  • C++ constructor problem, values not being set

    - by 2Real
    Hi, I'm new to C++ and I'm trying to figure out this problem I'm having with my constructor for one of my classes. What happens is... all my variables are initialized properly except two (health and type). #pragma once #include <irrlicht.h> #include <vector> #include <cassert> using namespace irr; using namespace core; using namespace scene; enum { PLAYER = 0, NPC = 1, SOLDIER = 2, CHAINGUNNER = 3 }; class Model { public: Model(void); Model(int id, std::vector<ISceneNode*> modelVec, int modType); ~Model(void); std::vector<int> path; std::vector<ISceneNode*> model; int endNode; int type; int animate; int health; u32 lastAnimation; private: int mId; }; #include "Model.h" Model::Model(void) { //assert(false); } Model::Model(int id, std::vector<ISceneNode*> modelVec, int modType) { path = std::vector<int>(); model = modelVec; endNode = 0; type = modType; animate = 0; health = 100; lastAnimation = 0; mId = id; } Model::~Model(void) {} I create a model with Model soldier(id, model, SOLDIER) Everything is set properly except type and health. I've tried many different things, but I cannot figure out my problem. I'm not sure but the default constructor is being called. It doesn't make sense because I make no called to that constructor. Thanks,

  • Is it possible to make the iPhone keyboard invisible / remove it without resigning first responder?

    - by Alex Gosselin
    I am looking for a way to show my own input view (a UITableView) to enter certain keywords in a UITextView faster than typing them, and also be able to type into this text view the normal way. My solution has a button that causes the keyboard to disappear, revealing the table view underneath it. Problem is I can't figure out how to make the keyboard go away without resigning first responder, and losing the cursor. Has anyone accomplished this before? Thanks for any help.

  • Hook perm for more than one content type

    - by Andrew
    Drupal 6.x I have this module that manages four different content types. For that matter, how do I define permission for each content within the same module? Is that even possible? I can't figure out how to define permission for each content type cuz hook_perm has to be named with module name and it doesn't have any argument(like hook_access $node) to return permission base on content type. Any help would be highly appreciated.

  • HTML5 elements working in Chrome but not Safari or Firefox?

    - by Chris Armstrong
    Hi, I'm using the HTML5 elements and in a project i'm working on (see it here) and the css seems to be working fine in Chrome. However, it doesn't appear to be working in Safari or Firefox (I haven't tested IE, but I'd imagine it's the same), and the page layout is all over the place. Any ideas why this may be? I know Firefox and Safari both support these elements, and Safari is webkit-based like Chrome, so I can't figure out what the problem is.

  • Does the iPhone 3G/3Gs camera put metadata in its images? (and how do you get it?)

    - by Ben Collins
    I've been trying to figure how whether the iPhone (either 3G or 3Gs) camera puts metadata into it's images. Anecdotally, it appears that it does (e.g., I've seen images posted on the web that included a bunch of metadata), but I can't find reference to it anywhere in the SDK documentation. So....does anyone have a definitive answer? Also, if there is metadata, how do I get at it?

  • How to show printer properties/preferences dialog and save changes?

    - by Patrick Klug
    I can't figure out how to properly show the printer preference dialog of a given printer so that the user can change the printer settings. Most of the examples that I can find online manage to show the dialog but any changes the user might make are lost which makes it useless. Example: http://www.codeproject.com/KB/system/PrinterPropertiesWindow.aspx (I tried to change the code as suggested by BartJoy but that didn't fix it) Does anyone know how to do this properly?
