant} URL parameter. Using Tenant, a repository with an ITenantContext can be constructed to retrieve only data that is relevant to that tenant. Based on the other DI questions, could AbstractFactory be a solution?

  • Multi tenancy with Unity

    - by Savvas Sopiadis
    Hi everybody! I'm trying to implement this scenario using Unity and i can't figure out how this could be done: the same web application (ASP.NET MVC) should be made accessible to more than one client (multi-tenant). The URL of the web site will differentiate the client (this i know how to get). So getting the URL one could set the (let's call it) IConnectionStringProvider parameter (which will be afterward injected into IRepository and so on). Through which mechanism (using Unity) do i set the IConnectionStringProvider parameter at run time? I have done this in the past using Windsor & IHandlerSelector (see this) but it's my first attempt using Unity. Any help is deeply appreciated! Thanks in advance

  • How can I create and manage a multi-tenant ASP MVC application

    - by Wizzarding
    Hi, I want to create a multi-tenant application that uses the hostname to determine the customer. For example: CustomerOne.myapp.com AnotherCo.myapp.com AndOneMore.myapp.com ... I can do the database and security side with no problems, I can also get the hostname from the URL, but what I am struggling to find out is how to create the basic plumbing that would allow a new customer to sign up online, provide their company name, and for the application to create the new URL, ready to be used straight away. Can anyone help? Thanks, Rob.

  • performance monitoring tools for multi-tenant web application

    - by Anton
    We have a need to monitor performance of our java web app. We are looking for some tolls which can help us with this task. The major difficulty is that we are SaaS provider with multi-tenant server architecture with hundreds of customers running on the same hardware. So far we tried commercial products like DynaTrace and Coradinat but unfortunately they don't get the job done so far. What we need is a simple report which would tell us if we had performance problems on each customer site in a specified period of time. Mostly it will be response time per customer but also we will need some more specifics based on the URLs. please let me know if someone had any experience with setting up such monitoring. Thanks!

  • Data-separation in a Symfony Multi-tenant app using Doctrine

    - by Prasad
    I am trying to implement a multi-tenant application, that is - data of all clients in a single database - each shared table has a tenant_id field to separate data I wish to achieve data separation by adding where('tenant_id = ', $user->getTenantID()) {pseudoc-code} to all SELECT queries I could not find any solution up-front, but here are possible approaches I am considering. 1) crude approach: customizing all fetchAll and fetchOne functions in every class (I will go mad!) 2) using listeners: possibly coding for the preDqlSelect event and adding the 'where' to all queries 3) override buildQuery(): could not find an example of this for front-end 4) implement contentformfilter: again need a pointer Would appreciate if someone could validate these & comment on efficieny, suitability. Also, if anyone has achieved multitenancy using another strategy, pl share. Thanks

  • Isometric layer moving inside map

  • Using macro as an abstraction layer

    - by tehnyit
    I am having a discussion with a colleague about using macro as a thin (extremely) layer of abstraction vs using a function wrapper. The example that I used is Macro way. #define StartOSTimer(period) (microTimerStart(period)) Function wrapper method void StartOSTimer(period) { microTimerStart(period); } Personally, I liked the second method as it allows for future modification, the #include dependencies are also abstracted as well.

  • Trying to use stencils in 2D while retaining layer depth

    - by Steve
    This is a screen of what's going on just so you can get a frame of reference. http://i935.photobucket.com/albums/ad199/fobwashed/tilefloors.png The problem I'm running into is that my game is slowing down due to the amount of texture swapping I'm doing during my draw call. Since walls, characters, floors, and all objects are on their respective sprite sheet containing those types, per tile draw, the loaded texture is swapping no less than 3 to 5+ times as it cycles and draws the sprites in order to layer properly. Now, I've tried throwing all common objects together into their respective lists, and then using layerDepth drawing them that way which makes things a lot better, but the new problem I'm running into has to do with the way my doors/windows are drawn on walls. Namely, I was using stencils to clear out a block on the walls that are drawn in the shape of the door/window so that when the wall would draw, it would have a door/window sized hole in it. This is the way my draw was set up for walls when I was going tile by tile rather than grouped up common objects. first it would check to see if a door/window was on this wall. If not, it'd skip all the steps and just draw normally. Otherwise end the current spriteBatch Clear the buffers with a transparent color to preserve what was already drawn start a new spritebatch with stencil settings draw the door area end the spriteBatch start a new spritebatch that takes into account the previously set stencil draw the wall which will now be drawn with a hole in it end that spritebatch start a new spritebatch with the normal settings to continue drawing tiles In the tile by tile draw, clearing the depth/stencil buffers didn't matter since I wasn't using any layerDepth to organize what draws on top of what. Now that I'm drawing from lists of common objects rather than tile by tile, it has sped up my draw call considerably but I can't seem to figure out a way to keep the stencil system to mask out the area a door or window will be drawn into a wall. The root of the problem is that when I end a spriteBatch to change the DepthStencilState, it flattens the current RenderTarget and there is no longer any depth sorting for anything drawn further down the line. This means walls always get drawn on top of everything regardless of depth or positioning in the game world and even on top of each other as the stencil has to happen once for every wall that has a door or window. Does anyone know of a way to get around this? To boil it down, I need a way to draw having things sorted by layer depth while also being able to stencil/mask out portions of specific sprites.

  • VLAN ACLs and when to go Layer 3

    - by wuckachucka
    I want to: a) segment several departments into VLANs with the hopes of restricting access between them completely (Sales never needs to talk to Support's workstations or printers and vice-versa) or b) certain IP addresses and TCP/UDP ports across VLANS -- i.e. permitting the Sales VLAN to access the CRM Web Server in the Server VLAN on port 443 only. Port-wise, I'll need a 48-port switch and another 24-port switch to go with the two existing 24-port Layer 2 switches (Linksys); I'm looking at going with D-Links or HP Procurves as Cisco is out of our price range. Question #1: From what I understand (and please correct me if I'm wrong), if the Servers (VLAN10) and Sales (VLAN20) are all on the same 48-port switch (or two stacked 24-port switches), afaik, the switch "knows" what VLANs and ports each device belongs to and will switch packets between them; I can also apply ACLs to restrict access between VLANs at this point. Is this correct? Question #2: Now lets say that Support (VLAN30) is on a different switch (one of the Linksys) switches. I'm assuming I'll need to trunk (tag) switch #2's VLANs across to switch #1, so switch #1 sees switch #2's VLAN30 (and vice-versa). Once Switch #1 can "see" VLAN30, I'm assuming I can then apply ACLs as stated in Question #1. Is this correct? Question #3: Once Switch #1 can see all the VLANs, can I achieve the seemingly "Layer 3" ACL filtering of restricting access to Server VLAN on only certain TCP/UDP ports and IP addresses (say, only permitting 3389 to the Terminal Server, 192.168.10.4/32). I say "seemingly" because some of the Layer 2 switches mention the ability to restrict ports and IP addresses through the ACLs; I (perhaps mistakenly) thought that in order to have Layer 3 ACLs (packet filtering), I'd need to have at least one Layer 3 switch acting as a core router. If my assumptions are incorrect, at which point do you need a Layer 3 switch for inter-VLAN routing vs. inter-VLAN switching? Is it generally only when you need that higher-level packet filtering ability between your departments?

  • Different subnets routing with just one layer 3 switch

    - by GustavoFSx
    Our current network looks like this: Location 1: 2 Layer 2 switches | subnet 192.168.1.0/24 | Firewall for our VPN Location 2: 1 Layer 2 switch | subnet 192.168.3.0/24 | Firewall for our VPN Location 3: 1 Layer 2 switch | subnet 192.168.5.0/24 | Firewall for our VPN We just got a direct fiber connection between location 1 and 2, we also got a new HP V1910 24G layer 3 switch. I tried to follow the instructions on this site, but I can't get it to work. I think our network should look like this: Location 1: HP Switch FIBER to L2 | subnet 192.168.1.0/24 | Firewall for our VPN Location 2: 1 Layer 2 switch | subnet 192.168.3.0/24 | FIBER to L1 Location 3: 1 Layer 2 switch | subnet 192.168.5.0/24 | Firewall for our VPN So, how can I get routing working on our location 2? It's old gateway was a firewall device on ip 192.168.3.1. I'm thinking on creating a VLAN Interface on 192.168.3.1 on the switch for the Location 2. But how will I handle that on the HP switch that has a direct fiber connection with that switch? Please help, I'm not very good with networking.
